Current Clinical Dental Practice Guidelines and the Financial Impact of COVID-19 on Dental Care Providers

Dental service utilization and the COVID-19 pandemic, a micro-data analysis

BACKGROUND

Global crises and disease pandemics, such as COVID-19, negatively affect dental care utilization by several factors, such as infection anxiety, disrupted supply chains, economic contraction, and household income reduction. Exploring the pattern of this effect can help policy makers to be prepared for future crises. The present study aimed to investigate the financial impact of COVID-19 disruptions on dental service utilization.

METHODS

Data on the number of dental services offered in Dental School Clinics of Tehran University of Medical Sciences was collected over a period of two years, before and after the initial COVID-19 outbreak in Iran. School of Dentistry operates two clinics; one with competitive service fees and one with subsidies. Regression analyses were performed to determine the effect of the pandemic on the number of dental services divided by dental treatment groups and these clinics. The analyses were adjusted for seasonal patterns and the capacity of the clinics.

RESULTS

There was a significant drop in dental services offered in both clinics across all dental groups in the post-COVID period (on average, 77 (39.44%) fewer services per day). The majority of the procedure loss happened in the Private clinic. Adjusting for seasonal patterns and the service capacity, regression results documented 54% and 12% service loss in Private and Subsidized clinics following the pandemic, respectively. Difference-in-difference analysis documented that the Subsidized clinic performed 40% more treatments than the Private clinic in the post-COVID period.

CONCLUSIONS

Pandemic -reduction in dental care utilization could have long-term ramifications for the oral health of the population, and policymakers need to provide supportive packages to the affected segments of the economy to reverse this trend.

General public awareness, knowledge and attitude toward COVID-19 infection and prevention: a cross-sectional study from Pakistan

Background: The aim of this study is to evaluate the knowledge, perceptions, and attitude of the public in Pakistan (using social media) towards COVID-19. Methods: A cross-sectional study was conducted amongst 1120 individuals nationwide. A self-developed, pre-tested questionnaire was used that comprised of sections covering demographic characteristics, medical history, hygiene awareness, COVID-19-related knowledge, and learning attitude. Descriptive statistics were used for frequencies, percentages, averages and standard deviations. Inferential statistics were done using the Student's t-test and ANOVA. Results: The average age of participants was 31 years (range 18-60 years). In total 56 individuals (5%) had completed primary or secondary school education; 448 (40%) were employed (working from home) and 60% were jobless due to the COVID-19 crisis. Almost all the study subjects (1030 (92%)) were washing their hands multiple times a day. A total of 83% had awareness regarding quarantine time, 82% used face masks whenever they left their homes, 98% were aware of the origin of the disease, and 70% had knowledge regarding the most common symptoms of COVID-19. Conclusion: It can be concluded from the current study that female participants had higher level of education, and more awareness regarding the coronavirus. The majority of the participants followed proper hand washing regimes and washed their faces. Further knowledge and awareness should be promoted.

Trends in dental insurance claims in the United States in the context of the COVID-19 pandemic: A 3-year perspective (2019-2022)

OBJECTIVES

We showed in a previous analysis the patterns of disruption for private dental insurance claims in the United States caused by the SARS-CoV-2 pandemic in 2020. The present report examines trends during 2020 and 2021, that is, contrasting perspectives during 2019 with the acute phase of the pandemic in 2020, and 2021.

METHODS

Private dental insurance paid claims from a data warehouse were obtained, encompassing a 5% random sample of records between January 2019 and December 2021 for child and adult insureds who filed a claim in 2019, 2020, and 2021. We classified claims into one of four categories based on the likelihood of being associated with urgent/emergency care.

RESULTS

The precipitous reduction in dental care claims in March-June 2020 recovered to almost pre-pandemic levels by the fall of 2020. However, a downward decline in private dental insurance claims started in the late fall of 2020 and continued through 2021. Differential impacts in dental care categories-in terms of urgency of care-were evident 2021, closely resembling previous trends in 2020.

CONCLUSIONS

Dental care claims from the first year of the 2020 SARS-CoV-2 pandemic were contrasted with perspectives in 2021. A downward trend in demand/availability changes in dental care insurance claims set in for 2021, perhaps linked to perceptions of the overall economic situation. Such downward trend has continued overall, even after considering seasonal changes and the acceleration of the pandemic during the Delta, Omicron, and other variants.

Perception of Remote Learning by Fixed Prosthodontic Students at a Romanian Faculty of Dentistry

The COVID-19 pandemic has forced the transfer of traditional on-site educational activities to the online environment. This study aimed to evaluate the perception and acceptance of remote learning among fixed prosthodontic students attending the Faculty of Dental Medicine of "Grigore T. Popa" University of Medicine and Pharmacy in Iasi, Romania, and to analyze the feedback regarding their experience with the new online methods, the perceived quality thereof and suggestions for improvement. An observational cross-sectional, online study based on 22 questions was conducted with 259 students. The general opinion of online education was good or very good (40.15%); regarding its efficiency, 28.57% found it efficient while 34.36% found it inefficient or very inefficient; regarding the pleasure of learning online, 45.95% of students enjoyed online learning, while 36.64% did not enjoy it. The problem that was most cited by respondents was that of keeping all students motivated and involved (65.6%). Sixty-two percent of the respondents believe that online dental education should not exist, or just to a small extent, a result justified by the practical nature of the profession. The general opinion was that health risks should be managed and mitigated by using a hybrid system that would allow students to do on-site clinical training with direct contact with patients.

Mouth rinses efficacy on salivary SARS-CoV-2 viral load: A randomized clinical trial

Considering the global trend to confine the COVID-19 pandemic by applying various preventive health measures, preprocedural mouth rinsing has been proposed to mitigate the transmission risk of SARS-CoV-2 in dental clinics. The study aimed to investigate the effect of different mouth rinses on salivary viral load in COVID-19 patients. This study was a single-center, randomized, double-blind, six-parallel-group, placebo-controlled clinical trial that investigated the effect of four mouth rinses (1% povidone-iodine, 1.5% hydrogen peroxide, 0.075% cetylpyridinium chloride, and 80 ppm hypochlorous acid) on salivary SARS-CoV-2 viral load relative to the distilled water and no-rinse control groups. The viral load was measured by quantitative reverse transcription PCR (RT-qPCR) at baseline and 5, 30, and 60 min post rinsing. The viral load pattern within each mouth rinse group showed a reduction overtime; however, this reduction was only statistically significant in the hydrogen peroxide group. Further, a significant reduction in the viral load was observed between povidone-iodine, hydrogen peroxide, and cetylpyridinium chloride compared to the no-rinse group at 60 min, indicating their late antiviral potential. Interestingly, a similar statistically significant reduction was also observed in the distilled water control group compared to the no-rinse group at 60 min, proposing mechanical washing of the viral particles through the rinsing procedure. Therefore, results suggest using preprocedural mouth rinses, particularly hydrogen peroxide, as a risk-mitigation step before dental procedures, along with strict adherence to other infection control measures.

Perceptions and attitudes of dental practitioners towards impacts of Covid 19 pandemic on clinical dentistry: a cross-sectional study

Background

The COVID-19 pandemic challenged all healthcare providers including dental practitioners. This cross-sectional study aimed to investigate the dental practitioners’ perceptions and attitudes towards the impacts of COVID-19 on their professional practice, career decision and patient care.

Methods

Data was collected from dental practitioners registered in New South Wales (NSW), Australia using an online survey.

Results and conclusion

Responses received from 206 dental practitioners revealed their perceptions and attitudes towards COVID-19 infection risk, clinical guidelines, and measures adopted to deliver patient care. Majority of participants perceived the risk of infection in dentistry was higher compared with other health professionals. Most dental practices have followed guidelines received from professional associations and adopted multiple measures such as providing hand sanitizer, social distancing, and risk screen, to ensure safe delivery of oral health care. Over 80% of dental practitioners raised concerns on patients’ accessibility to dental care during the pandemic. Despite tele-dentistry was introduced, almost half of the participants did not recognize tele-dentistry as an effective alternative. Moreover, negative impacts of COVID-19 pandemic on dental practitioner’s professional career have been reported, including lower practice safety, reduction in working hours and income. Noteworthy, one quarter of participants even considered changing their practice environment, moving sectors or even leaving their career in dentistry. However, majority of the dental practitioners are willing to stay in their current practice environment and continue their career in dentistry. Our observations demonstrate the systematic disruption to dental practice faced in Australia due to the COVID-19 pandemic. Providing dental practitioners with timely educational training and support is important to minimise negative impacts of the challenges and to optimise dental care.

Impact of COVID-19 on dental practice and anxiety among increased risk group dentists: A cross-sectional study

BACKGROUND: The likelihood of infection with SARS-COV-2 (COVID-19) in the dental office is considered high. OBJECTIVES: Assessing the impact of the COVID-19 on dental practices and anxiety levels in risk group Brazilian dentists. METHODS: A cross-sectional study was performed using an online questionnaire. The data obtained were analyzed using the IBM SPSS 25.0 software (Pearson’s Chi-square association test, multivariate logistic regression, and Poisson multiple regression), with subsequent calculation of the odds ratio at a 95% confidence interval, with a significance level of 5%. RESULTS: Responses of 578 dentists distributed in all regions of Brazil were collected. Most of the dentists were female, with an average age of 35. Of the participants, 23.4% were part of the increased risk group for COVID-19. The professionals who belonged to the increased risk group had a greater chance of not feeling prepared to perform consultations (OR = 1.67) and were not performing any procedures during the pandemic (OR = 2.03). Belonging to the increased risk group did not influence anxiety levels among the dentists. The factors associated with increased anxiety were being female, being younger, working in the southeastern region of the country, being afraid of contracting COVID-19 while working, and being concerned for one’s professional future. CONCLUSIONS: The pandemic has had a negative impact on the professional practice of individuals at risk, but the level of anxiety was like professionals who were not part of the increased risk group for COVID-19.

The Impact of COVID-19 Pandemic on the Psychological Health and Dental Practice of Oral Healthcare Workers: A Scoping Review

This study aims to identify the impact of the COVID-19 pandemic on the psychological health and dental practice of oral health-care workers (OHCWs). The search for relevant literature was carried out online using PubMed, Web of science, and science direct databases from January 2020 to February 2021. Those articles were included that provided complete information about the impact of the COVID-19 pandemic on oral health-care workers during covid-19 and were original articles and reviews. Those articles were excluded from the current study that was not in English Language and involved case reports/book chapters/short communications. Finally, only 8 articles were selected for the scoping review considering that complete information regarding the provision of dental care in the time of COVID-19 was provided. Increased psychological distress (especially those with existing comorbidities) was noted among the OHCWs during this pandemic. They had enough knowledge about COVID-19 and showed concern regarding the future of dentistry. Either complete or partial closure of dental clinics had introduced financial constraints among them. However, the majority of them did not switch their profession. The institutions were not prepared for any such situation and no training was conducted to control the spread of COVID-19 infection. OHCWs are fully aware of the knowledge regarding COVID-19 and showed concerns for dentistry and dental health-care workers during this pandemic. Complete or partial closure of dental clinics has had adverse effects on the future of dentistry, economically as well as psychologically. Institutions need to upgrade and strengthen their systems to cater to any such situation efficiently. Proper counseling sessions should be conducted for the OHCWs to monitor, identify and treat the cases found.

The collapse of infectious disease diagnoses commonly due to communicable respiratory pathogens during the COVID-19 pandemic: A time series and hierarchical clustering analysis

Background

Nonpharmaceutical interventions such as physical distancing and mandatory masking were adopted in many jurisdictions during the coronavirus disease 2019 pandemic to decrease spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We determined the effects of these interventions on incidence of healthcare utilization for other infectious diseases.

Methods

Using a healthcare administrative dataset, we employed an interrupted time series analysis to measure changes in healthcare visits for various infectious diseases across the province of Ontario, Canada, from January 2017 to December 2020. We used a hierarchical clustering algorithm to group diagnoses that demonstrated similar patterns of change through the pandemic months.

Results

We found that visits for infectious diseases commonly caused by communicable respiratory pathogens (eg, acute bronchitis, acute sinusitis) formed distinct clusters from diagnoses that often originate from pathogens derived from the patient’s own flora (eg, urinary tract infection, cellulitis). Moreover, infectious diagnoses commonly arising from communicable respiratory pathogens (hierarchical cluster 1: highly impacted diagnoses) were significantly decreased, with a rate ratio (RR) of 0.35 (95% confidence interval [CI], .30–.40; P < .001) after the introduction of public health interventions in April–December 2020, whereas infections typically arising from the patient’s own flora (hierarchical cluster 3: minimally impacted diagnoses) did not demonstrate a sustained change in incidence (RR, 0.95 [95% CI, .90–1.01]; P = .085).

Conclusions

Public health measures to curtail the incidence of SARS-CoV-2 were widely effective against other communicable respiratory infectious diseases with similar modes of transmission but had little effect on infectious diseases not strongly dependent on person-to-person transmission.

An Assessment of Various Challenges Perceived by Dental Students amidst the COVID-19 Pandemic: A Digital Questionnaire Study

The objective of our study was to evaluate dental students’ perception of the challenges faced during the COVID-19 pandemic related to their clinical work, education, performance, online examinations, psychological health, and teamwork. A validated online questionnaire consisting of closed ended questions was sent to all the undergraduate dental students at our institute. Data were collected and analyzed statistically using a chi-square test to compare responses of male with female and junior with senior students. A total of 317 undergraduate dental students (N = 317) participated in this cross-sectional study. The most common challenges perceived by the participants were related to their exam duration (77.3%), patient availability (66.9%), difficulty in understanding online lectures (58.4%), and a fear of losing grades (57.4%). Participants reported that the COVID-19 pandemic affected their performance in the courses (75.4%), teamwork (72.2%), educational aspects (67.5%), and psychological health (51.1%). A significantly greater proportion of female students reported the adverse effects of COVID-19 on their psychological health than male students (p = 0.031). Senior students perceived the negative impact of COVID-19 on teamwork significantly more than the junior students (p = 0.004). The majority of students reported challenges during the COVID-19 pandemic. Female students and senior students perceived more challenges than their counterparts. Future studies from other institutes of this region are recommended to establish a clearer picture of COVID-19 related challenges faced by dental students.

Trends in dental insurance claims in the United States before and during the SARS-CoV-2 pandemic in 2020

OBJECTIVES

The SARS-CoV-2 pandemic disrupted health care services. Previous reports estimated reductions in demand and supply of dental care services, but actual changes have not been reported. The present report depicts a perspective of trends in claims from private dental practice in the United States during 2019 and 2020.

METHODS

Private dental insurance paid claims data from a data warehouse (encompassing 66+ carriers in the United States) were obtained for children and adults (treatments identified by their American Dental Association Code of Dental Procedures and Nomenclature [CDT]), encompassing a 5% random sample of all records between January 2019 and December 2020. A market-based treatment classification placed CDT codes into one of four categories based on the likelihood of being associated with urgent/emergency care.

RESULTS

Claims for 3.8 million patients constituted the 5% random sample for analyses. Substantial drops in the provision of treatment items were quantified for a large segment of private dental insurance plans at a national level, showing differential impacts in dental care categories.

CONCLUSIONS

Week-by-week, detailed descriptions of demand/availability changes in dental care throughout the first year of the 2020 SARS-CoV-2 pandemic were obtained through contrasting perspectives in 2019. Provision of dental care and associated impacts fluctuated over time subject to treatment urgency, but also modified as the weeks/months of dental office lockdowns ebbed in and out of the dental market.

Impact of COVID-19 pandemic on the practice of pediatric dentistry in the United Arab Emirates: a cross-sectional survey

Background

The aim of this study was to assess the impact of COVID-19 epidemic circumstances on the practice of pediatric dentistry in the United Arab Emirates.

Methods

An online questionnaire was distributed among members of Emirates Club of Pediatric Dentistry. The questionnaire was divided into three sections: (1) dentists’ demographic characteristics, (2) general knowledge and attitude toward COVID-19, (3) practice of pediatric dentistry during COVID-19 pandemic.

Results

Female pediatric dentists were double the males and the age distribution tended towards the younger age group. Most of the participants had a satisfactory level of knowledge about COVID-19 and 100% of them obtained this knowledge from the health authorities. Around one third of the participants were not confident of their ability to work safely during the epidemic. There was a marked diversity between pediatric dentists regarding the priority services to be delivered to children during the COVID-19 peak.

Conclusion

A majority of pediatric dentists in the UAE are well informed regarding COVID-19 and its prevention. The economic impact of the epidemic has disrupted pediatric dentists’ willingness to prioritize certain dental services over others. This is related to safety concerns, financial urge, and patient needs.

Evaluation of the economic impact of COVID-19 on Brazilian private dental clinics: A cross-sectional study

BACKGROUND

The changes in dental care in the face of the COVID-19 pandemic resulted in the need for greater financial investment by dentists in biosafety measures and increase in the costs of dental consultations.

OBJECTIVE

To evaluate the economic impact of the COVID-19 pandemic on dental practices in private clinics in Brazil.

METHODS

A cross-sectional study was carried out, using an online questionnaire indexed in Google Forms, and distributed among dentists. The data obtained were analyzed using the IBM SPSS 25.0 software, evaluating the factors associated with strong or very strong impact on the participants' income and the factors that motivated the dentists to look for a credit line. Multiple logistic regression models were constructed to identify the associated factors. Variables with p <  0.05 were considered statistically significant.

RESULTS

Most participants were female, with a median age of 35 years. Dentists who are most concerned about their professional future (OR = 3.134; 95% CI: 1.804-5.445), who have longer office hours (OR = 2.056; 95% CI: 1.198-3.529), who had the greatest impact on the flow of patients (OR = 16.358; 95% CI: 9.408-28.443) and in need of investing in infrastructure (OR = 1.756; 95% CI: 1.014-3.041), had the greatest impact on monthly earnings.

CONCLUSIONS

The pandemic and the new biosafety recommendations for care during this period had a negative impact on the income of Brazilian dental offices and increased the chance of seeking credit to alleviate the financial deficit.

Intraoral scanning reduces procedure time and improves patient comfort in fixed prosthodontics and implant dentistry: a systematic review

OBJECTIVES

The primary aim of this systematic review was to evaluate whether intraoral scanning (IOS) is able to reduce working time and improve patient-reported outcome measures (PROMs) compared to conventional impression (CI) techniques, taking into account the size of the scanned area. The secondary aim was to verify the effectiveness of IOS procedures based on available prosthodontic outcomes.

MATERIALS AND METHODS

Electronic and manual literature searches were performed to collect evidence concerning the outcomes of IOS and CI performed during the treatment of partially and complete edentulous patients for tooth- or implant-supported restorations. Qualitative analysis was conducted to evaluate the time efficiency and PROMs produced by the two different techniques. Clinical prosthodontic outcomes were analyzed among the included studies when available.

RESULTS

Seventeen studies (9 randomized controlled trials and 8 prospective clinical studies) were selected for qualitative synthesis. The 17 included studies provided data from 430 IOS and 370 CI performed in 437 patients. A total of 7 different IOS systems and their various updated versions were used for digital impressions. The results demonstrated that IOS was overall faster than CI independent of whether quadrant or complete-arch scanning was utilized, regardless of the nature of the restoration (tooth or implant supported). IOS was generally preferred over CI regardless of the size of the scanned area and nature of the restoration (tooth- or implant-supported). Similar prosthodontic outcomes were reported for workflows implementing CI and IOS.

CONCLUSIONS

Within the limitations of this systematic review, IOS is faster than CI, independent of whether a quadrant or complete arch scan is conducted. IOS can improve the patient experience measured by overall preference and comfort and is able to provide reliable prosthodontic outcomes.

CLINICAL RELEVANCE

Reduced procedure working time associated with the use of IOS can improve clinical efficiency and the patient experience during impression procedures. Patient-reported outcome measures (PROMs) are an essential component of evidence-based dental practice as they allow the evaluation of therapeutic modalities from the perspective of the patient. IOS is generally preferred by patients over conventional impressions.

Motivation and job satisfaction among medical and dental college faculty in Pakistan amid the COVID-19 outbreak

BACKGROUND

The novel coronavirus (COVID-19) has affected economies all over the world. The ability of an organization to grow is heavily influenced by job satisfaction and employee motivation.

OBJECTIVE

This study examines the factors affecting employee motivation and job satisfaction among medical and dental college faculty members in Pakistan, both in the private and public sector, during the COVID-19 pandemic.

METHODS

Medical and dental college faculty in Pakistan comprised the sample for this multi-centric cross-sectional study. A questionnaire, which was modified from an existing study, was distributed electronically. A student's independent t-test was applied to compare the mean scores of the responses from public and private sector employees.

RESULTS

Of the 466 total respondents, 55 %were female and 45 %male. Public sector faculty reported receiving adequate resources and preferred online teaching. Both public and private sector faculty reported being satisfied with regular workshops and training. Private sector employees demonstrated more satisfaction with workplace safety measures. Public sector faculty highlighted the positive influence of job security and timely salary payments on productivity.

CONCLUSION

Faculty members from both the public and private sector find working from home to be easier and better for handling one's workload. Public sector faculty noted job security, timely salary payments, and an individual's sense of achievement as sources of motivation. Private institutes are more lacking in ensuring their faculty feel content and satisfied. Measures should be undertaken to improve the level of motivation felt by faculty members, especially in the private sector.

The Importance of Atmospheric Microbial Contamination Control in Dental Offices: Raised Awareness Caused by the SARS-CoV-2 Pandemic

Background: In the context of the Sars-CoV-2 pandemic that started in 2020, more attention is being paid to the air quality in medical offices. The medical, economic and social implications of this crisis are unprecedented. Dental offices, particularly, were significantly affected by this pandemic due to the high exposure of dental workers, limited availability of personal protective equipment (PPE) and serious financial problems. Methods: Four different procedures were compared regarding their effectiveness in air contamination reduction, both from a biological point of view and from a management point of view: Fogging, Ultraviolet C (UVC) lamps, UVC air circulation units and natural ventilation. A total of 56 Petri dishes were used to evaluate air contamination. Results: All four procedures offered good results but the decontamination time and overall effect varied depending on the chosen method. Fogging was the only method that managed to remove all the identifiable pathogens. Conclusions: Fogging proved to be superior from a medical point of view, while the UVC air circulation unit proved to be more efficient from a management point of view.

Impact of the coronavirus disease 2019 pandemic on periodontal practice: A questionnaire survey

Aim

This cross‐sectional study sought to investigate the factors possibly related to the impact caused by the coronavirus disease 2019 pandemic in the practice of periodontists, in two countries.

Materials and methods

A total of 254 periodontists with active periodontics licensing in Brazil and the United States participated in the survey. Data were collected through an online questionnaire and the dependent variable was the perceived impact of the pandemic on periodontists' practice routines. Odds ratios were assessed by logistic regression analysis.

Results

Periodontists in private practice were 83% less likely to report a significant impact of the pandemic on their clinical routine as compared with professionals who work in the public sector or in academic institutions (CI 95%: 0.05–0.47). The financial impact of the pandemic was significantly associated with a perceived severe impact of the pandemic on their routines (OR: 1.36; CI 95%: 1.16–1.61). Professionals who have enhanced their hand‐washing routine were more likely to report a significant impact of the pandemic by 3.41 times (CI 95%: 1.28–9.04) relative to those who have not altered their hand‐washing protocols.

Conclusion

The pandemic is associated with a negative impact on the practice of periodontists, especially those working in public sectors and academic institutions.

Dental and Medical Students' Knowledge and Attitude toward COVID-19: A Cross-Sectional Study from Pakistan

Objective  The aims of this study were to investigate the awareness, knowledge, and attitudes of Pakistani medical and dental undergraduate students toward COVID-19 during the surge of its outbreak.

Materials and Methods  The multicentered, cross-sectional study was carried out nationwide among undergraduate medical and dental students. A convenience sampling technique was used. A self-developed online questionnaire was pretested to be completed by the participants. It was distributed using social media. The survey was comprised of questions related to demographics, health status, general hygiene perception, understanding, and the learning attitudes of the students. Comparisons of the knowledge scores and the attitude responses with the demographic information were done using the independent t -test, one-way ANOVA, and Chi-square, as appropriate.

Results  Of the 937 total respondents, 353 (38%) were males and 582 (62%) were females; two students did not mark their gender. Of these, 680 (73%) were dental students and 257 (27%) were medical students. The mean knowledge score of the female dental students (5.15 ± 1.08) was significantly higher than that of the male students (4.87 ± 1.09). Overall, the mean knowledge score was statistically higher among the medical students in comparison to the dental students (5.21 ± 1.15, 5.05 ± 1.09; p = 0.054), respectively.

Conclusion  The medical and dental students were both aware of the importance of the use of a mask. The medical students had a greater awareness regarding the mode of transmission, symptoms, and origin of COVID-19. However, the dental students showed better understanding of the use of surgical masks and the correct protocol for hand washing. Social media was considered the main source for COVID-19 related information.
