COVID 19 infection clinical features in pediatric patients in Southwestern Iran: a cross-sectional, multi-center study

With the SARS-CoV-2 pandemic, the impact of recent coronavirus, especially in children, cannot be ignored. In this study, we evaluated the SARS-CoV-2 infection rates and associated features in children less than 18 years of age in "Fars" and "Kohgiluyeh and Boyer Ahmad", provinces, Iran. 5943 children who were suspected cases to SARS-CoV-2 infection were enrolled in this study. Demographic and clinical data of SARS-CoV-2 patients were collected from 16 February 2020 to 20 June 2021. Underlying conditions were considered in this study as well. Among 5943 patients suspected COVID 19 cases, 13.51% were confirmed by real-time PCR assay. The female/male ratio was 1:1.3 with a mean age of 5.71 years. 11.2% of confirmed patients were transferred and admitted in Pediatric ICU. COVID 19 was significantly higher in children with malignancy and diabetes rather than those with other underlying diseases. Children of all ages were susceptible to COVID 19, and there is no significant difference between both sexes. Most of the COVID 19 cases were in 10-18 years old group. Among a number of children with different underlying diseases, children with malignancy had the highest rate of SARS-CoV-2 infection, followed by those with diabetes.

Comparing clinical presentation, viremia, and immunological factors at various severity presentations in hospitalized children affected by COVID-19: A cross-sectional study

Background and Aims

Although SARS-CoV-2 infection usually leads to mild COVID-19 in children, sometimes it causes serious complications, especially in those with underlying diseases. Several factors have been identified in determining disease severity in adults, and limited studies have been conducted in children. The prognostic implications of SARS-CoV-2 RNaemia as an important factor in determining disease severity in children are not well understood.

Methods

In this study, we aimed to prospectively assess the relationship between disease severity and immunological factors and viremia in 47 COVID-19 hospitalized children. In this research, 76.5% of children experienced mild and moderate COVID-19, while 23.5% experienced severe and critical forms of the disease.

Results

The presence of underlying diseases in different groups of pediatric patients differed significantly from each other. On the other hand, clinical symptoms such as vomiting and chest pain as well as laboratory parameters including erythrocyte sedimentation rate were significantly different in different groups of patients. Viremia was seen in only two children, and this had no significant relationship with the severity of COVID-19.

Conclusion

In conclusion, our data confirmed that COVID-19 severity differed in SARS-CoV-2 infected children. Some clinical presentation and lab data parameters were different in various presentation of patients. Viremia was not associated with severity in our study.

Effect of COVID‐19 on healthcare workers' morbidity and mortality compared to the general population in Kohgiluyeh and Boyer‐Ahmad Province, Iran

During the Covid‐19 pandemic, the adverse effects of recent coronaviruses on healthcare professionals cannot be ignored. This study compared the admission rates due to Covid‐19 and characteristics of hospitalized healthcare workers with the general population of Kohgiluyeh and Boyer‐Ahmad (K.B) province. 18546 hospitalized patients infected with Covid‐19 in hospitals in four cities of K.B province were enrolled in this study; of them, 236 (1.27%) patients were healthcare workers. Demographic and clinical data of hospitalized cases due to Covid‐19 infection were collected from August 2020 to September 2021. The underlying diseases were also considered in this study. According to our findings, 55.5% of the hospitalized healthcare workers were male, and 44.5% were female; their mean age was 41.41 years. However, in the general population, hospitalization rates were higher for women than for men (51.2% and 48.8%, respectively). Although the SARS‐CoV‐2 infectivity rate was higher in healthcare workers compared to the general population (68.6% vs. 56.1%), the mortality rate was significantly lower in them (1.7% vs. 3.8%). Fever, cough, Acute Respiratory Distress Syndrome, headache, and myalgia were the most prevalent symptoms in both groups. Among the cases examined in this study, inpatient ones aged 30–40 years and the general population aged over 60 seemed to be more likely to be hospitalized for Covid‐19. The hospitalization rate of healthcare workers during the pandemic follows the same pattern as the general population, but since the start of vaccination, this rate has decreased among healthcare workers compared to the general population of KB province.
