Trop Med Infect Dis 2022; 7:tropicalmed7100257. [PMID: 36287998 PMCID: PMC9609570 DOI: 10.3390/tropicalmed7100257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 08/26/2022] [Accepted: 09/07/2022] [Indexed: 11/16/2022] Open
Abstract
In this paper, we provide an overview of how spatial video data collection enriched with contextual mapping can be used as a universal tool to investigate sub-neighborhood scale health risks, including cholera, in challenging environments. To illustrate the method’s flexibility, we consider the life cycle of the Mujoga relief camp set up after the Nyiragongo volcanic eruption in the Democratic Republic of Congo on 22 May 2021. More specifically we investigate how these methods have captured the deteriorating conditions in a camp which is also experiencing lab-confirmed cholera cases. Spatial video data are collected every month from June 2021 to March 2022. These coordinate-tagged images are used to make monthly camp maps, which are then returned to the field teams for added contextual insights. At the same time, a zoom-based geonarrative is used to discuss the camp’s changes, including the cessation of free water supplies and the visible deterioration of toilet facilities. The paper concludes by highlighting the next data science advances to be made with SV mapping, including machine learning to automatically identify and map risks, and how these are already being applied in Mujoga.

Abstract
Mexico's violence related to organized crime activity has grown to epidemic levels in the last 12 years. We interviewed 22 Mexican health care providers from five states to examine how violence impacts health care services and health. We transcribed and analyzed semi-structured interviews using framework analysis. Our findings describe the ways in which community violence in Mexico permeates health care services, impacting health care providers, and the health of patients. We developed a model to reflect our main themes that illustrate how violence permeates health care services over geographic space and time. We identified three thematic categories: (a) the impact of violence on health care facilities and service provision, (b) the impact of violence on providers, and (c) the impact of violence on the health of the community. Our model articulates a dynamic process of the spread and permeation of violence. Prior literature focuses on the impact of violence as an occupational hazard and the effect of war or civil conflict on health care services. We extend this literature by documenting the impacts of widespread violence on Mexican health care services and providers. We discuss how violence impacts services, providers, and health in a country that is not officially at war. We compare our findings to previous literature on occupational violence in health professions and the impacts on health services in official war zones. Finally, we highlight the implications for health care practice and policy. We suggest that violence should be considered throughout the care continuum in Mexico and make the case for violence as a structural contributor to health and health disparities in Mexico. We suggest additional research on this under-investigated topic.

Prevention and control of mosquito-borne arboviral diseases: lessons learned from a school-based intervention in Brazil (Zikamob). BMC Public Health 2022; 22:255. [PMID: 35135522 PMCID: PMC8822808 DOI: 10.1186/s12889-022-12554-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 01/11/2022] [Indexed: 11/10/2022] Open
Abstract
Background Since the 1980s, when dengue was reintroduced in Brazil, outbreaks and epidemics caused by different arbovirus strains transmitted by vector mosquitoes such as Aedes aegypti have been an annual occurrence. The aim of this study was to evaluate the behavioural change of high school students and teachers who participated in an educational intervention for the prevention and vector control of arboviral diseases. Methods In this school-based intervention, a self-reported questionnaire was used in a pre-post intervention methodology to assess environmental risk factors, sociodemographic variables and to measure attitudes and behaviours. In all, 883 high school students and teachers from the city of Campina Grande, in the state of Paraíba, northeastern Brazil, participated. The e-health intervention consisted of a competition between schools to comply with preventive actions via content production for social networks, and the monitoring was performed over a period of three months through the ZikaMob software developed by the researchers. Results Out of the 883 survey participants, 690 were students ranging in age from 14 to 41 years, with an average of 17 ± 2 years; and 193 were teachers from 22 to 64 years old, averaging 38 ± 9 years. The analysis of the data shows that significant differences in most of the target behaviours were apparent after the intervention, with an increase of about 10% in the performance of inspection actions; a 7% greater separation of recyclables and a 40% increase in the screening of windows among students. Students showed lower fear of, and a lower self-perception of the risk of, acquiring arboviruses than teachers on average. Conclusions ZikaMob is an innovative strategy with the potential to be replicated in any location that has an internet network and can involve an unlimited number of participants.

Abstract
OBJECTIVES We analyze the degree to which community violence in Mexico, largely due to organized crime violence, affects health care service utilization. METHODS This study exploits temporal and geographic variation in monthly county-level homicide rates, matching outpatient service utilization from individual longitudinal measures. Sensitivity analyses test for an age specific concentration of violence, respiratory conditions that are likely unrelated to violence, insurance status and health center availability per capita. We test for distributional responses to violence by urban and rural localities. RESULTS The likelihood of service utilization increases by 5.2% with each additional homicide per 100,000. When we include self-reported health conditions in the model, our main coefficient remains significant at 4.5%. We find no added effect to our results from interaction terms for age specific concentration of violence, respiratory conditions, insurance status, or health center availability. A substantial increase of 11.7% in the likelihood of service utilization occurs in localities with > = 100,000 inhabitants, suggesting that service utilization is sensitive to the location of violence. CONCLUSIONS Results highlight the relationship between and increase in violence at the local level and an increase in health care service utilization. This study is among the first to examine this relationship empirically in Mexico. Future research is needed to shed more light on this relationship and its mechanisms.

Abstract
Tuberculosis (TB) contact investigation facilitates earlier TB diagnosis and initiation of preventive therapy, but little data exist about the quality of its implementation. We conducted a retrospective cohort study to evaluate processes of TB contact investigation for index TB patients diagnosed in Cali, Colombia, in 2017, including dropout at each stage and overall yield. We constructed multivariable models to identify predictors of completing 1) the baseline household visit and 2) a follow-up clinic visit for TB evaluation among referred contacts. Sixty-eight percent (759/1,120) of registered TB patients were eligible for contact investigation; 77% (582/759) received a household visit. Odds of completing a household visit were significantly lower among men (adjusted odds ratio [aOR]: 0.6; 95% CI: 0.4-0.9; P = 0.009) and patients living in Cali's western zone (aOR: 0.5; 95% CI: 0.3-0.8; P = 0.008). Among 1880 screened contacts, 31% (n = 582) met the criteria for clinic referral, 47% (n = 271) completed a clinic visit, and 85% (231/271) completed testing. After adjusting for clustering by index patient, odds of completing referral were higher among contacts with cough (aOR: 22; 95% CI: 7.1-66; P < 0.001) and contacts living in the western zone (aOR: 4.1; 95% CI: 1.2-15; P = 0.03). The cumulative probability of a symptomatic contact from an eligible household completing TB evaluation was only 28%. The yield of active TB patients among contacts was only 0.3% (5/1880). Only 16% (17/103) of children aged < 5 years were included, and none of the eight persons were living with HIV-initiated preventive therapy. Routine monitoring of process indicators may facilitate quality improvement to close gaps in contact tracing and increase yield.

Abstract
In 2014, the chikungunya virus reached Colombia for the first time, resulting in a nationwide epidemic. The objective of this study was to describe the demographics and clinical characteristics of suspected chikungunya cases. Chikungunya infection was confirmed by enzyme-linked immunosorbent assay and 548 patients where included in the study. Of these patients, 295 were positive for antibodies against chikungunya (53.8%), and 27.6% (151/295) were symptomatic for chikungunya infection, with a symptomatic:asymptomatic ratio of 1.04:1. Factors associated with infection included low income and low socio-economic strata (odds ratio [OR]: 1.8; 95% confidence interval [CI]: 1.0-3.2, p = 0.003 and OR: 2.1; CI: 1.3-3.4, p = 0.002, respectively). Confirmed symptomatic cases were associated with symmetric arthritis (OR: 11.7; CI: 6.0-23.0, p < 0.001) of ankles (OR: 8.5; CI: 3.5-20.9, p < 0.001), hands (OR: 8.5; CI: 3.5-20.9, p < 0.001), feet (OR: 6.5; CI: 2.8-15.3, p < 0.001), and wrists (OR: 17.3; CI: 2.3-130.5, p < 0.001). Our study showed that poverty is associated with chikungunya infection. Public health strategies to prevent and control chikungunya should focus on poorer communities that are more vulnerable to infection. The rate of asymptomatic infections among confirmed cases was 48.8%. However, those with symptoms displayed a characteristic rheumatic clinical picture, which could help differentiate chikungunya infection from other endemic viral diseases.
