Incidence and risk factors of SARS-CoV-2 infection among workers in a public health laboratory in Tunisia

The aim of this study was to measure the extent of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among workers at the Institut Pasteur de Tunis (IPT), a public health laboratory involved in the management of the COVID-19 pandemic in Tunisia, and to identify risk factors for infection in this occupational setting. A cross-sectional survey was conducted on IPT workers not vaccinated against coronavirus disease 2019 (COVID-19). Participants completed a questionnaire that included a history of reverse transcription-polymerase chain reaction (RT-PCR)-confirmed SARS-CoV-2 infection. Immunoglobulin G antibodies against the receptor-binding domain of the spike antigen (anti-S-RBD IgG) and the nucleocapsid protein (anti-N IgG) of the SARS-CoV-2 virus were detected by enzyme-linked immunoassay (ELISA). A multivariate analysis was used to identify factors significantly associated with SARS-CoV-2 infection. A total of 428 workers were enrolled in the study. The prevalence of anti-S-RBD and/or anti-N IgG antibodies was 32.9% [28.7-37.4]. The cumulative incidence of SARS-CoV-2 infection (positive serology and/or previous positive RT-PCR test) was 40.0% [35.5-44.9], while the proportion with asymptomatic infection was 32.9%. One-third of the participants with RT-PCR-confirmed infection tested seronegative more than 90 days postinfection. Participants aged over 40 and laborers were more susceptible to infection (adjusted OR [AOR] = 1.65 [1.08-2.51] and AOR = 2.67 [1.45-4.89], respectively), while tobacco smokers had a lower risk of infection (AOR = 0.54 [0.29-0.97]). The SARS-CoV-2 infection rate among IPT workers was not significantly different from that detected concurrently in the general population. Hence, the professional activities conducted in this public health laboratory did not generate additional risk to that incurred outside the institute in day-to-day activities.

Adherence with COVID-19 Preventive Measures and Associated Factors Among Residents of Dirashe District, Southern Ethiopia

INTRODUCTION

COVID-19 is one of the huge general wellbeing crisis for the planet. Since its first recognition, over 90.2 and 1.9 million people are infected and dead, respectively. Although it is not easily available for low-income countries, after many trials vaccination is initiated by some industrialized nations. However, still now there is no effective treatment for the infection. Henceforth, adherence with COVID-19 preventive and control measures is the only option to stop its spread and minimize its disastrous impact, especially, in developing nations like Ethiopia. Knowledge and behavior change are pillars to engage with preventive measures. Thus, the motivation behind this study was to assess communities' adherence with COVID-19 preventive measures and its associated factors among inhabitants of Dirashe district, Southern Ethiopia.

MATERIALS AND METHODS

A cross-sectional study was directed among 648 inhabitants in Dirashe district from June 20 to July 5, 2020. A multistage sampling technique was applied to select the participants. A pretested, validated and reliable interviewer-administered survey tool comprising the socio-demographic characteristics, knowledge (α = 0.78), and adherence with COVID-19 preventive measures (α = 0.73) was used. The data were assorted electronically using Open Data Kit (ODK) collect version 1.17.2 android application and exported to Stata version 15.0 for analysis. Adjusted odds ratio (aOR) with 95% CI was used to identify variables associated with the community's adherence with COVID-19 preventive measures.

RESULTS

An aggregate of 644 inhabitants were participated in this study; of them, only 12.3% [95% confidence interval (CI): 9.8, 15.1] adhered to the recommended COVID-19 preventive measures. Likewise, 63.51% [95% CI: 59.7, 67.2] and 54.5% [95% CI: 50.6, 58.4] of the participants had good knowledge and favorable attitude towards COVID-19 preventive measures, respectively. Urban residence [aOR: 9.74, 95% CI: 4.72, 20.10], favorable attitude [aOR: 1.97, 95% CI: 1.05, 3.68] and concerned about COVID-19-related stigma [aOR: 2.43, 95% CI: 1.02, 5.79] were independently associated with communities adherence with COVID-19 preventive measures.

CONCLUSION

In general, communities' adherence to the recommended COVID-19 preventive measures was very low in the area. Addressing underprivileged population groups, disseminating teaching aids in local languages, behavioral change communications, and law enforcement is imperative to strengthen COVID-19 prevention practice.
