COVID-19 reinfection in Afghanistan: A descriptive analysis of data from DHIS2, 2022

Abstract

Background: Despite millions of COVID-19 infections worldwide since the beginning of the pandemic, relatively few confirmed cases of COVID-19 reinfection have been reported. In Afghanistan, COVID-19 undetected cases are more than detected cases. This study aims to describe the burden of COVID-19 reinfection cases in Afghanistan, along with the epidemiological and demographical patterns. Methods: A descriptive study of national-wide secondary data on COVID-19 reinfection cases was carried out from January to June 2022. Data were extracted from the District Health Information Software 2 (DHIS2) and managed and analyzed using Microsoft Excel and Epi Info V.7.2.1. Results: In 2022, 79 reinfection cases of COVID-19 were reported, with males being more affected than females. The mean age of re-infected patients was 39, with most from Wardak province. Most cases occurred within six months after the primary infection. Cough was more prevalent among reinfected cases. Only 26 patients had taken two doses of the vaccine, while 44 (55.70%) had not received it. Out of all cases, 44 (55.70%) were recovered and 5 (6.85%) died. Conclusion: The COVID-19 reinfection rate is very low in Afghanistan, which was common in males since other cases might be unreported. Coughing was more common among reinfection patients. Relying on the results, vaccination and awareness-raising may play a protective role in reinfection; hence, enhancement of vaccination and taking preventive measures are recommended to prevent further reinfection.
