Abstract


Background: Health-care workers (HCWs) may get infected by direct or indirect contact with infected patients or other HCWs or from the community as well, depending on the phase through which pandemic progresses. Knowledge about the disease transmission dynamics as the pandemic advances is a need so that appropriate monitoring, prevention and control measures for HCWs can be implemented at local level. The main objective of this study was quadmester-wise comparison of disease transmission dynamics of COVID-19 among HCWs in Kannur district.

Methods: A cross-sectional study was carried out among HCWs reported positive for SARS-CoV-2 in Kannur district, Kerala. COVID-19 positive HCWs reported in the district were consolidated and contacted over phone and details were collected using a semi-structured questionnaire. Data were entered into microsoft excel and analysed using statistical package for social sciences (SPSS) trial version. Chi-square test was used to compare differences observed in the two groups and binary logistic regression was done to pick out the significant predictors of variability in disease transmission among the two groups.

Results: Total respondents in the first and second quadmester were 243 and 1665, respectively. Factors like gender, clinical features, source of infection, family as source and type of duty taken were found to be statistically significant for the disease transmission dynamics among HCWs.

Conclusions: As the pandemic advances, irrespective of the type of work place, self-reporting and regular testing of HCWs will help to check HCWs from getting infected and spreading the disease.
