COVID-19 infection among health care workers in a tertiary care teaching hospital in Kerala - India.

UNLABELLED: Health care workers are at the frontline for management and containment of COVID-19 infection which has put them at additional risk of the disease. Infection and subsequent quarantine of contacts among HCW may produce considerable strain on the health care system. It is essential that we study the modes by which HCW may get infected in the work environment.

METHODS

All HCW testing positive for SARS COV 2 from 1st March 2020 to 31st Jan 2021 were included in the study. Data regarding possible source of infection, details of symptoms along with demographic details were collected.

RESULTS

A total of 390 health-care workers tested positive for SARS CoV-2 in the institution. The mean age of affected health-care workers was 32.82 (±10.6) years (range 20-65 years), and 61.3% were female 33% of the positive HCW were doctors and 19.5% nurses. 29% of the infections occurred during patient care of which majority were from the non-COVID areas of the hospital. Interactions with infected colleagues constituted 27.4% of the infections. Symptomatics constituted 67% and the predominant symptoms included Fever, myalgia and severe headache. 57.2% of those followed up reported persistence of symptoms, commonly fatigue (53%), dyspnea on exertion (48%) and myalgia (18%).

CONCLUSION AND RECOMMENDATION: Infection control practices in non-COVID areas of the hospital needs to be stepped up. Adherence to masking and personal protection during clinical interactions and with colleagues needs to be maintained. Physical distancing at workplace and during mealtimes needs to be ensured by the system.
