Institutional quarantine centres as a strategy in control of COVID-19 outbreak: An evolving model from Kerala, India

BACKGROUND: Institutional quarantine centres were set up in all districts in Kerala as a novel strategy in the fight against novel COVID-19 virus. These were meant for returnees from affected areas, for whom home quarantine was not possible due to lack of facilities. This research aims to evaluate facilities and services of Institutional quarantine centres in Thiruvananthapuram district, Kerala state and to study profile of persons under quarantine in these centres. METHODS: A cross-sectional study was conducted to evaluate institutional quarantine centres established in Thiruvananthapuram district of Kerala in April 2020. Evaluation was done using a checklist based on standard operating procedures for functioning of centres issued by Health department. Inspection of facilities and registers was done. Details of a subset of inmates were collected by telephonic interviews using a semi-structured questionnaire. RESULTS: Two (0.41%) inmates in the centre turned positive on testing while in quarantine. Both of them were foreign returnees and were asymptomatic. There was not a single case of transmission of infection between inmates or to staff and volunteers. The adherence to infection control practices was satisfactory in all centres. One third of inmates were from listed highly affected countries and were mandatorily quarantined. CONCLUSION: Institutional quarantine centres were functioning effectively to provide quarantine facilities for high-risk individuals and thereby controlling the spread of COVID-19. Selection of facilities, staffing pattern and day to day functioning of these centres is a model which can be replicated at other COVID-19 affected areas.
