Abstract

Background: This study presents the various variables of the first cluster of COVID-19 was identified in the Union Territory of Dadra and Nagar Haveli and Daman and Diu, India.

Methods: The investigation design combined active case findings, contact tracing, and containment policy around each confirmed case. The various epidemiological parameters were counted with the verbal autopsy of confirmed cases and possible contacts.

Results: It was a small-scale cluster that started with an imported case. In this cluster, a total of 18 infected persons, 243 high-risk contact, and 105 low-risk contacts were identified. The entire confirmed cases were linked to each other within a single chain of transmission, therefore; Airborne, droplet, and hand-to-hand transmissions were suspected.

Conclusions: The results of the present study were suggested that early detection, active surveillance, testing of suspected cases, isolation of cases and quarantine of contacts are the key objectives to contain the COVID-19 disease cluster. But we have to keep in concern what are variables affect about different type of the objectives of the cluster containment at the grassroots level.
