a public health threat worldwide, particularly in densely populated countries. Geographic information system (GIS) can be used to map the geographical distribution of disease, trends in community spread of disease and to identify significant hotspots and cluster zones of COVID-19. The aim of the study is to analyse the spatial extent of disease transmission through mapping and preparation of graphs at ward level and to prepare a web mapping application to get the COVID-19 information from July 2020 to February 2021 related to 100 wards in Trivandrum Corporation in Kerala.
1.1 OBJECTIVE
Key Words: COVID-19; GIS; Trivandrum Corporation
The objective of the study is to analyse the extent of community spread of COVID-19 for Trivandrum corporation by the creation of map showing the ward wise COVID-19 cases for Trivandrum corporation from July 2020 to February 2021 and to find any possible relationship between COVID-19 cases and population density. Then to create a web mapping application to obtain the COVID-19 related information in Trivandrum Corporation.

The novel coronavirus disease 2019 (COVID-19) infection, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first emerged in December of 2019 in Wuhan city, China. The first case of the COVID-19 pandemic in Kerala was confirmed in Thrissur on 30 January 2020, which was the first case reported in India. As of 11 January, there have been 29,14,557 confirmed cases with 28,08,062 (96.13%) recoveries and 13,197 (0.45%) deaths in the state. A high number of cases was reported on March in India, Kerala had reduced the rate of increase of new cases to less than 0.25% per day by April 30. However, in mid-May, there was an increase in new confirmed cases, following the return of Keralites from other countries and other Indian states. In July, a large local group of cases was identified at the Kumarichantha fish market in Thiruvananthapuram. There has been a third surge in cases post Onam and a high number of new cases was reported in late- October in Malappuram, Kozhikode, Ernakulam and Thrissur districts. The state has the lowest case fatality rate compared to the confirmed cases. The largest single-day spike of 42,464 cases was reported on May 6, 2021 in Kerala. As of October 2020, more than 90% of known cases were due to community spread. Kerala is presently at 3rd position in daily number of COVID19 cases state wise in India. Vaccines like Covishield and Covaxin have been introduced in Kerala which is found to be effective. In Kerala, 30.01% of people, ie, 1,06,49,645 people have taken the vaccination of which 30,99,039 have taken both doses of vaccine. Early detection of the virus and
