Nature and Magnitude of COVID-19 First Wave in Tamil Nadu, India
The first case of COVID-19 Tamil Nadu was confirmed on 7th March 2020 in Chennai after an international travel from Muscat. The specific objectives of the study were to analyze the trends in COVID 19 in Tamil Nadu from March 2020 to January 2021 and examine the pattern of it sex-wise among the age groups. The risk of COVID-19 was accessed with the computation of positive test rate, prevalence rate and fatality rate. The prevalence rates were highest in August, with a slight downfall in September 2020 in the state. The positivity test rate was high in June and July. Then it started declining and has been one percent in January. About 83 percent of the occurrence of the virus was among the middle age group, 13 percent among the elderly and four percent among the children. Intensifying immunity boosters, personal and public hygiene, vaccination on a large scale probably would contain the second wave and prohibit the third wave for the survival of humanity.
