There has been research in Tamil Nadu and Andhra regarding the spread of coronavirus. The transmission of COVID-19 in India has been inspired chiefly by superspreaders or a small percentage of infected people, according to the largest contact tracing study in the country which also shows that children are key to the scope of the novel coronavirus. The researchers, including those from the Government of Tamil Nadu, and Andhra Pradesh, discovered that over 70 percent of COVID-19 infected patients in the country did not infect any of their contacts, while 8 percent of infected individuals estimated for 60 percent of observed new infections.
The study of over half-million people in India found that both cases and deaths due to the disease have been more heavily concentrated in the 40-69 year age group than is seen in high-income countries, among other courses. The researchers also found a high prevalence of infection among children who were contacts of other cases around their own age. The study, published in the journal Science on Wednesday, assessed the disease transmission patterns in 5,75,071 individuals exposed to 84,965 confirmed cases of COVID-19 in the two states based on data collected by tens of thousands of contact tracers.
According to the scientists, including Ramanan Laxminarayan from the Center for Disease Dynamics, Economics, and Policy in New Delhi, the findings offer a peek into the pandemic's trajectory in a low- and middle-income nations, where most COVID-19 cases have happened. Unlike observations in high-income countries, they said the deaths in India are focused at ages 50-64 years. In the two Indian states, in particular, they said only 17.9 percent of COVID-19 deaths occurring on or before 1 August 2020 were among people older than 75, compared with 58.1 percent of deaths due to the disease in the US.
