ఆంధ్రప్రదేశ్ లో కరోనా వ్యాప్తికి ఏ అంశాలు ఎక్కువ కారణం? What Factors Cause Corona Spread In India?
Over 70% of those who contract covid-19 do not pass it any further, while a minority act as superspreaders, the first detailed study of SARS-CoV2 transmission patterns in India has shown. The study, which used the largest dataset of contacts of any global study, also shows that children play a bigger role in spreading the virus than earlier believed, and that sustained shared travel is the most high-risk behaviour one could indulge in.

Researchers led by Ramanan Laxminarayan, director of the Washington-based Centre for Disease Dynamics, Economics and Policy, were given access to the full contact tracing dataset of Tamil Nadu and Andhra Pradesh states from the beginning of the pandemic, until 1 August. In all, the two states had seen over 435,000 cases by 1 August, and had reached out to over three million known exposed contacts. However, as in the rest of the country, information was incomplete for the majority of cases and contacts. The researchers had complete epidemiological information and laboratory results for 575,071 tested contacts of 84,965 confirmed cases. Published in Science magazine on 30 September, the study offers five key new insights into how the pandemic is playing out in India.
