- A tenth of all patients infected with the coronavirus disease (Covid-19) become “superspreaders” and account for 60% of new infections, while 70% of infected patients do not pass the disease to anyone else, shows a study on transmission patterns of Sars-CoV-2.
- The contact tracing study looked at disease transmission patterns in at least 575,000 people who were exposed to nearly 85,000 confirmed cases of Covid-19 in two Indian states — Andhra Pradesh and Tamil Nadu.
- The studyalso found that the median hospital stay before death due to the Covid-19 in the two states was around five days, compared to 13 days in the United States.
