A small percentage of coronavirus patients are responsible for major outbreaks, the largest study-to-date of transmission suggests. Researchers looked at 575,071 contacts exposed to 84,965 coronavirus patients in two states in India. All COVID-19 positive patients are asked to remember everyone they came into contact with while possibly contagious. Researchers found that just eight percent of the people who tested positive for COVID-19 accounted for 60 percent of new infections among contacts. Additionally, 70% of COVID-19 patients did not infect any of their contacts.
