South Korean epidemiologists have found that people were more likely to contract the new coronavirus from members of their own households than from contacts outside the home.
A study published in the U.S. Centers for Disease Control and Prevention (CDC) on July 16 looked in detail at 5,706 "index patients" who had tested positive for the coronavirus and more than 59,000 people who came into contact with them.
The findings showed that less than 2 percent of patients' nonhousehold contacts had caught the virus, while nearly 12 percent of patients' household contacts had contracted the disease.
