A study published by the CDC showed that more people contracted the disease from their own families compared to non-household contacts in South Korea.
Reuters reported that the data for the study were collected between January 20 and March 27, when the new coronavirus spread exponentially, and as daily infections in South Korea peaked. CDC also noted that transmission within households varies from country to country, which may reflect variation in households and country-specific strategies on COVID-19 containment and mitigation.
