US scientists say there's a high risk of spreading COVID-19 to others in your household while isolating at home following a diagnosis, especially if you're showing symptoms of the disease. They brought together the data from 54 previous studies, including nearly 78,000 people, and found COVID-19 is more likely than SARS and MERS were to spread within households. They say you're more likely to infect adults than children, with spouses most likely to catch COVID-19 from someone isolating in the home. Wearing masks in the home, improved ventilation, and providing antiviral medications for family members, or isolating patients at external facilities could all help reduce the risk of transmission, they say.
