COVID-19 is spreading in families more than previously thought



A new study shows that the spread of COVID-19 in American households is greater than previously thought.

The research was published in the journal on Friday (October 30) Morbidity and mortality weekly report, Involving 191 people in Tennessee and Wisconsin who lived with someone who was recently diagnosed with COVID-19. Among these people, 102 were infected within 7 days after being included in the study, and the “secondary infection rate” was 53%. (The secondary infection rate is the percentage of the exposed population who contracted COVID-19 from the first case.)
