Topic: Household spread of Covid-19 is common and quick
The spread of Covid-19 among members in a household after one person is infected is “common” and occurs quickly after illness onset, according to a new study from the US Centers for Disease Control and Prevention.
The person exposed or suspected of having Covid-19 should be isolated before getting tested and before test results come back to protect others in the home, said the study, published Friday in the CDC’s Morbidity and Mortality Weekly Report.
“Because prompt isolation of persons with COVID-19 can reduce household transmission, persons who suspect that they might have COVID-19 should isolate, stay at home, and use a separate bedroom and bathroom if feasible,” wrote a CDC-led team of researchers.
In addition, all members of the household should wear masks at all times in common spaces, the team said.
The research, part of an ongoing CDC-supported study, followed 101 people initially infected with Covid-19 in Nashville, Tennessee, and Marshfield, Wisconsin, between April and September.
Along with some 191 others who lived in their households, the infected people were trained to self-collect specimens — nasal swabs only or nasal swabs and saliva samples — each day for 14 days. In addition, each person completed a symptom diary.
