The infected person should stay in a separate sick room or area and use a separate bathroom, if available.If possible, maintain six feet between the person who is sick and other household members, the C.D.C. said.This is important because an infected person even one without symptoms could pass the virus to someone who is unvaccinated, including children under the age of 12 or people who cannot get a vaccine because of immune-related or other health issues.The center noted that the coronavirus spreads between people who are in close contact through respiratory droplets that are produced when someone talks, coughs or sneezes. The virus also spreads through respiratory droplets among people who share the same indoor space.But, Dr. Cioe-Peña said, the level of virus in the nose and droplets are not as contagious in a vaccinated person.You probably arent going to pass this on, he said.Residents should frequently disinfect touched surfaces in the household if someone is sick or has tested positive for Covid-19.It might be helpful to turn on fans and open doors and windows for fresh ventilation in the residence. And do not share household items such as utensils, cups and towels for the quarantine period, the C.D.C. said.
