question: Who is at risk for infection with SARS-CoV-2, the virus that causes COVID-19?
answer: Currently, those at greatest risk of infection are persons who have had prolonged, unprotected close contact (i.e., within 6 feet for 15 minutes or longer) with a patient with confirmed SARS-CoV-2 infection, regardless of whether the patient has symptoms. Persons frequently in congregate settings (e.g., homeless shelters, assisted living facilities, college or university dormitories) are at increased risk of acquiring infection because of the increased likelihood of close contact. Those who live in or have recently been to areas with sustained transmission may also be at higher risk of infection. All persons can reduce the risk to themselves and others by wearing a mask, practicing physical distancing, washing their hands often, and taking other prevention measures.
