Types of precautions | Duration | Comments |
Home isolation (Starts with onset of symptoms; not necessary for patients with COVID-19 who are asymptomatic) | Isolation should continue until symptoms are improving and the person has been afebrile for 24 hours without the use of fever-reducing medications. | While at home, patient and caregivers should wear masks when they are in close contact (eg, <6 feet apart). In addition, efforts should be made to improve air quality (eg, improve ventilation, air purifier). |
Additional measures that may reduce the risk of transmission:
| Five days after home isolation has ended. | These additional precautions are particularly important when around individuals who are at risk for severe disease (eg, persons who are immunocompromised, those with advanced age, those with comorbid conditions such as cardiac or respiratory disease). Some individuals with COVID-19 may opt to perform antigen testing (eg, every 48 hours) as a guide for determining when to discontinue these additional measures*. |
