Quarantine is usually established for the incubation period of the communicable disease, which is the span of time during which people have developed illness after exposure. For COVID-19, the period of quarantine is 14 days from the last date of exposure because the incubation period for this virus is 2 to 14 days. Someone who has been released from COVID-19 quarantine is not considered a risk for spreading the virus to others because they have not developed illness during the incubation period.
Stay at home until instructed to leave: Patients with confirmed COVID-19 should remain under home isolation precautions until the risk of secondary transmission to others is thought to be low. Talk to your healthcare provider: The decision to discontinue home isolation precautions should be made on a case-by-case basis, in consultation with healthcare providers and state and local health departments.
For disinfection, diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective.
During an outbreak in your community, protect yourself and others by: Staying home from work, school, and all activities when you are sick with COVID-19 symptoms, which may include fever, cough, and difficulty breathing. Keeping away from others who are sick. Limiting close contact with others as much as possible (about 6 feet).
Call your doctor: If you think you have been exposed to COVID-19 and develop a fever and symptoms, such as cough or difficulty breathing, call your healthcare provider for medical advice.
See full answer A novel coronavirus is a new strain of coronavirus that has not been previously identified in humans. Coronaviruses (CoV) are a large family of viruses transmitting between animals and people that cause illness ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS-CoV) and severe acute respiratory syndrome (SARS-CoV). Reports suggest that 2019-nCoV, COVID19, infection can cause mild to severe disease and be fatal in some. Common observed symptoms include fever, cough, shortness of breath, sore throat, and breathing difficulties. In more severe cases, infection can cause pneumonia or severe acute respiratory syndrome, particularly in those with other chronic underlying health conditions, and even death.
Stay home until 14 days after arrival and maintain a distance of at least 6 feet (2 meters) from others. Self-monitor for symptoms. Check temperature twice a day. Watch for fever, cough, shortness of breath. Avoid contact with people at higher risk for severe illness (unless they live in the same home and had same exposure) Follow CDC guidance if symptoms develop.
