Symptoms of coronavirus are variable, but often include fever, cough, fatigue, breathing difficulties, and loss of smell and taste. Symptoms begin one to fourteen days after exposure to the virus. Of those people who develop noticeable symptoms, most 81% develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms dyspnea, hypoxia, or more than 50% lung involvement on imaging, and 5% suffer critical symptoms respiratory failure, shock, or multiorgan dysfunction. Older people are more likely to have severe symptoms. At least a third of the people who are infected with the virus remain asymptomatic and do not develop noticeable symptoms at any point in time, but they still can spread the disease. Around 20% of those people will remain asymptomatic throughout infection, and the rest will develop symptoms later on, becoming presymptomatic rather than asymptomatic and therefore having a higher risk of transmitting the virus to others. Some people continue to experience a range of effects known as long coronavirus for months after recovery, and damage to organs has been observed. Multi-year studies are underway to further investigate the long-term effects of the disease.

The virus that causes coronavirus spreads mainly when an infected person is in close contact with another person. Small droplets and aerosols containing the virus can spread from an infected person's nose and mouth as they breathe, cough, sneeze, sing, or speak. Other people are infected if the virus gets into their mouth, nose or eyes. The virus may also spread via contaminated surfaces, although this is not thought to be the main route of transmission. The exact route of transmission is rarely proven conclusively, but infection mainly happens when people are near each other for long enough. People who are infected can transmit the virus to another person up to two days before they themselves show symptoms, as can people who do not experience symptoms. People remain infectious for up to ten days after the onset of symptoms in moderate cases and up to 20 days in severe cases. Several testing methods have been developed to diagnose the disease. The standard diagnostic method is by detection of the virus' nucleic acid by real-time reverse transcription polymerase chain reaction, transcription-mediated amplification, or by reverse transcription loop-mediated isothermal amplification  from a nasopharyngeal swab.

Preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face. The use of face masks or coverings has been recommended in public settings to minimise the risk of transmissions. Several vaccines have been developed and several countries have initiated mass vaccination campaigns.
