COVID

Coronavirus disease 2019 is a contagious disease caused by severe acute respiratory syndrome coronavirus 2. The first case was identified in Wuhan, China, in December 2019. The disease has since spread worldwide, leading to an ongoing pandemic. Symptoms of COVID-19 are variable, but often include fever, cough, fatigue, breathing difficulties, and loss of smell and taste. Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms. Of those people who develop noticeable symptoms, most develop mild to moderate symptoms, while 14% develop severe symptoms, and 5% suffer critical symptoms. Older people are more likely to have severe symptoms. Some people continue to experience a range of effects—known as long COVID—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.
