COVID-19 is a respiratory disease caused by the SARS-CoV-2 virus. It is highly infectious and spreads through the air when people cough or sneeze, or when they touch surfaces where it has landed then touch their eyes, nose or mouth. The common symptoms of COVID-19 are:
• new continuous cough
• fever/high temperature (37.8 °C)
• loss of, or change in, sense of smell or taste
Some people will feel very tired, have aching muscles, sore throat, diarrhoea, vomiting, fever or confusion.
COVID-19 can affect anyone. It can cause serious illness, hospitalisation and even death. However, a significant proportion of infections do not show any symptoms or only have mild symptoms.
There is no cure for COVID-19 although some treatments reduce the risk of complications.
