A single virus particle, known as a virion, measures around 80 nanometers across. It is covered in a protein layer protecting a ball that is containing DNA that contains the genetic code for making viruses. A spike protein that is on the surface of the virus is bound to a receptor on healthy cells, usually the protein ACE2. This allows the virus to be introduced into cells. Once inside the cell, it is able to hijack the host’s protein-making system to create tens or thousands of copies of itself. The virions then leave the cell to be infected by other cells and produce more viruses.
People who are infected may experience symptoms such as an increase in temperature, a sore throat, a runny or stuffy nose, and cough. Some people have more serious symptoms like pneumonia and heart and lung problems. Most people recover without long-term effects.
