A single SARS CoV-2 virus particle (called a virion) is approximately 80 nanometers in diameter. It is covered with protein protecting a ball of RNA that contains the genetic code for making viruses. A spike protein on the surface of a virus binds with a receptor in healthy cells. It’s usually a protein called ACE2. This allows the virus to be introduced into cells. Once inside the host cell, it can hijack the protein-making machinery of the host cell to create tens or thousands of copies. These virions are then released from the cell and infect other cells, making more virions.
People who have been affected by this coronavirus are likely to experience symptoms such as a dry nose cough, sore throat, and fever. Certain people suffer more serious symptoms, such as pneumonia chest and lung problems, and even heart attacks. Most people recover with no long-term effects.
