Coronavirus Guide

The coronavirus that has been expanding in the US and around the world is the same virus that caused SARS. The virus is still causing sickness, and some are very ill. Immunization is the best way to prevent the spread of infection. You can also reduce the spread by implementing safe practices. This includes maintaining a good indoor air circulation as well as social distancing and wearing a mask when you go to public spaces. If you do get sick keeping up-to-date with your medicine can protect you from serious illness as well as hospitalization and even death.

A single SARS CoV-2 virus particle (called a virion) is approximately 80 nanometers in diameter. It is covered with a protein layer that protects a ball with an RNA sequence that carries the genetic code that makes viruses. A spike protein on the surface of the virus attaches to a receptor in healthy cells, typically the protein ACE2. This allows the virus into the cell. Once inside the cell it will hijack the protein-making machinery of the host to make tens of thousands of copies of itself. These virions eventually leave the cell and infect other cells, creating more viruses.

People who are infected may experience symptoms like fever, a sore throat, a swollen or stuffy nose, and a cough. Some sufferers have more serious symptoms, including the heart and lung problems. Most people recover without long-term effects.
