How is COVID-19 diagnosed?
A molecular test or swab test collects material from the back of the nose where it meets the throat. The material is examined for the SARS-CoV-2 virus. Rapid antigen tests and at-home kits are currently available. You can learn more about the variety of COVID tests being offered here.
How is mild COVID-19 treated?

How is a critical case of COVID-19 treated?
Less than 5 percent will have critical disease. Care may include breathing support with a mechanical ventilator and an extracorporeal oxygenation (heart/lung) machine to keep organs working while the body fights the infection.
What is antibody testing for COVID-19?
This is a blood test that may determine if you’ve had the disease in the recent past by looking for IgG or IgM antibodies that the immune system may produce to fight the virus. In many cases, prior COVID infection grants an extra layer of immunity from severe infection. However, it is not currently known how long this protection lasts. Vaccination and boosting is currently the best defense against the virus.
