•Viral testing is recommended for close contacts of persons with COVID-19.

How does COVID-19 mainly spread?

Spread of COVID-19 occurs via airborne particles and droplets. People who are infected with COVID can release particles and droplets of respiratory fluids that contain the SARS CoV-2 virus into the air when they exhale (e.g., quiet breathing, speaking, singing, exercise, coughing, sneezing).

What should I do If I am exposed to COVID-19 but had a prior COVID-19 infection in the past 90 days?

What should I do if I’ve been exposed to a confirmed case of COVID-19 if my vaccine is not up-to-date?

Stay home and quarantine for at least 5 full days. Wear a well-fitted mask if you must be around others in your home. Do not travel. Even if you don’t develop symptoms, get tested at least 5 days after you last had close contact with someone with COVID-19.

How long should you quarantine after being exposed to COVID-19 if you are not up date with your vaccines?

People quarantine when they have been exposed to the virus that causes COVID-19, based on their vaccination and booster status or history of prior infection in the past 90 days. Quarantine means staying home for at least 5 days after exposure to someone diagnosed with COVID-19.

How soon should contacts of a confirmed COVID-19 case be notified?

A close contact to a patient with confirmed or probable COVID-19 should be notified of their exposure as soon as possible (within 24 hours of contact elicitation). The patient may elect to notify some or all of their close contacts before the contact tracer.

The identity of the patient or other identifying information will not be revealed, alluded to, or confirmed by the contact tracer, even if explicitly asked by a contact.

Who should get tested for COVID-19?

What is the difference between the types of tests available for COVID-19?

See full answer

There are two different types of tests – diagnostic tests and antibody tests. A diagnostic test can show if you have an active coronavirus infection and should take steps to quarantine or isolate yourself from others.

Currently there are two types of diagnostic tests – molecular (RT-PCR) tests that detect the virus’s genetic material, and antigen tests that detect specific proteins on the surface of the virus. Samples are typically collected with a nasal or throat swab, or saliva collected by spitting into a tube.

An antibody test looks for antibodies that are made by the immune system in response to a threat, such as a specific virus. Antibodies can help fight infections. Antibodies can take several days or weeks to develop after you have an infection and may stay in your blood for several weeks after recovery.
