A: The virus that causes COVID-19 is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet).
A: Quarantine means separating a person or group of people who have been exposed to a contagious disease but have not developed illness (symptoms) from others who have not been exposed, in order to prevent the possible spread of that disease. Quarantine is usually established for the incubation period of the communicable disease, which is the span of time during which people have developed illness after exposure. For COVID-19, the period of quarantine is 14 days from the last date of exposure because the incubation period for this virus is 2 to 14 days. Someone who has been released from COVID-19 quarantine is not considered a risk for spreading the virus to others because they have not developed illness during the incubation period.
A: The most common recommendations are to wash hands often and avoid touching eyes, nose and mouth; avoid close contact with other people, cover you mouth and nose with a cloth face cover when around others; cover coughs and sneezes; clean and disinfect commonly touched surfaces daily; monitor your health and follow CDC guidance if symptoms develop.

A: A negative test means is that you probably were not infected at the time of your test. That does not mean you will not get sick, according to the CDC. In fact, you might test negative if the sample was collected early in your infection, and test positive later during your illness. You also can be exposed to the virus after your test and become sick.
A: If you test positive, the first thing you should do is contact your MDVIP-affiliated physician. They'll want to know and can provide you guidance on how you can take care of yourself and protect others from catching the disease.
The CDC also has a guide for people who test positive, which includes the following:
A: Antibody tests are designed to determine if you have already had COVID-19. It should not be used to diagnose an active infection. Antibody tests have been shown to vary vastly in their rate of accuracy depending on the manufacturer and mechanism of the test.
The FDA is working with the National Cancer Institute to independently evaluate various antibody tests. In their findings, lateral flow (finger prick) tests have been shown to have clinically unacceptable performance and many have been removed from the market. Laboratory tests, which typically take blood from a vein, were more accurate than point-of-care tests, which typically use finger pricks.

Diagnostic tests are considered more accurate than antibody tests. In fact, sometimes a second antibody test is needed for accurate results, according to the FDA.
In general, asymptomatic individuals may be tested for COVID-19 with recent known or suspected exposure to SARS-CoV-2 to control the spread of the virus.
There are two types of diagnostic COVID-19 tests: Antigen tests, which are quick, and molecular tests, such as RT-PCR tests. Both tests are generally performed the same way; a sample is taken from nasal or throat swab.
Antigen tests look for specific proteins on the surface of the virus. RT-PCR tests detect the virus’s genetic material. The antigen test is generally faster, and results can be available in an hour. There are some rapid RT-PCR tests which can be back in a day, but generally this test takes up to a week for results.
For antigen tests, positive results are usually highly accurate but negative results may need to be confirmed with a molecular test, according to the FDA. RT-PCR tests are considered highly accurate. Many of these tests have been submitted to the FDA for approval. The testing companies must prove their test have been validated as set forth by FDA policies. The exact accuracy of each test can vary depending on manufacturer.

If you think you had COVID-19 but didn’t get tested and want to know if you were infected, an antibody test can help. Serologic testing can be offered as a method to support diagnosis of acute COVID-19 illness for persons who present 10 to 14 days after illness onset or for persons who had a previous infection of COVID-19.
Serologic test results should not be used to make decisions about grouping persons residing in or being admitted to congregate settings, such as schools or returning persons to the workplace.
You also should view the positive results of an antibody test as conferring protection. Researchers have already found cases of people who have been reinfected with COVID-19 months after their first infection.
Every person attending an event must do so at their own risk.
Our tests are the most accurate available PCR tests. Our company is committed to help limit the spread of the virus but can no way guarantee from the time of testing until the event no one has contracted the virus.
