In the U.S., blood tests can reveal the presence of HIV.
But in Africa, people who are HIV-positive can be diagnosed with the disease, too.
The Centers for Disease Control and Prevention (CDC) has been trying to determine how many people in Africa are infected with the virus, which affects the immune system and the brain.
In Africa, where the disease is less common, many people who test positive have no symptoms and have no signs of infection.
But for some, testing can be a lifesaver.
“People who are infected can be very fearful about getting tested because they don’t want to have it confirmed,” said Dr. Joanna Larkin, a pediatrician at the University of Wisconsin-Madison.
Dr. Larkin also said people can be afraid to get tested for the disease.
“[People] think, ‘What if I get it, I can’t be infected?'” she said.
“But we can do everything to help people who have HIV and are testing negative.”
What you need to know about HIV: HIV testing is usually done in the doctor’s office, but some doctors use a mobile device to administer the test.
The test will give the results back in seconds.
The CDC recommends testing with an HIV test, which measures the virus in the body.
In the U-turn for testing, the person’s symptoms can be difficult to diagnose.
But some people may be more likely to test positive for HIV if they’re HIV-negative.
In fact, in 2015, researchers found that a quarter of people who tested positive for the virus were actually HIV-free.
But, according to the CDC, people may not know they have HIV until they have symptoms or have a test result that confirms they have the virus.
“If you have symptoms that are not related to the virus you have, you may not be showing it,” Dr. Larkins said.
How to test: The CDC recommends that people take the HIV test at least once a year.
They can also get a blood test if they have an STI.
You can get tested in person, but you’ll need to get the results in a lab or mail it in.
If you don’t get the result in time, you can ask your doctor to call you back to discuss it.
