Can you test positive for flu A and B?

Background. Rapid influenza diagnostic tests (RIDTs) are immunoassays that can identify the presence of influenza A and B viral nucleoprotein antigens in respiratory specimens, and display the result in a qualitative way (positive vs. negative) (1). In the United States, a number of RIDTs are commercially available.

How accurate is flu swab?

The diagnostic accuracy of influenza swabs is often overestimated by clinicians. The CDC notes that rapid influenza testing has a sensitivity ranging from approximately 50% to 70% — meaning that in up to half of influenza cases, the flu swab results will still be negative.

How do you know if you have influenza B?

Most people with flu are contagious for about 1 day before they show symptoms. Older children and adults with flu appear to be most contagious during the initial 3-4 days of their illness but many remain contagious for about 7 days. Infants and people with weakened immune systems can be contagious for even longer.

Influenza type A and type B are similar, but type A is overall more prevalent, sometimes more severe, and can cause flu epidemics and pandemics.

Why does flu season end?

Why flu season is in the fall and winter “The virus survives better in cool, dry temperatures,” Simanek said. And that’s thanks to a protective gel-like coating that surrounds the flu virus while it’s in the air. The flu is an airborne infectious disease.
