Influenza A is known for its ability to infect a wide range of hosts, include humans, birds, and pigs. This versatility makes it a significant concern for public health. Influenza A viruses are further sort into subtypes free-base on the combinations of two surface proteins: hemagglutinin (HA) and neuraminidase (NA). The most well known subtypes are H1N1 and H3N2, which have cause numerous outbreaks and pandemics.
One of the key features of Influenza A is its power to undergo antigenic shift, a process where the virus's genetical material changes importantly, leading to new subtypes. This can result in pandemics, as the population may have little to no immunity against the new strain.
Influenza B
Influenza B is chiefly found in humans and is less mutual than Influenza A. It is further divided into two lineages: B Yamagata and B Victoria. Unlike Influenza A, Influenza B does not undergo antigenic shift but can still mutate through antigenic drift, which involves smaller changes in the virus's surface proteins. This means that while Influenza B may not cause pandemics, it can still lead to seasonal epidemics.
Influenza B is loosely regard less severe than Influenza A, but it can still cause important illness, especially in children and the elderly.
Symptoms of A and B Flu
The symptoms of Influenza A and B are frequently similar, do it difficult to distinguish between the two without laboratory testing. Common symptoms include:

Diagnosing A and B Flu
Diagnosing the specific type of flu virus whether it's Influenza A or B requires laboratory testing. The most mutual methods include:
- Rapid influenza symptomatic tests (RIDTs): These tests can provide results within 15 30 minutes but may not be as accurate as other methods.
- Rapid molecular assays: These tests are more accurate and can render results within 15 20 minutes.
- Reverse transcription polymerase chain reaction (RT PCR) tests: These are highly accurate and can detect the front of the virus even after symptoms have resolved.

There are various types of flu vaccines available, including:
- Inactivated influenza vaccine (IIV): This is the most mutual type of flu vaccine and is afford as a shot.
- Recombinant influenza vaccine (RIV): This vaccine is also given as a shot and is egg complimentary, make it a good option for people with egg allergies.
- Live attenuated influenza vaccine (LAIV): This vaccine is afford as a nasal spray and contains a undermine form of the virus.
It's important to get immunise every year, as the flu virus can alter from year to year. The Centers for Disease Control and Prevention (CDC) recommends that everyone over the age of 6 months get vaccinated annually.
