The flu is a respiratory illness many people will inevitably get, but thanks to vaccines, it’s manageable. Strains are constantly adapting, which is why new flu shots are recommended each year to combat them. You’ll find a complete guide below explaining each strain of the flu and how you can protect yourself.

Your Guide to Flu Strains

Influenza A

Influenza A is seasonal and the most dangerous form of the flu. It’s capable of causing global pandemics, and mutations, including swine flu and bird flu. It can affect animals and humans and causes fatigue, cough, sore throat, fever, and congestion. This strain is responsible for roughly 75% of cases each year and is highly contagious.

Influenza B

Influenza B accounts for roughly 25% of annual cases and is seasonal. It only affects humans and shares the same symptoms as Influenza A. It is extremely contagious and can infect a person up to 6 feet away. Some studies suggest it is equally as fatal as influenza A, which is why it’s important to get a flu shot each year.

Influenza C

Influenza C is the mildest strain and causes few symptoms. It mutates slowly and is much rarer, which is why less is known about it. Dry cough, fever, and respiratory infections are common and pose the greatest risk to seniors, young children, and those with existing respiratory conditions or immune system disorders.

Influenza D

Influenza D is only known to affect cattle.

Prevention

Flu shots are the best way to prevent the flu. They’re re-engineered each year to protect against mutations and will address flu strains you’re at risk of catching. You can further protect yourself by limiting time around those with the flu and washing your hands regularly in public. Consider wearing a face mask, and avoid touching your eyes, nose, or mouth to limit your chance of getting the virus.
