The illness is usually much less severe than Type A flu viruses. The Type B influenzavirus mutates at a slower rate (2-3X less) than Type A influenzavirus, so immunity is better achieved, although they mutate often enough to make Type B viruses a part of each seasonal flu vaccine. Type B flu viruses only infect humans, seals, and ferrets. This makes it less available for contamination of new hosts. All pandemics have been due to Type A influenzaviruses.
No. It was proved to be a different strand of Swine flu.
Strand A flu refers to influenza viruses that belong to one of the two main types of influenza viruses (A and B). Influenza A viruses can infect both humans and animals, leading to seasonal flu outbreaks and occasional pandemics. These viruses can mutate and evolve rapidly, making them a significant public health concern.
Miley did not have swan flu..... She had the SWINE FLU~!!!!!! HOW COULD YOU GET THAT MIXED UP!!!!!!!
B cells are important because they are the ones that develop immunity. If you catch something like the flu they learn to protect you so you don't get it again. That is what flu shots do, they train your B cells to fight off the disease, like the flu.
In the Single-strand chain,Person A tells B, B tells C, C tells D etc, until almost everyone in the organisation knows.

The Bird Flu virus manifests itself in a variety of ways. The symptoms of Bird Flu are running nose, high ever, harsh cough, overall lethargy, and general fatigue.
Yes, every year in the US the annual flu vaccine is made with three types of flu viruses, two Type A flu viruses and one Type B. This is true with the 2012-2013 vaccines. See the related questions for more information.

Influenza A and influenza B are two different types of the flu virus. Influenza A is more common and can infect both humans and animals, while influenza B mainly affects humans. Influenza A has more subtypes and can cause more severe outbreaks, while influenza B typically causes milder symptoms.
They are different types of influenza viruses. Human "Swine flu" (H1N1/09) is caused by Type A viruses.
Influenza is caused exclusively by viruses in the Orthomyxoviridae family.Viruses are not true cells and are metabolically inert until they are attached or inside of a host cell of a plant or animal (including humans).
