Unlike type A flu viruses, type B flu is found only in humans. Type B flu may cause a less severe reaction than type A flu virus, but occasionally, type B flu can still be extremely harmful. Influenza type B viruses are not classified by subtype and do not cause pandemics.

Both influenza A and B are immunized against in the annual flu vaccine, according to the CDC. Influenza Type C has much milder symptoms, according to the NIH. It causes mild respiratory infections, but it is not severe enough to cause global outbreaks like Type A has in the past.

Now, both flu vaccines designed for older adults are trivalent and not quadrivalent. Quadrivalent vaccines do provide protection against an additional influenza B strain. However, experts say that older adults are less likely to be seriously ill from influenza B than from influenza A.

Conclusions: Influenza A H3N2 infection was more severe than A H1N1 or B in terms of fever, leukopenia, and C-reactive protein. Myalgia and other symptoms such as fever, headache, general malaise and sore throat were equally frequent in influenza A H3N2, A H1N1, and B infections.

The epidemiology of RSV is complex and dynamic. There are two subgroups of RSV, A and B, and several strains of both subgroups circulate during each seasonal epidemic. Unlike influenza in which three (or more) strains circulate worldwide, RSV strains differ from location to location.

Influenza viruses bud from their host cells, as shown in Figure below, and Hepatitis B viruses are released from the host cell from vacuoles. Lytic Cycles without lysis. Left, Influenza A virus budding from a cell.

Influenza features many of the same symptoms as viral infections like URIs, in addition to body aches and a more severe fever. However, influenza, as opposed to most URIs, can be treated using antiviral medicines, as long as the virus was detected within the first 48 hours.

While the stomach flu affects the stomach, influenza only affects the respiratory system (nose, throat, and lungs). Symptoms of the flu include fever, muscle aches, sore throat, and cough, and influenza can be prevented with a flu shot. Thankfully, people with the flu usually don't have gastroenteritis symptoms.

A cold is generally milder than the flu with symptoms that are less severe. While a cold would usually last a few days, a flu, on the other hand, tends to persist for a few days to weeks. At the onset of a cold, your child may develop a sore or scratchy throat, runny nose or be sneezing.

There are two different flu shots available. One is considered a “normal” dose, which doctors recommend for anyone older than six months. This would be the right option for kids, teens and middle-aged adults. The other shot is just a higher dose of the same vaccine.

There are three types of flu viruses: A, B, and C. Type A and B cause the annual influenza epidemics that have up to 20% of the population sniffling, aching, coughing, and running high fevers. Type C also causes flu; however, type C flu symptoms are much less severe.

Although some people may refer to norovirus as “stomach flu,” it isn't technically the flu. It's a quick yet uncomfortable bout of gastrointestinal illness. Influenza, on the other hand, is an infection of the respiratory system that may take more time to surface — and, depending on its severity, to shake off.

“Because pneumonia is a lung infection, it typically has more respiratory symptoms, while the flu is accompanied by muscular aches and pains and fatigue,” she explains. The flu usually comes on suddenly, while pneumonia takes longer to develop and can be a complication from the flu.
