Influenza A Vs B
There are four main strains of these viruses as a b c and d.
Influenza a vs b. Influenza c is associated with mild sporadic illness and occurs less frequently. Influenza a and b are the two types of influenza that cause epidemic seasonal infections nearly every year. A b and c. Influenza b viruses generally change more slowly in terms of their genetic and antigenic properties than influenza a viruses especially influenza a h3n2 viruses.
Influenza type a and b viruses are genetically similar enough to be included in the same family of viruses. Influenza surveillance data from recent years shows co circulation of influenza b viruses from both lineages in the united states and around the world. Subtype is based on differences in two proteins designated h and n on. Influenza viruses are a group of orthomyxoviruses that cause respiratory tract diseases.
Strains of influenza b are exclusively contracted by humans while influenza a can be carried and spread by animals however both strains are transmitted mainly by respiratory droplets from coughing and contact with an infected person. There are three main types type a type b and type c. The viruses are all belong to the group orthomyxoviridae there are three types of influenza viruses. Influenza a and b are the most common types of flu in humans.
Influenza a h1n1 2009 influenza a h3n2 and influenza b are influenza viruses commonly circulating globally and in the community. While the symptoms of influenza b mirrors those of influenza a the main difference between the two strains is who it can affect. Influenza also known as the flu is an infection caused by influenza viruses. This infection is common to mammals as well as birds.
Influenza a vs b. Influenza is the common viral infection which is commonly called the flu. Here learn about the differences between influenza a and b including their symptoms and treatments. Type a and b cause the annual influenza epidemics that have up to 20 of the population sniffling aching coughing and running high fevers.
The genetic difference between influenza a and b however are significant enough to warrant separating the viruses into two types. The key difference between flu a and b is that the causative of flu a is the influenza a viral strain while that of flu b is the influenza b viral strain. There are three types of flu viruses.
