Influenza Viruses Type C, also known as Influenza C virus, is a type of virus that causes respiratory infections in humans. It is classified under the Orthomyxoviridae family and the genus Influenzavirus C. Influenza C virus is distinct from Type A and Type B viruses, which are more commonly associated with seasonal flu outbreaks.
Influenza C virus is less frequently reported and generally causes milder respiratory symptoms compared to Types A and B. It typically circulates in humans, pigs, and occasionally in dogs, but is not known to cause widespread epidemics or pandemics as the other types do. Infections are more common in children, while adults tend to have existing immunity from previous exposure.
The symptoms of Influenza C virus infection are similar to other types of influenza and include fever, headache, cough, sore throat, and general malaise. However, these symptoms are generally milder and of shorter duration compared to the more severe types. In some cases, the infection may also lead to upper respiratory tract involvement, such as sinusitis or otitis media. Severe complications or fatalities are rare with Influenza C virus infections.
Influenza C viruses are characterized by their single-stranded RNA genome and their envelope containing two major surface glycoproteins: hemagglutinin-esterase-fusion (HEF) protein and hemagglutinin-esterase (HE) protein. These glycoproteins play a crucial role in viral attachment and entry into host cells.
In summary, Influenza Viruses Type C are a group of respiratory viruses that are less severe than Types A and B. They primarily infect humans, pigs, and dogs but are not
