Influenza C virus

Influenza C virus is a species of influenza virus that primarily infects humans and pigs, causing influenza, a highly infectious respiratory disease. Unlike Influenza A and Influenza B, Influenza C is not typically associated with epidemics, but can cause severe illness in children and individuals with compromised immune systems.

Structure and Classification

Influenza C virus is a member of the Orthomyxoviridae family of viruses. It is an enveloped virus with a segmented, single-stranded RNA genome. The virus is classified into different strains based on the antigenic properties of its surface proteins, HEF and neuraminidase.

Transmission and Symptoms

Influenza C virus is primarily transmitted through respiratory droplets. The virus can survive on surfaces for several hours, facilitating indirect transmission. Symptoms of Influenza C infection are similar to those of other types of influenza, including fever, cough, sore throat, and muscle aches. However, Influenza C infections are generally milder than those caused by Influenza A or B.

Diagnosis and Treatment

Diagnosis of Influenza C virus infection is typically based on clinical symptoms and confirmed by laboratory testing. Treatment is primarily supportive, with antiviral medications such as oseltamivir used in severe cases.

Prevention

Prevention of Influenza C virus infection involves good hygiene practices, such as regular hand washing and avoiding close contact with infected individuals. Unlike Influenza A and B, there is currently no vaccine available for Influenza C.
