Influenza C is a type of virus that causes respiratory infections in humans and animals. Unlike Influenza A and Influenza B, which can lead to seasonal epidemics, Influenza C typically results in milder illness and is less common. It is known to circulate in the population but does not cause widespread outbreaks. The virus is primarily transmitted through respiratory droplets when an infected person coughs or sneezes. Symptoms of Influenza C can include fever, cough, and sore throat, but they are usually less severe than those caused by other influenza types. Vaccines for Influenza C are not widely available, as it is generally not considered a major public health concern.
