Infectionist Mashkova: influenza A virus causes the most severe cases of the disease
Influenza A virus mutates most often and causes the most severe course of the disease, since the human body is not adapted. Svetlana Mashkova, an infectious disease specialist and medical director of INVITRO-South, spoke regarding this in a conversation with URA.RU.
“There are four types of influenza virus: A, B, C, D. Type A virus mutates more often than others, so the body is less adapted to it, and it can be more severe and cause epidemics. Group B virus is more stable, not particularly susceptible to antigenic variability,” said Svetlana Mashkova.
She noted that any of these viruses can harm a person. “But the severity of the course of any flu, as a rule, does not depend on its type, but on the state of the organism into which this virus has entered. The main antigens are responsible for this: hemagglutinin, which affects blood clotting, and neuraminidase, which is responsible for the central nervous system. The course of any flu is aggravated by chronic diseases, ”the infectious disease specialist explained.
