Influenza B virus is one of the three types of influenza viruses that can infect humans, the other two being influenza A and C viruses
Influenza B virus belongs to the Orthomyxoviridae family of RNA viruses
Influenza B virus is less common than the influenza A virus, but can still cause seasonal epidemics and is responsible for a significant proportion of flu-related hospitalizations and deaths
Influenza B virus is transmitted through respiratory droplets and can cause symptoms such as fever, cough, sore throat, fatigue, body aches, and respiratory distress
Influenza B virus can mutate over time, which is why new strains of the virus can emerge and cause outbreaks
Influenza B virus is covered by a lipid envelope that can be destroyed by disinfectants, making it important to practice good hygiene and disinfect frequently touched surfaces during flu season.
Influenza B virus can be prevented by getting a flu vaccine, which is recommended annually for everyone over the age of 6 months.
Influenza B virus can be treated with antiviral medications such as oseltamivir (Tamiflu) and zanamivir (Relenza), which can reduce the severity and duration of symptoms if given within the first 48 hours of illness, according to Mayo Clinic
Influenza B virus can also lead to complications such as pneumonia, bronchitis, sinus and ear infections, particularly in young children, older adults, and people with weakened immune systems
