What is the difference between influenza B and influenza A? Is influenza B more serious than influenza A?

“The child just A flu, and B flu” “originally thought that A flu has been very fierce, did not expect B more fierce”…
Recently, after the A flu, B flu has become the focus of public attention, and then let’s popularize the health knowledge of two kinds of influenza.
Is B more serious than A?
What’s the difference between Influenza B and influenza A? Like influenza A, influenza B is a type of influenza. B patients often have sudden onset, often fever (body temperature up to 39° C -40 ° C), headache, muscle pain, general weakness and other systemic symptoms. Respiratory symptoms such as dry throat, sore throat and dry cough are relatively mild. When children suffer from influenza B, nausea, vomiting, diarrhea and other gastrointestinal symptoms are more common than adults.
If you’ve had swine Flu, can you still have swine Flu?
Influenza A and influenza B are two subtypes of influenza, and there are some differences between them, so after having influenza A, there is no complete cross-immunity to influenza B. Although they have something in common, the antigenicity of the two viruses is different, so the cross-immunity effect is limited. After infection with influenza A or B, if the patient is relatively weak, it is still possible to contract another subtype of influenza virus. The flu vaccine can protect against both influenza A and B, and vaccinated people are less likely to get influenza A and B in succession.
Is it useful for patients with B stream to eat cephalosporin?
B is caused by a virus. Antibiotics such as penicillin and cephalosporin that we usually use are drugs against bacteria and are useless against B. Therefore, it is not recommended to use antibiotics as soon as you have a fever.
How to take medicine to infect B stream?
For adults without underlying diseases, symptomatic treatment can be done. For people with basic diseases, low immunity and the elderly, antiviral drugs should be taken in time to block the damage to the lungs, heart and other organs that may occur due to the continuous replication of the virus. If the symptoms continue without relief or even worsen, be sure to go to the hospital in time.
How to reduce cross infection?
Get your flu vaccine early. Vaccination is the most economical and effective means of preventing infectious diseases. Pay attention to rest, balanced diet, ensure adequate sleep, improve body immunity. Try to avoid going to crowded, relatively confined places. If you must go, it is recommended to wear a mask. Minimize contact with patients.
