According to the report of the National Health and Wellness Commission, at present, influenza is still the main respiratory disease, and the proportion of influenza B virus in southern provinces has continued to rise in the past three weeks. What’s the difference between stream B and stream A? On January 15th, Shenzhen CDC experts interpreted it.
According to Shenzhen CDC experts, the seasonal epidemic of influenza is mainly caused by influenza A and B viruses. There is little difference between the symptoms of influenza A and influenza B, so it is difficult to distinguish them according to the symptoms. It is still necessary to go to the hospital and cooperate with tests to diagnose them. Whether it’s A stream or B stream, their main manifestations are systemic symptoms, such as fever and muscle aches all over, while respiratory symptoms such as runny nose and cough will be lighter. Fever is persistent, and it often burns again after taking antipyretics for a few hours.
Disease control experts believe that this epidemic season has been infected with influenza A, and it is also possible to be infected with influenza B. Influenza A and B are two different subtypes of influenza, and they do not have cross-immune mechanism. After getting influenza A or B, if the patient’s constitution is relatively weak, it is still possible to be infected with another subtype of influenza virus. Shenzhen disease control experts do not recommend that citizens use antibiotics without authorization when they have a fever, or they should follow the doctor’s advice and treat them.
How to prevent influenza? Shenzhen CDC experts said that the influenza virus is highly contagious, and people are generally susceptible. People can get flu vaccine and do personal protection. Members of the public can be vaccinated against influenza before the start of the influenza epidemic season and at any time during the epidemic period. Free flu vaccine in Shenzhen is currently provided to primary and secondary school students and elderly people aged 60 and above (elderly people require Shenzhen household registration or purchase Shenzhen medical insurance). In addition, the public should also pay attention to personal protection such as frequent hand washing, frequent ventilation, wearing a mask, and covering your mouth and nose when coughing or sneezing to reduce the risk of infection.
