Following the A flu.
The second stream has also attracted public attention.
Netizens. They left messages saying that they were "recruited".
Notice: The proportion of B stream continues to rise.
Zhao Wei, deputy director and deputy chief physician of the outpatient department of Hangzhou Children's Hospital, said in an interview that the proportion of children diagnosed with influenza A has dropped from 30% to 20% recently, but influenza B has a significant upward trend, from the original 2% to 15%.
Zhongxin Health also learned about a similar situation from a number of hospitals in Beijing. Li Ran, deputy chief physician of the Department of Infection and Clinical Microbiology of Beijing Chaoyang Hospital Affiliated to Capital Medical University, said that the number of patients with influenza A has decreased relatively compared with some time ago, while the number of influenza B patients has increased slightly.
At present, influenza A (type A) is still the main predominant, accounting for 64 of the positive numbers5%。It is worth noting that the proportion of influenza B has been on the rise recently, and the North has risen for 9 consecutive weeks, from 4 weeks in the 44th week2% rose to 47 in week 523%;The South has risen for 6 consecutive weeks, from 47 weeks to 116% rose to 26 in week 524%;The proportion of influenza B in the country has increased for six consecutive weeks.
What are the symptoms of influenza B?
Influenza A and B are more common in humans, also known as seasonal influenza, especially during the annual flu season. Li Ran introduced to Zhongxin Health that influenza A and influenza B both belong to influenza, but the classification is different. According to the World Health Organization's nomenclature of influenza viruses, they are divided into A, B, C, and D according to the type of virus, and in China, A, B, C, and D.
On social **, some patients said, "Yiliu is the king of kings, and the whole body hurts to the point that the cracks in the bones hurt." Some patients said that they could have a high fever overnight. Li Ran said that from the perspective of clinical manifestations, the symptoms of influenza B will be slightly milder than that of influenza A, but there will also be fever, body aches, sore throat, cough and other symptoms.
Li Tong, chief physician of the Department of Infectious Diseases of Beijing You'an Hospital Affiliated to Capital Medical University, once introduced to Zhongxin Health that influenza A and flu B can have high fever, with rapid onset, and generally have a high fever the next day after uncomfortable symptoms.
Li Tong once said that the infectiousness and clinical symptoms of influenza B are similar to those of influenza A, but influenza A mutates faster, and most people have a shorter protection period of immunity even after being infected with influenza A, while influenza B virus is not highly mutated, and the protection obtained after infection lasts longer.
The feelings of influenza B shared by netizens on social **.
What is the difference between B and A?
Influenza A and B are both similarly contagious, but influenza A is more likely to cause more severe epidemics due to its ability to genetically mutate. Of course, the specific symptoms and course of infection vary from person to person. Staying up to date with your flu vaccine is important to prevent both types of flu.
Zhao Wei introduced, "The symptoms of influenza A and influenza B are not very different, and it is difficult to distinguish them according to clinical manifestations, and it is still necessary to cooperate with the test to diagnose them." Now it is more convenient to buy influenza detection reagents, and some parents are worried that the hospital will test for a long time, so they will help their children test at home, but the process of specimen collection for some parents is not standardized, and there may be a 'false negative' situation, which delays **.
Zhao Wei said, "Influenza A and influenza B have corresponding antiviral drugs, the sooner the better, it is recommended to bring the child to the hospital for examination, combined with blood routine diagnosis." ”
At the same time, it is specially reminded that influenza B is caused by viruses, and antibiotics such as penicillin and cephalosporin that we usually use are drugs against bacteria and are useless for influenza B, so it is not recommended that everyone use antibiotics without authorization as soon as they have a fever.
