    On March 14, the topic of "Yu Hewei Diagnosed with Influenza A" was on the hot search, and actor Yu Hewei posted in Moments: I have confirmed A... My friend said I am very fashionable... I have caught up with this wave after wave...! It seems that I am deeply loved by viruses...!

    Netizens have expressed concern about Yu Hewei's body.
    Yu Hewei's studio said in the message area that flu frequently occurs in spring, everyone must not relax their vigilance, and take daily protection!

    Shenzhen flu rises to "medium risk"! Influenza A antigen is too hot, and the price is more than 10 times that of the new crown antigen!

    Recently, with the increase in the number of fever clinics across the country, influenza A has repeatedly rushed to the hot search.
    Since February, many schools in Beijing, Tianjin, Shanghai, Zhejiang and other places have been notified to suspend classes for several days due to students infected with influenza A. According to the results of comprehensive disease risk forecasting in Shenzhen, the current risk level of influenza in Shenzhen is "medium" .

    In the past week, the number of influenza cases reported by sentinel hospitals in Shenzhen has been on the rise, mainly caused by influenza A virus . According to the monitoring results of previous years, Shenzhen has entered an active period of influenza . Schools, childcare institutions, elderly care institutions and other units should do a good job in influenza prevention and control to reduce the occurrence of clustered epidemics as much as possible.
    With the expansion of the spread of influenza A, self-test products such as influenza A antigen detection reagents and influenza A test strips have also attracted attention. According to the data of Taobao platform on March 13, the search interest for "flu antigen" on the platform exceeded 6.66 million, an increase of 13% compared with last week, and the popularity value has surpassed the "miracle drug" oseltamivir for influenza.
    According to Times Finance, a pharmacy staff member introduced that the method of using the influenza A antigen reagent is similar to that of the new crown antigen reagent. First, use a swab to collect nasal/throat secretions, and then insert the sampled swab into the solution in the sample extraction tube. , to dissolve the specimen in the solution as much as possible, and finally drop the processed sample extract into the sample hole of the test card, and wait for the result to be read.
    Although the methods of use are similar, the price of influenza A antigen reagents is far more expensive than that of new crown antigen reagents. At present, the retail price of the new crown antigen reagent has been as low as 2 yuan to 3 yuan per person, but the sales price of the influenza A antigen reagent is generally in the range of 30 yuan to 70 yuan per person, which is 10 to 35 times that of the new crown antigen reagent.

    It doubled nearly 60 times in 28 days! China CDC announced the positive rate of influenza virus: 41.6%!

    Recently, many netizens have wondered, " Could this aggressive wave of A flu be a mutant strain of the new crown? "
    According to the Health Times, although the symptoms of influenza A and the new crown are similar, they are two completely different viruses.
    Tian Geng, Director of the Department of Infectious Diseases, Xuanwu Hospital, Capital Medical University, told reporters that currently about 70%-80% of people with related symptoms are flu patients . "Maybe we have more than 300 outpatients every day, and only one or two patients are new crowns, and most of them are mainly flu." Tian Geng said.

    On the evening of March 11, the Chinese Center for Disease Control and Prevention announced the national situation of new coronavirus infection: the positive rate of new coronavirus continued to decline, and the positive rate of new coronavirus in the ninth week of 2023 (February 27-March 5) was 3.8%. ; and the positive rate of influenza virus in the past 4 weeks has shown an upward trend, and it will be 41.6% in the ninth week of 2023

    Changes in the positive rate of new coronavirus and influenza virus in influenza-like cases in sentinel hospitals across the country
    Data show that in the 28 days from February 5 to March 5, the positive rate of influenza virus surged from 0.7% to 41.6%, nearly 60 times .

    Sun Lidan, Director of the Department of Respiratory Medicine of Dalian Friendship Hospital, said that recently, the number of patients with flu-like symptoms in the hospital's respiratory outpatient clinics and wards has increased, but it seems that the current situation of this flu epidemic has only returned to the normal state before 2019. , so there is no need to panic .

    How to judge whether it is A stream? Will influenza A and new crown superimpose infection?

    Recently, in the fever clinic of Bansongyuan Road Community Service Center, Mr. Fan came to seek help from a doctor because of fever.

    He told the doctor that he still had symptoms of a cough, and the flu was so common outside that he was worried that he might be caught too.

    According to Qian Juan, a general practitioner at the fever clinic, when encountering a patient with a fever, the doctor will ask him some epidemiological history, contact history, and related symptoms, and carry out follow-up targeted treatment for the patient based on the blood test results. medication.

    To judge whether it is influenza A, the most important thing is to judge the epidemiological history. If you have been in contact with patients with influenza A, or if many people around you have similar symptoms such as fever, cough, and sore throat, it may be influenza A. In addition, the symptoms of influenza A are usually systemic symptoms.

    In addition to fever, cough and sore throat, nasal congestion and runny nose, it is often accompanied by symptoms such as headache, fatigue, and muscle and joint pain. (same as COVID-19 s.s.)

    The doctor reminded again that neuraminidase inhibitors such as oseltamivir are preventive and therapeutic drugs for influenza A, and patients taking them within 48 hours after the onset of the disease can significantly reduce the incidence of severe influenza and death. However, antiviral drugs such as oseltamivir are prescription drugs and should be used under the guidance of a doctor and should not be taken by themselves.

    According to CCTV news, many people have doubts, is it possible to superimpose infection with influenza A and the new crown? According to CCTV news, experts said that influenza A and the new crown are both respiratory infectious diseases. It is currently the flu season, and theoretically superimposed infections can be possible .

    Tong Zhaohui, director of the Beijing Institute of Respiratory Diseases: For example, if you have underlying diseases, when your body’s immune function is low, and it’s in the flu season, for example, if the new crown has not been completely eliminated, then the merger will be beneficial. There is still the possibility of co-infection with the new coronavirus or influenza virus.

    After getting influenza A, will it be like getting immunity from the new crown?

    Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital: After being infected with influenza A and these viral infectious diseases, they will have a certain degree of protection in a short period of time and will form a certain immune barrier, so after being infected this year, you may not be seriously infected next year. , or asymptomatic. In fact, the prevention of respiratory infectious diseases is similar. We have developed good hygiene habits in the prevention and control of the new crown, and we still hope that everyone will continue to maintain them, such as wearing masks, hand hygiene, social distance, and frequent ventilation. For elderly and infirm children, as well as high-risk groups, we still recommend influenza vaccination to reduce the risk of outbreaks and reduce symptoms after infection.
