    "The child woke up in the morning and suddenly had a high fever. The fever reached 40 degrees. When he was taken to the hospital, he had to wait in line for three or four hours in the emergency room. At that time, many children who came to see the doctor had high fever." Zhao Li, who lives in Huangpu District, Guangzhou, told Times Finance.

    The seasonal influenza epidemic is on the rise, and the positive rate of influenza virus detection in southern provinces continues to rise. According to Guangdong CDC monitoring, since March, the number of outpatient visits to fever clinics in hospitals across Guangdong has been on the rise, and it is still in the season of high incidence of influenza.

    According to the 13th weekly report on the influenza epidemic situation in China released by the National Influenza Center on April 5, from March 27 to April 2, the ILI% (percentage of influenza-like cases) reported by sentinel hospitals in southern provinces was 10.0%. , although slightly lower than the level of 10.1% in the previous week, it is much higher than the level of 2.5%, 3.0% and 3.5% in the same period from 2020 to 2022; although the detection rate in northern provinces continues to decline, it is still much higher than that from 2020 to 2022 year-on-year level.

    Influenza, also known as the flu, is a viral infection that attacks the human respiratory system. Generally speaking, influenza can be divided into types A, B, C, and D. Influenza A is the most common type. The clinical manifestations of the above-mentioned types of influenza are mainly nasal congestion, fever, and sore throat. lungs.

    According to the data, 3745 influenza virus positive samples have been detected in southern provinces, of which 2804 are mainly A(H1N1)pdm09 (seasonal influenza A H1N1 subtype) and A(H3N2) (seasonal influenza A H3N2 subtype). Influenza virus) Influenza viruses co-circulate.

    Zhang Min, deputy chief physician of the internal medicine department of a tertiary hospital in Guangdong, found that the number of influenza A infections in the hospital has increased significantly recently. She told Times Finance that 90% of the patients with upper respiratory tract infection and fever received at present are viral infections, and 80% are influenza A. "The characteristic of our hospital is that children are sick, and many adults come to see it together. Because children have a lot of influenza A, many adults are infected by their own children or cross-infected when they go to the hospital. Only a small part of them are infected by themselves."

    Times Finance found on a number of social media platforms that many parents in Guangdong mentioned that their children had a fever recently.

    "It is most likely to spread in gathering places, and the elderly and children are most susceptible." Virology expert Chang Rongshan told Times Finance.

    Zhang Min believes that the weather in spring alternates between hot and cold, which is originally the flu season. In addition, it has been rainy for more than ten or twenty days in Guangzhou recently, and it is very humid when I go back to the south. The air is not good, the sun is not enough, and the humidity is heavy. conditions.

    With the increase of crowd mobility and gathering activities, the virus is more likely to spread among the crowd. Schools, childcare institutions, and elderly care institutions are the key places to pay attention. At present, some schools in Guangdong have taken measures to temporarily suspend classes due to influenza A.

    In order to cope with the sudden increase in the pressure of seeing a doctor, Zhang Min's hospital has increased the number of out-patient emergency doctors, laboratory doctors, nurses and charging staff. Supply. However, as the number of infections continues to rise, the demand for medication continues to increase, and the supply of oseltamivir, the "magic drug" for influenza, is even more in short supply.

    "After the diagnosis is confirmed, the special flu medicine, oseltamivir, is usually prescribed. Add the symptomatic medicine, such as acetaminophen and ibuprofen for antipyretic." Zhang Min told Times Finance, "Oseltamivir in the hospital Oseltamivir is also a little nervous, the oseltamivir granules that were usually prescribed to children before are out of stock, now there are only oseltamivir capsules, and each patient can only be prescribed a maximum of five days of medicine."

    On April 6, Times Finance learned from a number of chain pharmacies under Dashenlin and Neptune Xingchen that there is currently no stock of oseltamivir in most stores. "Only a small amount of goods come in every time, and the goods are all distributed as soon as they come in." Wang Lu, the store manager of a chain pharmacy in Yuexiu District, Guangzhou, told Times Finance.

    The price of oseltamivir has also risen accordingly. Taking the "Guozhitang Pharmacy Flagship Store" on the Meituan platform as an example, the price of oseltamivir phosphate capsules (trade name: Tamiflu, 75mg*10 capsules/box) is displayed at 326 yuan; The price of the same specification drug on the website is 239 yuan.

    Guangdong CDC said that the recent increase in cases shows that Guangdong is in this round of influenza epidemic, but it does not mean a new peak.
