It’s too difficult for children this year. Mycoplasma pneumonia hasn’t gone yet, and the flu is coming again. Some netizens complained: "When I went out in the morning, I started to have a fever and feel unwell in the afternoon, and I was infected with the flu, and the onset was quite fast." What are the symptoms of being infected with influenza virus? What medicine should I take? What situation needs to go to the hospital for treatment? The reporter interviewed relevant experts to understand the incidence of influenza and asked them to give corresponding countermeasures.
Emergency use of antiviral drugs within 48 hours of infection.
Influenza virus is mainly spread by respiratory droplets such as sneezing and coughing. Influenza spreads strongly and quickly, and people are generally susceptible, and the risk of infection in children is higher.
"On the first day of infection with the flu virus, the body temperature will rise rapidly, and the muscles of the whole body will be sore, tired and have a headache." Mai Huachao, an attending physician in the Department of Internal Medicine of Guangdong Maternal and Child Health Hospital, said, "The antiviral drug oseltamivir can be used under the guidance of a doctor. It is prime time to use it within 48 hours, which can shorten the course of disease and prevent the occurrence of severe diseases."
With the prevalence of various pathogens in the lower respiratory tract, Cen Zhenghui, deputy chief physician of Pediatrics of the Eighth Hospital affiliated to Guangzhou Medical University, pointed out that the general symptoms of influenza patients are more severe, with high fever obvious in the early stage of the disease, atypical respiratory symptoms, accompanied by fatigue, headache, muscle aches and other manifestations. Patients infected with mycoplasma pneumoniae, unlike influenza, are accompanied by typical symptoms of dry cough in addition to fever. In addition, influenza antigen, mycoplasma pneumoniae serum antibody detection, nucleic acid detection and other tests can help doctors make identification and diagnosis.
If the fever persists for more than 3 days or the cough is severe, you need to see a doctor.
On the second or third day of influenza infection, the immune cells in the body fight the virus with all their strength, and the human body may have repeated symptoms such as fever, headache, sore throat and runny nose. Mai Huachao suggested that at this time, you should rest at home and drink plenty of water to give your body the energy to fight the virus.
Generally, on the 4th day after infection, the body temperature gradually returns to normal, and symptoms such as sore throat, headache and runny nose begin to ease, but the cough will get worse. Mai Huachao pointed out: "When infants, especially those within three months, continue to have high fever for more than three days or cough is serious enough to affect rest, it is recommended to seek medical advice immediately."
After the fever has gone down, quite a few children will have cough symptoms. Mai Huachao said that if you have a dry cough, you can take some cough medicine. If you have a serious cough with phlegm, or have fever symptoms, you should seek medical advice in time. Most symptoms of influenza will be relieved within 3-7 days, but cough and physical recovery often take more than 1-2 weeks.
You can still get the flu vaccine after you get the flu.
Both influenza and mycoplasma pneumoniae can cause pneumonia. Cen Zhenghui pointed out that if the child has a fever for more than 3-5 days repeatedly, the high fever does not go away, or there is a severe cough, the doctor auscultates the rales in the lungs, and the chest film and other imaging findings suggest that the lungs are oozing, which may be pneumonia. The specific situation needs the doctor’s judgment.
Is it necessary to get a flu vaccine after being infected with the flu? Experts say that after the flu patients are cured, it is still necessary to vaccinate against different types of influenza virus infection. Although the protection of vaccine against influenza virus can not reach 100%, it can effectively reduce infection symptoms and improve recovery speed after vaccination. It is recommended to vaccinate after the fever is gone and the flu symptoms are basically relieved.
Hu Dandan, director of vaccination clinic for people with special needs in Guangdong Province of Guangzhou Women and Children Medical Center, said that usually, after 2-4 weeks of influenza vaccination, antibodies with protective level can be produced. Therefore, vaccination can have a protective effect when the peak of influenza comes in winter, and people aged 6 months and above can be vaccinated without vaccination contraindications.
