How is influenza A different from the common cold? Will influenza A and new crown superimpose infection? Learn together→
Every spring is the season of high incidence of influenza A.
Surveillance data show that the level of flu activity, mainly influenza A, has continued to rise recently. What are the symptoms of influenza A infection?
How is influenza A different from the common cold?
The National Health Commission recently invited experts in related fields to clarify doubts.
According to experts, influenza A is an acute upper respiratory infectious disease caused by influenza A virus. The main symptoms are fever, headache, muscle and joint pain, and general discomfort. Some of them also manifest as sore throat, runny nose, vomiting and diarrhea. Pneumonia can also occur.
A stream is mainly transmitted through respiratory droplets, and the crowd is generally susceptible.
Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital:
We emphasize that the elderly and children should pay special attention, because according to the current global data, children and infants tend to become heavier after getting the flu, and are prone to flu pneumonia and other symptoms.
Another is the elderly over the age of 65. On the one hand, the probability of influenza pneumonia will increase after he has the flu.
What's the difference between the flu and the common cold?
Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital:
Of course the flu is more serious, with fever, headache, muscle and joint pain.
The common cold is mainly catarrhal symptoms of the upper respiratory tract, such as runny nose and cough, which will be cured soon, so from the perspective of the course of the disease, the course of severe flu may be 5 to 7 days, and the common cold usually lasts for three to five days. The day is over.
Tong Zhaohui, director of the Beijing Institute of Respiratory Diseases:
If your body temperature is above 39 degrees and you have severe systemic symptoms, such as fever and discomfort, or even worsening cough and shortness of breath, you should go to the hospital in time.
Is this year's A flow more severe than previous years' symptoms?
Winter and spring are seasons of high incidence of many respiratory infectious diseases.
Why do people generally feel that the symptoms of this wave of H1N1 flu this year are more serious than previous years?
Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital:
In fact, the reason for this is that part of the flu itself is relatively serious. It turns out that people have not paid enough attention to it.
The second possible reason is that when we fought against the new crown epidemic in the past three years, everyone has been very well protected. Most people have basically not been infected with the influenza virus in the past three years. Twenty to thirty people have been infected with influenza, and they have been infected one after another. He has a certain degree of immunity, and his symptoms are not severe when he is infected with influenza again. Therefore, in the past three years, all of us have been susceptible to influenza, and Many people have not been infected for three years, so re-infection is easy to become serious.
According to experts, influenza emphasizes symptomatic and supportive treatment, and patients with severe symptoms or those at high risk of severe illness can receive antiviral treatment.
Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital:
Our country now has 6 kinds of antiviral drugs against influenza, including oral and intravenous, so the choice of these drugs should be used under the guidance of a doctor.
Is it possible to superimpose infection with influenza A and new crown?
Many people have doubts, is it possible to superimpose infection with influenza A and new crown?
Experts said that influenza A and the new crown are both respiratory infectious diseases. It is currently the flu season, and theoretically, superimposed infection 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.
Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital:
If you do not take good protection, you may be infected at the same time or sequentially. But now we are testing like fever clinics. We also test for influenza and new crowns. Currently, new crowns The detection did not find.
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 hope that everyone will continue to maintain the good hygiene habits we have developed in the prevention and control of the new crown.
One is 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.
