Fever, headache, muscle pain beware of swine flu. Under what circumstances do you need to see a doctor? The doctor said so.

Every year, at the turn of winter and spring, there is a high incidence of respiratory diseases, especially influenza. Many people find that there are more and more people suffering from H1N1 (influenza A). How should they be treated symptomatically once they are infected with H1N1? There is a slight increase in the number of patients with swine flu but no severe illness as the first line of defense to protect the health of the citizens. At present, there is a slight increase in the number of febrile patients who come to see a doctor. At present, there is no occurrence of severe cases caused by influenza. Liu Hongyan, director of the infection department of Shenyang sixth people's Hospital, told reporters that because oseltamivir is used for drug prevention, it is effective only during medication. People with poor immunity are best prevented by influenza vaccination, but susceptible people who have not been vaccinated during the influenza epidemic can still be vaccinated in time. A very small number of people, especially children, will still be infected after being vaccinated with influenza in autumn and winter. Vaccination is not 100% guaranteed to avoid infection.

Every year, at the turn of winter and spring, there is a high incidence of respiratory diseases, especially influenza. Recently, many people have found that more and more people are suffering from swine flu (influenza A), and many parents also say that the number of children with fever in kindergartens is increasing. So, once infected with swine flu, how should it be treated symptomatically? Under what circumstances do you need to see a doctor? The reporter interviewed the doctor of the sixth people's Hospital of Shenyang.

Song Xiaodan, director of emergency department: there is a slight increase in the number of patients with H1N1, but there is no serious disease.

As the first line of defense to protect the health of the public, the emergency departments of major hospitals are the "outposts" that can best reflect the incidence of the population. Song Xiaodan, director of the emergency department of Shenyang sixth people's Hospital, said in an interview with reporters that there is a slight increase in the number of fever patients, but there will not be a pandemic at present. "Winter and spring is the season with high incidence of influenza. It is usually before December to March of the following year, but the occurrence of influenza this year lags slightly behind."

In recent days, most of the H1N1 patients who come to the emergency departments of the six hospitals are young and middle-aged. "several young people in their 20s came to the emergency room for medical treatment because of high fever, but there were no serious complications and all recovered after reducing the fever." Song Xiaodan said that at present, there are no severe cases caused by influenza. "for healthy adults, influenza is a self-limited disease." It should be noted that there is no specific cure for viral infection, but symptomatic support treatment, such as ensuring nutrition, taking some analgesic drugs, fever can be targeted for antipyretic, and so on, which generally heal in about a week. "

Liu Hongyan, director of the first infection department: influenza vaccine can be injected during the epidemic period

Liu Hongyan, director of the infection Department of the sixth people's Hospital in Shenyang, told reporters that the main strain of H1N1 virus prevalent this year is Type A H1N1. "this strain is not new, it has also been prevalent in previous years, and this strain is covered by the influenza vaccine we get every year. At present, vaccination is the best form of prevention. Because oseltamivir for drug prophylaxis is effective only during medication, there is no protective effect after withdrawal, and long-term use of this drug is not recommended, people with poor immunity are best prevented by influenza vaccination. "

Although influenza vaccines are often injected in autumn and winter, vulnerable people who have not been vaccinated during the influenza epidemic can still be vaccinated in time. It is worth noting that a very small number of people, especially children, will still be infected after being vaccinated with influenza in autumn and winter. In this regard, Liu Hongyan explained that vaccination is not 100% guaranteed to avoid infection, but can greatly reduce the risk of severe illness.

So, how to tell the difference between the common cold and the flu? Liu Hongyan said: "the common cold is mainly respiratory symptoms, systemic symptoms are relatively mild." Flu has severe systemic symptoms, such as high fever, headache, muscle pain and so on. " Liu Hongyan warned that although influenza can heal itself, it may still lead to pneumonia, myocarditis, otitis media and other complications, so we should not take it lightly. At present, although the weather is getting warmer, it is very necessary to wear a good mask and wash hands frequently. Good self-protection can avoid infection to a large extent. Will you be infected again when you go to work or school after recovering from H1N1 infection? "the immune protection period after a flu is about half a year, so as long as you recover, you don't have to worry about reinfection at all." Liu Hongyan said.

Liu Che, deputy director of the laboratory department: at present, the positive rate of H1N1 is relatively high.

In the laboratory of the laboratory of the sixth Hospital, Liu Che, deputy director of the laboratory, was busy nervously. He said that at present, there are more influenza tests than before. "We are talking about influenza virus detection, the full name is H1N1 and syncytial virus nucleic acid detection, and samples are usually collected by pharynx swabs. The swabs collected will be sent to the laboratory and tested by PCR. Judging from the results of the samples recently received, the current positive rate of H1N1 is still very high. "

"through timely influenza virus testing, patients can quickly know whether they are infected with influenza A, so as to treat the symptoms." Liu Xin said that if the specimens sent before 11:30 on a working day, the results can be detected on the same day, and the samples after 11:30 will report the results before 11:30 the next day. "everyone can take targeted drugs, if they are not suffering from the flu." there is also a need for further examination, can not blindly use antiviral drugs. "

Liu Xin reminded that winter and spring is the epidemic season of a variety of respiratory viruses, in addition to influenza viruses, there are many viruses may cause symptoms similar to influenza, so timely detection is very necessary. "in addition to detecting influenza viruses, six respiratory tests can also be carried out, including human metapneumonia virus, adenovirus, respiratory syncytial virus and parainfluenza 1, 2 and 3 viruses. Early and rapid detection of respiratory viruses can identify the cause, help to judge the prognosis, predict the severity of the disease, and accurately use drugs. " Liu Xin said.
