Is there a "new strain" that causes dizziness recently? Multiple respiratory infections are prevalent! Experts warn →

The latest monitoring results from the Chinese Center for Disease Control and Prevention show that acute respiratory infectious diseases in my country are on the rise, with mycoplasma viruses, syncytial viruses, etc. still at high levels. At the same time, influenza has entered the seasonal epidemic period, and the influenza virus positivity rate has shown a clear upward trend, but is still lower than the same period last year.

Experts said that the peak season for influenza in northern my country is from November to March of the following year. Taking Beijing as an example, the peak season came later this year, and the epidemic season gradually began in December. Monitoring results show that the main strain of influenza A H1N1 is the main strain of influenza A H1N1.

Yan Weifeng, chief physician of the Department of Respiratory and Critical Care Medicine at Beijing Haidian Hospital: When the weather just turned cold, there was a large wave of mycoplasma. As we enter the flu season, especially after December, we will find that influenza has increased significantly. Now, influenza ranks first again. Although mycoplasma still exists, the incidence rate is indeed lower than before.

Doctors said that the main respiratory diseases currently prevalent include influenza, mycoplasma, chlamydia, rhinovirus, syncytial virus, human metapneumovirus, etc. These respiratory diseases may also be cross-infected, and it is not ruled out that a person may be infected with multiple respiratory diseases at the same time.

Yan Weifeng, chief physician of the Department of Respiratory and Critical Care Medicine at Beijing Haidian Hospital: There is no so-called mutual immune system, that is, if you have influenza, you can also get mycoplasma, and vice versa. Moreover, these two viruses are likely to overlap with each other, because whether we have influenza or mycoplasma, the protective ability of the respiratory tract will decrease.

According to experts, influenza is the only popular respiratory disease for which there is a vaccine. It is recommended that everyone get the influenza vaccine if conditions permit, especially the elderly, infants, pregnant women, patients with underlying diseases, obese people and other people with low immunity. Once infected with the influenza virus, they are more likely to develop pneumonia or related complications, and may also cause fluctuations in the condition of the original underlying disease and increase the possibility of hospitalization. It is recommended that these people get the influenza vaccine every year.

Is dizziness after getting the flu a "new strain"? Experts respond

Recently, some citizens reported that they felt dizzy after being infected with influenza. Is this a "new strain" of influenza? Relevant departments responded that no new strain of respiratory infectious diseases has been found so far.

Doctors said that different individuals have different symptoms when infected with respiratory viruses. Dizziness, headache, fatigue, muscle aches, etc. are all common symptoms of respiratory infectious diseases. These are systemic symptoms caused by the virus replicating in large quantities and spreading to various parts of the body through blood circulation. They are also a self-protection mechanism after the immune system recognizes the virus.

Yan Weifeng, chief physician of the Department of Respiratory and Critical Care Medicine at Beijing Haidian Hospital: The same pathogen may cause different symptoms in different people. For example, if one person has the flu, they may have more sore throat and runny nose, while another person may feel dizzy, have a sore throat, or have a more severe cough. So for everyone, even if it is the same pathogen, the clinical manifestations are different.

Doctors say that antiviral drugs for treating influenza are most effective when used within 48 hours of the onset of symptoms. Using antiviral drugs as early as possible can shorten the course of the disease and reduce the risk of developing severe illness and infecting people around you.

Citizens can also keep antipyretic and analgesic drugs at home. But do not use the medicine repeatedly. When using the medicine, be sure to read the instructions carefully and follow the doctor's advice.

If the patient has a persistent high fever, or has symptoms such as severe coughing, shortness of breath, and mental depression, and there is no improvement after 5 days of onset, complications and secondary infections may occur, and timely medical attention is required.

The recent trend of human metapneumovirus infection is on the rise

In addition to the increase in influenza patients, according to monitoring data from the Chinese Center for Disease Control and Prevention, the positive rate of human metapneumovirus in cases aged 14 years and below has shown a fluctuating upward trend in recent cases.

Human metapneumovirus is a common virus that can cause acute respiratory infections. The main symptoms are fever, cough, runny nose, etc., which are similar to influenza symptoms. The incubation period is generally 3-6 days, and the entire population is generally susceptible. At present, there is no vaccine or specific drug for human metapneumovirus, and the treatment measures are mostly symptomatic supportive treatment.

Doctors said that human metapneumovirus is more common in autumn and winter, and is less likely to cause severe illness, so people don't need to worry too much. Pay attention to washing hands frequently, wearing masks, and avoiding crowded or confined places can play an effective preventive effect.

Different respiratory diseases have different symptoms. How to treat them in a targeted manner?

What are the different symptoms of different respiratory infections? How can we judge? How to treat?

After the onset of influenza, respiratory symptoms such as fever, sore throat, and cough, as well as systemic symptoms such as headache and body aches often occur. The symptoms are more severe than other respiratory infections, and the course of the disease is generally 5 to 7 days.

After the onset of mycoplasma infection, the main symptom is cough, and the fever symptoms are often not obvious, or there is a low fever. The overall symptoms are relatively hidden. The course of the disease is more than two weeks, and in severe cases it can last for more than a month.

After the onset of infection with syncytial virus, rhinovirus, etc., the main symptoms are cough, sneezing, nasal congestion, fever, and sore throat. The symptoms usually improve after a week.

According to experts, these respiratory diseases can infect both adults and children, but the severity varies.

Yan Weifeng, chief physician of the Department of Respiratory and Critical Care Medicine at Beijing Haidian Hospital: From a clinical perspective, influenza is more severe than mycoplasma in adults, and influenza is more likely to cause severe symptoms; for children, mycoplasma is often not easy to recover, and more children develop severe mycoplasma, so influenza may be less severe in children. Adults and children are quite different.
