How to deal with mixed infection with multiple pathogens

How to deal with mixed infection with multiple pathogens

On January 14, the National Health Commission held a press conference and invited relevant experts to introduce the prevention and treatment of respiratory diseases and health tips in winter in my country.

“This winter and next spring, China will continue to see alternating or co-epidemic trends of multiple respiratory pathogens, and influenza viruses will still be the dominant ones in the short term.” Wang Dayan, director of the National Influenza Center of the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention, said that the continued impact of the JN.1 mutant strain Affected by multiple factors such as importation, gradual decline in domestic influenza activity, and declining population immunity levels, the epidemic of new coronavirus infections may rebound this month.

At the same time, influenza B virus infections are on the rise overall. Data show that the proportion of influenza B virus infections in southern provinces has continued to rise to 36.8% in the past three weeks, and the proportion of influenza B virus infections in northern provinces has continued to rise to 57.7% in the past five weeks. In some provinces, the proportion of influenza B virus infections has exceeded Influenza A virus infection.

So, will mixed infections or repeated infections occur with multiple pathogens? Will it induce cardiovascular diseases such as myocarditis? How to deal with the co-epidemic situation of multiple respiratory pathogens and effectively avoid infection or worsening of the disease? Experts interpreted these issues.

There is no cross-immunity between different pathogens

“After infection with influenza A virus, influenza B virus, new coronavirus, respiratory syncytial virus, mycoplasma and other pathogens, the immunity established by the body is not long-lasting, so repeated infections will occur.” Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital Explain, and there is no cross-immunity between these pathogens, which means that the body’s immunity stimulated by infection with one pathogen has no cross-protective effect on other pathogens, so simultaneous or alternate infections by different pathogens will exist.

Wang Guiqiang reminded that infections by different pathogens may aggravate the condition, and are particularly likely to damage the upper respiratory tract mucosal barrier, which can then induce bacterial infections. Therefore, susceptible groups, vulnerable groups, and patients with underlying diseases must attach great importance to it and seek medical treatment in a timely manner.

So, how to protect yourself to effectively avoid infection?

“Traditional Chinese medicine teaches that ‘where evil gathers, the qi will be deficient’, so protecting and maintaining righteousness is the key to preventing recurring attacks.” Liu Qingquan, president of Beijing Hospital of Traditional Chinese Medicine, reminded that regular sleep and a light diet are very important to strengthen righteousness. If you are sick, be sure not to blindly use medication. The overlapping use of Western medicine and traditional Chinese medicine is not only detrimental to rapid recovery, but may even cause side effects.

Wang Guiqiang suggested that during a period when respiratory infectious diseases are more common, the public should take personal protection. Protective measures include minimizing going out as much as possible, avoiding crowded places, wearing a mask when going out, maintaining hand hygiene, and getting vaccinated. If symptoms such as fever occur, pathogen detection should be carried out in time to carry out targeted treatment. Especially people with underlying respiratory diseases should seek medical treatment in time to effectively control the original underlying diseases while avoiding concurrent infections that may lead to worsening of the condition.

  These groups should be protected against cardiovascular disease risks

Recently, news that people suffering from myocarditis due to influenza may cause arrhythmia have attracted attention. So, will respiratory infections have any impact on the cardiovascular system?

“Whether it is bacterial infection, viral infection or mycoplasma infection, these respiratory diseases will affect cardiovascular health.” Liu Qingquan reminded that if the fever, cough and other symptoms have improved, but there is still chest tightness and shortness of breath, lower limb edema, and even half-way sleep, Lying down, this indicates that signs of cardiovascular disease have appeared, and you need to seek medical treatment as soon as possible.

“At present, from an epidemiological point of view, there is no data to support the claim that young people have a higher incidence of cardiovascular disease. Existing data show that the probability of sudden death from cardiovascular disease is higher in men than in women, and the older the age, the higher the risk.” Liu Qingquan introduced that the number of cardiovascular diseases among young people is gradually increasing, among which obesity, hyperlipidemia, hyperglycemia, and high uric acid are more common. In addition, busy work makes it easy to neglect one’s own health, which may cause delays in disease progression and lead to risks. Increase.

People who have not been diagnosed with cardiovascular disease can perform self-screening. Liu Qingquan said that risk factors for cardiovascular disease include overweight, obesity, high-salt diet, smoking, excessive drinking, hyperlipidemia, high blood pressure, high blood sugar, high uric acid, and high homocysteine, especially those with a family history of cardiovascular disease. People should be more vigilant.
