What to do if there is superinfection? Do I need infusion if I have a fever?Experts’ detailed explanation


Currently, as winter begins in various places, respiratory diseases have entered a period of high incidence. How should we prevent and treat it? What are the misunderstandings about respiratory diseases?

The “Healthy China” column of the main station invited Professor Zhang Wenhong of Huashan Hospital Affiliated to Fudan University, Liu Qingquan, President of Beijing Hospital of Traditional Chinese Medicine Affiliated to Capital Medical University, and Tong Tong, Vice President of Beijing Chaoyang Hospital Affiliated to Capital Medical University and Director of the Beijing Institute of Respiratory Diseases. Three experts from Zhaohui explain in detail the common misunderstandings about respiratory diseases on the Internet.

Myth 1: Respiratory viruses this winter are complicated

Is superinfection terrible?

Zhang Wenhong said that many people are afraid of superinfection. In fact, sometimes multiple viruses or bacteria are detected because very sensitive detection methods are used, so don’t worry too much.

Tong Zhaohui said that although many pathogens have been detected, it does not mean that every one is pathogenic. The doctor will comprehensively analyze which bacteria are the patient’s pathogenic bacteria based on the patient’s clinical condition.

Liu Qingquan said that from the perspective of traditional Chinese medicine, superinfection is a combined disease or comorbidity. “For example, after having a fever for 7 days, it was discovered that it was influenza. About 10 days later, the fever returned, and this time it was mycoplasma. This is actually not a superposition, but a result of poor maintenance and subsequent illness.”

Myth 2: Mycoplasma pneumonia is a mutation of the new coronavirus?

Tong Zhaohui said that humans discovered the microorganism Mycoplasma at the beginning of the 20th century, and it was not determined to be a pathogen until the end of the 20th century. The new coronavirus was only known to everyone at the end of 2019, and the two have nothing to do with each other.

Why are children particularly susceptible to mycoplasma infections? Tong Zhaohui said that children’s immune systems are not fully developed and their resistance is not as good as adults’, so they are more susceptible to infection.

Misunderstanding 3: Once you have a cold or fever, you need to get an infusion immediately?

Tong Zhaohui said, “Infusions can heal a cold and fever quickly.” This is actually a misunderstanding.

Compared with the flu, a cold has a lower fever and milder symptoms, often affecting the upper respiratory tract. If you have a fever or cough after catching a cold, just take fever-reducing or cough-relieving medicine at home. Pay attention to getting more rest, drinking more water, and supplementing your nutrition.

As for influenza, some influenza may cause pneumonia or even severe pneumonia. At this time, you may need to be hospitalized, and the resident doctor will determine whether you need infusion.

Zhang Wenhong also said that infusion is generally limited to hospitalized critically ill patients, or some drugs cannot be taken orally and can only be administered through infusion. For the common cold, oral medications work better.

Myth 4: Mycoplasma pneumonia can be cured at home?

Tong Zhaohui said that in most cases, whether it is a virus or mycoplasma, if it is limited to the upper respiratory tract, most of it can heal on its own, and a small number may develop pneumonia.

Zhang Wenhong said that generally speaking, mycoplasma pneumonia can be improved with some symptomatic drugs at home, but it is necessary to pay attention to whether it develops into a serious condition. For example, if your child’s condition improves after taking medicine, you can observe it at home; if your child still has a high fever after taking antipyretics and is sluggish and unwilling to eat, you should seek medical attention as soon as possible.

Misunderstanding 5: Increase exercise in winter

Can you improve your immunity by sweating profusely?

Liu Qingquan said that from the perspective of traditional Chinese medicine, excessive sweating will damage a person’s yang energy. During winter sports, your body will feel slightly warm and you may sweat a little. It’s okay to work up a sweat, but it doesn’t have to be every day.

Zhang Wenhong said that everyone is encouraged to maintain a certain level of exercise. “Even if it’s a busy day, it’s good to take 5,000 steps.”

Special reminder: Please pay attention to weather conditions in winter and wear a mask as appropriate.
