In the past week, the number of infected people in COVID-19 has increased significantly. According to the current clinical experience, most infected people have a course of about 7 days, and most of them recover after 3 days if they have fever symptoms. Those who have been vaccinated with COVID-19 vaccine and completed the intensive immunization have a shorter course of disease and a lighter condition. But after the nucleic acid or antigen test turns negative, some patients still have symptoms such as cough, sore throat, fatigue or loss of appetite. What should I do? Zhang Boli, an academician of China Academy of Engineering, answered this question.

"We found that some COVID-19-infected people still have some symptoms after rehabilitation in Wuhan, but with the weakening of the virulence of the virus, the probability of Omicron-infected people still having symptoms after the nucleic acid turns negative is lower, and the symptoms are lighter and easier to recover." Zhang Boli said that the experience of diagnosis and treatment in the past three years showed that the use of Chinese medicine, acupuncture, massage and traditional exercises can promote the recovery of patients and improve symptoms such as fatigue and shortness of breath. Taking active intervention measures can promote the physical and mental recovery of the cured person to a better state.

For the recovered patients who still have mild symptoms, Zhang Boli suggested that the body temperature should be kept normal after 2 days of negative nucleic acid, and the rest symptoms should be obviously relieved before returning to work and study. Elderly patients with basic diseases can rest for a few more days. If you really feel uncomfortable, you can also choose some targeted Chinese patent medicines.

For infected people who have no obvious symptoms and just recovered soon, Zhang Boli also reminded that Chinese medicine says "prevention after chi", that is, when the disease has just been cured, the vital qi in the body is still weak and the body function has not been fully recovered. At this time, we should also pay attention to the conditioning after illness, on the one hand, to consolidate the curative effect, on the other hand, to prevent the recurrence of the disease.

According to the article "Symptomatic Treatment and Self-care Methods for Mild Patients" published by Beijing Tiantan Hospital, the disease symptoms caused by Omicron mutant are mild, and the common main symptoms include fever, cough, fatigue, hypoesthesia, diarrhea, sore throat and myalgia. These symptoms appear alone, two or more in infected people, but most of them are mild and self-limited.

fever

stay in bed, drink plenty of water and eat light and digestible food.

For infectious fever, fever itself is one of the manifestations of the body's immune system to eliminate the source of infection. Unless there is high fever and the patient is seriously unwell, it is usually unnecessary to use antipyretics and other drugs in a hurry.

patients with high fever must be treated with cooling, and acetaminophen and ibuprofen are optional antipyretics. (However, only one antipyretic can be selected. Read the instructions carefully before use to avoid duplication and overdose; During taking acetaminophen, avoid drinking alcohol to prevent liver injury. )

Cough

The symptoms are not particularly serious, so you don't need to take cough medicine.

If the cough symptoms are very serious, and there is a tendency of dyspnea or affecting normal sleep and rest, you can take cough medicine for symptomatic treatment, including dextromethorphan hydrobromide tablets, dextromethorphan guaifenesin syrup, ambroxol hydrochloride tablets, acetylcysteine effervescent tablets, Lianhua Qingwen granules (capsules), Xuanfei Zhisou mixture, Jingyin granules, Tanreqing capsules and so on.

The incidence of sense of smell or taste loss

is not high, and most patients will gradually recover their sense of smell and taste in a week or so. This symptom is not unique to COVID-19, and other respiratory virus infections can also occur.

brush your teeth twice a day to ensure oral hygiene.

If possible, you can carry out olfactory training according to the recommendations of the World Health Organization, including smelling lemons, roses, cloves and eucalyptus twice a day for 2 seconds each time.

Try adding herbs and spices to food, such as pepper and lemon juice. However, for patients with diarrhea or gastrointestinal dysfunction, it is recommended to use it cautiously.

Diarrhea

Eat a light diet, and don't eat heavy oil, heavy salt and foods that are irritating to the gastrointestinal tract.

drink plenty of water and replenish lost water in time.

Patients with severe symptoms can use drugs such as montmorillonite powder and Huoxiang Zhengqi capsule (or pills, water and oral liquid) to relieve symptoms.

dry throat and muscle ache

listening to relaxing music or meditation can help relieve the pain.

Exercise moderately and drink plenty of water.

For joint, muscle or systemic pain, you can take over-the-counter analgesics such as acetaminophen or ibuprofen for treatment. Traditional Chinese medicine Shufeng Jiedu Capsule and Liushen Pill also have certain curative effects.
