　　At present, the goal of the prevention and control of the new crown pneumonia epidemic is to protect health and prevent severe illness.

After being infected with the new coronavirus, how to take medicine scientifically?

After recovery, what are the precautions?

How long can I exercise?

Does blood donation increase the risk of infection for people who are not infected with the new coronavirus?

In response to the current hot issues of public concern, the Joint Prevention and Control Mechanism of the State Council organized authoritative experts in related fields to answer them.

How to use medicine scientifically after infection?

　　Gao Yan, Director of the Department of Infectious Diseases at Peking University People's Hospital, said that after being infected with the new coronavirus, clinical symptoms such as high fever appear. When the body temperature exceeds 38.5 degrees Celsius, the human body will feel very uncomfortable. At this time, some antipyretic drugs are needed.

　　Gao Yan introduced that if the patient has some chronic diseases, such as gastric ulcer, duodenal ulcer, or some basic diseases of the gastrointestinal tract, when taking antipyretic and analgesic drugs, do not take them on an empty stomach.

In addition, intensive medication may induce symptoms such as gastrointestinal bleeding. It is safer to use some protective agents for gastric mucosa and then take antipyretic and analgesic drugs.

　　"For most patients with new crowns, mild symptoms are still the main symptom, and symptomatic treatment is enough. Cough-relieving, cough-relieving, and phlegm-reducing drugs are relatively safe." Gao Yan reminded that there may be differences between many drugs in clinical practice. Some interactions, especially those with some serious chronic underlying diseases, should be used under the guidance of medical institutions and doctors.

What should I pay attention to after recovery?

　　Liu Qingquan, director of the Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University, said that 7 to 10 days after being infected with the new coronavirus, most people will enter a state of recovery. The nucleic acid or antigen may be negative, but some symptoms will still remain, such as cough, Sore throat etc.

Entering the recovery period, the patient must maintain a high morale mentally.

　　Liu Qingquan reminded that after recovery, do not eat or drink too much, but maintain a light diet, strengthen nutrition, take in enough protein, and eat more vegetables and fruits to ensure physical recovery.

At the same time, the pace of life and work should be appropriately slowed down, and don't stay up late.

　　For some people who have returned to work one after another after recovery, Gao Yan said that if their physical strength has improved significantly after the fever subsides, they can return to work.

However, some respiratory symptoms may recover more slowly, and you should stay in bed more during the febrile period.

How soon can I exercise after recovery?

　　Liu Qingquan reminded that moderate exercise is beneficial to restore health, but not strenuous exercise. Excessive exercise will not only fail to restore health, but may cause some other problems.

　　Liu Qingquan said that you can choose an appropriate amount of exercise according to your own exercise habits, no more than one-third of the usual amount of exercise, and you can gradually increase it.

　　Gao Yan said that for young and middle-aged groups, the process of entering the recovery period will be shorter, and it will not affect the resumption of work and production.

But for high-intensity fitness exercises, you still need to slow down a little bit, pay attention to rest, strengthen nutrition, and let yourself return to a normal state as soon as possible.

　　"For the elderly over 60 years old, especially those with chronic diseases such as diabetes, high blood pressure, and coronary heart disease, they should pay more attention to respiratory symptoms, such as cough, chest tightness, shortness of breath and other symptoms." Gao Yan introduced After the nucleic acid or antigen turns negative in about a week, these respiratory symptoms may continue. After the condition is obviously relieved, it is more conducive to health to resume normal exercise.

Will donating blood increase the risk of infection for people who have not been infected with the new crown?

　　"A healthy adult's blood donation does not exceed 13% of his total blood volume, and has no adverse effects on the body." Guo Jin, deputy chief technician of the Beijing Red Cross Blood Center, introduced that the total blood volume of a healthy adult accounts for about 8% of body weight. For example, if a person with a weight of 50 kg donates 200 or 400 ml of blood, which accounts for 5% or 10% of his total blood volume, the proportion of people with a heavier body weight will be even lower.

　　Guo Jin said that blood donation is the collection of peripheral blood from the human body. After blood donation, the blood in the liver, spleen, lungs and other blood storage organs will be quickly replenished into the peripheral blood to restore the circulating blood volume.

Donating blood does not affect health and does not increase the risk of contracting the new coronavirus.

What are the conditions to donate blood after being infected with the new crown?

Is donated blood safe?

　　Guo Jin introduced that for asymptomatic, mild and common infected people who have been infected with the new coronavirus, one week after the symptoms of upper respiratory tract infection such as fever, cough, and sore throat have completely disappeared, and seven days after the last nucleic acid or antigen test is positive, they can donate blood .

If it is a severe or critical infection, it needs to be 6 months after recovery before donating blood.

　　"This standard is consistent with the international requirements for delaying blood donation after infection with the new coronavirus, as well as the current requirements for delaying blood donation for patients with respiratory infections and lung infections, and will not cause harm to the health of blood donors," Guo Jin said.

　　In response to the question of whether the blood donated by blood donors who have been infected with the new coronavirus is safe, Guo Jin said that the new coronavirus is a respiratory virus and will not be transmitted by blood transfusion.

So far, there are no reports of the spread of the new coronavirus through blood transfusions in the world.

The blood donated by blood donors who have recovered from COVID-19 infection is safe. Blood banks will strictly manage the collection and supply of blood to ensure that the infected person recovers and donates blood after a period of health observation.
