As the first batch of friends who were infected with the new crown virus gradually became “healthy”, a series of questions about recovery began to arise. Accompanying the emergence of the “Yangkang Tide”, there are still many rumors that are difficult to distinguish between true and false.
We have sorted out some common problems after turning negative, hoping to give some help to friends who have recovered.
From “Yang” to “Yangkang”
How do I know if I’m still contagious?
Generally speaking, asymptomatic infected persons can end the isolation 10 days after the first positive antigen/nucleic acid test , that is, they are no longer infectious;
Most infected people with mild to moderate symptoms are no longer contagious 10 to 14 days after the onset of symptoms and do not need to be isolated.
However, if the above-mentioned isolation time cannot be achieved, two nucleic acid tests can be negative (with an interval of 24 hours or more), or the antigen is negative for 3 consecutive days , so that the infectivity is also very low. Return to normal activities.
How to disinfect the home after turning overcast?
Generally speaking, it is enough to do normal daily cleaning, and there is no need to deliberately disinfect .
Several studies have shown that for a typical indoor environment, the level of the new coronavirus can be reduced by 99% within 3 days on most non-porous surfaces.
Moreover, the risk of virus transmission through the surface of objects to the mouth, nose, and eyes is low, and daily cleaning is enough to reduce the risk of infection.
It is even more unnecessary to disinfect the air with disinfectants .
First of all, most “spray” disinfectants cannot effectively disinfect the air outside the droplets; secondly, using “spray” for disinfection also has the risk of triggering asthma.
To “disinfect” the air, as long as the daily ventilation of the room is done well, the virus content in the air can be effectively reduced.
If someone in your family is lucky enough not to be infected, you can perform a simple disinfection on high-touch surfaces (such as doorknobs, toilet flush buttons, etc.) for peace of mind . Wipe these places with 75% alcohol wipes, and do a good job of daily ventilation.

As for the toothbrush…you can get a new one if you want one. If you can’t buy a new one in a short time, then continue to brush your teeth with the old toothbrush. An old toothbrush won’t make you “rejuvenate”, but not brushing your teeth will make you develop dental caries.
Health problems after “Yang Kang”
What should I do if I have abnormal sense of smell and taste after turning overcast?
In most cases, these problems resolve on their own within a few weeks . According to research data, the recovery rate of these paresthesias caused by the new crown infection within a month is about 70% to 80%.
However, a small number of people do have abnormal smell/taste that persists for several months or longer. These paresthesias are also one of the symptoms of “new crown”.
There are currently no good medical treatments for these abnormalities, but olfactory training with strong-smelling things such as coffee, perfume, and citrus may help .
In addition, pay special attention to safety when you lose your sense of smell, because it is difficult for people to detect dangers such as gas leaks and food deterioration.

What should I do if I still have symptoms such as coughing and lack of strength after turning negative?
The cough after turning negative may last for several weeks. There is currently no targeted treatment, and the same relief method as during the positive period can still be used ( click here to see the precautions for new crown medication).
If the cough persists for more than 8 weeks, or symptoms such as purulent sputum, hemoptysis, or dyspnea occur at the same time, it is recommended to see a doctor to rule out other diseases.
For the fatigue after “Yangkang”, the current mechanism and treatment methods are still unclear.
The focus of treatment is to control fatigue symptoms , such as gradually returning to daily life and work, setting a schedule in advance, scheduling important things at a time when you are expected to have the most energy, and setting aside small breaks between jobs.
Some people say that antibodies can be produced only 15 days after turning negative. During these 15 days, people can easily be infected with the new coronavirus again. Is it true?
This is completely wrong. Within 15 days after turning negative, the human body not only has antibodies, but also has immunity to the new coronavirus .
Generally speaking, the human body begins to produce antibodies on the 7th day after exposure to the new coronavirus. At this time, the infected person is still in the symptomatic period, and the symptoms have only appeared for a day or two.
About 10 to 20 days after the onset of symptoms, the antibody levels of IgM and IgG will gradually reach their peak. At this time, the person is in the stage where the symptoms are getting better, but there is no “Yangkang”.
By the time it is truly “Yangkang”, the antibody level has already reached its peak. Within 15 days after “Yangkang”, the antibody level is still at the peak, and people’s immunity and resistance to the new coronavirus are very strong.
As time goes by, the antibody level will gradually decrease, and the body’s immunity to the new coronavirus will also gradually decrease.
In any case, within 15 days after “Yangkang”, people are not in a susceptible period, but are not easily infected with the new coronavirus.
return to normal life
Can I participate in sports after turning negative?
Before gradually resuming sports, it is recommended that asymptomatic infected persons rest for at least 10 days after they are found to be positive;
Those with mild infection symptoms should rest for at least 10 days after the onset of symptoms and at least 7 days after the symptoms disappear ;
People with severe symptoms, underlying diseases, or previous cardiopulmonary symptoms need to get permission from a doctor .
In addition, for the health of others, please confirm that you have turned negative before participating in group sports .

In the recovery process, start with short-term low-intensity exercise and gradually increase the amount .
If the following symptoms appear, you need to stop exercising for at least 1 to 2 days before restarting: the degree of fatigue or muscle soreness is significantly higher than before the infection, the quality of sleep is reduced, and the resting heart rate increases by more than 10 beats per minute the next morning after exercise.
In order to avoid serious cardiopulmonary injury, if the following danger signs appear during the resumption of exercise, you need to stop exercising immediately and see a doctor if necessary: chest pain, obvious palpitations or rapid heartbeat, dyspnea that does not match the exercise intensity, leg swelling, etc. .
What are the possible long-term effects of being infected with the new crown?
Regarding the long-term impact of infection with the new crown, the definition needs to meet 3 points:
1. Have been diagnosed with the new crown;
2. The relevant symptoms occurred within 3 months after the onset of the new crown infection, and the symptoms and effects lasted for at least 2 months;
3. These symptoms cannot be explained by other diagnoses (relevant examinations under the guidance of a doctor are required to exclude other diseases).
The most common long-term symptoms of COVID-19 include: fatigue, shortness of breath or difficulty breathing, problems with memory, concentration or sleeping, persistent cough, problems with smell or taste, chest pain, muscle pain, depression or anxiety, and fever.
Data from the World Health Organization suggest that about 10% to 20% of people with COVID-19 experience persistent symptoms that could be long-term effects .
However, it is currently medically difficult to predict whether a specific infected person will have long-term effects and the specific duration, and there is no specific treatment for it. To prevent the long-term effects of the new crown, we can only try to avoid infection .
However, data suggest that patients improve over time and that holistic treatment, including rehabilitation, may be effective in improving long-term symptoms.
After recovering from the new crown, masks are still required to be worn in public places 丨 Tuchong Creative
I have been infected with the new coronavirus, do I still need to be vaccinated?
need to fight .
At present, according to domestic regulations, the new crown vaccine can be vaccinated after half a year after turning negative . All commercially available vaccines can be used for a second booster dose. Just choose the vaccine that is available to you.
Vaccination is to reduce the risk of “reinfection”, critical illness and death.
Patients who have just recovered from a positive test usually have some immunity. Most people do not get reinfected in the short term.
However, over time, antibodies in the human body will decline, virus mutations may also cause immune escape, and the risk of repeated infection will increase.
After receiving a booster vaccine at the right time, the antibody level against the new coronavirus can be increased, and the risk of critical illness or even death can be significantly reduced .
