  Recently, all kinds of information about the prevention and control of the new coronavirus will always occupy a prominent position.

It also includes many new and old rumors, which may make everyone have a wrong understanding of the new crown, and use wrong methods in the process of preventing and treating the new crown.

  In this regard, Popular Science China has selected a batch of recent rumors that everyone has been most concerned about recently from the content of the new crown that has been refuted and popularized before, and analyzed them one by one, hoping to dispel everyone's concerns and review the correct new crown prevention and control methods.

01 These preventive methods are unfounded!

Can spicy food such as garlic prevent new coronavirus infection?

  There is no basis.

  In vitro experiments on allicin and related nutrients did show a certain inhibitory effect on pathogenic microorganisms, but it should be noted that these are mostly isolated and extracted allicin or alliin and other components, in vitro cell tests As a result, this is different from eating garlic every day.

  Judging from the current epidemic situation, there is no evidence that eating more garlic can prevent people from being infected with new coronary pneumonia.

Garlic has many health benefits, and moderate intake is good for health, but it is indeed "difficult for strong garlic" to prevent the new crown.

  The same goes for other green onions, ginger, peppers, and peppers.

Can drinking liquor prevent new coronavirus infection?

  Liquor does not have this function.

  Although 75% medical alcohol can be used to wipe the surface of objects to kill the new coronavirus, it is powerless to the virus that has entered the body, not to mention that almost all liquors do not have such a high alcohol content as medical alcohol.

Moreover, drinking itself may stimulate the human body, aggravate symptoms, and may affect the effect of medication. In addition, drinking is inherently harmful to health.

Can salt water gargle prevent new coronavirus infection?

  Salt water does not have this function.

  Zhong Nanshan's team refuted the rumors: Gargling with salt water is good for cleaning the mouth and throat, and it is helpful for pharyngitis.

However, the part that the new coronavirus invades is the respiratory tract, and gargling cannot clean the respiratory tract.

Secondly, there are currently no research results suggesting that salt water has a killing effect on the new coronavirus.

Can taking medicine prevent new crown?

  There is no such medicine.

  There is no drug that can clearly reduce the possibility of new crown infection. Whether it is the so-called new crown special medicine that is hot on the Internet, or cold medicine, it is impossible to prevent new crown virus infection by taking medication in advance.

In addition to wearing masks, washing hands frequently, ventilating at home frequently, and maintaining social distance and other protective measures, the correct way is to maintain a healthy diet, moderate exercise, and good sleep.

02 These operations are unnecessary!

Can masks be reused after cleaning?

  Can't.

  At present, both medical surgical masks and N95 protective masks are disposable products. After cleaning or disinfection, their protective performance may be reduced. Since viruses may be attached to masks that have been used for a period of time, they may also cause pollution during cleaning. .

Therefore, we need to replace new masks regularly, and if the mask is dirty or damaged, we must replace it at any time.

The new crown can cause hypoxia, should an oxygen generator be prepared at home?

  If the family does not need to inhale oxygen, there is no need to buy an oxygen generator to deal with the new crown.

  Oxygen inhalation therapy should be carried out under the guidance of a doctor. If the concentration is too high or the time is too long, it will lead to oxygen poisoning, so you must not judge by yourself.

  Oxygen inhalation for patients infected with the new coronavirus is also required depending on the condition. Asymptomatic and mild cases do not need oxygen inhalation, and ordinary cases need oxygen inhalation on demand; severe and critical cases require oxygen inhalation, but oxygen inhalation for patients infected with the new coronavirus is also auxiliary. Treatment needs to be used on the basis of combined treatment. To this extent, only oxygen inhalation at home is not useful.

  Instead of preparing an oxygen concentrator, it is better to prepare a finger-clip oximeter.

Listening to coughing can identify new coronavirus infection?

  Just kidding.

  A positive nucleic acid test for the new coronavirus is the gold standard for judging the infection of the new coronavirus.

Cough is just a symptom. Many diseases can cause cough, not necessarily caused by the new crown.

In addition, such small programs sometimes need to fill in personal information, which may cause sensitive information leakage, so everyone should be cautious.

Do you want to stock up on some antigen detection kits for regular testing to make sure you are not infected?

  no need.

  Antigen detection should be used to determine whether it is a new coronavirus infection after typical symptoms such as headache and fever have appeared. If no symptoms appear, regular antigen detection is not required.

Test once when you have symptoms, and 1-2 times during the course of illness. Considering that even repeated infections usually have to be separated by several months, in fact, as long as we always have 2-3 antigen detection kits per person, there will be no problem. , There is no need to buy dozens of people at a time.

Infected with the new crown virus, how many medicines can you take to get better faster?

  mistake.

  This practice can be life threatening.

Each drug has a strict usage and dosage. Only by using the correct drug can it cure the disease and cause fewer side effects.

Taking multiple drugs without authorization can easily lead to repeated drug use, overdose, and endanger human health.

Although some drugs have different trade names, their chemical composition is the same, and they still belong to the same drug. If they are used in combination at will, it is very easy to cause excessive doses of drugs and cause danger.

  Therefore, there are doctor's orders and prescriptions, and you must take the medicine according to the doctor's advice, and you can't add medicine at will.

For mild patients treated at home, it is recommended to follow the guidelines of the National Health and Medical Commission for home treatment.

Read the instructions carefully before taking the medicine, and don't take several medicines at once.

03 These scapegoats are not covered by masks!

Wearing a face mask causes lung nodules, which turn into lung cancer?

  Wear it with confidence.

  Many people have lung nodules, and the increase in the detection of lung nodules is mainly due to more advanced detection methods and more frequent screening, but it has nothing to do with masks.

Moreover, in most cases, "lung nodules ≠ lung cancer", there is no need to be too anxious.

Wearing a mask correctly is still one of the effective ways to resist the new coronavirus.

Does wearing a mask cause hypoxia?

  According to the situation.

  For healthy ordinary people, experiments have shown that even wearing a 7-layer medical surgical mask, blood oxygen saturation is minimally affected.

N95 or masks with higher protective performance are more suitable for professionals in high-risk environments, or ordinary people who need to go to the hospital to wear temporarily, because wearing N95 masks for a long time may cause discomfort.

  In addition, people who are already prone to breathing difficulties, such as smokers, emphysema patients, and obese people, wearing N95 masks may make things worse and even aggravate breathing problems.

Mask contains graphene, harmful to human health?

  fake.

  The so-called "graphene masks" currently on the market are mostly gimmicks. For example, a certain "biomass graphene" raw material has been verified to be processed from straw.

It is worth noting that some mask materials use nano-scale activated carbon, and long-term wearing of activated carbon masks does have the risk of inhaling particles.

For daily epidemic prevention, the public should choose protective masks that meet the national standards, and do not choose gimmick products.

  Masks contain ethylene oxide, will wearing them cause cancer?

  don’t worry.

  Ethylene oxide is a common and easy-to-use disinfectant that can be used for low-temperature sterilization. Food packaging, baby diapers, sanitary napkins, masks, etc., can all be sterilized with ethylene oxide.

Ethylene oxide itself is volatile. Masks are sterilized with ethylene oxide. After disinfection, they will be allowed to stand for a period of time to dissipate according to regulations. Only when the detected content reaches a safe range can they be sold on the market. Therefore, there is no need to worry about buying qualified masks.

04 These worries are unnecessary!

If you have a fever, you are infected with the new coronavirus

?

  Not necessarily.

  Fever is only a symptom, not a diagnosis of a disease. You cannot judge what kind of disease you have just by having a fever. Therefore, it is impossible to diagnose the new crown based on the symptom of "fever".

The diagnosis and treatment plan also stated that a diagnosis should be made "based on a comprehensive analysis of epidemiological history, clinical manifestations, and laboratory tests. A positive nucleic acid test for the new coronavirus is the primary criterion for diagnosis."

Eating tangerines, oranges and other fruits will lead to a positive antigen test?

  Very unlikely.

  If the antigen detection is done correctly, the sampling site is the nasal mucosa, even if you eat oranges, it will not come into contact with orange juice, so there is no effect.

However, orange juice can make the antigen test positive, because it destroys the suitable pH environment, but this itself does not meet the sampling standards, the result is meaningless, and it does not mean that the antigen test is inaccurate.

The strain prevalent in Beijing is more virulent than the strain in Guangzhou, so it is more uncomfortable?

  it's not true.

  Whether it is uncomfortable or not is mainly a personal feeling.

In fact, the BF.7 mutant strain popular in Beijing and the BA.5.2 mutant strain popular in Guangzhou are both branches of Omicron, and their infectivity and pathogenicity will not change substantially.

As for individual symptoms, this may be related to factors such as physical fitness, age, and whether there are underlying diseases.

Sooner or later everyone will have yang, so it is better to get infected earlier.

  Don't try.

  After being infected with the new coronavirus, you will gain immunity against the strain within a certain period of time, but it does not mean that you will not be infected again.

Omicron was more likely to cause reinfection than Delta and previous variants.

In addition, repeated infection still has a certain risk of severe disease, which will be transmitted to high-risk groups such as the elderly at home and those with underlying diseases.

Therefore, we still need to pay attention to personal protection and get vaccinated in time.

Are the sequelae of the new crown very serious?

  Not so.

  Tong Zhaohui, an expert in respiratory critical care, said that the current research on symptoms after the new crown is aimed at the previous strains.

At present, it should be said that there is no observation of Omicron's symptoms after the new crown in China.

However, more than 90% of Omicron is asymptomatic and mild, and its symptoms are mainly manifested in the upper respiratory tract, such as low-to-moderate fever, cough, and sore throat. It will be fine in 5 or 7 days.

  From a common sense point of view, there should be no sequelae, because it is in the upper respiratory tract and has not affected the organs and tissues in our body. At least there is no relevant literature at home and abroad to support this statement.
