Recently, all kinds of information about prevention and control in Covid-19 always occupy a prominent position. There are also many old and new rumors, which may make people have a wrong understanding of COVID-19 and adopt the wrong means in the process of preventing and treating COVID-19.
Don’t believe these 18 rumors about the epidemic!
01
These preventive methods are unfounded!
Spicy food such as garlic can prevent Covid-19 infection?
There is no basis.
Allicin and its related nutrients did show a certain inhibitory effect on pathogenic microorganisms in vitro experiments, but it should be noted that,These are mostly the results of cell tests in vitro for components such as allicin or allicin, which are 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 COVID-19. Garlic has many health effects, and moderate intake is beneficial to health, but it is really difficult to prevent COVID-19.
Other onions, ginger, peppers and peppers are the same.
Can drinking white wine prevent Covid-19 infection?
Liquor does not have this function.
Although 75% of medical alcohol can be used to wipe the surface of an object and kill Covid-19, it can’t do anything about the virus that has already entered the body, not to mention that almost all white spirits can’t achieve such a high alcohol content of medical alcohol. Besides,Drinking alcohol itself may stimulate the human body, aggravate symptoms, and may affect the effect of taking medicine.Besides, drinking alcohol is inherently bad for health.
Can salt water gargle prevent Covid-19 infection?
Salt water does not have this function.
Team Zhong Nanshan refuted the rumor: gargling with salt water is beneficial to cleaning the mouth and throat, and is helpful for pharyngitis.But novel coronavirus invaded the respiratory tract, and there was no way to clean the respiratory tract by gargling.Secondly, at present, there is no research result suggesting that salt water can kill novel coronavirus.
Can taking medicine prevent COVID-19?
There is no such medicine.
At present, there is no drug that can definitely reduce the possibility of COVID-19 infection. Whether it is the so-called COVID-19 specific drug that is popular on the Internet or cold medicine, it is impossible to prevent Covid-19 infection by taking drugs in advance.Keep wearing a mask, wash your hands frequently, ventilate your home frequently and keep a social distance.Besides other protective measures, it is the right way to keep yourself healthy, exercise moderately and sleep well.
02
These operations are unnecessary!
Can the mask be cleaned and reused?
You can’t.
At present,Both medical surgical masks and N95 protective masks are disposable products, and their protective performance may decrease after cleaning or disinfection.Because the mask used for a period of time may be attached with viruses, it may also bring pollution when cleaning. Therefore, we need to change new masks regularly, and if the masks are dirty and damaged, we should change them at any time.
COVID-19 can cause hypoxia, so you should prepare an oxygen generator at home?
If the family doesn’t need oxygen, there is no need to buy an oxygen generator to cope with COVID-19.
Oxygen inhalation therapy should be carried out under the guidance of a doctor. Too high concentration or too long time will lead to oxygen poisoning, so you must not judge for yourself.
Covid-19 infected people also need to take oxygen according to their condition.Asymptomatic and mild cases do not need oxygen inhalation, and ordinary cases need oxygen inhalation as needed;Severe and critical cases need oxygen inhalation, but the oxygen inhalation of Covid-19 infected people is also an adjuvant therapy, which needs to be used on the basis of combined treatment. To this extent, it is useless to only inhale oxygen at home.
Instead of preparing an oxygen generator, it is better to prepare a finger oximeter.
Can you identify Covid-19 infection by listening to a cough?
Don’t take it seriously.
Positive novel coronavirus nucleic acid test is the gold standard for judging Covid-19 infection.Cough is just a symptom. Many diseases may cause cough, not necessarily caused by COVID-19. In addition, such small programs sometimes need to fill in personal information, which may cause sensitive information to be leaked, so everyone should be cautious.
Do you want to store some antigen test kits for regular testing to ensure that you are not infected?
It’s not necessary.
Antigen testing should be used to determine whether it is Covid-19 infection after typical symptoms such as headache and fever have appeared, and there is no need to detect antigens regularly. Test once if you have symptoms, and test 1-mdash during illness; Twice, and considering that even repeated infections are usually separated by several months,In fact, we only need to keep 2— Three antigen test kits will be fine,There is absolutely no need to buy dozens of people at a time.
Infected with Covid-19, can it be better to take more drugs?
Mistake.
This practice may be life-threatening. Each drug has strict usage and dosage, and correct medication can not only cure the disease, but also cause less side effects. Taking a variety of drugs without authorization can easily lead to repeated medication and overdose, which is harmful to human health. Although some drugs have different trade names, their chemical components are the same, and they still belong to the same drug. If they are used together at will, it is very easy to cause excessive intake of drugs and cause danger.
Therefore,If you have a doctor’s advice and prescription, you should take the medicine according to the doctor’s advice, and you should not add medicine at will.For mild patients treated at home, it is recommended to use drugs according to the guidelines of home treatment of the Health and Health Commission. Read the instructions carefully before taking the medicine, and don’t take several medicines at once.
03
These blame, masks don’t carry!
Wearing a mask can lead to lung nodules and turn into lung cancer?
Don’t worry.
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. Besides, in most cases,"Pulmonary nodules ≠ Lung cancer "Don’t be too anxious. Wearing masks correctly is still one of the effective ways to resist Covid-19.
Wearing a mask can lead to hypoxia?
Depending on the situation.
For healthy ordinary people, experiments have proved that even wearing a 7-layer medical surgical mask has little effect on blood oxygen saturation. butN95 or a mask with higher protective performance,It is more suitable for professionals in high-risk environment, or ordinary people who need to go to the hospital to wear it temporarily, because wearing the N95 mask for a long time may cause discomfort.
In addition, people who are prone to poor breathing, such as smokers, emphysema patients and obese people, wearing N95 masks may make things worse and even aggravate their breathing problems.
The mask contains graphene, which is harmful to human health?
Fake.
At present, the so-called "graphene masks" sold in the market are mostly gimmicks, such as a "biomass graphene" raw material, which has been verified to be processed from straw. It is worth noting that some mask materials use nano-scale activated carbon.Wearing an activated carbon mask for a long time does pose the risk of inhaling particles.For daily epidemic prevention, the public should choose protective masks that meet the national standard, and do not choose gimmicks.
The mask contains ethylene oxide, which will cause cancer when worn?
Don’t worry.
Ethylene oxide is a common and easy-to-use disinfectant, which can be used for low-temperature sterilization. Food packaging, baby diapers, sanitary napkins, masks, etc. can all be disinfected with ethylene oxide. Ethylene oxide itself is volatile,The mask is disinfected with ethylene oxide. After disinfection, it will stand and dissipate for a period of time according to the regulations, and it can only be sold on the market after the content reaches a safe range.So don’t worry about buying qualified masks.
04
These worries are unnecessary!
Have a fever is infected with Covid-19?
Not necessarily.
Fever is only a symptom, not a diagnosis of disease.You can’t judge what disease you have by your fever, so you can’t diagnose COVID-19 by the symptom of "fever". The diagnosis and treatment plan also says that the diagnosis should be made according to the comprehensive analysis of epidemiological history, clinical manifestations and laboratory tests. Positive novel coronavirus nucleic acid test is the primary criterion for diagnosis. "
Eating oranges, oranges and other fruits can lead to positive antigen test?
It’s unlikely.
If the operation is correct during antigen detection, the sampling site is nasal mucosa, even if you eat oranges, you will not come into contact with orange juice here, so it has no effect. butOrange juice can make the antigen test positive because it destroys the suitable pH environment.However, this in itself does not meet the sampling standards, and the results are meaningless, which does not mean that the antigen detection is inaccurate.
The strains prevalent in Beijing are more virulent than those in Guangzhou, which makes people feel worse?
That’s not true.
Whether it is uncomfortable or not is mainly personal feelings.In fact, the BF.7 mutant prevalent in Beijing and the BA.5.2 mutant prevalent in Guangzhou are both branches of Omicron, and their infectivity and pathogenicity will not change substantially. As for the different personal symptoms, this may be related to factors such as physical fitness, age, and whether there is a basic disease.
Sooner or later, everyone wants Yang, so it’s better to get infected as early as possible, as early as Erwin Engst?
Don’t try.
After being infected with Covid-19, you will gain immunity against this strain within a certain period of time, but that doesn’t mean you won’t be infected again. Compared with Delta and its previous variants, Omicron is more likely to cause reinfection. Besides,Repeated infections still have a certain risk of serious illness.It will be transmitted to high-risk groups such as the elderly at home and those with basic diseases. Therefore, we should still pay attention to personal protection and vaccinate in time.
COVID-19’s sequela is very serious?
Not really.
Tong Zhaohui, an expert in respiratory critical illness, said that the research on post-COVID-19 symptoms is aimed at the previous strains. At present, it should be said that there is no observation of post-COVID-19 symptoms in Omicron. But,More than 90% of Omicron is asymptomatic and mild, and its symptoms are mainly manifested in the upper respiratory tract.For example, low to moderate fever, cough, sore throat, 5 days, 7 days will be fine.
From the common sense, there should be no sequela, because it is in the upper respiratory tract and does not affect the organs and tissues in our body. At least there is no relevant literature at home and abroad to support this statement.
On April 17 th, Xiaomi technical officer Wei issued a document today, officially revealing the Xiaomi automobile factory.
