COVID-19 has become a "trumpet AIDS" again? It's not the same thing!
In fact, many COVID-19 drugs are used as anti-AIDS drugs. Some people's residual stuffy nose, cough, decreased sense of smell and taste do not belong to the category of sequelae, with the progress of the disease and the gradual relief of symptoms. It is not impossible to take proper replenishment after positive recovery, including the recovery of digestive tract. It is rumored that COVID-19 can hold breath for 40 seconds or more. COVID-19 can hold breath for more than 40 seconds. Holding breath for 30 seconds can test lung health. It shows that the focus of pneumonia has been obviously absorbed, simple holding breath can not reflect the true state of the lungs, and the breath holding time or lung function tests of many patients are still normal in clinic. Rumor coenzyme Q10 can prevent and cure myocarditis induced by COVID-19 and prevent viral myocarditis. A large amount of coenzyme Q10 is needed after infection with COVID-19. There is no evidence that coenzyme Q10 can prevent myocarditis induced by COVID-19 infection.
At present, this round of COVID-19 epidemic has come to an end in many parts of the country, and most of the cases are in a sporadic state. However, various "legends" about COVID-19 are still being updated. Recently, a saying began to spread on the Internet and moments, "COVID-19 is not a large flu, but a small AIDS." Some people even solemnly pointed out that "many COVID-19 drugs are actually used as anti-AIDS drugs." Is this really the case? The monthly "Science" gossip list focuses on refuting the recent COVID-19 rumors.
The monthly "Science" gossip list is guided by the Beijing Science and Technology Association, the Network Information Office of the Beijing Municipal CPC Committee, and the Capital Internet Association, and jointly released by the Beijing Science and Technology journalists' Association and the Beijing area website.
Rumor
After "Yangkang", you can swallow mustard and drink soy sauce to awaken taste.
If there is a loss of taste after COVID-19 's "Yangkang", he can "awaken" his sense of taste by swallowing mustard and drinking soy sauce.
Truth: if COVID-19 infected people lose their sense of taste and smell, they can improve themselves after two weeks to a month after the course of the disease. It is not advisable to try to restore the sense of taste with all kinds of irritating food. Eating all kinds of irritating food may also damage the local oral mucosa and even the mucous membrane of the digestive tract.
After the acute stage of novel coronavirus infection, the residual stuffy nose, cough and decreased sense of smell and taste in some people do not belong to the category of sequelae, but are only one of the symptoms of viral infection.
Decreased sense of smell and taste is a "transient" symptom after infection. With the progress of the disease and the gradual relief of symptoms, most people can return to normal on their own and do not have to worry too much.
Rumor
After "Yangkang", we should sit in "Xiao Yuezi".
After COVID-19 's "Yangkang", he should have a "little month", eat and drink openly, make up a lot, and rest and recuperate for 30 days.
Truth: it is not impossible to take appropriate supplements after positive recovery, but there is no need to "sit on the moon". Do not act in haste. After COVID-19 's "Yangkang", the recovery of many organs, including the digestive tract, will still take a certain period of time, and it may be more safe to follow the principle of "from less to more, step by step", or overeating may be counterproductive, and haste makes waste.
For those who can eat normally, Yangkang can follow the basic principles of the 2022 edition of the Dietary guidelines for Chinese residents: try to keep the food diversified, the table rich and colorful, and maintain good eating habits.
For example, regular and quantitative meals for three meals a day; ensure the intake of several important nutrients or foods, including but not limited to high-quality protein; make a good combination of meat and meat for three meals a day, so that there are vegetables and fruits for meals every day; keep adequate drinking water, drink a small amount, many times, and drink regularly, and maintain good habits.
Rumor
COVID-19 's recovery standard is to hold his breath for 40 seconds.
COVID-19 recovery standard is to be able to hold breath for more than 40 seconds, less than 40 seconds means there is something wrong with the lungs.
Truth: this rumor is likely to be a variation of the old rumor in early 2021 that holding your breath for 30 seconds can test lung health.
COVID-19 has clear criteria for recovery, as listed in the ninth edition of the diagnosis and treatment plan: first, the body temperature returns to normal for more than 3 days; second, the symptoms basically disappear or significantly improve; third, those with symptoms of pneumonia show that the focus of pneumonia has been obviously absorbed when they are re-examined by CT; fourth, the nucleic acid test is negative for two consecutive days, or the Ct value is ≥ 35, or three times the antigen is negative. If the above conditions are met, the cure standard can be reached.
Simply holding your breath does not reflect the true state of the lungs. Clinically, the suffocation time or lung function test of many patients is still normal, and some people with normal lung function are unable to hold their breath for various reasons. In the 10th edition of COVID-19 's diagnosis and treatment plan released on January 6, 2023, it was not mentioned that "holding your breath for more than 40 seconds is the standard for COVID-19 's recovery."
Rumor
Coenzyme Q10 can prevent and cure myocarditis induced by COVID-19.
Coenzyme Q10 can prevent viral myocarditis, and a large number of coenzyme Q10 should be supplemented after infection with COVID-19.
Truth: there is no evidence that coenzyme Q10 can prevent myocarditis induced by COVID-19 infection, and coenzyme Q10 only plays an auxiliary role in the treatment of heart diseases. Some businesses released the so-called "coenzyme Q10 can prevent COVID-19 positive post-myocarditis" publicity, just rub novel coronavirus's hot spot.
Coenzyme Q10 should be taken as a drug under the guidance of a doctor or pharmacist, and it is not recommended to take it in large quantities for a long time as a health product. Coenzyme Q10 in the human body is mainly synthesized by itself, with only a small amount of supplement from food. When the human body is not short of coenzyme Q10, a large number of supplements do not bring additional benefits. Some people may benefit from appropriate supplementation of coenzyme Q10, but they need to fully evaluate their own needs and supplementary goals.
Rumor
COVID-19 is a "trumpet AIDS".
There is a saying on the Internet recently: "COVID-19 is not a large flu, but a small AIDS."
Truth: COVID-19 is not a "trumpet AIDS". Both of them are caused by different kinds of viruses, and their ways of transmission, pathogenesis and treatment are also different.
First of all, the pathogenesis is different. HIV is not a coronavirus, the full name of AIDS is acquired immunodeficiency syndrome. Compared with other diseases, the biggest difference of HIV is that it attacks the human immune system, takes the most important CD4T lymphocytes in the human immune system as the main target, destroys the cells in large quantities, and makes the human body appear immune function deficiency in varying degrees. Untreated infected people are prone to a variety of serious infections and malignant tumors in the late stage of the disease. And novel coronavirus's full name is "novel coronavirus". When the Omicron virus strain invades the human body, the first person to be invaded is the respiratory system, that is, the upper respiratory tract, which usually shows symptoms such as dry cough, expectoration and sore throat, but it does not destroy the body's immune system like the AIDS virus. causing immune deficiency. After novel coronavirus is cured, it will not cause other diseases to be infected more easily, and novel coronavirus can be cured.
Secondly, the ways of transmission are different. There are three ways of AIDS infection, namely, sexual transmission, mother-to-child transmission and blood transmission. Novel coronavirus is mainly transmitted through the respiratory tract, but also through the air and objects as a medium.
Third, the treatment plan is different. AIDS is different from other diseases, the most important thing is that it cannot be cured at present. At present, the main purpose of drug treatment is to control HIV and avoid complications. Novel coronavirus can be completely cured. For people with normal immune function and no basic diseases, they can recover after taking some drugs to relieve symptoms (antipyretic medicine, cold medicine, cough medicine) or COVID-19 medicine.
Although novel coronavirus is different from HIV, they all use RNA as genetic material and belong to the RNA virus category, so some of the drug targets for the treatment of AIDS are the same as those for COVID-19, which can be used to treat COVID-19 and other similar viral infections.
It can be seen that it is inappropriate to call COVID-19 "large flu" or "small AIDS". COVID-19 is COVID-19, calling it "large flu" may underestimate its influence, while calling it "small AIDS" may cause unnecessary fear. We need to know COVID-19 more rationally and objectively, rather than putting on a cloak that is easy to be misunderstood.
Rumor
Setting off fireworks can disinfect
The composition of firecrackers contains sulfur, which is ejected when it is fired, which is equivalent to sterilizing the air.
Truth: trying to disinfect by setting off fireworks and firecrackers will only do more harm than "no disinfection", and the loss outweighs the gain.
There are two main ingredients of firecrackers: one is black gunpowder (charcoal, sulfur and nitrate), and the other is silver powder gunpowder, that is, aluminum powder is used instead of charcoal in black gunpowder. The fireworks will also add metal salts that can produce a flame reaction. Fireworks and firecrackers will produce a large number of sulfur dioxide, nitrogen oxides and / or metal oxides, in which sulfur dioxide will react with water vapor to form acidic sulfite, which can be further oxidized to sulfuric acid; nitrogen oxides can also react with water vapor to form nitrous acid or nitric acid, these acidic compounds are highly corrosive. However, for the antivirus effect of sulfur dioxide in aerosols, there is still a lack of corresponding research in the scientific community-under what conditions and how high concentration can achieve the effective effect of killing the virus is not clear.
But what is certain is that the human body will be significantly harmed in an environment with high concentrations of sulfur dioxide. Sulfur dioxide and the sulfite and sulfuric acid produced by it are highly corrosive, especially to mucosal areas such as eyes and respiratory tract, and high concentrations of sulfur dioxide can even cause pulmonary edema.
Rumor
The banana was found to have excessive formaldehyde.
Cut the banana into pieces and test it with a card labeled "colorimetric level of air formaldehyde rapid measuring agent". The changed color shows that "banana formaldehyde exceeds the standard".
Truth: formaldehyde detection kit is mainly composed of four parts: chromogenic agent, absorbent, absorption box and colorimetric card. This kind of product mainly uses "phenolic reagent coloration method" to measure the concentration of formaldehyde in the air, that is, making use of the characteristic that formaldehyde is soluble in water, using absorbent (phenolic reagent) to absorb formaldehyde in the air, after adding chromogenic agent, according to the color after chemical reaction, refer to the colorimetric card to judge the concentration of formaldehyde in the space. However, this kind of products are specially used to detect the concentration of formaldehyde in indoor, furniture and other specific spaces, and it is used to detect the "aldehyde content" in fruits and vegetables, which is the wrong measurement tools and methods, and the conclusion is obviously unscientific.
It is illegal to add formaldehyde to food in any way. However, formaldehyde exists widely as an intermediate of growth and metabolism in organisms, and formaldehyde is produced in edible fungi, vegetables, fruits, meat products, dairy products, aquatic products and even the human body. Some agricultural products such as fruits and vegetables will naturally metabolize to produce trace formaldehyde in the production process, but this is not caused by artificial addition or environmental pollution, and has no harm to the human body.
