NO.1 Bats carry so many viruses, should they be eliminated directly?
Since the outbreak of the new crown pneumonia outbreak was related to bats, this flying mammal has been searched for several times. As people know more and more relevant information, especially the characteristics of bats as “virus reservoirs”, the public has changed from fear to aversion to them. Some people even suggested that since their existence is such a threat, they should Kill this animal directly.

Interpretation of the truth: Bats need protection, not hunting. First of all, bats have a rich and diverse diet and play an important role in maintaining the stability of natural ecosystems and biodiversity. Bats are also seed dispersers and pollinators of many plants. Secondly, bats have great scientific research value. Bats have many unique behaviors and physiological characteristics, such as superb echolocation capabilities and flying skills, strong immune function, and low probability of cancer. The study of these special physiological characteristics and behaviors of bats will provide many useful inspirations for human survival and biomedical research. The main way to avoid zoonotic diseases is to fast wild animals, strictly prohibit hunting wild animals, and reduce contact with wild animals. In addition, it is necessary to protect the living environment of wild animals, reduce interference with wild animals, and achieve harmonious coexistence between man and nature.

NO.2 The higher the protection level of masks, the more worth buying
The higher the protection level of masks, the more worth buying. Choose a mask to block the virus, just look at the level of protection.

Interpretation of the truth: blocking viruses can’t just look at the level of protection. According to the national standard “Technical Specifications for Daily Protective Masks” (GB/T 32610-2016), the protection level specifically refers to the protection of air pollution, and the protection of air pollutants is very different from the protection of pathogens such as viruses. Even if the KN95 and N95 masks seem to have a high level of protection, there is a difference between medical and non-medical masks. To meet medical requirements, it should meet the national standard “Technical Requirements for Medical Protective Masks” (GB 19083-2010). Even if it can achieve 95% filterability, the medical standard has one more “surface moisture resistance” than the daily protection standard, that is, it can prevent body fluids from splashing. Most of the KN95 masks commonly purchased by the public conform to the national standard “Respiratory Protective Equipment-Self-priming Filtered Anti-Particulate Respirator” (GB 2626-2006), which is sufficient for the daily protection of the general population. However, as medical personnel, they must use Medical protective mask according to the national standard GB 19083-2010.

NO.3 Garlic can prevent new coronary pneumonia
It is said that after 15 minutes of oxidation of garlic slices, put it in your mouth and bite it, hold it for a while, swallow your saliva, and spit out the garlic cloves, which can effectively kill the new coronavirus. Of the 1.46 million people in Lanling County, Shandong Province, none of the Lanling people who worked in Wuhan were infected because the locals love to eat garlic.

Interpretation of the truth: This statement is not scientific. Garlic has a certain health promotion effect, but it is not equivalent to medicine. The effective ingredients in garlic are sulfur-containing compounds such as allicin. In vitro studies have found that allicin has the effects of sterilization, bacteriostasis, anti-cancer, and anti-aging, but the content of allicin in garlic is limited. Even if it is oxidized in the air for 15 minutes, it will increase, and it still cannot be compared with drugs. Whether it is taken with hot water or in the mouth, it cannot improve its effect, not to mention the “swallow saliva and spit out garlic cloves” method mentioned in the rumors, and there is no existing literature about garlic that can inhibit the new crown. Virus research.

NO.4 Squeezing edible oil is better than leaching edible oil
Some people only think of pressed oil because of the rumor that “gasoline is needed for the leaching process”, and many pressed oils on the market have various health banners, and some even directly emphasize that they produce purely hand-pressed oil.

Interpretation of the truth: Whether it is squeezed oil or leached oil, as long as it is edible oil produced by a regular manufacturer and meets the quality standards, you can eat it with confidence. The leaching process is indeed related to No. 6 light gasoline, which is the processing aid “n-hexane” used in the food industry. However, according to the national standard “National Food Safety Standard: Standard for the Use of Food Additives” (GB 2760-2014), n-hexane is not allowed to be detected in the final food test, so consumers do not have to worry about leaving behind in the edible oil on the market. Gasoline is harmful to health. As for the purely hand-pressed oil produced in-house, there is likely to be aflatoxin contamination during its production process, and long-term consumption may be harmful to health, so it is not recommended to consume it.

NO.5 Electric vehicles and hybrid vehicles do not require hot cars
As the cold winter is approaching, many drivers face a problem when they start their cars in the morning-a hot car. However, it is said that electric vehicles and hybrid vehicles do not require hot cars, because new energy vehicles do not have the engines and gearboxes of traditional fuel vehicles.

Interpretation of the truth: When the ambient temperature is low in winter, electric vehicles and hybrid vehicles need more “hot cars”. Although new energy vehicles do not have the engines and gearboxes of traditional fuel vehicles, they have power batteries, and ambient temperature is one of the leading factors affecting the performance of power batteries. At a lower ambient temperature, side reactions increase during the charging and discharging process of the power battery, and its performance will be greatly reduced. But at present, most new energy vehicles are equipped with power battery preheating systems and thermal management systems, so there is no need for the driver to actively “warm the car”, but in low temperature conditions, you should drive as smoothly as possible for a period of time after starting. To avoid slamming the accelerator.

NO.6 The use of disposable chopsticks can be infected with the new coronavirus
Since the beginning of the winter, the national temperature has dropped sharply, and the new crown pneumonia epidemic has shown an upward trend, with clusters of epidemic outbreaks in many places. All kinds of gossips were flying all over the sky. Recently, there were rumors that “Shijiazhuang, Hebei Province is one of the main producing areas of disposable chopsticks. Rural areas near Shijiazhuang are the epicenter of the epidemic. Disposable chopsticks from these areas may carry the virus. It is very likely to be infected with the new coronavirus”.

Interpretation of the truth: Disposable chopsticks are unlikely to spread the new crown virus, so don’t worry too much. First of all, the disposable chopsticks we use in our daily lives may not come from risky areas, and the products in question will not be sold on the market. Up to now, there is no report about the contamination of disposable chopsticks. Secondly, the environment and objects may indeed spread the virus. Researcher Wu Zunyou, the chief epidemiologist of the Chinese Center for Disease Control and Prevention, said that under low temperature conditions, such as -10 to -1°C, the new coronavirus can survive for several weeks to several months , The survival time may be longer in low temperature and humid conditions, while the survival time of the new coronavirus on the surface of an object at room temperature generally does not exceed 24 hours. Third, except for small workshops that do not have production qualifications, formal manufacturers mainly use mechanized production, and they may have direct contact with relevant personnel only during packaging and transportation, and the overall risk is not high. Pay more attention to official notifications and do a good job in the prevention and control of the epidemic.
