What are the top ten rumors of friends circle in 2020?

1, food shortage, grab rice, oil and salt quickly.

Rumor has it: "Affected by the epidemic, there is a shortage of food in China, so we must quickly hoard rice and grab oil."

Truth: In this regard, the Ministry of Agriculture and Rural Affairs, the State Grain and Material Reserve Bureau and other departments responded: "China's grain production and inventory are sufficient, the market commodity prices are stable, and the supply of rice and flour is sufficient, so there is no need to snap up and hoard." So you can rest assured.

2. Garlic water and white wine can kill novel coronavirus.

During the epidemic, there was a "folk prescription" circulating on the Internet: "Eating garlic and drinking high-alcohol can destroy COVID-19, and the effect is better than other epidemic prevention supplies."

Truth: At present, there is no specific food that can help people resist COVID-19. Therefore, neither garlic nor white wine can kill COVID-19. When we often say alcohol disinfection, we don't mean drinking alcoholic beverages. The wine in the stomach enters the digestive system, while COVID-19 infects the respiratory system.

3. Academician Zhong Nanshan went to a certain place to assist in epidemic prevention and control.

With the progress of the epidemic, news such as "Academician Zhong Nanshan landed in Chengdu", "Zhong Nanshan has arrived in Urumqi, Xinjiang to fight the epidemic" and "Zhong Nanshan went to Europe to guide other countries to fight the epidemic" appeared on the Internet one after another.

Truth: The rumored trip of Academician Zhong Nanshan was made out of nothing. Whenever a new confirmed case appears in COVID-19, similar false rumors will be updated simultaneously.

4. The national timetable for removing masks was released.

Truth: After verification, the relevant departments and the media did not say that they could take off their masks.

Experts believe that other respiratory infectious diseases are about to enter the epidemic season, and the increase in personnel mobility and gathering activities during the Spring Festival will further increase the risk of epidemic spread. Wearing a mask is still an important means of self-protection.

Mosquitoes and flies can spread COVID-19 virus.

It is said that mosquitoes and flies can spread COVID-19 virus by biting humans or other animals.

Truth: Wang Liping, a researcher at China CDC, said that according to the current research, mosquitoes and flies do not have the biological basis to spread COVID-19 virus. At present, no one has been reported to be infected with COVID-19 virus due to mosquitoes, flies and other vectors. COVID-19 is mainly transmitted by droplets, or after contact with objects contaminated by infected people, it is transmitted and infected through eyes, mouth or nasal mucosa.

6. The disaster in the year of Gengzi in 2020

Gengzi's online biography is full of disasters, and remarks such as "Earth's gravitational field/magnetic field disorder" and "geological/climate catastrophe" frequently brush the sense of existence on major platforms.

Truth: The so-called "recent disorder of the earth's gravitational field and magnetic field" lacks scientific basis. According to the long-term observation of the total solar radiation, solar activity and the earth's magnetic field by Fengyun satellite in orbit in China, no abnormalities have been found at present. Yang Jun, director of the National Satellite Meteorological Center, also said that there is no evidence that the problems mentioned in the rumor are related to the heavy precipitation in the south and this year's disaster.

7, sesame oil dripping in the nostrils can block all influenza and plague infections.

"Dip a cotton swab into a little ground sesame oil before going out every day, drop it into two nostrils and gently pinch it a few times." This practice of online communication can block the spread of all influenza and plague and is widely forwarded.

Truth: Dr. Yun inadvertently pointed out that both influenza and plague are caused by virus infection. Applying sesame oil to the nostrils can neither prevent the virus from entering the human body, nor affect the replication and proliferation of the virus, so it has no defensive effect on influenza and plague.

8, runny nose and expectoration, can't be novel coronavirus.

This summer, many WeChat groups spread the news: "COVID-19 has a dry cough and no runny nose, so it's not COVID-19 that has symptoms of expectoration and runny nose".

Truth: According to the "Diagnosis and Treatment Plan for Pneumonia in novel coronavirus (Trial Fifth Edition)" issued by National Health Commission, the clinical manifestations of pneumonia in novel coronavirus are fever, fatigue and dry cough, and a few patients are accompanied by symptoms such as nasal congestion, runny nose and diarrhea. Therefore, it is not accurate to judge whether COVID-19 is infected according to his runny nose and expectoration.

9. A powerful hair dryer can sterilize masks, faces and hands for 30 seconds.

The saying that "the mask, face and hands can be disinfected in 30 seconds with a hair dryer" once dominated the circle of friends, and an upgraded version said that "this method can make the mask be used repeatedly".

Truth: COVID-19 is really sensitive to high temperature. In an environment above 56℃, Zhong Zhen can be extinct in 30 minutes. However, it is said that the method of using hair dryer can not meet this condition, not only can not kill the virus, but also may damage the skin of face and hands.

10, saute spicy chicken, barbecue and cold salad were infected with HIV.

An "urgent notice" on the Internet said: "Recently, under the command of terrorist forces, people poured into cities all over the country and dripped the blood of AIDS-infected people into food."

Truth: Guo Caiping, chief physician of Beijing You 'an Hospital Infection Center, explained that AIDS is not transmitted through food. Once HIV is out of the body fluid environment, its viability and pathogenicity will decline. With the death of blood cells and lymphocytes, HIV without living blood will lose its ability to proliferate and then die.
