Refute rumors
At the end of the year, the rumors of "noisy" for a year have not ceased
With the recent wave of cold waves, these "hot" rumors that emerged in December should also be cold
Will you get hemorrhagic fever if you eat strawberries?
The truth: The main route of transmission of the disease is from rats to humans
Since the beginning of winter this year, major hospitals in Xi'an City, Shaanxi Province have received many cases of hemorrhagic fever
"Eating strawberries and suffering from hemorrhagic fever are not directly related
China is an area with a high incidence of haemorrhagic fever, and rodents are the main source of infection
"In fact, it's not just strawberries.
Finally, Wang Yimin reminded that hemorrhagic fever is a preventable and curable disease.
"White light" appeared in many places in Henan, UFO visiting the earth?
The truth: Space rocks broke into the Earth’s atmosphere
Not long ago, "white light" appeared at night in many parts of Henan Province, lighting up the entire night sky
"I have seen the recorded images and think this is a bolide event
According to the official website of the National Aeronautics and Space Administration (NASA), on the night of the "white light", an asteroid exploded over Henan Province, China.
"There are many asteroids between Mars and Jupiter.
Omi Keron carries the cold virus gene?
Truth: Two viruses cannot fuse
On December 8, the Director-General of the World Health Organization Tedros Adhanom Ghebreyesus said at a press conference in Geneva that the latest epidemic data from South Africa showed that the risk of infection with the mutant new crown virus Omi Keron has increased
"Omi Keron mutant strain is a new mutant strain of the new coronavirus, similar to the Alpha and Delta that appeared before, and it was caused by the mutation of the new coronavirus after the large number of people spread
Chen Chunqi pointed out that the Omi Keron mutant strain mainly mutates in the coat protein of the virus, and the coat protein of the virus is where the virus infects human cells
The more layers of mask meltblown cloth, the better the protective effect?
The truth: choose the right mask, one layer can achieve the protective effect
Delta's remaining prestige remained undiminished, and Omi Keron came again fiercely
Is this really the case?
"Choose the correct meltblown mask, one layer can achieve good protective effect
Melt blown cloth uses polypropylene as the main raw material and is composed of ultra-fine fibers
.
The meltblown cloth fiber used in medical protective masks has a finer diameter, which can reach 1 to 4 microns, and the meltblown cloth holes formed are also very thin, making it impossible for the new coronavirus to pass
.
"Some masks, such as medical surgical masks, anti-smog masks, etc.
, even if they contain meltblown cloth inside, they have limited protection against the new crown virus due to their different production processes; while pure cotton and gauze masks, no matter how many layers there are , Will not increase the protective effect against the new crown virus
.
” Qian Xiaoming reminded that when consumers buy or wear masks, they should not focus on the thickness or number of layers of the mask, but should pay attention to the protection category of the mask.
.
If you want to resist the new coronavirus, you should buy medical protective masks or N95 masks
.
Wearing multiple inappropriate masks will not only not prevent the virus, but may add illness to yourself
.
The "Guidelines for Public Scientific Wearing Masks" issued by the State Council's joint prevention and control mechanism for the new coronavirus pneumonia epidemic clearly pointed out that wearing multiple masks cannot effectively increase the protective effect, but will increase respiratory resistance and may damage the tightness of the masks
.
Finally, Qian Xiaoming reminded that in order to improve the protective effectiveness of masks, in addition to paying attention to the quality of protection of masks, it is also very important to wear them properly
.
The correct way to wear the mask should be to cover the mouth, nose and chin, and the nose clip should be compacted; if the mask is dirty, deformed, damaged, smelly, or wet, it needs to be replaced in time; on cross-regional public transportation, or on public transportation.
Do not reuse masks that have been used in hospitals and other environments; do not wear masks inside or outside
