Scientists reveal why Omicron is rampant: It's linked to asymptomatic!
Fauci: Omicron will eventually infect everyone
It is an indisputable fact that Omicron is surprisingly contagious
Just now, Fauci, an American infectious disease expert, also made a "pessimistic" comment:
"Omicron will eventually infect almost everyone"
If it was a month ago, you might have thought it was alarmist or scary
Why is Omicron so contagious?
A report published by Reuters today revealed one reason for the widespread spread of the Omicron variant: a very high rate of asymptomatic carriers
The findings come from two clinical trials conducted in South Africa, the birthplace of Omicron
One of the clinical trials was conducted last month when confirmed cases in South Africa surged, and the other resampled subjects around the same time
Both studies found that the number of people diagnosed with asymptomatic was much higher than other previous variants
The asymptomatic carrier rate during the Omicron outbreak was 16%, higher than the 2.
"The higher proportion of asymptomatic infections may be the main reason for the rapid and widespread spread of this variant," the researchers wrote
In layman's terms, in previous waves of outbreaks, infection was easy to identify and quarantine measures were taken due to the rapid onset of symptoms in confirmed patients; but with Omicron, those symptoms may have been coughing and dizziness for two days before spreading it Going out, groups of people who were asymptomatic and didn't know they had the virus went to supermarkets and restaurants, causing many people to be unaware of the infection in the middle
"Many people are infected but have no symptoms, so they continue to live their normal lives and spread the virus to others quickly
Even many times, people are unknowingly infected with Omicron without realizing that they have been infected for a long time
This is one of Omicron's unpredictable secrets, which spreads without a trace
On the other hand, another study today found that the coronavirus can linger in showers (bathrooms, steam rooms, swimming pools) and remain contagious for at least 20 minutes after an infected person leaves
Researchers at the University of Bristol in the UK have found that the SARS-CoV-2 virus reproduces more easily in moist environments
They found that when virus particles leave the moist environment of the lungs and enter the air, they dry out quickly
For example, in an office environment with only 40% humidity, the virus will lose half of its infectivity within 10 seconds;
However, if the surrounding air is also humid, such as a steam room, a shower room with a humidity of up to 90%, half of the virus particles are still infectious after 5 minutes, and 10% of the virus particles are still infectious after 20 minutes
If the study is true, swimming friends may be in trouble
.
Indoor pools and showers are extremely humid environments
.
Once someone is poisoned, it is extremely contagious
.
Therefore, keeping your distance and wearing a mask are the most effective ways to prevent infection
.
Although ventilation has a certain effect, the effect may not be large
.
Professor Jonathan Reed, lead author of the study, said: "I think the greatest risk of exposure to radiation is when you're near someone.

"
In addition, the study found that air temperature had no effect on the infectivity of the virus, contradicting the widely held belief that the virus spreads less in high temperatures
.
A bigger effect is humidity
