In the recent domestic epidemic,
asymptomatic infections has increased significantly compared to before
Everyone is very concerned about
Why does asymptomatic infections suddenly increase? What is the difference between
and confirmed cases? How long does
take to turn negative? Does
need treatment?
…
Let’s read down together!
What is an asymptomatic infected person?
Simply put,
means that the patient carries the new coronavirus
but does not occur, and has no obvious symptoms
I don’t know that I have new coronavirus
Isn’t asymptomatic?
What is the difference between the two?
nucleic acid test result is positive
There are clinical symptoms, such as fever, cough, etc.
There are imaging changes in the lungs
No clinical symptoms, there are imaging changes in the lungs
nucleic acid test The result is positive
No clinical symptoms
There are no clinical symptoms
Lung imaging has not changed
Asymptomatic infected people conduct blood routine , CT imaging examinations and antibody tests during centralized isolation and medical observation. If relevant symptoms or signs appear in subsequent cases, they will be revised to a confirmed case within 24 hours after meeting the diagnostic criteria for confirmed cases.
The following situations
Asymptomatic infected persons can be diagnosed as confirmed cases
∨
01. Asymptomatic infected persons have tested positive for nucleic acid and have begun to show symptoms;
02. After observing for a period of time, symptoms such as cough, fever, and fatigue appear;
03. Asymptomatic infected persons have no clinical symptoms, but there are lesions in the lung CT examination.
Will asymptomatic infected persons infect others?
Asymptomatic means that the infected person has no symptoms
does not have contagious
and the transmission route of asymptomatic infected person
is the same as confirmed cases
specifically includes:
direct transmission, aerosol transmission and contact transmission
✓ direct transmission
The droplets that the exhaled gas is sneezing, coughing, and speaking, and the exhaled gas is directly inhaled from close range to cause infection;
✓ Aerosol spread
droplets are mixed in the air to form aerosol , which causes infection after inhalation;
✓ Contact spread
droplets are deposited on the surface of the item, and after contacting the contaminated hands, they contact the mucosa such as the mouth, nose, eyes, etc., resulting in infection.
So
For asymptomatic infected people,
, the same needs to be carried out for close contacts and secondary close contacts,
, screening for high-risk groups and corresponding place control measures.
How to find out the asymptomatic infected people?
is usually tracked through
. Close contacts of confirmed patients . 3. Nucleic acid screening for key personnel found that
. There are usually 2 situations in
. Patients are in the incubation period, especially in the middle and late stages of the incubation period, and nucleic acid positive was found;
② The patient has mild symptoms and has healed himself. During the recovery period, he was found to have antibodies or nucleic acid positive.
Why are there many asymptomatic infections in
during this epidemic?
is related to Omickron mutant strain
The new coronavirus is constantly mutating, with strong transmission, but its pathogenicity is declining, so the symptoms caused by the Omickron mutant strain are relatively mild.
is related to large-scale immunization
With the immunization of large-scale populations, vaccination plays a very important role in protecting the majority of susceptible populations. The severe and mortality rates after infection are decreasing, and the proportion of mild or asymptomatic symptoms is increasing.
is related to early detection and control
disease control and early rapid screening of health systems, so that some early infections were discovered before they showed clinical symptoms.
is related to the immunity of infected subjects
is related to the immunity of infected subjects. Asymptomatic conditions are more likely to occur among young people.
What proportion of asymptomatic infections will become a confirmed case?
At present, it is not possible to know exactly what proportion of asymptomatic infections will become confirmed, but it is certain that the proportion of asymptomatic infections varies depending on the mutant strain.
At present, it seems that the probability of the delta mutant invading the lower respiratory tract is high, the probability of the Omickron mutant invading the upper respiratory tract is high, and the symptoms of infection with the upper respiratory tract of are even milder. Compared with the delta variant, the proportion of asymptomatic infections in the Omickron variant is relatively high.
Do asymptomatic infections need treatment?
At present, asymptomatic infections do not need special treatment.
Future antiviral small molecule drugs such as those on the market may be used for asymptomatic infections. What the infected person needs to do is to take a full rest and recover as soon as possible.
How long will it take for asymptomatic infected people to turn negative?
Asymptomatic infections of Omickron According to current clinical treatment experience, the time for turning negative is not essentially different from that of mild or ordinary patients, usually about two weeks. However, it is not ruled out that some infected people will turn negative in 6 to 7 days.
Asymptomatic infections increase in
How to protect yourself?
01
Wear a mask
Wear a mask when going out or in public places, parents should also let their children wear masks.
02
Hand washing
Hand washing Three elements: first soap, second washing 20 seconds, third running water washing.
When transferring, if you take public transportation and go into the office or go home, you have to wash your hands, you have to wash your hands after going to the toilet, you have to wash your hands after taking the express delivery, and you have to wash your hands when you touch things in public places, this should become a conscious habit in our daily life.
03
Home protection
Pay attention to maintaining good personal and environmental sanitation, open windows frequently in the room, and ventilate frequently, and family members do not share towels. Keep furniture, tableware clean, etc.
Balanced nutrition, exercise appropriately, and rest sufficiently, avoid excessive fatigue, go out less, and do not gather.
