As the number of people with "Yangkang" increases
netizens have new questions:
If there are no symptoms, is it not contagious?
I heard that it takes 15 days to produce antibodies.
Can you rest assured in the future?
In this regard
The Department of Infectious Diseases of Beijing Youan Hospital
Chief physician Li Tong once
provided an interpretation of netizens’ concerns
How to judge if you are really "yin"
According to the ninth edition of the diagnosis and treatment plan
The first thing is that the symptoms need to get better
For example, the body temperature has been normal for more than three days
Respiratory symptoms
have disappeared or are significantly relieved
If there is pneumonia
Look at CT and the lung lesions
have also begun. The absorption has improved
In addition, the nucleic acid test was negative twice
The two times must be separated by more than 24 hours
or nucleic acid CT value is greater than or equal to 35
, so it meets the conditions for turning negative
Li Tong once said
If the above conditions are met
The contagiousness is already very low
Asymptomatic, may still be contagious
Some netizens said that
after being infected with the new coronavirus
had no symptoms for five days
Is it not contagious?
Li Dong once suggested
It is best to quarantine for seven days
The vast majority of people turn negative after seven days
May still be contagious on the fifth day
At the same time, many netizens said
Although symptoms have turned negative
For example, if you have a cough
Li Dong once said
If you still have cough symptoms after turning negative
you must wear it after returning to work. Masks
Some special occupations
For example, staff in nursing homes and intensive care units
Or when preparing to visit the elderly, infants and young children
It is safer to be quarantined for ten days
He introduced
Coughing is a process of recovery
It will be replaced naturally The dead immune cells
The cells destroyed by the virus are excreted from the body
play a role in cleaning the "battlefield" and repairing the airway
How long or how short
But almost all can be completely cured within fourteen days
Within two weeks, it is less likely to be infected
Regarding the opinions spread on the Internet
"Antibodies can only be produced about two weeks after a positive test"
"A secondary infection is most likely about a week after a positive test "
Li Tong once said
The above statement is inaccurate
When a virus enters the human body
Immune system has already started working
The subsequent protective antibodies
will reach a peak in two or three weeks
Within these two weeks
the virus will enter again After entering the body
it will be cleared quickly
but it is relatively difficult to be infected.
Therefore, after the initial infection
people are concerned about the The virus has immunity
You can go and take care of other positive family members
ht with confidenceml0 Some netizens pointed out that
I still feel chest tightness, shortness of breath and weakness after "Yangkang"
Li Tong once said
These symptoms usually last two weeks. It can be relieved within two weeks. Can basically return to the state before getting sick
At the same time, remind
not to just recover
Engage in very heavy work immediately
Or start strenuous exercise or fitness immediately
Or do it step by step
Once you find problems such as fatigue and sweating
, rest quickly
Don't let it go, the virus is still mutating
For opinions spread on the Internet
"After being infected with the new coronavirus once
it is equivalent to being vaccinated with the new coronavirus vaccine "
Li Tong once said
infection cannot be used instead of vaccine
He introduced that after being infected with a strain of virus,
will produce high levels of protective antibodies against this strain.
It may last for more than half a year
The currently popular strains in my country, BA.5.2 and BF.7
, belong to the same branch of viruses
and infect one of them
has cross-protective effects with similar strains
will not infect
in the short term, but he also pointed out that
overall
The longer we are infected
the lower the antibody levels in the body
the greater the risk of infection
at the same time
If the virus continues to mutate
or become some distantly related strains
The risk of infection will also increase
In addition,
there are other respiratory infectious diseases in winter and spring
such as influenza and adenovirus , respiratory syncytial virus etc.
usually take more protection
get a booster shot after recovery
Li Tong once suggested
to continue to maintain good hygiene habits
wear a mask and wash hands frequently
open more windows for ventilation
Maintain social distance
Pay attention to cough etiquette, etc.
After recovery,
generally can obtain protection that lasts for 3 to 6 months.
Therefore,
Young people can get a booster shot after 6 months
Elderly people have shorter protection
You can get a booster shot after 3 months
Face the epidemic
Don’t be too nervous
Don’t be too relaxed
Branch Only by learning protection
can you protect yourself and the safety of those around you
Warm reminder:
While staying at home
Household electricity and gas consumption increased
Frequent use of disinfection products
Increased fire risk
These knowledge should be kept in mind
