before, many places also predicted that the epidemic summit would arrive at the end of this month, but the peak would occur in mid-late January, around the Spring Festival.

that is to say, the most critical moment of our big exam is next month.

there are too many details we need to know about O'Micron 's infection, prevention and response.

recently, I have studied hard and summed up some of the issues that everyone is most concerned about right now.

I hope everyone will take a look at it. Whether it's yin or yang, it will be useful to you.

01

Food and supplies brought home from outside

infect you with novel coronavirus?

it's possible.

novel coronavirus can survive on the surface of vegetables, meat and commodities.

so, if the vegetable seller is infected, get the virus on the vegetable.

if you buy his food and take it home, you are bringing the virus into the house.

however, just because the virus enters the home does not mean that you and your family will be infected.

put on a mask when you wash vegetables, or don't touch your face, it won't get into your body.

then heat the food and cook it, and even if there is a virus on it, it will be wiped out.

here is a knowledge point that we must know:

viruses are different from bacteria.

bacteria can reproduce on "dead things". For example, if there are bacteria on a piece of meat, it can reproduce a large area.

but the virus can only reproduce on "living creatures". It can reproduce violently in our bodies.

but if it is an inanimate piece of meat, it can only stick to it and cannot reproduce.

so for example, if you buy a piece of meat and go home, how many viruses are there at that time? that's it at best.

and at room temperature, the survival time of the virus in food or household items is also very limited.

02

the two bars of antigen are yang?

No.

it has been proved that antigens often appear false negative.

many of my friends have a fever for two days after infection, and the antigen is also negative.

when the fever goes down, there are two bars.

so don't trust antigens too much in the early stages of the disease.

if you feel the symptoms are obvious, even if the antigen is negative, you should keep your distance from your family.

test again every two days.

these two pictures are widely circulated on the Internet. I think you can refer to them:

03

Why not recommend going to the hospital?

first, 90% of COVID-19 infections are asymptomatic and mild infections.

even if you go to the hospital, the doctor usually asks you to go home and take antipyretic medicine.

second, there must be some people in the hospital who go to see a doctor because of the flu.

it would have been hard enough for you to get infected with COVID-19. If you catch the flu there, the loss will really outweigh the gain.

third, most hospitals are full now.

if it is not serious, we will leave our limited resources to the critically ill.

04

Why do you have a fever above 38.5 ℃,

does the doctor suggest taking medicine?

when the virus invades our bodies, the body summons immune cells to destroy the virus.

immune cells rush from other parts of the body to the place where the virus invades.

when their body temperature is normal, their speed is limited and they need to run for a period of time.

but if you start to have a fever, the speed and vitality of immune cells will increase, not only quickly to the site of infection, but also more effective.

and when your body temperature reaches 38.5 ℃, it also activates a powerful immune cell and puts it into battle.

of course, if the temperature is too high or very uncomfortable, don't hold on.

05

Why are you sore all over?

that's because our bodies secrete a certain amount of interferon after the virus invades.

this kind of interferon can inhibit the replication of the virus, but it can also cause inflammation, and we will feel pain all over.

everyone's physical condition is different, and their tolerance to pain is also different, so everyone's feelings are different.

some people have back pain, some people have low back pain, and some people have joint pain.

it is said that where you are weak on weekdays, the pain may be severe.

is probably the meaning of "hemp rope is specially picked and broken, but misfortune is found to be unlucky".

06

under what circumstances must I go to the hospital?

although we say that more than 90% of people do not need to go to the hospital, some very dangerous situations do occur.

an old man with diabetes died after being infected with COVID-19.

A child died suddenly after a febrile convulsion.

so if things are bad, don't hold on.

if you have the following situations, go to the hospital non-stop.

07

what's the difference between ibuprofen capsule and ibuprofen sustained release capsule?

there are differences in efficacy.

Ibuprofen capsule (tablet) is mainly used to reduce fever.

ibuprofen sustained-release capsules (tablets) are mainly used to relieve pain, it has no or only weak antipyretic effect.

therefore, after infecting COVID-19, if you want to reduce the fever, you should take ibuprofen capsules (tablets).

want to relieve the pain of the bodyIbuprofen sustained release capsules (tablets) can be used.

if you are mistaken, use ibuprofen sustained-release capsule to reduce fever, the effect may not be good.

08

Why are antibiotics useless for novel coronavirus?

many people have a habit of "have a cold, take a cephalosporin", "have a sore throat, take an oxytetracycline".

but experts have repeatedly said that novel coronavirus is infected and it is useless to take any antibiotics.

that is to say, all kinds of cephalosporins, all kinds of mycin, all kinds of killer stars, all don't work.

is easy to understand.

bacteria, which are living organisms themselves, can multiply crazily as long as they are given a piece of meat or a piece of rice.

so after bacteria enter the human body, they all reproduce and wander outside the cells, and antibiotics can easily find it, destroy its structure, and kill it.

but the virus, which is hundreds of times smaller than bacteria, is not a complete life, and it has to drill into human cells before it can reproduce.

so as soon as it enters the human body, it drills into human cells.

antibiotics can't destroy human cells, so there's nothing you can do about the virus hiding in it.

09

what do you want to eat when you are positive?

after getting sick, don't just think about relying on ibuprofen to save yourself, and you mustn't be careless in strengthening nutrition.

how can you get better faster? there are mainly 6 points:

eat more food with soup after fever, pay attention to match with green vegetables;

A light diet, you can eat some shrimp, vegetables, porridge, etc., which are both light and nutritious.

supplementation of protein, milk, eggs and lean meat can improve immunity;

eat more fruits and vegetables and supplement vitamins;

abstain from greasy and spicy, when the intestines and stomach are fragile

, don't burden them;

Don't take antipyretic medicine on an empty stomach, it will stimulate our gastrointestinal tract.

10

my family is positive, but I am still overcast. What should I do?

find a separate room for your family and separate him.

his room should be independently windowed and ventilated every day, totaling more than half an hour.

Don't get in touch with him,

put the meal at the door of his room.

in the living room or bathroom where he has moved, you'd better wear an N95 mask.

while taking care of your family, don't forget to protect yourself.

11

if the family members are infected in a different order,

will the person who turns negative first be repeatedly infected?

No.

because after you are infected, your immune cells will remember the virus and produce antibodies that can defeat it.

when the virus comes again, the immune cells will immediately detect it and take out antibodies to kill it.

so there is nothing the virus can do about you in a short period of time.

it will take a long time

(for example, half a year)

, your immune system has forgotten what Omicron looks like, and all the antibodies made before have been consumed. If the virus comes again, you may be broken by it again.

12

do you use eliminate virus at home after Yangkang?

experts at The Temple of Earth Hospital in Beijing say that after "Yang Guo" recovers at home, the risk of being infected by household belongings is very small.

first of all, you have antibodies.

second, as we said earlier, viruses on the surface of ordinary objects will soon die at room temperature.

so you don't need a large eliminate virus from the inside out at home.

but the refrigerator needs to deal with it.

because in the refrigerator, whether it is 4 ℃ in the freezer or minus 18 ℃ in the freezer, it is very suitable for the virus to survive.

so you can unplug the refrigerator, wait until the temperature of the refrigerator is about the same as the room temperature, leave it for a day or so, and let the virus die.

13

when can I go out and return to work?

if you meet the following two requirements, you can basically return to work.

long sleeve trumpet wedding dress are eternal topic of fashion, which showcase your unique figure. Click and select your favorite dream dress.

1, body temperature returned to normal for more than 3 days;

2, the antigen was negative three times in three days.

at this time, the amount of virus in the infected person is so low that it basically does not infect people.

but although he has basically recovered, he has just experienced a great war, so don't be too tired.

work and exercise should be done step by step, giving the body some time to recover.

14

under what circumstances will the sun be restored?

generally, the antibody in vivo is maintained at a very high level 3-6 months after infection.

if you come into contact with O'Micron again, even a slightly mutated variety will generally be able to handle it.

however, if the virus has a big mutation, or if you encounter the same money half a year later, it is more likely to be infected again.

therefore, Yangkang can not be too arrogant, or to wear a good mask, do a good job of protection.

15

someone Yangkang two days later

it's positive again. What's going on?

it's not a secondary infection, but the previous virus in the body hasn't been cleared yet.

just because there is less virus in the body, it has not been detected before, and it seems to be negative.

but then various coincidences detected a little bit more, and it seemed to be positive again..

experts say this kind of person is not contagious, so don't be afraid of them.

that kind of thing is completely cured, and it will be infected again half a year later. It is really positive, so we have to be careful.

16

will the symptoms get worse after the second infection?

generally speaking, no.

if you are repeatedly infected with the same virus, the symptoms will be milder the second time.

because your immune cells have remembered what the virus looks like, the second time the virus comes in, you will be more experienced in dealing with it than the first time.

however, if the second infection is other mutated strains, it is hard to say.

or if you happen to be tired in the days of your second infection, or if your period visits, it is also likely to be a little heavier.

17

will repeated infection reduce a person's immunity?

there was a saying before:

the virus attacks the immune system, so repeated infection can greatly reduce a person's immunity.

this is wrong.

the reason is also very simple.

as we all know, after being infected with AIDS, people's immunity will get worse and worse.

that's because of HIV, which attacks human immune cells.

when immune cells are attacked repeatedly, people's immunity is bound to deteriorate.

but Omicron attacks a cell that exists mainly in our upper respiratory tract, not immune cells.

so even if we are repeatedly infected, it will not reduce our overall immunity.

it's gone!

that's all I can think of these two days.

if you think of other knowledge in a couple of days, I'll tell you about it.

strategists say that "know yourself and know the enemy, win a hundred battles and win a hundred battles".

We are now in an all-out battle with O'Micron, and we must know more about the characteristics of this guy.

Let's study hard together, strive for greater courage in the Vietnam War, and finally win in an all-round way.
