I believe that everyone has brushed this picture:
On January 4, the new crown in the United States added 1.02 million in 25 hours, and when domestic netizens ate melons, I can only say: people in the United States have experienced it.
In the past month and a half, several friends around me have been infected with the new crown, and I myself have been on the road to close isolation, nucleic acid testing and being closely connected every day. If you are panicking over Amikeron, I hope my sharing will help you.
The Rapid Test, also known as the antigen test, detects proteins that cause the coronavirus. After the emergence of COVID-19 symptoms, this test is the fastest and most convenient, can be purchased in major supermarkets and pharmacies, and our school can do it for free.
However, the results of this test are not necessarily accurate, and there is a certain probability of false positive results, ranging from 34.1% to 88.1%, depending on the brand. In addition, the local epidemic situation will also affect the probability of false positives. For example, a positive Predictive Value (PPV) test of 80% has a 20% false positive when the population infection rate is 10%, that is, 20 out of 100 positive results are actually negative, of course, if there are symptoms, the false positive may be much lower.
I'm a living example. Two months ago, I had dinner with my brother A, and when I ate, I was still saying that I felt that the school epidemic prevention and control was doing quite well, so far it felt as if it was not very serious, and as a result, the little brother was drawn to the random Rapid Test the next day after he went back, and he was positive. And as his close confidant, I quickly began to self-isolate: please ask my roommate to go out first, and prepare a lunch box to eat from the canteen later, and then go back to my room to eat. When I had sorted everything out, the next morning Brother A and I sent WeChat saying: I just tested again, it is negative.
All I can say is that the Rapid Test is too bad! Later, he tested again and was still negative and had no symptoms, and we were relieved to be sure that the first time was a false positive.
How easy is it to be a close connection in the United States? During the self-isolation period, I met the old man who lived in the hallway and greeted me. I said, "Big brother, stay away from me, I'm a close contact." He said: "It's okay, I'm also close to (another meal), I've had a fever for three days, and the school doesn't have a test kit yet." I squeezed out a stiff smile and told him good luck, and I just wanted to run back to my room quickly, and sure enough, I heard the news that he was positive the next day.
Every school's quarantine policy is different, but most follow the U.S. Centers for Disease Control and Prevention (CDC) guidelines for epidemic prevention and isolation.
In our school, for example, if you accidentally become a close contact, the school requires you to self-isolate for 5 days from the day of contact and wear a mask for 10 days after that. People who have been fully vaccinated do not need to be isolated, but must wear masks indoors and in public places.
In addition, regardless of whether there are symptoms or not, it is important to do the test on the 5th to 7th day of contact with the patient. Because the virus has an incubation period, there is a period of time from contact with the patient to the onset of symptoms. It is advisable not to eat with others during this time, because if you test positive, the person you come into contact with will become a close contact. Of course, school rules are not necessarily the strictest, but if you want to better protect the people around you, it is best to stop contacting once you feel that you are at risk.
Once, I got a text message from a friend saying that two of the people I ate with five days ago were both true positives with symptoms, but I never got an email from the school that I was a close contact. Later I thought about it, maybe because the test result is more than five days away from the meal, so the school thinks it is not a close connection, which may be placed in China may be direct ambulance pulled away of the close connection it... In order to ensure that nothing was wrong, I still self-isolated, and after two days to test twice negative, which lifted the isolation.
After about a week or so, Brother B returned from New York. At that time, the epidemic in New York was already very serious, and at the strong request of his roommate, he tested negative at the Airport in New York. So the night he came back we had a happy meal together. The next afternoon, Brother B's roommate sent a message saying that Brother B had a fever and suggested that we self-isolate first - and then the two of them were close. This time, I finally received an email from the school informing me that I was a close contact, and I was also afraid, after all, it was the first time to meet the American close connection standards. It was so close to eating that he had a fever the next day. So in fear, I locked myself in my room and ate instant noodles for a few days, checking my temperature every day, fortunately I passed the isolation period safely and did not have infection.
Although it is said to be a close connection, it is not necessarily infected. When the patient informs that he is a close contact, it is best to say thank you and then express concern/comfort, no one wants to get sick or intends to contact you. Even if you really have a broken mentality, on the surface, you must remain decent and stop putting pressure on the patient.
If you become a close contact yourself, or have suspected symptoms, I have two tips to share with you:
Ensure that your work and rest are regular and healthy: you should eat and sleep, and don't collapse your body because of panic. Sometimes you may feel uncomfortable or have symptoms similar to COVID-19 due to psychological stress or other physical reasons.
On the third night of the close connection, I was lying in bed and suddenly felt difficulty breathing. The school said that the breathing difficulty was to directly hit the symptoms of 911, but I thought about it and thought about not coughing or fever, so I wouldn't make a big one as soon as I came. After thinking about it for five minutes, I suddenly remembered that I had asthma, and the symptoms of chest tightness and breathing difficulties were exactly the same as asthma, so I first took asthma medicine, and after a while it was relieved.
Vaccinations: Most of the infected people I know are not vaccinated, and although they cannot prevent infection 100%, they can at least reduce the rate of severe illness.
Although I tested negative three times at the end of the quarantine, the continuous close contact during this period really made me realize the seriousness of this wave of epidemics. In addition to the data released on the official website, the circle of friends has also been brushed to positive, and I really feel that the epidemic is very close to me. Now that the school starts, I don't dare to eat with others, and the food in the canteen is packed back to the room to eat, and I have to wear a mask when I go out to the toilet. The school head iron continues to take offline classes, and the isolated room is not enough, I hope I can hold on!
