Dear Sir/Madam, I am writing to seek for the opinions from Covid-19 expert. I hope that I will receive the answers to my questions. I have got the reinfections of Covid-19 at the beginning of July after my first infection last July. Per my understanding, there is less than 20% of people to be infected twice or more. I still wear mask most of the time when I go outside except when I have meals or hike. Therefore, I am very upset to know that I am infected again. I started to have uncomfortable throat on July 04 (Day 0). Today is Day 9 and my rapid test is negative. Nevertheless, I am still very unhappy and I have a series of questions in my head. Would you answer my following questions. (1) My first infection took 7 days to recover and got negative result. I have searched via internet and found that people take shorter time to recover from reinfection. On the other hand, I take longer time. I do not have severe symptoms both time and I even do not have fever. Do you know when this time I take longer time to heal? (2) To provide more information, for rapid test, this time there was 1 more day of dark color T-line (4 days last time vs 5 days this time). On Day 7 morning, the color of T-line changed from dark color to very very light color (nearly unseen). It looks like that I am recovered. However, when I used another brand of rapid test kit for the test that evening, the T-line was clear though it was not dark. I was very depressed at that moment. Is it normal that the color of T-line will come back? (3) On Day 8 morning, the rapid test showed again the color of T-line was very very light (nearly unseen) which was the same as Day 7 morning. I have no idea why the results were the same On Day 7 and Day 8. I used another brand to test on Day 8 evening, the color of T-line was also very hard to see until I looked carefully. This is very strange to me. I know some other people infected by Covid-19 too. They have the negative test result if there is a light color of T-line the day before and it is also the case of my first infection. Could you explain why I take longer time at this stage this time? I am very worried that my immunity system has problem. (4) On Day 7, I started to have some muscle pain on my thighs. I did not have this symptom last time. I have checked via internet and note that this symptom is rare. However, one of the reasons of this symptom is blood clot in the blood vessels. Would you suggest if I should see a doctor immediately? It looks like the pain is still there but lessened now but I am still worried. Would you give me your opinions? For you information, I have got 3 doses of BioNTech vaccine before my first injection. There is saying that the new variants of Covid-19 are less dangerous but I read some posts that it still risky to health, especially to some organs. In addition, the risk is higher when it is reinfection. My worry is the least when I know that I am reinfected. However, the steps of my recovery mentioned and the leg muscle pain really make me very concerned. I hope that I can get the opinions from the professionals to let me understand more about my situation. Sorry for this long message but I really need to have the answers to my questions as I am in high stress now. Should I need to take any other actions, please let me know. Thank you in advance.
The fact of being in good health does not prevent risk of contracting Covid. WearThe available antigen test kits have variable sensitivities in detecting SARS-CoV and are susceptible which type of sample is being tested (throat swab, nasal swab, deep nasopharyngeal swab, saliva, etc.), whether the test kit is expired or near expiration (plus whether the test kit has been stored in a cool dry location vs. a hot or humid location), and other factors. So, testing with different kits on different days and getting a strong or less strong positive isn’t as important as maintaining an attitude that you may continue to be shedding viruses and thereby continue to be infectious to other people. Many people don’t have the luxury of being able to have access to or be able to afford test kits or multiple test kits. I am glad that you have been vaccinated and even though it does not guarantee that you will not get infected, it does decrease your risk of serious infection, complications, hospitalizations or death. I would continue to isolate at home and minimize your interactions outside of the home (less frequent and only for short durations). Whenever you leave home, you should wear a well-fitting mask (such as a KN95 mask) to reduce the chances that you can spread the infection to other people. I would continue this for the next 10 days. If your leg pains return or you have other muscular pain then I would call your doctor for further instructions.
