Persistent positivity after COVID-19 diagnosis?
Hello Doctor: I tested positive on November 9 and started taking molnupiravir, completing a five-day course.
After that, the second line on the test strip became faint, but the next day it started to darken again.
As of today, November 18, the second line has been getting darker with no signs of fading.
However, I do not have any unusual symptoms, and I am not experiencing any cough or pneumonia symptoms; everything feels normal.
My question is, does this ongoing situation have any implications? Do I need to isolate myself from my family? I have hepatitis B, but my test results have been normal every three months.

Patients with complications from COVID-19 require isolation.
It is recommended to wear a mask and monitor for any worsening symptoms.
You may discuss with your original physician, and if you experience any discomfort or have questions, please consult the infectious disease outpatient clinic at the hospital.

Persistent positive COVID-19 test results can be a source of confusion and concern, especially for individuals who have already undergone treatment and are not experiencing any symptoms. In your case, having tested positive for COVID-19 on November 9 and subsequently taking molnupiravir, it is understandable to be worried about the implications of a continuing positive test result, particularly when the second line on the test strip remains prominent.
Firstly, it is important to understand that the presence of viral RNA, as detected by PCR tests or rapid antigen tests, does not necessarily correlate with infectiousness. Many individuals can continue to test positive for several days or even weeks after the initial infection, even when they are no longer contagious. This phenomenon can occur due to residual viral particles that remain in the body after the acute phase of the infection has resolved. In fact, studies have shown that individuals can continue to test positive long after they have recovered from the illness, particularly if they had a mild case or were asymptomatic.
Given that you are not experiencing any symptoms such as cough, fever, or difficulty breathing, it is likely that your body is managing the infection effectively. The fact that you have been treated with molnupiravir, an antiviral medication, suggests that your healthcare provider is taking steps to mitigate the severity of the infection. However, it is still advisable to follow public health guidelines regarding isolation, especially if you are living with others. The Centers for Disease Control and Prevention (CDC) recommends that individuals who test positive for COVID-19 should isolate for at least five days, regardless of symptoms, to prevent potential transmission to others.
Regarding your hepatitis B status, it is good to hear that you are regularly monitoring your liver function and that your results have been normal. Hepatitis B can complicate the clinical picture in cases of COVID-19, but as long as your liver function tests are stable, it should not significantly impact your COVID-19 recovery. However, it is essential to keep your healthcare provider informed about your hepatitis B status, as they may need to monitor you more closely during this time.
In summary, while a persistent positive COVID-19 test can be concerning, it does not necessarily indicate that you are still infectious, especially in the absence of symptoms. It is prudent to continue isolating from others until you have completed the recommended isolation period and to maintain open communication with your healthcare provider regarding your condition. If you have any new symptoms or concerns, do not hesitate to seek medical advice. Your health and the health of those around you are paramount, and following guidelines will help ensure everyone's safety.
