COVID-19
Hello, doctor.
I have a question to ask you.
Currently, my parents, sister-in-law, and niece were diagnosed with COVID-19 seven days ago, and I live with them.
About four days ago, I started experiencing symptoms, initially mild sneezing and a runny nose.
The rapid test on that day was negative.
Two days later, I developed mild sore throat and cough symptoms, and the rapid test was still negative.
So far, I have not experienced any severe symptoms, and everything has been quite mild.
I would like to know what could be the reason for having symptoms but testing negative on the rapid test? Does my situation indicate that I have been infected? If I have symptoms but test negative, can I take over-the-counter medication for the mild sore throat?

Hello: Based on your description, your likelihood of being infected is quite high.
As for why both rapid tests came back negative, you may want to consider the following three possibilities: 1.
Testing issues: Each test can be affected by variations in the sampling technique, which can influence the interpretation of the results.
2.
Low viral load: Since you are currently experiencing symptoms, it is unlikely that a low viral load is due to being in the incubation period.
Another possibility is that you may have been previously infected, and your body has developed antibodies, resulting in a lower viral load.
3.
No infection.
In summary, it is recommended that if possible, you perform a rapid test daily.
If you continue to test negative after 7 days, you can feel more reassured.
Additionally, if you have significant concerns about being infected, you may consider visiting a healthcare provider for a PCR test.
Most individuals who are infected manage their symptoms with medication, allowing the body to recover naturally; the medications primarily aim to make this process more comfortable.
Only certain populations, such as the elderly or those with chronic illnesses, may be prescribed antiviral medications.
Therefore, using medication to alleviate your sore throat symptoms is acceptable, but be aware that over-the-counter medications often have more complex ingredients, which raises concerns about potential side effects.

Hello! Thank you for your question regarding your symptoms and negative COVID-19 test results. It’s understandable to feel concerned, especially given your close contact with family members who have tested positive. Let’s break down your situation and address your concerns.
1. Understanding Negative Test Results with Symptoms: It is indeed possible to have symptoms of COVID-19 and still test negative on a rapid antigen test. This can happen for several reasons:
- Timing of the Test: Rapid tests are most effective when the viral load is high, typically around the time symptoms first appear. If you tested too early or too late in your infection, the test may not detect the virus.
- Viral Load: If your body is not producing a high enough viral load at the time of testing, the rapid test may return a negative result, even if you are infected.
- Test Sensitivity: Rapid antigen tests are generally less sensitive than PCR tests. They can miss infections, particularly in asymptomatic individuals or those with mild symptoms.
2. Are You Infected?: Given that you live with individuals who have confirmed COVID-19, and you are experiencing symptoms, it is reasonable to suspect that you may have been infected, even if your rapid tests are negative. The presence of symptoms, especially after exposure, suggests that you should consider yourself a potential case of COVID-19.
3. Next Steps:
- Continue Monitoring Symptoms: Keep an eye on your symptoms. If they worsen or you develop new symptoms, it may be wise to seek further medical advice.
- Consider PCR Testing: If you have access to a PCR test, it may provide a more definitive answer regarding your COVID-19 status. PCR tests are more sensitive and can detect lower levels of the virus.
- Self-Isolation: Since you have symptoms and have been exposed to confirmed cases, it is advisable to self-isolate to prevent potential spread to others until you can confirm your COVID-19 status.
4. Over-the-Counter Medications: For mild symptoms like a sore throat or cough, over-the-counter medications can be used to alleviate discomfort. Common options include:
- Pain Relievers: Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) can help reduce pain and fever.
- Throat Lozenges: These can soothe a sore throat.
- Cough Suppressants: If your cough is bothersome, consider using a cough syrup or suppressant.
5. When to Seek Medical Attention: If you experience any of the following symptoms, seek medical attention immediately:
- Difficulty breathing or shortness of breath
- Persistent chest pain or pressure
- New confusion or inability to stay awake
- Bluish lips or face
6. Emotional Well-being: It’s also important to take care of your mental health during this time. The uncertainty and concern surrounding COVID-19 can be stressful. Make sure to reach out to friends, family, or mental health professionals if you feel overwhelmed.
In summary, while your negative rapid tests are concerning, your symptoms and recent exposure suggest that you may still be infected. Continue to monitor your health, consider getting a PCR test, and manage your symptoms with over-the-counter medications as needed. Stay safe and take care of yourself!
