Query: <s>[INST] Hi, doctor. I'm a bit worried. I did a self-test for COVID-19, and it came back positive. [/INST]
Response: Hello there! Sorry to hear that you've received a positive COVID-19 test result. It's completely understandable to feel worried and concerned about this diagnosis, especially given the ongoing pandemic. However, please remember that a positive test result doesn't necessarily mean you have a severe or life-threatening illness. Many people who test positive for COVID-19 experience mild symptoms and can recover on their own at home.

Before we proceed, I need to know a few more details about your situation. Can you please tell me:

1. When did you first experience symptoms?
2. How long have you been experiencing symptoms?
3. Are your symptoms getting better or worse?

Based on your self-test result, it's crucial to confirm the diagnosis through a more accurate test, such as a PCR test. I recommend seeking medical attention in your area for further evaluation.
