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.

2. How long have you been experiencing symptoms?
3. Are your symptoms getting better or worse?
