I have a diarrhea, fatigue, chills. is it necessary that i consult a doctor?

That would be prudent. COVID 19 sx’s: dry cough, shortness of breath, chest tightness, nasal congestion, sneezing, fever, headache, sore throat, feeling tired, loss of sense of taste/smell, decreased appetite, nausea, diarrhea, vomiting, chills & muscle aches.

I agree this can a flu-like syndrome-like COVID 19. Keep isolated. If you are not urinating, feel dizzy, have chest pain or shortness of breath see a doctor right away. You can try telemedicine
