If one has symptoms of covid 19 namely:

1. Scratchy throat
2. Dry throat
3. Dry cough
4. High temperature
5. Respiratory problem
6. Lose of sense of smell and taste

- quicky take hot water with lemon and drink, may also gurgle warm water with salt, as the virus stays in throat for days before going down to the lungs. (Tips from my professor, a medical expert)
