For common people, two presentations (1. Master_Slide and 2. Paper_Presentation ) from the supplementary section (at the end of the paper) are important, especially the Master_Slide.

Few of the solutions mentioned are:

Portable Convector Room Heater: Stay close to a convector room heater and inhale hot air at least two times a day for around 20 minutes to half an hour each time (keeping comfort level). It would be very useful at the initial stages of the disease.  

Hot Drinks: For very mild symptoms, take hot drinks (could be tea, coffee, warm milk, hot water with lemon etc.) few times a day to destroy virus in the mouth and throat. Gargle with warm salt water at least three/four times a day will be very beneficial. Hot soup will also be useful.

Why: The virus is very sensitive to Temperature. It initially accumulates in the nasal cavity and back of the Mouth and testing is done with swabs from those places.

At the initial stages of the disease, only even Convector Room Heater, Warm Salt water gargle and Hot drinks can serve the main purpose!
