UV lamps inactivate a coronavirus in 10-12 minutes.

The disease is proceeding. usually without a rise in temperature.

 

The main symptoms are a profuse runny nose, but along with it there is a defeat of other parts of the respiratory tract, including inflammation of the pharynx, cough, fever and general intoxication with a headache.
