Human coronaviruses cannot be cultivated in the laboratory easily, unlike the rhinovirus, another cause of the common cold. This makes it difficult to gauge the coronavirus’ impact on national economies and public health.
There is no cure, so treatments include taking care of yourself and over-the-counter (OTC) medication:
Rest and avoid overexertion.
Drink enough water.
Avoid smoking and smoky areas.
Use a clean humidifier or cool mist vaporizer.
The virus responsible can be diagnosed by taking a sample of respiratory fluids, such as mucus from the nose, or blood.
