The source of energy that the virus relies on to move from one person to another is the potential energy that is present in high concentration, thus it diffuses easily when moved from a high concentration site to a low concentration site. This movement is spontaneous and entropy driven. Therefore, the virus is strong when it is gathered and weak when it is dispersed. Moreover, it is known that the dose determines the toxicity, and in the case of the coronavirus, the larger the viral load, the greater the chance for infection. That is why social distancing and wearing a mask is a practical approach to prevent diseases.Â
