Abstract
The coronavirus disease 2019 (COVID-19) has recently spread worldwide due to the SARS-CoV-2 virus and has been declared a pandemic. A possible solution to prevent or restrict the spread of the COVID-19 pandemic is proposed in this article. Uncontrolled spread of the virus through breathing is a major concern. It is ideal if the entry of the virus inside the human body is restricted, as prevention is better than cure. Use of a “Smart-HELMET” that allows uncontaminated air (virus/bacteria/microbes-free) to breathe is proposed. The design of the Smart-HELMET, its working mechanism, the chemistry and biology of the virus-cell interaction inside a human body are discussed in detail. The proposed ‘Smart-HELMET’ prevents the spread of any respiratory illness through breathing. This is the need of the hour until a medicine/vaccine is made available in in vivo condition.
