Although the novel coronavirus can infect anyone, evidence suggests that certain groups like older adults and those with underlying medical conditions are at higher risk for contracting COVID-19. Cases from wuhan, china where COVID-19 originated, shows that people who were diagnosed with cardiovascular diseases and respiratory diseases due to tobacco use were at a higher risk of developing severe COVID-19 symptoms.Transmitting the virus from the hands to the mouth is the most common way of getting the disease.
Dr Nilesh Shah, Group President, Metropolis Healthcare Ltd, mumbai told "Chain-smokers likely to be vulnerable to Covid-19 due to enzyme ACE2. A study by Chinese doctors on 99 patients affected by COVID-19 found that chain-smokers were more at risk of dying".
According to World health Organization, smoking can increase risk due to behavioral factors because smokers constantly put their fingers to their lips when holding a cigarette, thereby transporting germs from their hands to their mouths. Transmitting the virus from the hands to the mouth is the most common way of getting the disease. Further, smokers may also share cigarettes which again increases the chances of spreading germs", says Dr Shah.
