Smokers, Vegetarians Have Far Less Chance of Contracting COVID-19: Survey
Smokers and vegetarians were found to have lower seropositivity indicating that they may be at a lesser risk of getting infected by coronavirus, according to a Pan Indian serosurvey conducted by the Council of Scientific and Industrial Research (CSIR). The survey was conducted across CSIR’s nearly 40 institutes.
The survey also found that those with blood group 'O' may be less susceptible to the infection, while people with 'B' and 'AB' blood gr
oups were at a higher risk. For its study, the Council of Scientific and Industrial Research (CSIR) took samples of 10,427 adult individuals working in its laboratories or institutions and their family members, based on voluntary participation, to assess the presence of antibodies to SARS-CoV-2.
The study which was piloted by CSIR-Institute of Genomics and Integrative Biology (IGIB), Delhi said of the 10,427 individuals, 1,058 (10.14 per cent) had antibodies against SARS-CoV-2. A follow up on 346 seropositive individuals among the samples after three months revealed stable' to higher' antibody levels against SARS-CoV-2, but declining plasma activity for neutralizing the virus, Shantanu Sengupta, senior scientist at IGIB and one of the co-authors of the paper said.
“Our finding that smokers are less likely to be seropositive is the first report from the general population and part of growing evidence that despite COVID-19 being a respiratory disease, smoking may be protective,” the study said.
The paper also cites two studies from France and similar reports from Italy, New York and China, which reported lower infection rates among smokers.
