The Covid-19 pandemic has thrown up a very important question - should we stop shaking hands for good? A group of scientists, who has published their study in the Journal of Dermatological Science, agrees. Hands constantly connect our microbiome to the microbiomes of other people. They are 'critical vectors' for transmitting microorganisms including viruses, scientists wrote. According to Charles Gerba, a microbiologist and public health researcher at the University of Arizona, every time you touch a surface, you may be picking up about 50% of the organisms. While concerns about Covid-19 grew, many international personalities were seen shifting to the desi 'namaste'. As these experts suggest, perhaps it is end of the handshake.
