According to a new British study, public transit riders are six times more likely to suffer from acute respiratory infections. Only take the subway sometimes? Well occasional riders aren't safe either, in fact the study showed they are most at risk. Those who ride public transit everyday may build up an immunity to viruses, making the occasional straphanger the one to get sick more often.
The study followed 138 patients at a doctor's office, and compared their public transit habits with their frequency of getting sick. While the study was conducted at the University of Nottingham, far from our own MTA, it's a safe bet that it translates to every public transit system in the world... except Sweden, of course.
