Based on findings of a recent study researchers say people aren't the only organisms traveling around the world but also is infectious diseases .
Previous studies conducted among air travelers, including those involving the spread of tuberculosis on planes. Results suggest sitting within two rows of a contagious individual during a flight lasting longer than eight hours places passengers at risk of getting the disease. Another study that examined transmission of SARS during air travel found sitting up to seven rows away could result in infection. Thus researchers say their evidence points to more frequent recirculation of cabin air.
Some studies in the past have indicated that doubling the air exchange could cut the infection risk from tuberculosis in half and using disinfectants to clean the cabin between flights to areas of the world prone to malaria and other vector-borne diseases can help reduce disease transmission.
Thus in conclusion researchers suggest that simple measures such as frequent hand washing, which has been proven to reduce the transmission of airborne and other infectious diseases be followed by passengers and they also urge the use of HEPA filters on airplanes to further reduce the risk of transmission of infectious diseases.
