Every winter, when there is a growing incidence of influenza and SARS, and the office is full of coughing and splashing saliva workers, the recommendations of doctors are, as a rule, regular hand washing. They say that it prevents the transmission of viruses and pathogens. American scientists from the National Institute of health in Bethesda managed to establish the importance of another point - you can not touch your face.
According to Thе Dаily Mail, touching the nose or mouth, the person contributes to the instantaneous transmission of bacteria and viruses from the hands. According to Dr. Vladimir Alonso, handwashing is powerless, after all, a million possibilities of infection from bacteria pursue a person every second.
To verify this statement were invited 249 people tracked while they are visiting public places in Washington (district of Columbia) and florianópolis (Brazil). It turned out objects touch people produced an average of 3.3 times per hour, face - 3.6 times per hour. This shows the danger of this habit. Therefore, with high probability, the person on the hands of microbes will be faster than it will wash away.
On the other hand, the human body is protected from pathogens by the immune system. Therefore, unreasonably DC voltage due to possible contamination. However, when there is an epidemic of flu and norovirus, keep your hands.
