Lab tests conducted by a group of Korean researchers revealed that when bacteria face the typical over-the-counter antibacterial ingredient known as triclosan for hours at the same time, the antiseptic formulation is a far more potent killer than plain soap. The problem: People wash their hands for a matter of seconds, not hours. And in real-world tests, the study team found no proof to suggest that normal hand-washing with antibacterial soap will any more to completely clean the hands than ordinary soap.For the study, Grijalva and his colleagues collected data on nearly 2,800 patients hospitalized for pneumonia in four U.S. January 2010 through June 2012 hospitals from. Approximately 6 % of these patients had flu-related pneumonia, while other patients were hospitalized for pneumonia that was not caused by influenza, Grijalva explained. ‘We compared the annals of influenza vaccination between these sufferers. We found that influenza vaccination was connected with a reduced risk of influenza pneumonia that needed hospitalization,’ he said. In the United States, annual flu epidemics send a lot more than 200,000 people to the hospital and kill as much as 49,000, according to the U.S. Centers for Disease Control and Avoidance.
