Most of the toilets at these courts are not well cleaned, the report said the study's authors. Even seemingly quite strict sanitation program of the Center for Disease Control and Prevention (CDC) could not identify the dirty toilets.
According to the official report, CDC, the cause of all of these diseases have become "unidentified sources of pollution", which led to the spread of norovirus (in the United States this disease is also called stomach flu ). However, as a rule, cruise ships do not have problems with cleanliness, all their facilities are strict sanitary inspection and to a high standard. Curiously, the ships, which were recorded outbreak of norovirus infections, assessment of the sanitary condition was higher than those courts where these diseases were not.
Obviously, the commissioners rarely looked into the toilets. Noroviruses can survive at room temperature for several weeks, they are very hard to kill. "It's a heavy virus, - says study author Dr. Philip Carling. - Just a doormat you do not destroy it. The only thing he fears is chlorine."
During the study, the toilets were tested on 56 cruise ships. The authors of the study marked with a special compound, visible only under ultraviolet light, doors, toilet seats, levers for lowering water krantik in shells and other areas in the dressing room, to which the human hand can touch.
A week later, the toilets tested to verify whether the cleaners washed the solution (the consistency similar to a virus). Only four ships, as it turned out, latrines thoroughly washed every day. And in the toilets of 63% of ships following solutions still preserved in any kind of surfaces.
