Cholera in Haiti is out of control

Cholera in Haiti is out of controlAccording to epidemiologist Sanjay Basu (Sanjay Basu) from the University of California at San Francisco (University of California, San Francisco), United States, World Health Organization (WHO) underestimates the extent of the cholera epidemic in Haiti, reports BBC News referring to the publication in a medical journal The Lancet. WHO estimates that the epidemic affected 400 thousand people, while independent researchers believe that this deadly disease can be affected twice as many people. According to them, in November 2011 in Haiti will be 779 thousand cases of cholera, and the number of deaths will be over 11 thousand
His conclusions researchers have analyzed the data provided by the Ministry of Health of Haiti. They say that the WHO figures are based on the assumption that the disease affects 4.2% of the 10 million people of Haiti. But they do not take into account additional factors such as the number of infected water sources and the level of immunity to cholera in the population. They believe that the WHO is not doing enough to stop the spread of the disease, not supplying clean water to all the places where it is infected, do not spend enough scale vaccination programs, and not all places ETC free access to antibiotics.
WHO denies these accusations, pointing out that all the measures needed to combat the cholera accepted. They point to the fact that their data on the number of cases and deaths do not conflict on earlier forecasts. Thus, by 10 March of this year in Haiti cholera 252.64 thousand. 4672 people died.
Cholera is one of the most dangerous and have not eradicated acute intestinal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. It has a short incubation period: sometimes less than a day, but usually about five days. Once ingested bacteria produce an enterotoxin that causes copious and painless watery diarrhea. In the absence of timely treatment, it can quickly lead to severe dehydration and death. Many patients also vomit.
According to one of the common points of view, to blame the outbreak of cholera in Haiti are the UN peacekeepers (the United Nations, UN) from Nepal. This view is based on a report by French epidemiologist Renaud Perroud (Renaud Piarroux), who concluded that the cholera originated in the tributary. Artibonite (Artibonite), Haiti, near the UN base outside the city of Mirebalais (Mirebalais). However, the report does not say directly to a specialist, the epidemic first started among soldiers. The UN has also refuted this version: the organization could not determine the source of the disease, but denies any involvement in this was.
By the way, in January 2011 in the journal PLoS Neglected Tropical Diseases, published an article alleging that the vaccination of the population benefits from cholera, even if it started after the outbreak. The authors of this article also suggests that the modern methods of dealing with a cholera epidemic should recognize ineffective.
