As cholera returns to Haiti, blame is unhelpful

"(...) the strain of Vibrio cholerae seems to be a south Asian strain, and Nepalese aid workers in the region have been implicated as the source, leading to protests against their presence and some people calling for them to leave the country (...) Although interest in how the outbreak originated may be a matter of scientific curiosity for the future, apportioning blame for the outbreak now is neither fair to people working to improve a dire situation nor helpful in combating the disease," wrote The Lancet Infectious Diseases in December 2010.
