As usual, I assume the discrepancy is due to late reports from some departments. No one, neither MSPP nor PAHO nor OCHA, has ever explained the reasons for this erratic reporting. (I see PAHO has not bothered to update its deeply uninformative Haiti blog since October 17.)
So we now have a total of 638,217 cholera cases since the outbreak began in October 2010, and 7,939 deaths—27 of them in the first six days of 2013.
As usual, neither MSPP nor anyone else has issued a news release or offered an interview to explain and analyze the continuing disaster.
