In Haiti, since the beginning of the cholera outbreak, starting epidemiological week (EW) 42 in 2010, until May 10th, 2011, the MSPP registered a total of 302,401 cholera cases of which 53.8% (162,651) required hospitalization and 1.7% (5,234) died (global case-fatality rate). Since EW 19 an increase in the number of new hospitalizations is observed in comparison with previous weeks, especially in the South-East and North-West departments and in the capital city, Port-au-Prince. Additionally, Artibonite and Centre continue to report new cases.
Since epidemiological week (EW) 16, the Dominican Republic’s surveillance system is registering an increase in the number of suspected cases of cholera, principally in the peripheral area of Santo Domingo, near the river Ozama and Isabela. The increase of cases in Santo Domingo concurs with a raise in the temperature and frequency of rains, which originated flooding in different areas of Santo Domingo.
