Haiti: The Progression Of An Epidemic

 

 

# 5108

 

 

A truly illuminating look at the relentless spread of cholera in Haiti comes today via a series of maps released by OCHA that show the geographic and numerical case load progression of the illness from October 20th through November 29th.

 

As with most epidemics, the increases in the beginning are small, but they quickly explode.

 

Some of that may be due to limited surveillance and reporting during the first couple of weeks.  But as more and more people become carriers, the actual spread of the illness accelerates rapidly.

These are just reported numbers, of course. The real numbers are likely much higher.   Also, a great many more people are assumed to be asymptomatic carriers of the bacteria.

 

A series of maps shows how this outbreak started in one department (Haiti is divided into 10 Departments), and in a matter of a couple of weeks spread to 5, then 7, and finally all 10 departments.
