In response to the Latin American cholera epidemic, El Salvador began a prevention programme in April 1991.
The first case was confirmed in August, and 700 cases were reported within 3 months.
A matched case-control study was conducted in rural La Libertad Department in November 1991.
Illness was associated with eating cold cooked or raw seafood (odds ratio [OR]=7.0 ; 95% confidence limits [CL]=1.4,35.0) and with drinking water outside the home (OR=8.8 ; 95% CL=1.7,44.6).
Assertion of knowledge about how to prevent cholera (OR=0.2 ; 95% CL=0.1,0.8) and eating rice (OR=0.2 ; 95% CL=0.1,0.8) were protective.
More controls than patients regularly used soap (OR=0.3 ; 95% CL=0.1,1.0).
This study demonstrated three important points for cholera prevention :
(1) seafood should be eaten cooked and hot ;
(2) populations at risk should be taught to treat household drinking water and to avoid drinking water outside the home unless it is known to be treated ;
and (3) education about hygiene can be an important tool in preventing cholera.
