  1. Epidemic cholera in rural El Salvador : risk factors in a region covered by a cholera prevention campaign.

    Article - En anglais

    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.
