BELIZE:

Two new suspected cases of cholera have been reported although there is no further information at the moment. Both cases occurred in Saint Martin Village (Cayo district) and have been hospitalized in Belmopan. All three rivers in the Cayo district on the Guatemala border have reported that water samples tested positive for the cholera virus. These rivers: Tencent Creek near the capital, Roaring Creek, and the Mopan River all originate in Guatemala and cross through Belize. This puts an estimated 90,000 persons who live in 20 towns along the rivers at risk. The cumulative number of cases to date is five, with one death.

EPIDEMIOLOGICAL ANALYSIS NOVEMBER 26, 1998

Epidemic activity of cholera remains in the five affected countries. Guatemala has reported increases in the last three weeks and has the highest risk.

Epidemic activity of leptospirosis also remains, principally in Nicaragua, with low reporting in Honduras and Guatemala.

There is epidemic activity of dengue in Guatemala, Honduras, Nicaragua and El Salvador. Honduras reports cases one death from hemorrhagic dengue.

PAHO continues to recognize the efforts made by the affected countries to control the occurrence of epidemics.

The cholera situation in Guatemala is the most important epidemiological phenomenon in the subregion at the moment because of the risk it poses not only internally but also to neighboring countries should it spread. Therefore, PAHO reiterates the need to improve the epidemiological surveillance systems with regard to early detection and control of outbreaks that could erupt en any neighboring country.

With regard to cholera, PAHO recommends the prevention and control measures mentioned previously:

  1. Strengthen health control measures, including basic hygiene measures, provision of safe water, and handling and consumption of food from street vendors, among the at-risk population, particularly in shelters.
  2. Intensify local epidemiological surveillance measures of cholera (active identification of cases) in the affected population.
  3. Implement social communication campaigns particularly in shelters and among the displaced population and indigenous communities.
