Cholera Background History:
The first cholera outbreak was reported in 1978. Between 1978 and 1996, no cholera case was reported.
The first major outbreak occurred in November 1997 and continued until July 1998. Cumulative number of cases and deaths notified during those ears are illustrated in the table. The first cases reported in November 1997 occurred in the districtof Pointe Noire in the region of Kouilou (southernpart of the country, bordering Angola).
From November 1997 to February 1998, the case fatality rate was very high (20%). Four areas in the city of Pointe Noire were, affected, the worst being Arrondissement III and IV where water,quality and sanitary conditions were extremely poor.
Cholera outbreaks have also been reported from the districts of Madingo-Kayes and Kakamoeka both neighbouring Pointe-Noire in the Kouilou region. Unfortunately exact figures forthese areas are not available.
In March 1999, cholera cases were confirmed in the capital city of Brazzaville but further information is not available.Cases had already been reported since December 1998 but additional information is not available.
2006-2007: In December 2006, a large outbreak hit the country, affecting 7 098 people including 101 deaths over a period of 5 months (the affected areas spread and epicurve are illustrated on page 2). Again the index case was reported
in Pointe Noire and occurred during the rainy season (October to May). The outbreak had potentially spread from neighbouring Angola, (Cabinda province). It cannot be excluded that a similar pattern occurred in 1997, since Angola
reported 1306 cases and 42 deaths in 1996, but no case in 1997.
In 2008, a cholera epidemic occurred in Loudima district, in the Bouenza division which is located 375 km South-East of Brazzaville. Cases have also been registered in the neighbouring villages Houdin (2 cases on 19 July), Sibiti (1 case on 29
July) and Madingou (1 case on 30 July).
