Summary
Cameroon identified 48 priority districts for cholera control interventions between 2016-2023. These areas, representing 24% of districts, experienced over 91% of cholera cases, highlighting urgent needs for multisectoral action.
Area of Science:
- Public Health
- Epidemiology
- Infectious Disease Control
Background:
- Cholera remains a significant public health challenge in Cameroon.
- Effective cholera control requires targeted, multisectoral interventions.
Purpose of the Study:
- To identify priority areas for multisectoral interventions to control cholera in Cameroon.
- To guide resource allocation for cholera preparedness and prevention.
Main Methods:
- Data on cholera cases (2016-2023) were collected from national sources.
- A priority index (incidence, mortality, persistence, test positivity) and vulnerability index were calculated.
- Districts were categorized as priority areas based on these indices and vulnerability factors.
Main Results:
- 48 out of 200 health districts (24%) were identified as priority areas.
- These districts accounted for 91.3% of all reported cholera cases (2016-2023).
- Centre, Littoral, South-West, and Far North regions contained 85.4% of these priority areas.
Conclusions:
- The identification of priority areas provides crucial evidence for decision-making in cholera control.
- Data availability and governmental stakeholder leadership are essential for effective cholera preparedness and prevention strategies.

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...

42
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
