2009 Guinea Bissau: Evaluation of cholera Surveillance System in Guinea Bissau

Executive summary


Cholera is an endemic disease in Guinea Bissau and cholera outbreaks occur with inter-epidemic periods of different length.  The national cholera surveillance system is crucial for a rapid detection of cholera cases and prompt detection of outbreaks that will enable a quick control of the epidemic.

We proposed to develop and evaluation of the cholera surveillance system in Guinea Bissau in order to make recommendation that may be used to improve the current system and the preparedness and response to cholera epidemics.


The purpose of evaluating the cholera surveillance system of Guinea Bissau is to ensure that this disease, of public health importance, is being monitored efficiently and effectively.  Evaluation of a public health surveillance system focuses on how well the system operates to meet its purpose and objectives, and it may improve the information provided to ensure that cholera is being monitored efficiently and effectively.

The specific objectives of this evaluation were to (a) describe the importance of cholera in Guinea Bissau and the relevance of a surveillance system, (b) describe the purpose and procedures of the cholera surveillance system, and (c) detect items to be improved in the attributes of the cholera surveillance system.


With the aim of meeting the above objectives, the following sources of information were used:

a. Administrative data: national guidelines, paper forms, electronic files and other documentation.

b. Primary data collection: information obtained through semi-structured interviews and focus groups.

c. Secondary data collection: previous reports, scientific articles, manuscripts, etc., regarding cholera surveillance in Guinea Bissau.

Findings and Conclusions:

The Integrated Surveillance System for Diseases and Responses, and specifically the cholera surveillance system, has accomplished many achievements:

  • The network of community health workers is very useful tool in the detection of cases there where the health system faces difficulties
  • The users of the surveillance system are aware of the importance of high quality surveillance activities and the prompt identification of cases
  • During 2009, The Ministry of Health, with the support of partners, called for the implementation of a study that analyzed the causes that determine the occurrence of cholera in Guinea-Bissau.
  • The MPH has also been recently involved in the preparation of its 2nd National Health Development Plans (PNDS II) in order to adapt the previous version of the National Strategic Planning for Poverty Reduction.
