Recommendations

In December last year, the WHO deployed a Rapid response team to the South-West (Ekondo Titi) and Centre region. Rapid diagnostic test kits and sample transportation media have also been deployed to the affected regions.A cholera treatment unit (CTU) of 14 beds was set up in Bamusso Health Centre and treatment guidelines have been developed with support from MSF. Also, Cholera case management kits were distributed in health facilities; with free treatment, Community leaders and selected community members have been trained on hand washing, purification of water and disinfection of homes and public spaces amongst others

A response plan has been elaborated and the Ministry of Health with health partners including WHO, UNICEF and Doctors without borders will support the different areas of the response plan.

As of now, teams from the Ministry of public health are creating awareness on the disease, the objective of which is to educate people on the basic rules of hygiene, starting with systematic hand washing. This sensitization also involves the construction of latrine blocks to stop the spread of the epidemic. “vaccination is expected that vaccination will come after the sensitisation. 

Cholera outbreaks are recurrent in Cameroon, especially in areas known for having poor drainage systems and sanitation facilities. In addition to poor sanitary conditions, Public Health experts say ignorance about the disease is one of the key reasons why there is a resurgence so often.
