Rapid Response to a Cholera outbreak in Hodeidah governorate, Yemen 2010.

Introduction: Cholera remains a health problem in many parts of the word. Refugees, poverty, unsafe water supply and poor sanitation are an opportunity for spreading Vibrio cholera. Yemen’s proximity to the horn of Africa allows about 200-300 individuals to cross to Yemen daily, mainly through Hodeidah, on the red sea. This has resulted in spread of diseases to Yemen, including cholera. We investigated a cholera outbreak in Hodeidah in August 2010. This report summarizes the results of this investigation.

Methods: We defined a case as any person from Almrawieh district who had watery diarrhea with/without vomiting during 8/06-15/2010. Five rectal swabs were collected and sent for laboratory confirmation. Collected data were analyzed using Epi Info.

Results: Vibrio cholera O1 serotype Hikojima was confirmed to be the cause of the outbreak. Index case was a refugee from Somalia who died from acute watery diarrhea. A total of 500 cases were identified, attack rate was 0.37% and case fatality rate was 1 %. Age ranged from 0.08 to 90 years, with a mean of 14.8 years. Over 50% of the cases were less than 22 years of age. The most frequent reported symptom was watery diarrhea, 82%. Providing proper case management, clean water supply and chlorinating the water resulted in halting the outbreak; 10 days after the first cases were reported.

Conclusion: Unsafe water supply and frequent crossing of individuals from the horn of Africa to Yemen contributes to spread of diseases. Rapid response for investigation and control measures contained the outbreak.

Key words: cholera, outbreak investigation, refugees.
