    Author: Siddique AK.
    Journal: Glimpse; 1994; 16(5):3-4. PubMed ID: 12288419.
    Abstract:
    In July 1994, one of the worst cholera epidemics broke out among the nearly a million Rwandan refugees in Goma, eastern Zaire. The United Nations High Commission for Refugees estimated that nearly 12,000 people died during the epidemic. The International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) sent an eight-member medical team to Goma headed by Dr AK Siddique, a senior scientist of the Center and head of the Epidemic Control Preparedness Program, Dacca, Bangladesh. During their two-week stay, the team, in collaboration with UNICEF and the Ministry of Health, Zaire, conducted epidemiological assessment, operated a temporary treatment center and provided technical advice on case management of cholera and shigellosis to other health workers. The team also set up a microbiology laboratory in Goma to identify the pathogens responsible for the epidemic and their drug sensitivity patterns. The team visited a number of temporary treatment facilities in two of the five camp sites and provided technical advice to the health-care providers. They also visited treatment facilities in Goma city, where an estimated 200,000 refugees were affected by the epidemic. Deaths from cholera even in the treatment centers were much higher than expected. The overall case-fatality rate in the treatment centers was nearly 15%. Laboratory investigations showed that the initial epidemic was indeed caused by Vibrio cholerae strains resistant to tetracycline and doxycycline. By the first week of August, the number of cholera cases was declining, but the number of dysentery cases was increasing rapidly. Predominantly Shigella dysenteriae type 1 was responsible, which was resistant to most drugs used for treating shigellosis, except mecillinam. Inappropriate rehydration therapy and inadequate experience of health workers failed to prevent deaths. The team took over the operation of temporary treatment center at Katindo in Goma city with one of the highest case-fatality rates (14.5%) and could reduce the fatality rate to less than 1%.
