[Risk of nosocomial infection in Intertropical Africa. Part 4: prevention].

: Nosocomial infections have long been neglected in Sub-Saharan Africa, even though their prevalence is higher than in developed countries. Recently, however, this major public health problem has been the focus of a growing number of recommendations not only from the World Health Organization but also from some national health ministries. Because of the numerous limitations especially in financial resources in these regions, priority must be given to the implementation of simple and cost-effective measures. Accordingly the greatest efforts must be devoted to educating healthcare workers and patients about the importance of handwashing, eliminating unnecessary injections and transfusions, performing the latter acts in aseptic conditions, isolating patients with communicable diseases, handling waste products safely, and using antimicrobials properly. Amid the daunting health issues facing Sub-Saharan Africa, implementing these inexpensive measures that could save the lives of thousands of patients and healthcare workers appears easy. However it will require a cultural revolution. The keys to success will be changing the organizational culture, developing a commitment to prevention and evaluating performance regularly.
