Objective To present the steps followed for the diagnosis and control of an outbreak of nosocomial infection at a neonatology service. Methods Descriptive study of an outbreak occurred at the neonatology service of "Vladimir Ilich Lenin" hospital in Holguín province during October and November. The universe of study was 27 newborns who were hospitalized during the length of time of this study; 15 of them were diagnosed as generalized nosocomial sepsis patients. For the study, diagnosis and confirmation of the outbreak, the steps set by the National Program of Prevention and Control of Nosocomial Infections of the Cuban Ministry of Health were followed. Results The outbreak had multifactoral cause. It was confirmed that infection in 11 newborns was caused by Serratia mascescens germ. Three of them died. The rate of acquired generalized sepsis in the epidemic period was 33.3 per 100 admittances, much higher than that of the endemic period six months before, which amounted to 5.6 per 100 admittances. Girls prevailed and the average age was 2-7 days. Conclusions It was proved that the National Program of Prevention and Control is very useful and effective as a working tool in the hospitals and, particularly in the neonatology services where there are high risk of occurrence of outbreak of nosocomial infection causing high infant morbidity and mortality.
