[Epidemiological characteristics of water-borne outbreaks of typhoid in North Africa]

On the basis of analysis of several water-borne outbreaks in Northern Africa the authors came to the conclusion that when the population applies for medical aid rarely hospitalization curve reflected the morbidity curve. Attention is paid to the fact that in late and incomplete hospitalization of the patients at the period of water-borne outbreaks of typhoid fever some of the cases are subsequent and are not associated with the factor causing their primary origination. High morbidity indices in older age groups (15-39 years old persons) are due to their greater applicability for medical aid. The group of children aged from 10 to 14 years old is the one affected the most.
