ABSTRACT
Due to limited laboratory facilities in the tropics, the exact role of enteric viruses in causing diarrhea among adults in the tropics is unknown. The purpose of this report is to describe a multicenter study undertaken in Djibouti to determine the prevalence of a large panel of enteric viruses using immunochromatography; antigenic detection by ELISA, RT-PCR cellular inoculation, sequence analysis; and indirect serology. Study samples were collected from 108 patients presenting acute and sporadic diarrhea. Although they are well known causes of diarrhea in children, rotavirus and adenovirus were identified in only 2 and 5% of adults respectively. In contrast human caliciviruses (HuCVs) and enterovirus were identified in 25 and 42% of adult cases respectively. Uncommon genotypes of HuCVs and recombinant forms (junction pol/l cap) as well as a significant number of sapovirus (30%) were identified. Further study is needed to clarify the role of enterovirus (echovirus) in the etiology of acute diarrhea in adults. No polivirus was identified. These new data from the Horn of Africa increase our knowledge about the epidemiology of acute infectious diarrhea that is a major public health problem and potential danger for travelers.
