title: Prevalence of antibodies against respiratory viruses in children of Koulikoro (Mali).
abstract: The prevalence of antibodies to viruses associated with respiratory illnesses (influenza, corona, R.S., adeno, parainfluenza Mycoplasma pneumoniae) has been investigated in 119 children under 3 years of age (Koulikoro region Mali) and 50 persons 15-19 years of age (Bamako/Mali). In the surveillance period (March 1982-September 1982) an outbreak of respiratory disease in association with RS virus took place. A rise of CF titer has been found in 90.8% of the children; 59.1% of them presented a fourfold or greater increase of titer. The GMT values rose from 1:7 to 1:48. Concerning influenza viruses a higher incidence of positive reactions has been observed only for H3N2 viruses. A fourfold CF rise of titer has been observed for adenovirus and mycoplasma pneumoniae in 3 cases each, for parainfluenza type I and III in 2 cases each, and for parainfluenza II in 1 case. In persons 15-19 years of age the incidence of positive CF reactions was relatively high (68%-98%), but the GMT values were moderate (1:12-1:25). These data confirm that the frequency of viral respiratory diseases is the same in tropical countries as in countries with a temperate climate.
