    VIRAL and Chlamydial Etiology of Acute Respiratory Infection in Infants in Addis Ababa
    (Addis Ababa University, 1993-06) Enaro Desalegn; Petros Beyene (PhD)
    A case - control study was calTied out to establish the etiologic agents causing acute respiratory infections in infants in Addis Ababa using the immunofluorescence technique. Special attention was given to viruses and Chlamydia trachomatis. The influence of the level of education, passive smoking, breast feeding, and meteorological factors in association with viral infection in acute respiratory infections was investigated using the questionnaire data. Nasopharyngeal aspirates of 225 cases and 178 control infants were studied for the presence of respiratory syncytial virus, parainfluenza virus, influenza virus types A and B, adenovirus and Chlamydia trachomatis between January, 1992 and December, 1992. The overall viral and chlamydial detection rate was 48.9%. The total viral detection rate was 32.9%, out of which respiratory syncytial virus accounted for 31.1 %. Chlamydia trachomatis was detected in 16%. In control infants 2.8% of viral detection was observed. Five control infants had detectable viral antigens but no control infants had detectable Chlamydia trachoma tis antigens. Infants having acute respiratory infection showed significantly higher rates of viral detection than healthy control infants (Chi-Square Yates cOlTected = 52.64, p
