Respiratory syncytial virus infections in malnourished children

The prevalence of respiratory syncytial virus (RSV) infection among severely malnourished children was studied at the University of Benin Teaching Hospital, Benin City, Nigeria at a time when the infection was known to be prevalent in the community. Nasopharyngeal washings were obtained from subjects on admission and thereafter every 4 days until discharge. RSV was detected by ELISA technique. Of 20 well nourished children who served as controls, 11 were ELISA-positive for RSV (55%). Eight (16%) of the 51 patients who were malnourished were ELISA-positive, four of whom (8%) had nosocomial infection. Fever and rhinitis were the most common presenting features in the RSV-infected malnourished children. None of the children showed any clinical or radiological signs of lower respiratory tract infection. Malnourished children appear not to be at increased risk of RSV infection, and those who contract the infection usually do not manifest severe disease.
