Severe ulcerative herpes of mouth and eye following measles

Abstract

Malnourished children in the north of Nigeria who had had a severe attack of measles were prone to deep ulcers of the mouth and eyes. Herpes simplex virus was isolated from 17 of 25 of the mouth ulcers which were erosive, slow to heal and caused much suffering and loss of weight. Herpes virus was also identified, either by immunofluorescent staining or viral culture, in the corneal scrapings of the eye ulcers from 16 of 34 children. These ulcers healed slowly in two to six weeks leaving damaging scars which impaired vision and caused blindness in some cases. It is suggested that measles leads to profound depression of cell mediated immunity in malnourished children with the consequence that secondary herpes simplex infections become abnormally severe and erosive.
