ABSTRACT
Cryptosporidiosis among children who attended Yangon Children's Hospital from March to October 1996 was studied. A total of 396 stool samples were collected after admission to the hospital. Simultaneously, a set of questions was filled to ascertain the duration and motion of diarrhoea of children. Stool characteristics were also recorded. Cryptosporidium oocysts were detected by staining with Kinyoun's acid modified method by Haley and Standard 1973. Random samples of 238 male and 158 female children of ages ranging from one month to ten years old were included in this study. It was found that the duration of diarrhoea ranged from one to 150 days. Number of motions also ranged from one to 40 times per day. Diarrhoea with either blood or mucous (dysentery) was found in 61 cases (15.4 per cent). cryptosporidium oocysts were found in 5 cases (1.3 per cent) of children; three were from watery diarrhoea cases and two from dysentery cases. From the cases detected, the age range was from 10 months to five years and the duration of illness was from 3 to 30 days. Four cases were with moderate degree of dehydration and one case was associated with HIV infection.
