sis in daycare centers is considerably high. There had been inad-
equate report of giardiasis in Indonesia.

the number of children with symptomatic and asymptomatic giar-

Methods This descriptive study was conducted in daycare cen-
ters between August to October 2002. Giardiasis was defined as
the occurrence of G. lamblia cyst in stool specimen independent
from the presence or absence of symptoms. Four of 12 daycare
centers were chosen by cluster random sampling. All children aged
1 to 60 months attending daycare and staying for at least 2 weeks
were included in this study. Three consecutive stool specimen pre-
served by 10% formalin, concentrated by formalin ether, were ex-
amined microscopically to find the G. lamblia cyst.
Results Giardia lamblia cysts were found in 27 (29%) of the 92
children attending the daycare centers at Rancabali tea plantation
(95%CI 20;38.6%). Of these children, 15 showed symptoms such
as diarrhea episodes (8 children), diarrhea (5 children), bloating (5
children), abdominal cramp (5 children), and vomiting (3 children).
