The purpose of this study is to estimate the number of cases of rheumatic heart disease, pyoderma, and scabies in school age children in Fiji. In addition the study will describe the features of rheumatic heart disease, pyoderma, and scabies in these children. Study participants will include 5200 primary school children, ages 5-14, from 21 primary schools in the Central Division of Fiji. These children will be examined for pyoderma, scabies, and the doctor will listen to their heart with a stethoscope. Any child that has a heart murmur detected will have their heart looked at through an echocardiogram test (uses sound waves to create a picture of how the heart is working). Any child that is found to have rheumatic heart disease will be referred to a pediatric cardiologist for further evaluation. Participants will be involved in the study for about 2 days.
