*The number of persons examined/screened.
1Definite cases: papillomatous or ulceropapillomatous.
2Suspected cases: scanty macules and maculopapulomatous.
3Rates of disease are calculated per 1,000 populations by dividing the number of cases of disease reported by the population in each age group and multiplying by 1,000.
