*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.
