We apply the technique of Expectation Maximization (EM) to estimate the HIV prevalence in the three countries in North America namely, U.S.A., Canada and Mexico. We conclude that if we can estimate the recent HIV incidence in a country, then HIV prevalence can be rather accurately estimated. Our results lead us to think that while the official estimates for Canada and Mexico may be fairly accurate, those for the United States are rather uncertain.
