[Maternal syphilis and congenital syphilis in Latin America: big problem, simple solution].

From the data submitted to the Pan American Health Organization (PAHO) by nationwide programs against sexually transmitted diseases (STD), HIV infection, and AIDS (2002), one can estimate the overall prevalence of syphilis among pregnant women to be 3.1% and to range from 1.00% in Peru to 6.

Estimating HIV/AIDS prevalence in countries with low-level and concentrated epidemics: the example of Honduras.

Estimates of HIV/AIDS prevalence are important, because they are the primary measure of the current state of the epidemic in a country. How estimates of HIV/AIDS are made depends on the level of the epidemic. For estimates of HIV/AIDS prevalence in low-level and concentrated epidemics it is necessary to disaggregate the total adult population into sub-groups based on the relative risk of infection.

Status of the HIV/AIDS epidemic and methods to monitor it in the Latin America and Caribbean region.

The paper presented is a review of the available epidemiological data on the situation in the Latin America and Caribbean (LAC) region, and looks at HIV prevalence in specific population groups. At the end of 2001, HIV remains an important health issue in the LAC region. Twelve countries in the region have an estimated prevalence of 1% or higher among pregnant women.
