Since 2010, PAHO/WHO has collaborated with the countries of Latin America and the Caribbean (LAC) to implement a regional initiative for the elimination of mother-to-child transmission of HIV/AIDS and congenital syphilis. In 2013, 2324 children were born with HIV in LAC which is a decrease of 45% than in 2010. In Cuba, less than 2% of children whose mothers have HIV are born with the virus, the lowest rate possible with prevention methods available today. As a result, Cuba recently received formal validation from PAHO/WHO that it has eliminated mother-to-child transmission of HIV. Now other parts of the Caribbean have achieved similar success in eliminating congenital sexual transmitted diseases (STDs).
