Measles in Latin America: Current Situation

Extract
The Region of the Americas (North, Central, and South America and the Caribbean) successfully interrupted endemic measles transmission in 2002, but recent outbreaks in Latin America threaten to reverse this impressive achievement. Before widespread measles immunization in Latin America, measles was a common illness in early childhood and was associated with substantial mortality. During the 1960s, 600 000 measles cases were reported annually in the Region of the Americas [1]. Although measles vaccine was introduced during the 1960s, it was the creation of the World Health Organization (WHO) Expanded Program on Immunization in 1977 that marked the beginning of sustained decreases in case numbers. During 1970–1979, Latin American countries reported 220 000 measles cases annually, with incidence rates of 47–116 cases/100 000 population [2]. The highest mortality rates occurred among young children; from 1971 through 1980, measles associated mortality was 14–55 measles-associated deaths per 100 000 infants and 8–54 deaths/100 000 children aged 1–4 years. By 1980, most countries in the region had established national immunization programs; however, the mean infant measles vaccine coverage in the region was only 42%. In 2002, after more than 30 years of successful strategies and joint efforts of many countries in the region, interruption of endemic measles transmission in the Americas was achieved [3]. However, isolated cases continue to occur, due to the importation of measles from other areas of the world, sometimes causing short chains of transmissions over a few months…
