[Resurgence of measles in the province of Cordoba, Argentina, in 2000].
Since 1993, ministers of health of countries of America established as a goal the eradication of measles by the year 2000. As a consequence of measles eradication vaccination strategy there has been a reduction in the incidence of reported cases. Despite that, measles has continued occurring in epidemic outbreaks in many Argentinian provinces. This paper describes and analyzes the outbreak which occurred at Córdoba province, in 2000. Out of 46 serum samples analyzed from suspected cases, 6 (13.3%) were confirmed as measles by indirect immunofluorescence and enzyme immunoassays. All of them were detected in Cordoba city among both without vaccination data and unvaccinated individuals. The epidemiological links among the measles cases could be established although the geographic source of measles importation as well as the primary infection source remain unknown. The highest measles incidence was observed in the group > or = 20 year old (50%), followed by the pre-school age group (< or = 4 year old, 33.3%). The active vaccination data directed against the suspected case contacts along with a high measles population immunity probably contributed to restrict the 2000 outbreak.
