Yellow fever in Argentina and Paraguay

Yellow fever has returned to Argentina and Paraguay for the first time since 1967 and 1974, respectively. In January 2008, an outbreak of jungle yellow fever occurred in Paraguay. This was followed by a number of confirmed cases near the capital Asunción, the first urban cases in South America since 1942. In March, Argentina reported confirmed human cases of jungle yellow fever. Mass vaccination campaigns are under way in both countries. PAHO/AMRO and WHO have been supporting national response efforts and the vaccination campaign. In particular, through the ICG (International Coordinating Group) mechanism, 2,000,000 doses of yellow fever vaccine were shipped to Paraguay. WHO has also updated International travel and health advice for visitors to these countries (please see).
