RESUMO
Climatic alterations arising in the north of Perú as a result of the El Niño phenomenon (ENSO) have caused variations in the crop volume, changes in the direction of rivers and probably an increase in the rodent population. In February 1999, in a native community in Jacocha, Huancabamba, Piura's mountains, Perú, an outbreak of bubonic plague appeared with five human cases, one of which lead to death. The diagnosis was confirmed by serology (passive hemaglutination). The presence of antibodies in dogs of localities close to Jacocha has confirmed the circulation of Yersinia pestis in the region. The outbreak was controlled by the local sanitary authorities' prompt action. This episode, after an epidemiological silence for more than four years, showed the necessity of intensifying the plague epidemiological surveillance system in this area.

As alterações climáticas produzidas no norte do Perú devidas ao Fenômeno El Niño (ENSO), ocasionaram variações no volume das safras, redistribuição do curso dos rios e provavelmente aumento da população de roedores. Em fevereiro de 1999, em uma comunidade indígena em Jacocha, Huancabamba, na serra de Piura, Perú, surgiu um surto de peste com cinco casos humanos, um dos quais faleceu. O diagnóstico foi confirmado pela sorologia (hemaglutinação passiva). A presença de anticorpos em cães de localidades próximas de Jacocha confirmaram a circulação da Yersinia pestis na área. O surto foi debelado pela rápida atuação das autoridades sanitárias locais. O episódio após silêncio epidemiológico por mais de quatro anos, mostrou a necessidade de reforçar o sistema de vigilância epidemiológica de peste nesta área.
