Nuevos casos de infección humana por Diphyllobothrium pacificum (Nybelin, 1931) Margolis, 1956 en Chile y su probable relación con el fenómeno de El Ni o, 1975-2000 New cases of Diphyllobothrium pacificum (Nybelin, 1931) Margolis, 1956 human infection in North of Chile, probably related with El Ni o phenomenon, 1975-2000

The effect of El Ni o/ENSO on terrestrial atmosphere appears to be extremelly clear. However there are outstanding evidences showing its effect on humans and their activities. In fact, prevalence of some parasitic infections have increased during El Ni o phenomenon. The reasons for that are the migrations of sylvatic mammals, fishes and birds as well as by environmental contamination. In this report, we show evidence respect of new cases of human infection by Diphyllobothrium pacificum clearly associated with a cyclic manifestation of El Ni o in the Chilean Pacific coast during 1975-2000
