Meeting of the Advisory Committe on Medical Research, 12. Pan American Health Organization; 25-29 Jun. 1973

Recuperación de virus amarílico, procedente de un mono centinela, en las cercanias de Belem, Brasil / Recovery of yellow fever virus from a sentinel monkey near Belem, Brasil

Yellow fever virus was isolated from a sentinel Cebus monkey on 4 December 1964 in the Utinga Forest near Belem, Brazil. Ten of 30 wild monkeys had yellow fever antibody. Over 1,200 samples from other vertebrates were tested without evidence of involvement with yellow fever virus. No human cases were found. The episode would have gone undetected if routine surveillance for arboviruses had not been in progress
