          Abstract

          Outbreaks of attacks upon human beings by vampire bats seems to be a common phenomenon in several regions of Latin America, but the occurrence of rabies infection among humans bled by vampires, is relatively low. In the present study, two outbreaks of human rabies transmitted by common vampire bats (Desmodus rotundus) are described from Bahia State, Northeasthern Brazil, in 1991 and 1992. The first was recorded in Aporá where 308 people were bled by vampire bats and three of these die from this zoonosis. The 2nd outbreak occurred in Conde where only five people were bled by vampires, and two deaths by rabies were registered. Our data suggest that rabies transmitted by bats basically depends on the presence of virus in the vampire bat population and not on the number of humans bled by them.

          Surtos de ataques de morcegos hematófagos em seres humanos parecem ser um fenômeno comum em muitas regiões da América Latina, porém, a ocorrência de raiva humana transmitida por morcegos é baixa. No presente estudo, são descritos dois surtos de raiva em seres humanos transmitida pelo vampiro comum (Desmodus rotundus) no Estado da Bahia, nordeste do Brasil, em 1991 e 1992. O primeiro foi registrado em Aporá onde 308 pessoas foram sangradas pelos morcegos e três delas morreram por causa dessa zoonose. O segundo surto ocorreu em Conde, onde apenas cinco pessoas haviam sido atacadas pelos morcegos e duas mortes por raiva foram registradas. Nossos dados sugerem que a raiva transmitida pelos morcegos depende basicamente da presença do vírus na população de morcegos hematófagos e não do número de pessoas agredidas pelos mesmos.

              Outbreak of vampire bat biting in a Venezuelan village

              An outbreak of 154 cases of vampire bat biting in a four-month period in the gold mine of Payapal, a Venezuelan village, is reported. All patients were bitten during the night and the most bites were on their toes. No complication attributed to the bite was reported. Diagnoses of rabies virus made by means of immunofluorescence were negative. A possible reason for this outbreak may been the development of mining areas, with the inhabitants providing an alternative food source for the bats.
