Executive Summary
vampire bat

Although the efforts of the countries of the Americas have produced excellent results in controlling human rabies transmitted by dogs—bringing about a reduction in approximately 95% of all human cases thus originated—cases due to vampire bats have increased considerably. In 2004, for the first time in the history of the Regional Program for Rabies Elimination coordinated the Pan American Health Organization (PAHO), the number of human rabies cases transmitted by wildlife was greater than the number transmitted by dogs (Schneider, 2005). In 2005, this trend became clearly manifest when 51 cases of bat-transmitted human rabies were reported, in contrast to 11 dog-transmitted human rabies cases (Regional Information System for the Epidemiological Surveillance of Rabies in the Americas [SIRVERA/PAHO], 2006). Most of the cases transmitted by vampire bats occurred in the Amazon region, which includes territories from the eight countries participating in the Amazon Cooperation Treaty Organization (ACTO).

With the goal of discussing the topic of rabies transmitted by vampire bats in the Amazon Region, PAHO, ACTO, the Inter-American Institute for Cooperation on Agriculture (IICA), the Ministry of Health (MS) of Brazil and the Ministry of Agriculture, Livestock and Supply (MAPA) of Brazil held the Expert Consultation on Rabies Transmitted by Vampire Bats in the Amazon Region, on 10–11 October 2006, at the PAHO Country Office in Brasilia, Brazil.

The objectives of the Consultation were as follows:

  • Review the experiences to date in this territory and generate recommendations to support the countries in the Amazon region that are at risk of outbreaks or cases of human rabies transmitted by vampire bats.
  • Stimulate interinstitutional collaboration for the prevention and control of outbreaks of this disease.
  • Establish partnerships for technical cooperation among the Amazon countries.

A total of 76 participants attended the meeting, including professionals from the health sector who represented seven of the countries and technical personnel from the agricultural sector of agriculture from four the countries. Others were national and international experts in matters related to the topic of the meeting—for example, the Centers for Disease Control and Prevention (CDC) of the United States—and representatives of state and municipal governmentes where cases of human rabies transmitted by vampire bats have been reported. In addition to staff members from the international organizations in charge of the meeting, delegates were present from the World Organization for Animal Health (OIE), the Oswaldo Cruz Foundation (FIOCRUZ / Ministry of Health, Brazil), and such nongovernmental organizations (NGOs) as the World Society for the Protection of Animals (WSPA) and the Latin American Association for Wildlife Conservation and Management, as well as members of the National Council of Municipal Health Secretariats (CONASEMS) of Brazil.

The program was planned so that it allowed for expeditious interaction among international researchers and experts and authorities responsible for controlling local outbreaks, as well as the full involvement of representatives of national and international, governmental and nongovernmental organizations. The agenda included expert presentations and panels followed by discussion and working groups who reviewed the selected subjects and prepared recommendations subject to general discussion.

As a result, the following recommendations were approved and submitted in the plenary sessions:

  • Strategies should be adopted so that people attacked by bats receive post-exposure treatment in accordance with WHO technical standards. In remote areas with difficult access to health services, where many of the assaults on people are registered, pre-exposure treatment is recommended.
  • Research should be promoted on regimens to facilitate the logisitics of applying the rabies prophylaxis.
  • Local activities should be promoted in the areas of health education and control of bat populations, in an attempt to have both the projects and the activities respect local cultures and involve local communities and their leaders.
  • Commissions should be created at the central and local levels that are part of the health, agricultural, educational, and environmental sectors, so that they might formulate broad and coordinated local strategies in which the functions and responsibilities of each participant are clearly indicated.
  • The countries of the Amazon region should prepare agreements and projects on this subject, given the importance both for public health and for the economy of human rabies transmitted by vampire bats.
  • Rabies programs and rabies control measures should be strengthened at all levels. PAHO/WHO is asked to act as advocate for this issue with the ministries of health and agriculture, in an effort to point out the urgency of taking action against human rabies transmitted by vampire bats.
DVD: Rabies in Vampire Bats Bibliographical CD on Bat Rabies

During the sessions, participants viewed a video (DVD) on rabies transmitted by vampire bats, entitled Rabies and Vampire Bats, which was produced by PAHO and the Government of Mexico, with support from the Governments of Brazil and Peru. In addition, technical personnel involved in the prevention and control of bat-transmitted rabies were given a CD-ROM with a bibliography on the subject of the consultation.
