Vampire bat rabies: ecology, epidemiology and control

Area of Science:

• Veterinary Medicine
• Infectious Diseases
• Mammalogy

Background:

• Bats host numerous viruses, with a long-standing association between rabies virus and vampire bats.
• Vampire bats, endemic to Latin America, possess unique blood-feeding (hematophagy) adaptations evolved in the New World.
• These adaptations enhance rabies virus transmission, posing a significant public health and agricultural concern.

Purpose of the Study:

• To review the ecological factors making vampire bats effective rabies vectors.
• To assess the current status of rabies transmitted by vampire bats.
• To explore future prospects for the spread and control of this zoonotic disease.

Main Methods:

• Literature review focusing on vampire bat ecology and rabies epidemiology.
• Analysis of factors influencing vampire bat population dynamics and virus transmission.
• Synthesis of current data on rabies prevalence and control measures.

Main Results:

• Vampire bat adaptations for hematophagy facilitate efficient rabies virus transmission.
• Increased vampire bat populations, linked to Old World livestock and landscape changes, have amplified rabies re-emergence.
• Rabies transmitted by vampire bats poses a growing threat to livestock and human populations in Latin America.

Conclusions:

• The unique ecology of vampire bats establishes them as critical vectors for rabies.
• Effective control strategies are crucial to mitigate the increasing risk of vampire-transmitted rabies.
• Understanding transmission dynamics is key to preventing future outbreaks.
