Two threats: (1) physical attacks — 4.5M bites per year in US alone, ~70 fatalities; (2) rabies via bite — almost 100% fatal once symptoms appear. Vaccine works only before symptoms.

Worldwide. Highest rabies burden in India, Africa, Southeast Asia. US, Canada, Mexico, Western Europe, Australia: dog rabies eliminated.

Stray and unvaccinated dogs are the main reservoir. Children most vulnerable due to height and inability to defend themselves.

Distinctive black mosquito with white lyre-shaped markings on thorax. Primary vector of dengue, yellow fever, Zika, chikungunya in tropical Asia.
