Rabies is the deadliest infection we know how to stop. Once symptoms begin it kills almost everyone. Before then, soap, water and a course of vaccine almost always save the person.
100%
Fatality once clinical symptoms appear · WHO, 2026
Yet an estimated 59,000 people still die of dog-transmitted rabies every year. Most of them are in rural Asia and Africa, and most never reached a vaccine in time.
99%
of human cases come from dog bites or scratches
40%
of deaths are children under 15
01 · The clock
A window measured in weeks, then a wall
The virus creeps along nerves toward the brain. Anywhere along that path, vaccine works. Once it arrives and symptoms begin, it is too late.

03 · The proof it can end
The Americas cut dog-rabies deaths by 98%
From 1983, mass dog vaccination across Latin America drove human cases from about 300 a year to a handful.

04 · Where the money goes
$8.6 billion a year, and just 1.5% spent on dogs
Modeled annual economic burden of canine rabies, by component. The cheapest lever, vaccinating dogs, gets the smallest slice.
Hampson et al., PLOS NTD 2015: US$8.6B/yr (95% CI 2.9–21.5B). Components shown sum to 98%. WHO recommends vaccinating ≥70% of dogs to stop outbreaks.
05 · The price of a bite
A vaccine that works but costs weeks of wages
More than 29 million people get rabies vaccine each year. For the families most at risk, one course can cost more than a month's income.

Days-of-wages range is calculated from WHO's $108 and $1–2/day figures. It is arithmetic, not a measured value.
What you can do · why it matters
The cure is a bar of soap and a phone call
Wash every bite for 15 minutesScrub with soap and running water straight away. WHO says this step alone sharply cuts the risk.
Get seen the same dayPost-exposure vaccine works at any point before symptoms start. Don't wait to see whether the animal gets sick.
Vaccinate your dogWhen at least 70% of dogs are vaccinated, transmission collapses. That is how Mexico, Chile and Bhutan got to zero.
Travelers: ask about pre-exposure shotsThis matters most for long rural stays in Asia or Africa, far from clinics.
