Somewhere in America right now, a rat is sizing up its next victim. It sounds like the tagline for a horror movie, but the reality is grimly mundane: between 14,000 and 24,000 Americans are bitten by rats every single year.

That's roughly one bite every 20 minutes, around the clock, 365 days a year.

Who's Getting Bitten?

Rat bites don't happen randomly. The victims follow a troubling pattern:

Infants and young children account for the majority of serious bites, often attacked while sleeping
Low-income urban residents face dramatically higher risks due to deteriorating housing
The elderly and disabled who may have difficulty escaping or defending themselves

Cities like New York, Chicago, and Los Angeles report the highest numbers, but rat bites occur in all 50 states. One Philadelphia study found that rat bite rates in impoverished neighborhoods were ten times higher than in affluent areas.

Why Rats Attack

Rats aren't naturally aggressive toward humans. Most bites happen for predictable reasons: a sleeping person unknowingly rolls onto a rat, food residue on skin attracts a hungry rodent, or a cornered rat defends itself.

But here's where it gets unsettling. Rats have learned that humans—particularly vulnerable ones—aren't always a threat. In severe infestations, rats grow bold. They'll climb into cribs. They'll gnaw on the fingers and toes of sleeping residents.

In one documented case from 2017, a Baltimore infant suffered over 100 rat bites in a single night.

The Health Risks

A rat bite isn't just painful—it's potentially dangerous. Rats carry over 35 diseases transmissible to humans, and their bites can deliver:

Rat-bite fever – A bacterial infection that's fatal in 10% of untreated cases
Tetanus – If the victim isn't vaccinated
Secondary infections – Rat mouths harbor countless bacteria

The psychological toll is harder to measure. Imagine trying to sleep knowing rats have already bitten you once.

A Problem That's Getting Worse

Urban rat populations are exploding. Climate change means milder winters and longer breeding seasons. The COVID-19 pandemic, which shuttered restaurants and disrupted garbage collection, triggered what exterminators called a "rat apocalypse" in major cities.

New York's rat population alone is estimated at 2 million or more—roughly one rat for every four residents.

The solutions aren't simple. Rats are intelligent, adaptable, and reproduce at staggering rates. A single pair can theoretically produce 15,000 descendants in one year. Cities spend millions on pest control with mixed results.

What Can Be Done?

Experts say prevention remains the best defense. Sealing entry points, eliminating food sources, and maintaining clean living spaces all help. But for residents in neglected housing with absent landlords, these steps may be impossible.

The rat bite statistics tell a story that goes beyond public health. They reveal deep inequalities in housing, sanitation, and basic human dignity. Until those underlying issues are addressed, thousands of Americans will continue waking up with teeth marks as evidence of their unwanted nighttime visitors.
