Hantavirus
How you get hantavirus
Hantavirus is usually spread by breathing in or touching the poo, pee or saliva of infected rats, mice or voles. It's rare in the UK.
You’re more likely to get hantavirus if:
- you live or work close to rat or mouse poo and pee
- you handle rats, mice or voles
- you’ve been bitten by a rat, mouse or vole
It can sometimes spread from person to person, but this is rare.
The risk from the type of hantavirus that has recently affected people on the Dutch cruise ship is very low.
