Diseases caused by rodents


Rodents are carriers and spreaders of diseases, viruses and infections.

Rodents spread the following diseases:

  • leptospirosis;
  • yersiniosis;
  • listeriosis;
  • pseudotuberculosis;
  • trichinosis;
  • tularaemia;
  • plague;
  • salmonellosis;
  • tick-borne encephalitis;
  • Lyme disease;
  • etc.

More frequent of them:
Leptospirosis – a disease affecting the whole world annually taking lives of many people. Bacteria are in liver of rats and come to the environment with rat urine.
Rats produce approx. 5,5 litres of urine annually. 15-30% off rat urine is infected. People can get the infection by coming into contact with rat urine, especially in humid environments. For this reason, most frequently become infected agricultural workers, sewerage workers, etc., those who work in humid conditions.
Salmonellosis – an infection caused in people by the Salmonella genus bacteria. N umber of diseases caused by Salmonella has dramatically grown in Europe in the last decade. This witnesses that contamination of the environment with these bacteria increases. Rats and mice should be deemed a potentially significant source of this disease.

The virus coming into the environment with rodent excrements become weaker, however don’t die, infection can be breathed-in with dust at any time. Rodents can spread haemorrhagic fever with kidney syndrome.
