In the Netherlands zoonoses are of major importance because it is a densely populated country with high numbers of livestock and pet animals and human activities favours close contact with wildlife such as migrating waterfowl, deer and fox populations. Recent zoonotic outbreaks of importance are avian influenza in poultry in 2003 and Q fever epidemic in 2007-2010. Besides the threat for outbreaks, endemic zoonoses still need attention.
Zoonotic diseases affect and are carried by domestic animals, farm animals, wild animals or rodents such as mice and rats. Humans are frequently exposed to zoonotic organisms since they can also spread into the environment, such as children's sandpits, water and food. Some diseases are transmitted by insect or tick bites. The insect or tick is then termed a ‘vector’ (from the Latin word for carrier).
One Health approach
RIVM coordinates national activities on the signalling and response of zoonoses together with key partners in the veterinary field. Monthly meetings are being organised to discuss the zoonotic signals between veterinary and (regional) public health partners. Strategic focus of research activities in the field of zoonoses are livestock-, wildlife- and vector borne zoonoses on the animal-human interface. RIVM has unique expertise in the field of parasitic zoonoses and advices national authorities.
Examples of research activities include Livestock Farming and Neighbouring Residents’ Health, Lyme disease and other tick-borne diseases, Q fever, parasitic zoonoses in wildlife and livestock and rodent borne diseases.
Zoonoses are important to signal and control in international context. RIVM collaborates in many international activities, coordinates international projects related to zoonoses and advices international bodies such as European Food Safety Authorithy (EFSA), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO)and Food and Agriculture Organization of the United Nations (FAO) related topics on zoonoses.
Zoonotic diseases are infectious diseases spread between animals and humans. RIVM short film on Zoonoses describes how people can get zoonotic diseases and RIVM role in the control of communicable infectious diseases.

VOICE-OVER: Animals may carry bacteria, viruses and parasites.
Some of these micro-organisms can be transferred from animals to people
and may cause diseases. Such diseases are called zoonoses.
People can come into contact with pathogens from animals in different ways.
or the environment.
They can also be transmitted through little creatures,
such as ticks and mosquitoes,
that can transfer diseases from an animal to a human.
These are known as vectors.
Proper hygiene can often prevent people from catching a zoonosis.
Make sure you prepare meat and other raw products in a suitable manner.
Always wash your hands after direct contact with animals.
And check yourself for ticks when you have been in the countryside.
