Hantavirus infections are diseases caused by hantaviruses (officially orthohantaviruses). There are different types of hantaviruses. Mice and rats in particular can carry these viruses. They can transmit the virus to humans. In the Netherlands, this is very rare.

Marburg virus disease is an infectious disease that can make people very ill, possibly leading to death. Like Ebola, the Marburg virus is a cause of viral haemorrhagic fever. People with the disease often have internal bleeding. The Marburg virus is rare and occurs in Africa. 

SARS-CoV-2 is the coronavirus that causes the disease COVID-19. The symptoms often resemble the common cold at first. Some people do not become ill at all, or are only mildly ill from the virus. Others may become seriously ill and sometimes even die from the disease. Some people keep having symptoms for a long time after having COVID-19. If their symptoms persist for longer than 3 months, it is called post-COVID.

Ebola is a rare but serious infectious disease that can cause bleeding in the body. The official name is Ebola virus disease, formerly known as Ebola haemorrhagic fever. It is caused by the Ebola virus. So far, Ebola has only occurred in parts of Africa.

Zoonoses are infections  that are naturally transmissible directly or indirectly between animals and humans. Domestic animals, farm animals, wild animals or rodents such as mice and rats, who may or may not be affected themselves, carry zoonotic diseases.
