The WHO (World Health Organisation) has new rules for avoiding offensive names for new diseases.
(The new guidelines are aimed at removing the stigma that can be inflicted by diseases that use the names of people, places, and animals.
Under the new guidelines, Marburg disease (named after a city in Germany) might have been called filovirus-associated haemorrhagic fever, while Ebola (named after a river) might have been filovirus-associated haemorrhagic fever.)
