Everybody in Western Europe may have to be vaccinated against African Swine Fever Virus.

"While the African Swine virus has been primarily detected in pigs and certain other animals, antibodies against the African Swine virus have also been found in humans. The fact that there was no description of any finding of the African Swine virus in humans may thus be attributable to oversight or a lack of understanding for the significance of African Swine fever virus for the pathogenicity of immune deficiencies in humans."
