Swine influenza is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. Influenza viruses that commonly circulate in swine are called “swine influenza viruses” or “swine flu viruses.” Like human influenza viruses, there are different subtypes and strains of swine influenza viruses.
Hepatitis A is an acute infectious disease of the liver caused by the hepatitis A virus, a small, non-enveloped hepatotropic virus classified in the genus Hepatovirus within the family Picornaviridae.
Hepatitis B is a liver disease that results from infection with the hepatitis B virus (HBV) and is spread through contact with infected body fluids or blood products. Following acute infection with HBV, some people go on to develop a chronic infection.
Hepatitis E is an acute or chronic infection with the hepatitis E virus (HEV). In Europe, most of the infections are locally-acquired and asymptomatic.
Legionnaires’ disease is a multisystem disease which causes pneumonia due to gram-negative bacteria (Legionella spp.) found in freshwater environments around the world. Humans are infected by inhalation of aerosols containing Legionella.
Norovirus cause gastrointestinal illness to humans. Norovirus infection can cause vomiting, diarrhoea, and stomach pain. Less common symptoms are low fever, chills and headache.
Variant Creutzfeldt-Jakob disease (vCJD) is a relatively new and rare neurological disease, classified as a Transmissible Spongiform Encephalopathy (TSE).
