Now Europeans are also contracting the disease here, say scientists today (Monday 3 September 2007) at the Society for General Microbiology’s 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 September 2007.
Hepatitis E virus is one of the few viruses which has been shown to be transmitted directly from animals through food. It was recently thought to be confined to developing countries, and although scientists are still unsure exactly how it spreads to people, direct contact with pigs or eating contaminated pork products is a likely route.
“If this proves to be a relevant route for pig to human infection for Hepatitis E in Europe, food safety regulations might need to be adapted accordingly”, says Dutch researcher Erwin Duizer. “Where we do find Hepatitis E virus identified in Europe then the strain is usually closely related to the viruses found in pigs in the same country”.
Far fewer cases of Hepatitis E virus are reported than actually occur, since doctors currently rarely ask for the relevant diagnostic tests in many industrialized countries. Although they do not yet know the exact route for most infections, the scientists do know that these viruses can infect people if they eat infected pig’s livers without cooking them.
Genetic material from Hepatitis E viruses has already been detected in pig livers being offered for sale in Japan, USA and the Netherlands, proving that European pigs are in contact with Hepatitis E. Wild boar products could present a similar risk.
“To improve understanding of this disease, doctors should routinely start asking for Hepatitis E screening tests, even if the patient has not been travelling in India, China or other countries where they might expect to be at risk of infection” says Erwin Duizer. “Once more people are correctly diagnosed with viral Hepatitis E, they can be treated more effectively and we can learn more on the transmission routes. Current rates of diagnosis are up to13% of acute viral hepatitis patients in European countries, but we think the true rate is much higher. Up to 3% of blood donors in Europe show evidence of exposure to the virus through detectable antibodies”.
“We also need to quickly work out the local route of infection in Europeans, as knowing if Hepatitis E is directly caused by eating pork meat or liver, or caused by foods or people being in contact with pig faeces, will make it possible to implement effective preventive measures”, says Erwin Duizer.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
