Hepatitis E virus infections in travellers: assessing the threat to the Australian blood supply

In developed countries hepatitis E virus (HEV) infections have occurred predominantly in travellers to countries endemic for HEV. HEV is a virus that is transmitted by blood donations. In Australia Individuals diagnosed with HEV are excluded from donating fresh blood .

The aim of this study is to describe overseas-acquired HEV cases in Australia in order to determine whether infection in travellers pose a risk to Australia blood safety.

Details of all notified HEV cases in Australia from 2002 to 2014 were accessed. 332 cases of HEV were acquired overseas. Travel to India accounted for most of these infections, although the importation rate was highest for Nepal and Bangladesh, are endemic areas for HEV and malaria.

Countries for which donations-related travel restrictions for malaria exist, accounted for 94% of overseas-acquired HEV cases. In Australia blood donations from travelers in these three countries are suspended for at least four months, so the risk of HEV transmission through blood products is minimized.

Viral metagenomics and blood safety

The characterization of the human blood-associated viral community (also called blood virome) is essential for epidemiological surveillance and to anticipate new potential threats for blood transfusion safety. Currently, the risk of blood-borne agent transmission of well-known viruses (HBV, HCV, HIV and HTLV) can be considered as under control in high-resource countries. However, other viruses unknown […]

New viral risks in blood transfusion by 2016

Viral safety remains a major concern in transfusion of blood products. Over years, the control measures applied to blood products were made more and more sophisticated; however, the number of infectious agents, and notably of viruses, that can be transmitted by transfusion is increasing continuously. The aim of this review paper is to actualize that […]
