Question to the Department of Health and Social Care:

To ask His Majesty's Government, following reports that tropical viruses such as West Nile Virus have spread to Europe, what assessment they have made, if any, of the case for screening blood donations for tropical viruses.

United Kingdom blood services test blood donations for West Nile virus (WNV), if it is indicated by the information provided in the individual’s donor safety questionnaire that they have travelled to an area where WNV is circulating. Other tests for malaria, cytomegalovirus, and the parasite trypanosoma cruzi may be conducted if the donor has a history of recent travel to an area where one or more of these conditions is common.

The Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) advises the Government on the most appropriate ways to ensure the safety of blood, including screening. The SaBTO Virology Subcommittee is conducting a review into the approach of screening for WNV. A report with their recommendations will be published following completion of the review.
