WEST NILE VIRUS
If you visit Canada, the USA, Italy, Israel, Turkey, mainland Greece, Romania, Albania or the Former Yugoslav Republic of Macedonia between 1 April and 30 November you will not be able to give blood for 28 days after your return to the UK. This is to reduce the risk of transmitting West Nile Virus to patients who need blood transfusions. West Nile Virus is an infection that can be transmitted to humans by the bites of certain species of mosquito. The Welsh Blood Service does not test blood donations for this virus.
There are some regions of Russia north of the Black Sea and the Caspian Sea which are also affected. Please contact us on 0800 25 22 66 for further details.
A position statement on West Nile Virus (WNV) is available in the Document Library of www.transfusionsguidelines.org
