Travelled to or lived in areas where mosquito-borne infections are endemic, if you visited malaria endemic areas within 3 months or resided in malarial endemic areas within 3 years, or, if you visited West Nile Virus endemic areas (North America or WMV endemic countries in Europe) within 4 weeks before the date of blood donation.
