The biggest use of blood products in NZ is in cancer treatment. Around 28% of all blood donations are used by cancer patients.
There is increasing awareness of the risks associated with the transmission of mosquito borne viruses (arboviruses) via blood transfusions. While the mosquitoes that carry these viruses are not present in New Zealand, the risk of acquiring the infection is linked to being bitten while travelling overseas.
The most important viruses in this group are Chikungunya, Dengue, West Nile Virus and Zika. There is considerable overlap in the geographic risk areas for some of these viruses.
When can I donate?
Most people who travel outside New Zealand are still able to donate blood when they return. However, travel to an area where there is a risk of exposure to certain diseases can result in symptomless infection(s) that can be transmitted through blood transfusion.
