Malaria and Tropical Arbovirus

Malaria and Tropical Arboviruses infections (which include Chikungunya, Dengue and Zika), are mosquito-borne infections which may be transmitted by blood transfusion.


When can I donate?

  • If you have remained well after leaving this country you must wait 4 months after you leave this country before you give blood
  • If you were unwell during your stay in the country or within 4 weeks of leaving the country experienced symptoms such as high fever, headache, joint pain, body pain, conjunctivitis and/or rash, you must wait 4 months after leaving the country or complete recovery (whichever is the later) before you give blood.
  • If you have been diagnosed with Dengue Hemorrhagic Fever (DHF) you must wait 12 months before donating.
  • There may still be a risk of malaria infection after this time so that a malaria antibody test will be done when you return to donate. If the test is negative, you will be able to continue to donate whole blood. If the test is positive, you will be notified with a letter and while you will no longer be able to donate whole blood, you will still be eligible to donate plasma by apheresis.
  • Please contact us on 0800 GIVE BLOOD (0800 448 325) to book an appointment and ask to speak with a nurse if you have any further questions regarding eligibility.

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.
