At a dedicated Malaria Summit at the time of the 2018 Commonwealth Heads of Government Meeting in London, His Royal Highness spoke of the need for immediate action to combat malaria:
“I've been lucky enough to travel throughout the Commonwealth and have only too often witnessed at first hand the devastation that malaria can wreak on communities… Combating malaria is, without doubt, an issue of truly global urgency and I’m encouraged and inspired to see how real the determination of the international community is to overcome this dreadful disease.
