The global humanitarian system is mounting a robust, swift, and appropriate response. Some aid will be remote to respect Tonga's COVID-free policies, while resources like safe drinking water will need to be delivered on-site.
This global response must be sensitive. Tonga is nearly COVID-free and aid agencies must avoid bringing the virus. Responders must also consider that the Pacific Island community has just faced cyclone-related natural disasters.
