Previous studies on climate change have primarily focused on how new and altered transmission patterns of zoonotic infections, such as malaria, may increase the risk of transfusion-transmitted infections (TTIs) and lead to more donor deferrals. However, researchers from Australia highlight that climate change affects every stage of the blood supply including donor heath, collection logistics, processing and storage, and distribution. A multipronged approach will be necessary to ensure a stable blood supply in the face of changing patterns of zoonotic infections, extreme weather events such as fires and hurricanes, and indirect risks like increased respiratory disorders and trauma-related injuries. Key strategies will include flexible and adaptable emergency preparedness plans, enhanced serosurveillance of TTIs, utilization of back-up power sources, robust inventory systems, management protocols to prioritize critical needs, and potentially the use of drones and walking blood banks. Further research on climate change preparedness will be critical to ensuring a safe and stable blood supply in the future.
