Quick questions on Disease dilemmas: distribution, diffusion, development and management - OCR A-Level Geography
3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is diffusion?Show answer
Disease spreads through diffusion, and the type shapes the spatial pattern. Expansion diffusion spreads a disease outward while the source stays affected, subdivided into contagious diffusion (spread by proximity and contact, producing clusters) and hierarchical diffusion (jumping down the settlement hierarchy, from major cities outward, often via air travel). Relocation diffusion carries disease with migrants, leaving the origin. Barriers (distance, quarantine, physical features, immunity) slow or distort diffusion.
