Dalam epidemiologi, jumlah pembiakan asas (kadang-kadang dipanggil nisbah pembiakan asas, atau kadar pembiakan asas tidak betul, dan dilambangkan R 0, tidak disebutkan) daripada jangkitan boleh dianggap sebagai bilangan kes yang satu kes menjana secara purata sepanjang perjalanannya tempoh berjangkit, dalam populasi yang tidak dijangkiti.[8]
Metrik ini berguna kerana ia membantu menentukan sama ada penyakit berjangkit dapat menyebar melalui populasi. Akar konsep pembiakan asas dapat dikesan melalui karya Alfred Lotka, Ronald Ross, dan lain-lain, tetapi aplikasi moden pertama dalam epidemiologi oleh George MacDonald pada tahun 1952, yang membina model populasi penyebaran malaria.
