Regulations Governing Management of Infectious Biological Materials Article 3
Pathogens are classified into four risk groups by the hazardous level of their pathogenicity:1. Risk Group 1: such as Escherichia coli K-12, Adeno-associated virus and other pathogens that usually do not affect human health;2. Risk Group 2: such as Staphylococcus aureus, Hepatitis B virus, Plasmodium falciparum, and other pathogens that could produce mild effects on human health, and for which preventive or therapeutic interventions are usually available;3. Risk Group 3: such as Mycobacterium tuberculosis, Human immunodeficiency virus type 1 and type 2, and other pathogens that could produce serious effects on human health or may even be fatal, and for which preventive or therapeutic interventions are likely available;4. Risk Group 4: such as Ebola virus, Variola (major and minor) virus, and other pathogens that could produce serious effects on human health or may even be fatal, and for which preventive or therapeutic interventions are usually not available.

病原體，依其致病危害風險高低，分為四級危險群：
一、第一級：大腸桿菌K12型、腺相關病毒，及其他通常不影響人體健康者。
二、第二級：金黃色葡萄球菌、B型肝炎病毒、惡性瘧原蟲，及其他輕微影響人體健康，且通常有預防或治療方法者。
三、第三級：結核分枝桿菌、人類免疫缺乏病毒第一型與第二型，及其他嚴重影響人體健康或可能致死，且可能有預防或治療方法者。
四、第四級：伊波拉病毒、天花病毒，及其他嚴重影響人體健康或可能致死，且通常無預防及治療方法者。
