CATEGORY B2 PATHOGENS

Materials in this category require special conditions for containment but do not require special accommodation. They include:

• All specimens known to be Hepatitis B surface antigen positive.
• All specimens from patients in renal units who have not been screened.
• All specimens from patients suffering from infective, or suspected infective, diseases of the liver.
• All specimens from patients with defective or altered immunological competence, e.g. with leukaemia or Down syndrome.
• All specimens from patients in other `at risk' groups, e.g. drug addicts.
• All specimens from patients suffering from Creutzfeldt­Jakob disease, except for brain and spinal cord which is in Category B1.
