Updated Nov 13, 2026 ## Key points - Main risks: tuberculosis (aerosols), hepatitis B and C and HIV (cuts and needle-sticks), prions (resistant to formalin and routine disinfection). - Every body is treated as potentially infectious (standard precautions). - Protective equipment: cap, visor or goggles, mask, gown, waterproof apron, boots, gloves (double gloves; cut-resistant glove on the non-dominant hand). - Suspected tuberculosis: at least an N95 respirator (CDC); room with negative pressure and air exhausted to the outside. - Hepatitis B vaccine for all autopsy staff; unvaccinated staff should not take part. - Suspected prion disease: disposable instruments where possible and special decontamination. ## What it is The autopsy is a high-risk procedure for infection. A review of health and safety at necropsy names tuberculosis, the hepatitis B and C viruses, HIV and prions (the agents of Creutzfeldt-Jakob disease) as the main hazards. Tuberculosis spreads through aerosols, above all from power saws and from handling the lungs; pathologists have had more tuberculosis than other doctors, and bacilli have been recovered from autopsy room surfaces up to a day after a case. Blood-borne viruses are transmitted mostly by cuts and needle-stick injuries, usually to the non-dominant hand, and HIV can remain viable for days after death. Prions resist formalin and routine disinfection. Protection rests on treating every body as potentially infectious: personal protective equipment, careful handling of sharp instruments, ventilation, vaccination against hepatitis B and special measures for high-risk cases. ## Key facts - Aerosols come mainly from power saws, from washing with high-pressure sprays and from opening the bowel; the bowel can be opened under water. - Most cuts happen to the non-dominant hand; never pass instruments hand to hand and avoid sharp-pointed blades. - After a tuberculosis case, staff keep their respirators on until the room air has been changed (CDC). - A high-risk case is done only when needed, with as few people as possible. - Staff with open wounds, skin lesions or immunosuppression should not perform high-risk cases. - A sharp injury is reported and managed at once as an occupational exposure. ## Next step: what to do and document - Ask about known or suspected tuberculosis, HIV, hepatitis or prion disease before the autopsy and plan the precautions. - Wear full protective equipment and, if tuberculosis is possible, a fitted N95 respirator or better. - After any cut or needle-stick, wash the wound, report it at once and follow the institution's post-exposure protocol. - Report positive findings of diseases of public-health importance to the health authority (Decreto 786 de 1990, art. 32). - Dispose of waste and sharp instruments in the designated containers and disinfect surfaces after each case. ## Legal framework in Colombia - Decreto 786 de 1990 (art. 27) sets minimum conditions for any autopsy room: privacy, lighting, running water, ventilation, an autopsy table and electricity; in exceptional circumstances it allows a suitable table and no electricity or running water. - Art. 30 obliges hospitals, clinics and cemeteries to build or adapt autopsy rooms; without them the health authority does not issue or renew their licence. - Art. 32 requires notifying the health authority of positive results for diseases of epidemiological importance. - Official text checked on 2026-11-13 at funcionpublica.gov.co. ## Test yourself Think of the answer, then tap the question to see it. ## Which infection is mainly transmitted by aerosols in the autopsy room? Tuberculosis; aerosols come above all from power saws and handling of the lungs. ## What is the main route of HIV and hepatitis transmission to autopsy staff? Cuts and needle-stick injuries, most often to the non-dominant hand. ## Why do prions need special precautions? Because they are not inactivated by formalin or routine disinfection, so disposable instruments and special decontamination are used. ## What respiratory protection does the CDC recommend for an autopsy with suspected tuberculosis? At least an N95 respirator, and a higher level (such as a powered air-purifying respirator) if the risk assessment supports it.
