For dealing with infected cases, autopsy laboratories should be constructed in the future to be qualified at certain biological safety levels (P1–P4) [13]. The P3 autopsy laboratory would satisfy the requirements for most of the infectious diseases, with the special requirements in terms of floor layout, maintenance structure, ventilation and air conditioning system, water supply and air supply system, sewage disposal, and disinfection system. Each functional area of the autopsy laboratory must maintain a certain negative pressure and suction gradient to ensure no leak or reflux of contaminating air [14].
