Analysis of rapid reconstruction project of negative pressure biosafety level-2 laboratory against COVID-19

 The Sichuan Provincial People’s Hospital is a provincial designated diagnosis and treatment unit for COVID-19. Aiming at the most critical nucleic acid detection link for the diagnosis of COVID-19, based on the original biological laboratory, through the establishment of buffer rooms, mechanical ventilation systems, high-efficiency exhaust air filtration and high-temperature sterilization, the negative pressure laboratory has been successfully implemented. Reconstruction has won precious time for hospital prevention and control during the outbreak of the epidemic. Combined with the reconstruction example, the rapid reconstruction methods of negative pressure biosafety level-2 laboratories are analyzed and summarized, which provides reference for the reconstruction of similar projects and the establishment of standards for the construction of negative pressure biosafety level-2 laboratories in general hospitals.
