Description

Integrated response system and method for biological hazards The present invention relates to an integrated response system and method for biological hazardous agents, and more specifically, to an integrated response system and method for biological hazardous agents capable of preventing the spread of biological hazardous agents while tracking the risk of spread of biological hazardous agents in a closed indoor space. The transmission of viral diseases in indoor spaces primarily occurs through airborne transmission, which is particularly true for airborne viruses such as COVID-19. Conventionally, to assess the risk of transmission of biological hazardous agents in indoor environments, infection risk values have been calculated using indicators such as carbon dioxide concentration, relative humidity, fine particle concentration, and temperature, and based on this, the risk of infection caused by the transmission of biological hazardous agents in indoor environments has been evaluated. Meanwhile, the actual risk of transmission of biological hazards in indoor environments is significantly influenced by human infection information related to the health status of occupants. Therefore, there is a need to develop a system that prevents the transmission of biological hazards in indoor spaces by comprehensively considering these factors and more accurately assessing the risk of infection in indoor spaces.
