Abstract: The present disclosure provides a monitoring, tracing, early-warning and control system and method for virus spreading in a building. Indoor and outdoor environmental parameters of the building can be monitored in real time. Human physiological indexes are obtained in real time to determine a human health state, and moving trajectories of people and droplet spreading trajectories are obtained. Therefore, suspected infected persons and their close contacts are timely and accurately identified, and countermeasures are taken for the suspected infected persons and the close contacts. In addition, a spreading risk in a current indoor environment can be assessed, the indoor environment is ventilated and purified according to a spreading risk assessment result, and local areas of the suspected infected persons and the close contacts are effectively ventilated and purified, so as to reduce the spreading risk.
