Click to place a human. The first human you spawn will be sick. The humans cannot walk through black walls. If they touch someone sick they will get sick after a few seconds then will die or become immune after a few seconds. The higher the death rate the fewer people will die and the lower the more. If a human touches the clinic they will become immune for up to a minute. Also, people die from natural causes after 100-250seconds.
