Overcrowding
Learning ObjectivesDiscuss overcrowding and increased population density as a risk factor for TB infection and disease.
Overcrowding is the situation where people located within a given space are more than what is considered tolerable from a safety and health perspective. Generally in living/ dwelling areas an measure of 50 square feet is the minimum requirement for space per person; less than this is considered overcrowding.
Calculating the floor space per person: The number of persons in the household divided by the total area of the house gives the floor space per person.
Overcrowding in households/ workspaces is proven to carry a high risk of TB transmission. This happens because an infected individual will disperse infective material to a smaller space, and thus increases the chance of a close contact inhaling infected particles.
The risk of TB Transmission due to reduced ventilation is greatly enhanced by over crowding.
