Identification

Tuberculosis is a dangerous and potentially fatal disease; it is caused by a specific type of bacteria, which attacks the lungs. According to ScienceDaily.com, it affects over nine million people each year.

Transmission

Tuberculosis is spread through the air. When an infected person breathes, talks, coughs or sneezes, they send tiny droplets containing the bacteria into the air. Anyone who inhales these droplets may become infected with tuberculosis.

Solution

A recent study published in PLoS Medicine reveals that a specific type of ultraviolet lights can actually reduce the spread of tuberculosis through the air. Ultraviolet C lights have actually been shown to kill or inactivate the bacteria in the air.

In-Room Installation

These UV lights should be mounted at an elevation of at least 7 feet, to ensure that the ultraviolet exposure is not too much for the people in the room. The room should also have an efficient ventilation system to ensure the air moves through the room properly.

Duct Installation

The UV lights can also be mounted inside an air duct, perpendicular to the flow of air. The exposure, number and spacing of the UV lights used depends entirely on the amount of air flow.
