UV Light Used to Disinfect School After Outbreak
NOVEMBER 02, 2015


The staff at Milton High School in Wisconsin took extra precaution by using ultraviolet (UV) machines as a cleaning measure after a cryptosporidium outbreak hit the school last week.

The building and grounds crews used the lights in the school's common areas in addition to other high-risk areas for infection, such as locker rooms, according to a story on WKOW.com.

"While our building and grounds department does an excellent job of keeping them regularly clean," said Jerry Schuetz, the district's communications supervisor, "given the info we had about the couple cases at the high school, we put [the lights] in those common areas in an effort to ensure they were extra sterile."


QUESTION: What type of lights/process are involved in killing organisms over wide areas such as described here? I've never heard of this.

The lights are UV but in a different range than used for urine detection.

UV has been used for disinfecting for some time. But it is a rather slow process. Depending upon the distance from the light to the object being sanitized, the time may be 20 minutes or a couple hours. Some hospitals sue this on patient rooms between patients.

In cases such as the article, multiple lights are used and moved throughout the process. Keep close to high touch surfaces such as door knobs, light switches, water fountains, etc.

it would be nice to have locker rooms with lights that once you turned off the regular lights the uv lights came on, wouldn't have to be super powerful but enough that it could do good over 4-8 hr period.

Intense UV light is used in hospitals to minimize microorganisms.
