FAIRFAX, Va. (WUSA9) -- Tuberculosis test results starting coming in for the Lee High School Students who were tested at the special school clinic set up last week.
Lee High rising junior Danielle Klinekert went back for her results today and says they were negative, but she is supposed to retested in August.
Her cousin went in for testing today after receiving the letter send to 430 Lee students who may have been exposed to one of three people at Lee who had active TB. She says she thinks she knows who may have had active TB, the person in her English class who coughed a lot.
It's not easy to become infected with TB.
It takes being around a person with an active case inside, in close quarters, for at least a 24 hour period. Sunlight kills the bacteria, says Dr. Gloria Addo-Ayensu, the Fairfax County Health Director.
Since one-third of the world's population is infected with TB, Addo-Ayensu says they expect to find some latent TB cases, but if more cases than expected are found at Lee, they'll test more students while encouraging treatment for those infected.
She says one person with active TB can infect 20 people.
Testing at Lee High School continues through Wednesday and results will be handed out through Friday.
For those students among the 430 who are out of town this week, or failed to come for testing, they will be encouraged to go to a Fairfax County Health Department Clinic to be tested.
