Students and staff at Cal State San Marcos may have been exposed to tuberculosis this fall semester, the San Diego County Health and Human Services Agency announced Wednesday.

HHSA Public Health Services and CSUSM officials have worked together to identify and notify those who had a higher risk of exposure to tuberculosis and will be providing no-cost testing to individuals at increased risk for infection. The period of exposure was from Aug. 30 to Nov. 8.

"Symptoms of active TB include persistent cough, fever, night sweats and unexplained weight loss," said Dr. Wilma J. Wooten, county public health officer. "Most people who become infected after exposure to tuberculosis do not get sick right away. Some who become infected with tuberculosis will become ill at some point in the future, sometimes even years later.

"Blood tests and skin tests are effective to determine whether someone has been infected," she said. "All those notified of a high risk of exposure are encouraged to receive no-cost testing."
