FORT LEONARD WOOD, Mo. — Pfc. Marley Bell from the Consolidated Troop Medical Clinic performs a COVID-19 test Jan. 7 at Nutter Field House. More than 50 Fort Leonard Wood medical personnel tested nearly 7,000 trainees and cadre who recently returned from holiday block leave travel. As an added precaution, each trainee and cadre was tested twice during their first week back, as COVID-19 cases may be too early in the disease process to be picked up by the initial test. The nasal swab being used provided on-the-spot positive or negative confirmation of the virus' presence in about 15 minutes.
