3. Swab a pustule/lesion vigorously without unroofing or lancing the lesion.
4. Insert the swab into the viral transport medium without touching the outside of the collection tube, and break off the end of the swab, if required.
5. Screw the top of the collection tube back on tightly. Leaking specimens will be rejected.
