A biological sample collection, storage, and transport device includes a collection assembly and a sheath, wherein the collection assembly includes a support shaft, a swab head, and a handle, the swab head mechanically couples to a distal support shaft end, the handle couples to a proximal support shaft end, and the collection assembly slideably couples to the sheath and is configurable in a retracted position with the swab head entirely disposed within the sheath or an extended position with the swab head extending outside of the sheath. A distal sheath end includes an aperture, the aperture having a circumference large enough to allow the swab head to pass through said aperture when the collection assembly is configured in the extended position, and a seal is applied to the distal sheath end after the swab head has collected a biological sample and the collection assembly has been reconfigured into the retracted position.
