A bandaging device and method for sequestering a wound or an inoculation site on a patient are provided. The device comprises a body integrally formed to encase the wound or inoculation site. The formed body comprises a substantially transparent top portion for visually inspecting the wound or inoculation site, a side portion descending from the top portion to a lower edge, and a flange extending radially outward from the lower edge. The bandaging device is formed from a material that is substantially liquid-impermeable to prevent liquid or other contaminants from reaching the wound or inoculation site. The bandaging device also comprises at least one section that is formed from a material that is substantially liquid-impermeable and vapor-permeable to allow vapor to reach the wound or inoculation site while preventing liquid or other contaminants from contacting therewith.
