Fig 1. Photograph composite of EVICT study site.

The EVICT study site was prepared with input from the Ministry of Health and Sanitation National Eye Programme, Sierra Leone input, along with guidance from Emory Ophthalmology, Infectious Diseases specialists, World Health Organization, and public health officials. A donning station was designed with powered air purifying respirator (PAPR) hoods, fluid impervious Tyvek suits, and shoe covers at the entryway to the procedure rom (A). The procedure room created from tarp partitions hooked from the ceiling, contained only the minimum necessary supplies for each ocular fluid sampling procedure with visibility to the donning area, marked by duct tape (B, black asterisks). A specimen window is on the wall of the tarp and duct tape (red asterisks) marks the doffing area for providers to exit via the transition zone. A specimen window is open to a clean area where ocular fluid samples are passed after double-bagging and disinfection of the specimen container (C). Visible signage for doffing is labeled and visible at the transition zone with a duct tape large arrow (D) with access to hand disinfection in the transition zone (E). An emergency shower facility is available in the event of contamination. Photographs A-D courtesy of Mr. Andrew Gess.
