SIVgor-infected gorilla capture and recapture (via sampling) in the Campo Ma'an study area. From April 2004 to November 2011, an area of approximately 200 km² was covered during successive field missions in the Campo Ma'an National Park. The 11 SIVgor-positive individuals that were captured and recaptured (via sampling) in at least two different collection missions (Table 2) were plotted and are identified by ID numbers, with a positive sign for those found to be SIV seropositive and a negative sign for those that were first found to be SIV negative (ID32 and ID36).
