Shedding of McHV-1 in rhesus macaque saliva samples collected using 121 oral swabs and quantified on the basis of observational data and rPCR positivity for McHV-1 DNA, by social group, by season, Silver Springs State Park, Florida, USA, 2015–2016*
| Season | Group 1 |

*McHV-1, macacine herpesvirus 1; rPCR, real-time PCR.
†These 3 saliva samples represent 2 or 3 unique macaques. We estimated a conservative prevalence of 7% (95% CI 2%–22%) assuming the 3 positive oral swabs came from 2 animals and all 29 animals were sampled. Taking the least conservative approach, we estimated a prevalence of 30% (95% CI 11%–60%) if the 3 swabs came from 3 unique animals and only 10 animals were sampled.
