It has social groups of four to twelve individuals. == Disease == Sooty mangabeys are naturally infected with a strain of Simian Immunodeficiency Virus (SIV). Due to extensive human-mangabey contact in [[sub-Saharan Africa]], the virus has [[zoonosis|jumped from this species]] into [[human]]s on many occasions. This resulted in the [[HIV#HIV-2|HIV-2]] [[virus]]. The [[HIV|HIV-1]] strain by contrast came from the [[common chimpanzee]] strain of SIV.<ref>{{cite journal | author = Binhua Ling |display-authors = etal | doi = 10.1128/JVI.78.16.8902-8908.2004 | title = Classic AIDS in a sooty mangabey after an 18-year natural infection | journal = J.
