Human Sexual Networks
Human sexual networks are the network structures that emerge when individuals have sexual contact with each other. In general, use of the term “sexual contact” is restricted in this entry to mean vaginal or anal intercourse or oral sex – contacts by which sexually transmitted infections (STIs) can be transmitted. Sexual networks are important because an understanding of their structure and how they facilitate the spread of infection can help us understand how the spread of this type of infection can best be prevented.
Although the type of contact that spreads STIs occurs less frequently than is the case for most other types of contact that spread disease, the spread of STIs has turned out to be surprisingly hard to limit. The difficulties in getting STIs under control have led to an interest in sexual contact patterns (Liljeros et al. 2003; Morris 2004; Morris et al. 2007). In this entry, we discuss a variety of explanations related to the structural properties...
