Models for the Spread of Infection via Pairing at Parties
- 649 Downloads
This chapter considers some algebraically tractable population models for the spread of infection through the formation of pairs of individuals; a further infection is produced if a pair consists of a susceptible and an infective. The closest “classical” analogue is the so-called simple epidemic with infection and no recovery, operating in discrete time. The models may help us to understand the spread of infection due to needle-sharing in small groups, as, for example, in the spread of the human immunodeficiency virus (HIV) among intravenous drug users (IVDUs).
