Network structure plays a critical role in channeling person-to-person transmission of
infectious disease agents like HIV. Stochastic simulations are used here to examine the …

This paper explores the roles of acute infection and concurrent partnerships in HIV
transmission dynamics among young adults in Zimbabwe using realistic representations of …

Mathematical modeling of transmission dynamics of sexually transmitted infections (STIs)
and HIV has considerably advanced HIV research by highlighting the importance of certain …

The spread of a disease through human populations can be significantly altered by
patterned networks of social contact. Largely in response to AIDS, the way in which social …

Sub-Saharan Africa contains only 3% of the global population but an alarming 68% of the
world's adults and children living with HIV/AIDS (UNAIDS 2007). Sixtyeight percent of adults …

The combination of long-term concurrent sexual partnerships and high infectiousness early
in HIV infection has been suggested as a key driver of the extensive spread of HIV in …

Early theoretical and empirical studies of the sexual transmission of HIV focused on
numbers of sexual partners as a key variable [1, 2]. For individuals this dominates the risk of …

Background: Sexual partnerships between people at higher and lower risk for sexually
transmitted infections (STIs)(ie, bridging) occur through dissortative mixing and concurrent …

This paper examines the potential impact of concurrent partnerships on HIV spread in
Uganda using microsimulation. We represent a population of individuals, the sexual …

The combination of two factors gives early HIV infection an especially strong influence on
transmission dynamics:(a) increased transmission probabilities and (b) increased …
