This is a reply to Dr Gaydos and colleagues following their comments on our paper 'Prevalence of Chlamydial and Gonococcal Infections among Young Adults', Journal of the American Medical Association, May 12, 2004, 291 (18):2229-2236. DOI: …
Sexually-transmitted diseases (STDs) constitute a major public health concern. Mathematical models for the transmission dynamics of STDs indicate that heterogeneity in sexual activity level allow them to persist even when the typical behavior of the …
Context: Chlamydial and gonococcal infections are important causes of pelvic inflammatory disease, ectopic pregnancy, and infertility. Although screening for Chlamydia trachomatis is widely recommended among young adult women, little information is …
Objectives: We estimated HIV prevalence rates among young adults in the United States. Methods: We used survey data from the third wave of the National Longitudinal Study of Adolescent Health, a random sample of nearly 19000 young adults initiated in …
Our aim was to develop a statistical method to correct for non-parallelism in an estrone-3-glucuronide (E1G) enzyme immunoassay (EIA). Non-parallelism of serially diluted urine specimens with a calibration curve was demonstrated in an EIA for E1G. A …
Distributions of the number of sexual partners reported in surveys show a pronounced skew, with most people having had one or no partners in the past year and a small fraction having had many. Liljeros and colleagues infer from the results of a …
Recent work has focused attention on statistical inference for the population distribution of the number of sexual partners based on survey data. The characteristics of these distributions are of interest as components of mathematical models for the …
Recent research into the properties of human sexual–contact networks has suggested that the degree distribution of the contact graph exhibits power–law scaling. One notable property of this power–law scaling is that the epidemic threshold for the …
Epidemic thresholds in network models of heterogeneous populations characterized by highly right-skewed contact distributions can be very small. When the population is above the threshold, an epidemic is inevitable and conventional control measures …
