Methods for estimating HIV incidence
The prevalence of HIV has been used for many years to assess epidemic patterns and trends. However, it is increasingly difficult to interpret prevalence data because of changes in the survival period from infection to death as a result of the increased provision of antiretroviral therapy. The incidence of HIV infection, the rate at which new infections are acquired over a defined time period, i...
متن کاملTesting for Recent Infection to Estimate HIV Incidence from Single Cross-Sectional Surveys
The first SACEMA Quarterly update of 2010 was devoted to the topic of HIV incidence (the rate of occurrence of new infections in a population). Incidence will always remain a crucial measure in epidemiology, providing a direct and current indication of the spread of disease. Prevalence (the fraction of the population with a condition at a point in time) is a metric more commonly measured, but i...
متن کاملEstimating HIV incidence among key affected populations in China from serial cross-sectional surveys in 2010-2014.
INTRODUCTION HIV incidence is an important measure for monitoring the development of the epidemic, but it is difficult to ascertain. We combined serial HIV prevalence and mortality data to estimate HIV incidence among key affected populations (KAPs) in China. METHODS Serial cross-sectional surveys were conducted among KAPs from 2010 to 2014. Trends in HIV prevalence were assessed by the Cochr...
متن کاملEstimating cohort health expectancies from cross-sectional surveys of disability.
A life history can be regarded as a random process that evolves with age through various states of health before terminating with absorption into the state of death. Health expectancies are the occupation times of the non-absorbing states and their estimation is of interest. A continuing major problem has been the lack of satisfactory longitudinal data on which to base estimates and as a result...
متن کاملEstimating HIV-1 Fitness Characteristics from Cross-Sectional Genotype Data
Despite the success of highly active antiretroviral therapy (HAART) in the management of human immunodeficiency virus (HIV)-1 infection, virological failure due to drug resistance development remains a major challenge. Resistant mutants display reduced drug susceptibilities, but in the absence of drug, they generally have a lower fitness than the wild type, owing to a mutation-incurred cost. Th...
