ABSTRACT An innovative student-to-student peer mentoring teaching strategy was used to deliver health care to at-risk populations in a community-based setting.
The function [THETA](t) represents the daily baseline hazard function multiplied by the effects of time-varying individual covariates averaged over the at-risk population. First, it is reasonable to model [R.sup.(l)](t) as a smooth function in time because it is a summation of the individual covariate effects over the at-risk population in the lth strata.
Depletion of the at-risk population acts to flatten the exposure--response mortality curve.
'Periodic treatment of at-risk populations will cure mild symptoms and also prevent infected people from developing severe, late-stage chronic disease,'' he said.

Dr Cheema, director of the Institute for Population Health and assistant professor of healthcare policy and research, said:"The consensus is that the best way to eliminate HCV infection is to focus interventions on at-risk populations, such as people who inject drugs, people who have had blood transfusions, prisoners, and people who engage in risky sexual practices, among others." "Unfortunately, many of the systematic reviews of HCV in the MENA region use data from mixed populations at differing risk of exposure to HCV, rather than targeted sub-sections of the population.
