ArticlePublication 2017Using Data-Driven Agent-Based Models to Forecast Emerging Infectious Diseases
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which …
This paper describes an agent-based model framework developed to forecast the 2014-15 Ebola epidemic, which was subsequently used in the Ebola forecasting challenge. Producing timely and reliable forecasts for an epidemic of an emerging infectious disease is a challenge. Epidemiologists and policy makers have to deal with poor data quality, limited understanding of the disease dynamics, a rapidly changing social environment and the uncertainty around the effects of various interventions in place. In this setting,…

ArticlePublication 2013Validation and Calibration of a Simulation Model of Pediatric HIV Infection
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of …
The authors developed a microsimulation model of pediatric HIV disease progression using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) model framework. This CEPAC-Pediatric model was then validated by varying CD4 data and comparing the corresponding model-generated survival curves to empirical survival curves obtained from the International Epidemiologic Database to Evaluate AIDS (IeDEA). The model was calibrated to other African countries by systematically varying immunologic and HIV mortality-related input parameters. In the calibration analyses, the model-generated…

ArticlePublication 2011Health and Economic Impact of HPV 16/18 Vaccination and Cervical Cancer Screening in Eastern Africa
In this article the authors use epidemiologic data from Kenya, Mozambique, Tanzania, Uganda, and Zimbabwe …
In this article the authors use epidemiologic data from Kenya, Mozambique, Tanzania, Uganda, and Zimbabwe to develop models of HPV-related infection and disease. For each country, they assessed HPV vaccination of girls before age 12 followed by screening with HPV DNA testing once, twice, or three times per lifetime (at ages 35, 40, 45). For women over age 30, they assessed only screening (with HPV DNA testing up to three times per lifetime or VIA…

ArticlePublication 2024Hepatitis C Elimination in Rwanda: Progress, Feasibility, Economic Evaluation
This study evaluates the impact of Rwanda's national program launched in 2018 to eliminate hepatitis …
This study evaluates the impact of Rwanda's national program launched in 2018 to eliminate hepatitis C virus (HCV) and identifies strategies to achieve World Health Organization (WHO) elimination goals by 2030. Employing a microsimulation model spanning 2015 to 2050, the analysis assesses HCV epidemic trends, prevalence, mortality, and total care costs under various scenarios. Results show that between 2018 and 2022, over 7 million people were screened and 60,000 treated, projecting Rwanda's potential achievement of…

ArticlePublication 2022Re-Evaluating the Health Impact and Cost-Effectiveness of Tuberculosis Prevention for Modern ART Cohorts
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in …
TB preventive therapy (TPT) is widely accepted to be cost-effective for reducing TB incidence in HIV-infected individuals receiving antiretroviral therapy (ART). However, as individuals initiate ART earlier in the course of disease, TB incidence is lower, and it is unclear how ART cost-effectiveness has changed. This study assessed the cost-effectiveness of TPT in contemporary ART cohorts. The authors developed a microsimulation model of TB and HIV and parameterised it using data from a large HIV…

ArticlePublication 2017Estimated Economic Impact of Vaccinations in 73 LMIC, 2001-2020
This analysis estimates the economic impact likely to be achieved by efforts to vaccinate against 10 …
This analysis estimates the economic impact likely to be achieved by efforts to vaccinate against 10 vaccine-preventable diseases between 2001 and 2020 in 73 low- and middle-income countries largely supported by Gavi, the Vaccine Alliance. The authors used health impact models to estimate the economic impact of achieving forecasted coverages for vaccination against Haemophilus influenzae type b, hepatitis B, human papillomavirus, Japanese encephalitis, measles, Neisseria meningitidis serogroup A, rotavirus, rubella, Streptococcus pneumoniae and yellow fever. In…

ArticlePublication 2016Cost-Effectiveness of Diagnosing HIV Infection During Early Infancy in South Africa
In this study the clinical impact and cost-effectiveness of four different early infant HIV diagnosis …
In this study the clinical impact and cost-effectiveness of four different early infant HIV diagnosis (EID) testing strategies for HIV-exposed infants in South Africa were compared using a microsimulation model. The strategies included (1) no EID (diagnosis only after illness), (2) and (3) testing once (at birth alone or at 6 weeks of age alone), and (4) testing twice (at birth and 6 weeks of age). Findings showed that the testing at birth alone strategy…

ArticlePublication 2015Cost-Effectiveness of First-Line Antiretroviral Therapy for HIV-Infected African Children Less Than 3 Years of Age
This article compares the cost-effectiveness of different strategies of first-line antiretroviral therapy (no ART, first-line nevirapine …
This article compares the cost-effectiveness of different strategies of first-line antiretroviral therapy (no ART, first-line nevirapine with second-line lopinavir/ritonavir, and first-line lopinavir/ritonavir with second-line nevirapine) for HIV-infected children less than 3 years of age in Africa, using the Cost-Effectiveness of Preventing AIDS Complications- Pediatric model and data obtained from the International Maternal, Pediatric, and Adolescent Clinical Trial P1060 trial. Results demonstrated that both ART regimens were very cost-effective compared to no ART. First-line lopinavir/ritonavir led to longer…

ArticlePublication 2014Cost-Effectiveness of Female HPV Vaccination in 179 Countries: A PRIME Modelling Study
The authors present a simple generic model, Papillomavirus Rapid Interface for Modelling and Economics (PRIME), …
The authors present a simple generic model, Papillomavirus Rapid Interface for Modelling and Economics (PRIME), used to assess cost-effectiveness and health effects of vaccination of girls against HPV before sexual debut in terms of burden of cervical cancer and mortality. The PRIME models incidence according to proposed vaccine efficacy against HPV 16/18, vaccine coverage, cervical cancer incidence and mortality, and HPV type distribution. It assumes lifelong vaccine protection and no changes to other screening programs…
