Trinidad & Tobago : Hiv Epidemic, Madison Caldwell Jan 2017

Trinidad & Tobago : Hiv Epidemic, Madison Caldwell

Global Public Health

Trinidad and Tobago are twin islands located in the Caribbean off the coast of Venezuela. In the recent years since about 1990, citizens of this country have been greatly affected by the HIV epidemic. HIV stands for human immunodeficiency virus and is spread through infected seman, blood, or vaginal fluids usually through sexual intercourse. As this virus continues to progress in the body, it will eventually turn into AIDS, which stands for acquired immunodeficiency syndrome. Once HIV progresses to AIDS, the outcome is ultimately fatal, hence why there is a dire need to promote awareness and methods of intervention to …


Chad : Hepatitis E, Hanna Pegarsch Jan 2017

Chad : Hepatitis E, Hanna Pegarsch

Global Public Health

Contaminated drinking water in Chad is the main source for a Hepatitis E outbreak, leading Chad citizens to develop severe illness including jaundice, liver-failure, miscarriage, and death. There are 0.4 physicians for every 10,000 people living in Chad needing healthcare. Of the citizens in Chad, only 42% have access to uncontaminated drinking water. With such a long incubation period for Hepatitis E, the citizens don’t know they are spreading the illness to the rest of their community. Even with the symptoms, the citizens don’t have the access or the capacity for treatment, making Hepatitis E an epidemic in Chad.

Manuscripts, Articles, Book Chapters and Other Papers

We analyzed prevention of mother-to-child transmission (PMTCT) data from a retrospective cohort of n = 1365 HIV+ mothers who enrolled their HIV-exposed infants in early infant diagnosis services in four Kenyan government hospitals from 2010 to 2012. Less than 15 and 20 % of mother-infant pairs were provided with regimens that met WHO Option A and B/B+ guidelines, respectively. Annually, the gestational age at treatment initiation decreased, while uptake of Option B/B+ increased (all p's < 0.001). Pediatric HIV infection was halved (8.6-4.3 %), yet varied significantly by hospital. In multivariable analyses, HIV-exposed infants who received no PMTCT (AOR 4.6 [2.49, 8.62], p < 0.001), mixed foods (AOR 5.0 [2.77, 9.02], p < 0.001), and care at one of the four hospitals (AOR 3.0 [1.51, 5.92], p = 0.002) were more likely to be HIV-infected. While the administration and uptake of WHO PMTCT guidelines is improving, an expanded focus on retention and medication adherence will further reduce pediatric HIV transmission.

Testing Modeling Assumptions In The West Africa Ebola Outbreak, Matthew C. Ingram, Keith Burghardt, Christopher Verzijl, Junming Huang, Binyang Song, Marie-Pierre Hasne

Political Science Faculty Scholarship

The Ebola virus in West Africa has infected almost 30,000 and killed over 11,000 people. Recent models of Ebola Virus Disease (EVD) have often made assumptions about how the disease spreads, such as uniform transmissibility and homogeneous mixing within a population. In this paper, we test whether these assumptions are necessarily correct, and offer simple solutions that may improve disease model accuracy. First, we use data and models of West African migration to show that EVD does not homogeneously mix, but spreads in a predictable manner. Next, we estimate the initial growth rate of EVD within country administrative divisions and …

A Generalized-Growth Model To Characterize The Early Ascending Phase Of Infectious Disease Outbreaks, Cecile Viboud, Lone Simonsen, Gerardo Chowell

Global Health Faculty Publications

Background

A better characterization of the early growth dynamics of an epidemic is needed to dissect the important drivers of disease transmission, refine existing transmission models, and improve disease forecasts.

Materials and methods

We introduce a 2-parameter generalized-growth model to characterize the ascending phase of an outbreak and capture epidemic profiles ranging from sub-exponential to exponential growth. We test the model against empirical outbreak data representing a variety of viral pathogens in historic and contemporary populations, and provide simulations highlighting the importance of sub-exponential growth for forecasting purposes.

Results

We applied the generalized-growth model to 20 infectious disease outbreaks representing …
