Evaluation of the Malaria Surveillance System in Kaduna State, Nigeria 2016

Malaria is a parasitic disease caused by Plasmodium falciparum. About 3.2 billion people worldwide are at risk of malaria. Children and pregnant women are particularly vulnerable to the disease. Sub- Saharan Africa carries a high share of the global malaria burden. Effective malaria surveillance system is essential in the control and elimination of malaria. Worldwide, there were an estimated 198 million cases of malaria in 2013 and 584,000 deaths.

Estimating spatial patterning of dietary behaviors using grocery transaction data

Unhealthy diet is becoming the most important preventable cause of chronic disease burden. Dietary patterns vary across neighborhoods as a function of policy, marketing, social support, economy, and the commercial food environment. Assessment of community-specific response to these socio-ecological factors is critical for the development and evaluation policy interventions and identification of nutrition inequality.

Factors associated with immunization of children in Kaduna State, Nigeria, 2016

Immunization is one of the safest and most effective interventions to prevent disease and early child death. Although, about three quarters of the world’s child population is reached with the required vaccines, only half of the children in Sub-Saharan Africa get access to basic immunization. A substantial number of children worldwide do not complete immunization schedules because neither health services nor conventional communication mechanisms regularly reach their communities.

Facilitating Public Health Action through Surveillance Dashboards

Traditionally, public health surveillance departments collect, analyze, interpret, and package information into static surveillance reports for distribution to stakeholders. This resource-intensive production and dissemination process has major shortcomings that impede end users from optimally utilizing this information for public health action. Often, by the time traditional reports are ready for dissemination they are outdated. Information can be difficult to find in long static reports and there is no capability to interact with the data by users.

Facile Dashboard Creation Using Library of Syndromic Surveillance Visualization Tools

Public health surveillance largely relies on the use of surveillance systems to facilitate the identification and investigation of epidemiologic concerns reflected in data. In order to support public health response, these systems must present relevant information, and be user-friendly, dynamic, and easily-implementable. The abundance of R tools freely-available online for data analysis and visualization presents not only opportunities but also challenges for adoption in that these tools must be integrated so as to allow a structured workflow.

Firearm Injury Encounters in the Veterans Health Administration (VHA), 2010-2015

Firearm violence is an issue of public health concern leading to more than 30,000 deaths and 80,000 nonfatal injuries in the United States annually. To date, firearm-related studies among Veterans have focused primarily on suicide and attempted suicide. Herein, we examine firearm violence among VHA enrollees for all manners/ intents, including assault, unintentional, self-inflicted, undetermined and other firearm-related injury encounters in both the inpatient and outpatient settings.

Sero-Prevalence of Rubella Virus among Pregnant Women in Kaduna State Nigeria 2015

Rubella virus causes -“German measles,” also known as “three-day measles.” This is usually a milder disease than red measles. Red/Hard measles or just measles is caused by Rubeola virus. The result of acute infection of the virus is a benign systematic rash which is significantly pathogenic to humans. This virus is a, positive-strand RNA virus that replicates in the cytoplasm of the infected cell. (Brooks et al., 2007).

Characterizing Fentanyl-Associated Mortality using the Literal Causes of Death

In October 2015, the Centers for Disease Control and Prevention (CDC) released health advisory #384 to inform people about increases in fentanyl fatalities. Florida’s statewide syndromic surveillance system, Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE-FL), captures electronic death record data in near real time which allows for the monitoring of mortality trends across the state.

Carbon Monoxide Poisoning in the Veterans Health Administration, 2010 - 2016

It is estimated that in the United States (US), unintentional non-fire related CO poisoning causes an average of 439 deaths annually, and in 2007 confirmed CO poisoning cases resulted in 21,304 ED visits and 2,302 hospitalizations (71 per million and 8 per million population, respectively)1 . Despite the significant risk of morbidity and mortality associated with CO poisoning, existing surveillance systems in the United States are limited. This study is the first to focus specifically on CO poisoning trends within the VHA population.
