Acute Hepatitis A Infection and Vaccination in the Veterans Health Administration

Since hepatitis A vaccination became widely recommended in the US in the mid-1990's, rates of acute hepatitis A virus (HAV) infection have steadily declined, however, since 2011, incidence of new cases of HAV appears to be increasing1, often linked with foodborne outbreaks and socio-economic trends such as homelessness and substance abuse.2 In 2016, the CDC reported vaccination coverage among adults aged > 19 was 9.5%, 19-49 was 13.4%, and > 50 was 5.4%3.

Study of The Mortality of Vaccine-Preventable Infections In Ukraine (1965– 2015)

Infectious diseases are still the cause of a large number of deaths in Ukraine. Analysis of infectious mortality allows the study of the dynamics of diseases that pose the greatest danger. In particular, those that are vaccine-preventable and suggest more effective methods for organizing an epidemic surveillance system.

Burden and Trend of Measles in Nigeria: Five-year Review Case-base Surveillance Data

Measles is a vaccine preventable, highly transmissible viral infection that affects mostly under-five year children. The disease is caused by a Morbillivirus; member of the Paramyxovirus family.


We reviewed measles specific Integretaged Disease Surveillance and Response (IDSR) data from Nigeria over a five-year period to highlights its burden and trends, and make recommendations for improvements.

Anthrax in Human and Livestock: Investigation and Response, Turkana-Kenya, 2012

Timely outbreak response requires effective early warning and surveillance systems. This investigation points out the important role that livestock keepers can play in veterinary surveillance. The investigation revealed that pastoralists had good traditional knowledge concerning livestock diseases in general and anthrax in particular. They provided detailed and accurate clinical descriptions of the disease, had greater appreciation of the risk factors associated with the disease, and showed a stronger recall of the outbreak history.

Rabies Vaccination Coverage and Antibody Profile of Owned Dogs in Abuja, Nigeria

Rabies is a zoonotic disease of high public health importance. There have been documented reports of rabies in vaccinated dogs. Rabies is enzootic in domestic dogs in Nigeria. Hence, annual vaccination campaigns of dogs are advocated with the aim of rabies elimination. Vaccination status, type of vaccination and the immunogenicity of the various rabies vaccines used in Abuja Nigeria has not been studied. To date, no effective medical therapy has been established for rabies.

Control and Cost-benefit Analysis of Fast Spreading Diseases: The case of Ebola

Mitigating the spread of infectious disease is of great importance for policy makers. Taking the recent outbreak of Ebola as an example, it was difficult for policy makers to identify the best course of action based on the cost-effectiveness of what was available. In effort to address the needs of policy makers to mitigate the spread of infectious disease before an outbreak becomes uncontrollable, we have devised a cost-benefit disease control model to simulate the effect of various control methods on disease incidence and the cost associated with each of the scenarios.

The prevalence of rabies cases in the territory of Azerbaijan, January 2015-June 2016

Rabies is an infectious disease which was and remains to be one of the most serious diseases of all species of hematothermal animals and humans, in many regions of the world. The epizootic situation on rabies in the Republic of Azerbaijan has been unfavorable for many years, which is confirmed by scientific data and the veterinary cases reporting in the EIDSS system. This system was introduced in the country in 2009 and is the electronic System of disease control.

The test-negative design for estimating influenza vaccination effectiveness

The test-negative design is a variation of the case-control study, in which patients are enrolled in outpatient clinics (and/or hospitals) based on a clinical case definition such as influenza-like illness (ILI). Patients are then tested for influenza virus, and VE is estimated from the odds ratio comparing the odds of vaccination among patients testing positive for influenza versus those testing negative, adjusting for potential confounding factors. The design leverages existing disease surveillance networks and as a result, studies using it are increasingly being reported.

Utility of Natural Language Processing for Clinical Quality Measures Reporting

Clinical quality measures (CQMs) are tools that help measure and track the quality of health care services. Measuring and reporting CQMs helps to ensure that our health care system is delivering effective, safe, efficient, patient-centered, equitable, and timely care. The CQM for influenza immunization measures the percentage of patients aged 6 months and older seen for a visit between October 1 and March 31 who received (or reports previous receipt of) an influenza immunization.

Post-vaccination rabies sero-survey in Georgia, 2015

Rabies is endemic in Georgia with up to 100 confirmed cases in animals per year. There is an estimated 350,000 domestic and stray dogs/cats in Georgia. The prophylactic vaccination of domestic animals against rabies was reestablished in Georgia in 2013. Each year since 2013, coverage has increased aiming to cover approximately 70% of the total population of dogs/cats in Georgia.


The objective of this survey was to study vaccination coverage and quality in dogs in Georgia through the detection of post-vaccination antibodies.
