Accuracy of ICD Codes for Identification: Review of Chlamydia, Gonorrhea and Syphilis

Administrative data refers to data generated during the processes of health care. These data are a rich source of patient health information, including diagnoses and problem lists, laboratory and diagnostic tests, and medications. Established standards are used to code each data into the appropriate coding systems.

Field-based Evaluation of Malaria Outbreak Detection & Response, Mudzi and Goromonzi

Infectious disease outbreaks, such as the Ebola outbreak in West Africa, highlight the need for surveillance systems to quickly detect outbreaks and provide data to prevent future pandemics. The World Health Organization (WHO) developed the Joint External Evaluation (JEE) tool to conduct country-level assessments of surveillance capacity. However, considering that outbreaks begin and are first detected at the local level, national-level evaluations may fail to identify capacity improvements for outbreak detection.

Surveillance on Arboviral Infections in Georgia by using One Health Approach

Arbovirus infections are causing enormous global burden, while their geographic distribution expands and affects new regions and areas. West Nile virus (WNV), one of the most important pathogens among arboviruses, was historically associated with causing mild febrile illness, however, after the outbreak occurred in the North America, which caused more severe illness, it has received wider recognition.

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.

Flexibility of ED surveillance system to monitor dengue outbreak in Reunion Island

In Reunion Island, a French overseas territory located in the southwestern of Indian Ocean, the dengue virus circulation is sporadic. Since 2004, between 10 and 221 probable and confirmed autochthonous dengue fever cases have been reported annually. Since January 2018, the island has experienced a large epidemic of DENV serotype 2. As of 4 September 2018, 6,538 confirmed and probable autochthonous cases have been notified1.

Time Series Analysis of Infectious Disease Mortality in Ukraine (1965-2015)

Monitoring of long-term infectious disease mortality trends is of great value to national public health systems both in estimation of the efficacy of preventive programs, and in development of the new strategies of preventive measures. In the developed countries, there are a number of studies with long-term time series of infectious disease mortality analysis in epidemiological and historical aspects. Our research was based on the work by Armstrong GL, Conn LA and Pinner RW, 1999. Literature review revealed that such analysis has been never carried out in Ukraine up to now.

Acute Hepatitis A Infections among Veterans in Outbreak States, 2016-2018

Although cases of acute HAV have declined in recent years, elevated numbers of HAV infections began to be reported by California and Michigan in the fall of 2016.1,2 Since this time, associated outbreaks have been reported in 9 additional states (Arizona, Utah, Kentucky, Missouri, Tennessee, Indiana, Ohio, Arkansas, and West Virginia).3 No common source of food, beverages or drugs have been identified and transmission appears to be primarily person-to-person with high-risk individuals including people experiencing homelessness, those who use illicit drugs and their close direct contacts.

Hepatitis C testing trends among large commercially insured populations, 2011-2017

Hepatitis C virus (HCV) infection is the most common blood-borne infection in the US, and a leading cause of liver-related morbidity and mortality. Approximately 3.5 million individuals in the US were estimated to have been living with hepatitis C in 2010, and approximately half of them were unaware that they were infected. Among HCV infected individuals, those born between 1945 and 1965 (usually referred to as the baby boomer cohort) represent approximately 75% of current cases.

Timely Public Health Intervention and Vectorborne Response Planning

The OKC-Co Health Department deployed a phased vectorborne response plan to address multiple diseases, including Zika Virus and West Nile Virus. This plan is scalable and flexible, but must necessarily prepare for the worst case scenario. Although not currently a local threat in OKC-Co, Zika virus response planning requires early coordination between state, local and federal agencies in order to mitigate risk to the population.

Analysis of Three CRISPR Loci Among Yersinia pestis Stains from Georgia and Neighboring Countries

Particular family of tandem repeats, such as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) found in a wide range of prokaryotic genomes. CRISPRs consist of highly conserved repeats interspaced with non-repetitive elements or "spacers" usually of viral origin. In the Yersinia pestis genome, three CRISPR elements YPa, YPb and YPc are found. The distribution of spacers and their arrays in Y. pestis strains is region and focus specific and can provide important information for genotyping and evolutionary research of bacteria.
