Epidemiological Distribution of Reported West Nile cases in Houston, Texas, 2014-2017

West Nile virus (WNV) is considered the leading cause of domestically acquired arboviral disease and is spread through mosquitoes. In general, the majority of the cases are asymptomatic. One in five people infected will display mild symptoms like fever, headache, body ache, nausea, and vomiting. Only about 1 in 150 people infected will develop serious neurologic complications such as encephalitis and meningitis. According to CDC, in 2017, there were 133 confirmed cases including 5 deaths and 14 presumptive blood donors reported in the State of Texas.

Retrospective Surveillance of Perinatal Hepatitis C Virus Exposure – Tennessee, 2013-2017

Hepatitis C virus (HCV) infections are increasing nationwide and are of particular concern in Tennessee, especially among individuals of reproductive age.1,2 Maternal HCV status reported on the birth certificate reveals that the rate of HCV among women giving birth in TN increased 163% from 2009-2014.3 Further, a 2017 TN Department of Health (TDH) study found that 30% of reproductive aged women with newly reported chronic HCV in TN were determined to be pregnant.

Epidemiological trends of Reported Legionnaires disease in Houston, Texas, 2014-2017

Legionellosis is a respiratory illness that is mostly (80-90%) caused by the bacterium Legionella pneumophila. It is associated with a mild febrile illness, Pontiac fever, or Legionnaires'™ disease (1), a source of severe, community-acquired pneumonia. Legionella bacteria mostly affect elderly persons specifically those with underlying debilitating illnesses and with lowered immune systems.

Seroprevalence and factors associated with seropositivity to Rift Valley fever virus in livestock

Rift Valley fever (RVF) is a mosquito-borne viral zoonosis. This study aimed to estimate the prevalence of antibodies to RVF virus (RVFV) in cattle, sheep, and goats in South Africa, near the 2010-2011 outbreak epicenter and identify factors associated with seropositivity.

Objective: The objective of this study was to estimate the prevalence of antibodies to RVFV in domestic cattle, sheep, and goats in a study area in the central interior of South Africa, and to identify factors associated with seropositivity.

Epidemiology of SFTSV in Ticks collected from National Park in the ROK, 2015-2018

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging viral disease in East-Asian countries, including China, Japan, and the Republic of Korea (ROK). The causative agent of SFTS is the SFTS virus (SFTSV) transmitted by hematophagous ticks.

Objective: To survey the distribution of Ixodid tick and infection of severe fever with thrombocytopenia syndrome virus (SFTSV) in natural environments from Deogyusan national parks in Korea.

Surveillance for Lyme disease in Canada: 2009-2015

Lyme disease (LD), a multisystem infection that is manifested by progressive stages (1), is emerging in central and eastern provinces of Canada due to northward expansion of the geographic range of Ixodes scapularis, the main vector in these regions (2). In 2004, approximately 40 human cases of LD were reported in Canada. In 2009, LD disease became nationally notifiable, with provincial and territorial health departments reporting clinician-diagnosed cases to the Public Health Agency of Canada (PHAC).

Factors Predicting Retention In Care and Health Outcomes Among HIV Patients

The prevalence of persons living and diagnosed with HIV infection in the United States in 2010 to 2014 increased in number and rate (Center for Disease Control & Prevention (CDC), 2016). In 2015, persons aged 25-29 years had the highest rate (33.4), followed by persons aged 20-24 years (31.2) (CDC, 2016). Consistent reduced viral load is associated with reduced morbidity and mortality and a lower likelihood of transmitting HIV to sex partners (CDC, 2011). Retention into HIV care promotes life and decreases the risk for HIV transmission (Yehia et. al. 2015).

Surveillance of Respiratory Viruses in Long Term Care Facilities

Although residents of LTCFs have high morbidity and mortality associated with ARIs, there is very limited information on the virology of ARI in LTCFs.[1,2] Moreover, most virological testing of LCTF residents is reactive and is triggered by a resident meeting selected surveillance criteria. We report on incidental findings from a prospective trial of introducing rapid influenza diagnostic testing (RIDT) in ten Wisconsin LTCFs over a two-year period with an approach of testing any resident with ARI.

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.
