Field investigation of high reported non-neonatal tetanus burden in Uganda, 2016-2017.

Background: Despite providing tetanus-toxoid-containing vaccine (TTCV) to infants and reproductive-age women, Uganda reports one of the highest incidences of non-neonatal tetanus (non-NT). Prompted by unusual epidemiologic trends among reported non-NT cases, we conducted a retrospective record review to see whether these data reflected true disease burden.

Methods: We analysed nationally reported non-NT cases during 2012-2017.

Shigellosis Cases With Bacterial Sexually Transmitted Infections: Population-Based Data From 6 US Jurisdictions, 2007 to 2016.

Background: Shigella species, which cause acute diarrheal disease, are transmitted via fecal-oral and sexual contact. To better understand the overlapping populations affected by Shigella infections and sexually transmitted infections (STIs) in the United States, we examined the occurrence of reported STIs within 24 months among shigellosis case-patients.

Methods: Culture-confirmed Shigella cases diagnosed from 2007 to 2016 among residents of 6 US jurisdictions were matched to reports of STIs (chlamydia, gonorrhea, and all stages of syphilis) diagnosed 12 months before or after the shigellosis case.

Risk of Human Immunodeficiency Virus Acquisition Among High-Risk Heterosexuals With Nonviral Sexually Transmitted Infections: A Systematic Review and Meta-Analysis.

Background: Nonviral sexually transmitted infections (STIs) increase risk of sexually acquired human immunodeficiency virus (HIV) infection. Updated risk estimates carefully scrutinizing temporality bias of studies are needed.

Methods: We conducted a systematic review (PROSPERO CRD42018084299) of peer-reviewed studies evaluating variation in risk of HIV infection among high-risk heterosexuals diagnosed with any of: Chlamydia trachomatis, Mycoplasma genitalium, Neisseria gonorrhoeae, Treponema pallidum, and/or Trichomonas vaginalis.

Response to a Large HIV Outbreak, Cabell County, West Virginia, 2018-2019.

Introduction: In January 2019, the West Virginia Bureau for Public Health detected increased HIV diagnoses among people who inject drugs in Cabell County. Responding to HIV clusters and outbreaks is 1 of the 4 pillars of the Ending the HIV Epidemic in the U.S.

Enhancing U.S. Local, State, and Federal Preparedness Through Simulated Interactive Tabletop Exercises of a Mock Antibiotic-Resistant Gonorrhea Outbreak, 2018-2019.

Background: Responding effectively to outbreaks of antibiotic-resistant gonorrhea (ARGC) in the future will likely prove challenging. Tabletop exercises (TTXs) may assist local, state, and federal public health officials evaluate existing ARGC outbreak response plans, strengthen preparedness and response effectiveness, and identify critical gaps to address before an outbreak.

Methods: In 2018 to 2019, Centers for Disease Control and Prevention (CDC) collaborated with state partners to develop and implement TTXs to simulate a public health emergency involving an ARGC outbreak.

Risk of HIV Acquisition Among Men Who Have Sex With Men Infected With Bacterial Sexually Transmitted Infections: A Systematic Review and Meta-Analysis.

Background: Men who have sex with men (MSM) who have bacterial sexually transmitted infections (STIs) are at increased risk for HIV infection. We enhanced and updated past summary risk estimates.

Methods: We systematically reviewed (PROSPERO No.

Urine Bisphenol A and Arsenic Levels in Residents of the Cheyenne River Sioux Tribe, South Dakota, with and without Diabetes.

Introduction: Diabetes disproportionately affects American Indians/Alaskan Natives (AI/AN). Bisphenol A (BPA) and arsenic (As), environmental toxicants which may be associated with diabetes, have not been well studied in this population. Our objectives were to determine if urinary BPA and As are associated with diabetes among adults in the Cheyenne River Sioux Tribe (CRST), and to compare their urinary levels with the general US population.

Severe illness associated with reported use of synthetic cannabinoids: a public health investigation (Mississippi, 2015).

Study Objectives: In April 2015, a multistate outbreak of illness linked to synthetic cannabinoid (SC) use was unprecedented in magnitude and severity. We identified Mississippi cases in near-real time, collected information on cases to characterize the outbreak, and identified the causative SC.

Methods: A case was defined as any patient of a Mississippi healthcare facility who was suspected of SC use and presenting with ≥2 of the following symptoms: sweating, severe agitation, or psychosis during April 2-May 3, 2015.

Progress towards achieving and maintaining maternal and neonatal tetanus elimination in the African region.

Despite the availability of effective tetanus prevention strategies, as of 2016, Maternal and Neonatal Tetanus Elimination (MNTE) has not yet been achieved in 18 countries globally. In this paper, we review the status of MNTE in the World Health Organization African Region (AFR),and provide recommendations for achieving and maintaining MNTE in AFR. As of November 2016, 37 (79%) AFR countries have achieved MNTE, with 10 (21%) countries remaining.

Hepatitis A Cases Among Food Handlers: A Local Health Department Response-New York City, 2013.

During 2013, the New York City Department of Health and Mental Hygiene (DOHMH) received reports of 6 hepatitis A cases among food handlers. We describe our decision-making process for public notification, type of postexposure prophylaxis (PEP) offered, and lessons learned. For 3 cases, public notification was issued and DOHMH offered only hepatitis A vaccine as PEP.

Multistate US Outbreak of Rapidly Growing Mycobacterial Infections Associated with Medical Tourism to the Dominican Republic, 2013-2014(1).

During 2013, the Maryland Department of Health and Mental Hygiene in Baltimore, MD, USA, received report of 2 Maryland residents whose surgical sites were infected with rapidly growing mycobacteria after cosmetic procedures at a clinic (clinic A) in the Dominican Republic. A multistate investigation was initiated; a probable case was defined as a surgical site infection unresponsive to therapy in a patient who had undergone cosmetic surgery in the Dominican Republic. We identified 21 case-patients in 6 states who had surgery in 1 of 5 Dominican Republic clinics; 13 (62%) had surgery at clinic A.

Medical Toxicology and Public Health-Update on Research and Activities at the Centers for Disease Control and Prevention and the Agency for Toxic Substances and Disease Registry : Environmental Exposures among Arctic Populations: The Maternal Organics Monitoring Study in Alaska.

Evidence suggests that in-utero exposure to environmental chemicals, such as persistent organic pollutants (POPs), heavy metals, and radionuclides, that might bioaccumulate in the mother may increase a newborn's risk of adverse developmental, neurological, and immunologic effects. Chemical contamination of bodies of water and strong ocean currents worldwide can drive these chemicals from lower latitudes to Arctic waters where they accumulate in common traditional subsistence foods. In response to concerns of the people from Alaska of the effects of bio-accumulated chemicals on their children, the Maternal Organics Monitoring Study(MOMS) was developed.

Description of calls from private well owners to a national well water hotline, 2013.

Water Systems Council (WSC) is a national, non-profit organization providing education and resources to private household well owners. Since 2003, WSC has provided wellcare®, a toll-free telephone hotline to answer questions from the public regarding well stewardship. In order to identify knowledge gaps regarding well stewardship among private well owners, we obtained data from WSC and reviewed calls made during 2013 to wellcare®.
