Rickettsia rickettsii subsp. californica subsp. nov., the etiologic agent of Pacific Coast tick fever.

The etiologic agent of Pacific Coast tick fever (PCTF), a moderately severe tickborne illness that resembles Rocky Mountain spotted fever (RMSF), was first isolated in 1966 from specimens of Dermacentor occidentalis (the Pacific Coast tick) obtained in California. For several decades, this bacterium was identified ambiguously as the unclassified spotted fever group Rickettsia species 364-D, Rickettsia 364, or Rickettsia philipii. However, none of these epithets satisfied criteria of formal bacterial nomenclature.

Medical Coders' Use of the ICD-10-CM "Unspecified" Codes for Head and Brain Injury in Emergency Department Settings.

Context: In the emergency department (ED) setting, prioritizing triage and patient care may lead to challenges in capturing detailed documentation necessary for specific International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) coding in medical records. Consequently, the prevalent use of the "unspecified head injury" code poses concerns about the precision of ED-based administrative billing claims data when analyzed for public health surveillance of nonfatal traumatic brain injuries (TBIs). Understanding the perspective of medical coders can illuminate coding processes and opportunities to enhance coding accuracy for TBI and other head injuries in the ED.

Summary of the Centers for Disease Control and Prevention's Self-reported Traumatic Brain Injury Survey Efforts.

Objective: Surveillance of traumatic brain injury (TBI), including concussion, in the United States has historically relied on healthcare administrative datasets, but these methods likely underestimate the true burden of TBI. The Centers for Disease Control and Prevention (CDC) has recently added TBI prevalence questions to several national surveys. The objective of this article is to summarize their recent efforts and report TBI prevalence estimates.

Strengthening Public Health Capacity to Address Infectious Diseases: Lessons From 3 Centers of Excellence in Public Health and Homelessness.

People experiencing homelessness are disproportionately affected by infectious diseases and often face barriers to receiving appropriate medical treatment. Responding to the needs of people experiencing homelessness requires state and local health departments to integrate information sources and coordinate multisector efforts. From 2021 to 2023, the CDC Foundation, in cooperation with the Centers for Disease Control and Prevention, established pilot Centers of Excellence in Public Health and Homelessness in Seattle, Washington; San Francisco, California; and the state of Minnesota.

Developing and Implementing In-Person and Virtual SoilSHOPs in Atlanta, Georgia, as a Community-Engaged Approach to Screen and Prevent Soil Lead Exposure.

Urban agriculture presents the opportunity for increased availability of local, fresh foods; however, exposure to lead soil contamination can occur through gardening in urban environments. Through a community-engaged partnership, we implemented Soil Screening, Health, Outreach and Partnerships (soilSHOPs), in-person and virtually, to screen soils for lead in Atlanta, Georgia. These soilSHOPs inform best practices for increasing awareness about lead exposure and grounding interventions in residents' lived experiences and also led the US Environmental Protection Agency to identify a Superfund site.

Increases In COVID-19 Vaccination Among NYC Municipal Employees After Implementation Of Vaccination Requirements.

In July 2021 New York City (NYC) instituted a requirement for all municipal employees to be vaccinated against COVID-19 or undergo weekly testing. The city eliminated the testing option November 1 of that year. We used general linear regression to compare changes in weekly primary vaccination series completion among NYC municipal employees ages 18-64 living in the city and a comparison group of all other NYC residents in this age group during May-December 2021.
