Article Synopsis
- Climate change and extreme weather events are suspected to increase the spread of Campylobacter, a major cause of bacterial gastroenteritis, but the specific effects on these infections have not been thoroughly studied.
- The literature review analyzed peer-reviewed articles published until September 2022, focusing on how various weather factors (like precipitation, temperature, and humidity) influence Campylobacter infections in humans, ultimately synthesizing findings from 47 relevant studies.
- Results indicate that higher precipitation and temperature correlate with increased infections, while low humidity and sunshine have the opposite effect; however, many studies didn't fully consider other influencing factors such as seasonality and animal operations.
Background: American Indian and Alaska Native (AIAN) populations are frequently associated with the highest rates of tuberculosis (TB) disease of any racial/ethnic group in the USA. We systematically investigated variation in patterns and potential drivers of TB epidemiology among geographically distinct AIAN subgroups.
Methods: Using data reported to the National Tuberculosis Surveillance System during 2010-2020, we applied a geographic method of data disaggregation to compare annual TB incidence and the frequency of TB patient characteristics among AIAN persons in Alaska with AIAN persons in other states.
Objective: and are common causes of reported foodborne illness. On August 6, 2021, the Alaska Division of Public Health identified a multipathogen gastrointestinal outbreak among hospital staff in Homer, Alaska. The objectives of this study were to identify the outbreak source and prevent future illness.

Although trichinellosis in the United States has historically been associated with consumption of pork, multiple nonporcine species of wild game also are competent hosts for Trichinella spp. and have been collectively implicated in the majority of trichinellosis cases since the late 1990s (1-4) (Figure 1).
