A major goal of Natural Language Processing in the public health informatics domain is the automatic extraction and encoding of data stored in free text patient records. This extracted data can then be utilized by computerized systems to perform syndromic surveillance. In particular, the chief complaint--a short string that describes a patient's symptoms--has come to be a vital resource for syndromic surveillance in the North American context due to its near ubiquity. This paper reviews fifteen systems in North America--at the city, county, state and federal level--that use chief complaints for syndromic surveillance.

Entomological surveillance plays a crucial role in designing and implementing mosquito control measures. In this context, developing more effective collection strategies is essential to accurately estimate the entomological parameters necessary for effective control. In this study, we investigated the effectiveness of four traps: CDC light trap, MosqTent, BG-Sentinel, and SkeeterVac, compared to human landing catch (HLC) in the collection of Mansonia mosquitoes, known to cause discomfort to riverside populations along the Madeira River in the District of Jaci Paraná, Porto Velho, in Rondônia state, Brazil.

Antimicrobial resistance (AMR), arising from decades of imprudent anthropogenic use of antimicrobials in healthcare and agriculture, is considered one of the greatest One Health crises facing healthcare globally. Antimicrobial pollutants released from human-associated sources are intensifying resistance evolution in the environment. Due to various ecological factors, wildlife interact with these polluted ecosystems, acquiring resistant bacteria and genes.

Vector-borne diseases pose significant threats to both human and animal health, including wildlife, particularly in vulnerable island ecosystems like the Galapagos Islands. This study examines the mosquito community composition around domestic dogs and Galapagos sea lion rookeries across four islands: San Cristobal, Isabela, Santa Cruz, and Floreana. Using BG-Sentinel traps, a total of 292 mosquitoes were collected, identifying three species: Culex quinquefasciatus, Aedes aegypti, and A.

Background: Residents of facilities for older people are vulnerable to COVID-19 outbreaks. Nevertheless, timely recognition of outbreaks at facilities for older people at public health centers has been impossible in Japan since May 8, 2023, when the Japanese government discontinued aggressive countermeasures against COVID-19 because of the waning severity of the dominant Omicron strain. The Facility for Elderly Surveillance System (FESSy) has been developed to improve information collection.

Introduction: () is a common foodborne pathogen in coastal areas of China. Most epidemiological studies on have focused on foodborne disease outbreaks, with fewer studies based on long-term, continuous, and systematic sentinel surveillance.
Methods: Data were collected from the national foodborne disease active surveillance program in 31 provincial-level administrative divisions (PLADs) in China from 2013 to 2022.
