Shiga toxin-producing Escherichia coli (STEC) causes an estimated 265 000 infections in the United States annually. Of emerging non-O157:H7 STEC serotypes, O26 is the most commonly recognized. During an outbreak of STEC O26 in Oregon in 2015, we used syndromic surveillance data to supplement case finding by laboratory reporting. From 157 records retrieved by querying syndromic surveillance data, we detected 4 confirmed and 5 suspected cases. However, none of the suspected cases were confirmed by stool culture, and by the time that the data were being analyzed, the confirmed cases were already known to investigators. Syndromic surveillance data can potentially supplement case finding during outbreaks of foodborne disease. To be an effective case-finding strategy, timely completion of all steps, including collecting specimens from suspected cases, should be performed in real time.

Developing Countries Vaccine Manufacturers Network (DCVMN) is an alliance of vaccine developers, manufacturers, and marketing authorization holders (MAHs) from low- and middle-income countries (LMICs) that plays a vital role in ensuring equitable, inclusive, accountable, and timely access to affordable, high-quality vaccines in these countries. Besides research and development, this network promotes manufacturing and global supply chains for effective strengthening of regulatory and pharmacovigilance activities. Traditionally, vaccine safety surveillance systems in LMICs rely on spontaneous reporting.

Department of Family Medicine, McMaster University, Hamilton, Ontario, Canada.
Background: There is an increasing prevalence of multiple conditions (multimorbidity) and multiple medications (polypharmacy) across many populations. Previous literature has focused on the prevalence and impact of these health states separately, but there is a need to better understand their co-occurrence.
Methods And Findings: This study reported on multimorbidity and polypharmacy among middle-aged and older adults in two national datasets: the Canadian Longitudinal Study on Aging (CLSA) and the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).

National Center for Birth Defects Monitoring, West China Second University Hospital, Sichuan University, Chengdu, China.
Background: The landscape of co-occurring birth defects among infants with congenital diaphragmatic hernia (CDH) remains underexplored.
Aims: This study aims to elucidate the complex patterns of co-occurring defects in Chinese population.
Materials And Methods: We analyzed cases from the Chinese Birth Defects Monitoring Network (2007-2019) with CDH that presented along with at least one additional defect but without a syndromic diagnosis.

Background: This study investigates the prevalence and intensity of parasitic infections in animal fecal samples collected from Sitio Ibayo, San Mateo, Rizal, Philippines, a suburban community considered a potential sentinel site for zoonotic disease surveillance.
Methods: Using cross-sectional sampling, 132 animal fecal samples were collected in the area exhaustively. Samples were processed through direct smear with saline solution and Lugol's iodine and flotation technique using mini- and fill-FLOTAC.
