Although lead poisoning can cause detrimental health effects, it is largely preventable. Common exposure sources include contaminated soil, water, and lead-based paint in homes built before the 1978 ban on residential lead-containing paint. In North Carolina, testing for lead is encouraged for all children at ages 1 and 2 years, and is required for children covered by Medicaid. In October 2023, routine pediatric blood lead testing and follow-up investigations conducted by the North Carolina Department of Health and Human Services identified four asymptomatic cases of lead poisoning associated with consumption of cinnamon-containing applesauce packaged in pouches. The Food and Drug Administration (FDA) identified lead in the cinnamon as the source of contamination; chromium was later also detected in the cinnamon. FDA alerted the public on October 28, and the distributor initiated a voluntary recall the following day. To estimate the impact of the event and characterize reported cases, CDC initiated a national call for cases (defined as a blood lead level [BLL] ≥3.5 μg/dL in a person of any age in ≤3 months after consuming a recalled cinnamon-containing applesauce product). During November 22, 2023-April 12, 2024, a total of 44 U.S. states, the District of Columbia, and Puerto Rico reported 566 cases (55% in children aged <2 years, including 20% that were temporally associated with symptoms). The median maximum venous BLL was 7.2 μg/dL (range = 3.5-39.3 μg/dL). The hundreds of children poisoned by this incident highlight the importance of preventing toxic metal contamination of food and promoting routine childhood blood lead testing and follow-up to identify lead exposure sources. Clinicians and public health practitioners should be aware of the potential for exposure to toxic metals from less common sources, including food.

CONTEXT: Lead exposures among school-age children are a major public health issue. Although the harmful effects of lead exposure during the first years of life are well known, there is not as much understanding of the effects of low levels of lead exposure during later childhood. OBJECTIVES: To review the effects of blood lead levels (BLLs) <10 µg/dL in school-age children and adolescents. DATA SOURCES: We searched Medline, Embase, Global health, CINAHL, Scopus, and Environmental Science Collection databases between January 1, 2000, and May 11, 2023. STUDY SELECTION: We included peer-reviewed English-language articles that presented data on the effects of BLLs <10 µg/dL in individuals ages 5 through 18 years. DATA EXTRACTION: Data on country, population, analytic design, sample size, age, BLLs, outcomes, covariates, and results were extracted. RESULTS: Overall, 115 of 3180 screened articles met the inclusion criteria. The reported mean or median BLL was <5 µg/dL in 98 articles (85%). Of the included articles, 89 (77%) presented some evidence of an association between BLLs <10 µg/dL during school age and detrimental outcomes in a wide range of categories. The strongest evidence of an association was for the outcomes of intelligence quotient and attention-deficit/hyperactivity disorder diagnoses or behaviors. LIMITATIONS: Few articles controlled for BLLs at age <5 years, limiting conclusions about the relation between later BLLs and outcomes. CONCLUSIONS: BLLs <10 µg/dL in school-age children and adolescents may be associated with negative outcomes. This review highlights areas that could benefit from additional investigation.

By June 2020, Marshallese and Hispanic or Latino (Hispanic) persons in Benton and Washington counties of Arkansas had received a disproportionately high number of diagnoses of coronavirus disease 2019 (COVID-19). Despite representing approximately 19% of these counties' populations (1), Marshallese and Hispanic persons accounted for 64% of COVID-19 cases and 57% of COVID-19-associated deaths. Analyses of surveillance data, focus group discussions, and key-informant interviews were conducted to identify challenges and propose strategies for interrupting transmission of SARS-CoV-2, the virus that causes COVID-19. Challenges included limited native-language health messaging, high household occupancy, high employment rate in the poultry processing industry, mistrust of the medical system, and changing COVID-19 guidance. Reducing the COVID-19 incidence among communities that suffer disproportionately from COVID-19 requires strengthening the coordination of public health, health care, and community stakeholders to provide culturally and linguistically tailored public health education, community-based prevention activities, case management, care navigation, and service linkage.

BACKGROUND: Morgellons is a poorly characterized constellation of symptoms, with the primary manifestations involving the skin. We conducted an investigation of this unexplained dermopathy to characterize the clinical and epidemiologic features and explore potential etiologies. METHODS: A descriptive study was conducted among persons at least 13 years of age and enrolled in Kaiser Permanente Northern California (KPNC) during 2006-2008. A case was defined as the self-reported emergence of fibers or materials from the skin accompanied by skin lesions and/or disturbing skin sensations. We collected detailed epidemiologic data, performed clinical evaluations and geospatial analyses and analyzed materials collected from participants' skin. RESULTS: We identified 115 case-patients. The prevalence was 3.65 (95% CI = 2.98, 4.40) cases per 100,000 enrollees. There was no clustering of cases within the 13-county KPNC catchment area (p = .113). Case-patients had a median age of 52 years (range: 17-93) and were primarily female (77%) and Caucasian (77%). Multi-system complaints were common; 70% reported chronic fatigue and 54% rated their overall health as fair or poor with mean Physical Component Scores and Mental Component Scores of 36.63 (SD = 12.9) and 35.45 (SD = 12.89), respectively. Cognitive deficits were detected in 59% of case-patients and 63% had evidence of clinically significant somatic complaints; 50% had drugs detected in hair samples and 78% reported exposure to solvents. Solar elastosis was the most common histopathologic abnormality (51% of biopsies); skin lesions were most consistent with arthropod bites or chronic excoriations. No parasites or mycobacteria were detected. Most materials collected from participants’ skin were composed of cellulose, likely of cotton origin. | CONCLUSIONS: This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health-related quality of life. No common underlying medical condition or infectious source was identified, similar to more commonly recognized conditions such as delusional infestation.
