The webinars and online classes listed here are shared solely as opportunities to learn more information of interest to public health personnel. All times listed are in Central Time.

July 7, 2026; 12–1 p.m. What’s Working Right Now: Low-Cost Tools from Local Health Departments.
Join NACCHO’s webinar series to hear directly from local health departments sharing practical, budget-friendly approaches to tackling real-world public health challenges. This webinar will cover two tools. Tool 1: Bend It Like REDCap: Leveraging REDCap to Build End-to-End Project Management Systems by Jennifer Lowe, Johnson County Department of Health and Environment. Public health agencies are increasingly looking for low-cost tools to streamline operations and track program performance. In this webinar, the Johnson County Department of Health and Environment will share how they expanded REDCap beyond surveys to serve as a centralized system for project management and performance tracking. Learn how this internally hosted, no-cost solution is used to monitor requests, timelines, and key performance indicators across multiple programs and how similar approaches can support operational efficiency and reporting in your organization. Tool 2: Mapmaking in R by Katherine Hathaway, San Antonio Metropolitan Health District (Metro Health). Many local health departments lack the resources to invest in costly GIS software, creating barriers to mapping and spatial analysis. In this webinar, participants will explore an open-source alternative using R, including packages like tidycensus and other tidyverse tools, to create meaningful public health maps. The session will also compare these approaches to traditional GIS solutions, highlighting both the cost-saving benefits and the level of technical expertise required, offering practical insights for agencies considering open-source mapping options.

Bustrak S, Rodriguez JD, Yeung LF, et al. Availability of folic acid fortified corn masa products in selected areas in the United States. Birth Defects Res. 2026;118(6):e70084. doi:10.1002/bdr2.70084
Abstract
Objective: To assess the availability of folic acid fortified corn masa (CM) products across selected areas/regions in the United States for neural tube defects (NTD) prevention 8 years after voluntary fortification of CM products was permitted.
Methods: Geographic selection using US census data included areas with majority Hispanic census tracts in California (CA), Georgia, and Texas (TX). A largely rural county in CA, an urban county in TX, and the metropolitan Atlanta area were selected as study sites. Stores selling groceries and snacks in the selected areas were visited and surveyed for CM products. A mobile application was used to record product data, including product identifiers (e.g., brand name, product type) and folic acid information (e.g., presence and amount of folic acid, folic acid graphical design element). Analyses were performed using R studio.
Results: In the 111 stores surveyed, products identified included 50 distinct retail CM flour bags, 178 distinct corn tortilla products, 88 distinct tostada products, and 223 other distinct CM products. Fifty percent of distinct CM flour bags (25/50) were fortified with folic acid. Additionally, 1% (2/178) of tortillas and about 3% (3/88) of tostadas were fortified. No other fortified products were identified.
Conclusion: Almost a decade after voluntary folic acid fortification of CM flour was allowed, very few ready-made CM products assessed in this study were fortified. As states work to initiate changes to increase the availability of fortified products, continued assessment can help monitor the availability of fortified products for NTD prevention.

Crisp CA, Milton S, Lutz CS, et al. Notes from the field: Initial public health response to a measles outbreak in a close-knit West Texas community - January-February 2025. MMWR Morb Mortal Wkly Rep. 2026;75(23):300-302. Published 2026 Jun 18. doi:10.15585/mmwr.mm7523a2
Summary
What is already known about this topic? Measles is a highly contagious respiratory virus that can cause serious illness. A measles outbreak occurred in Texas during January–August 2025.
What is added by this report? During January 29–February 28, 2025, Texas reported 207 confirmed measles cases, primarily among members of a close-knit west Texas community. Most cases occurred among unvaccinated persons or those with unknown vaccination status. Measles, mumps, and rubella (MMR) vaccine and measles testing clinics were offered; however, community members were hesitant to interact with public health and health care systems, and MMR vaccine acceptance was low. Educational materials on measles and measles prevention were developed and distributed.
What are the implications for public health practice? In challenging community contexts, public health messaging intended to limit viral transmission and severe health outcomes could supplement standard control measures, including advising persons with suspected measles to avoid contact with other persons to prevent transmission and to seek medical care promptly.

Haas CB, Shiels MS, Luo Q, et al. Markers of immune function and survival among cancer patients with HIV in the United States: a population-based registry linkage study. Clin Infect Dis. Published online May 29, 2026. doi:10.1093/cid/ciag333
Abstract
Background: People with HIV (PWH) and cancer have greater cancer-specific mortality than patients without HIV, which may reflect effects of immunosuppression. We aimed to describe the associations between low CD4 cell counts and cancer-specific mortality in PWH with cancer.
Methods: We used linked data from HIV and cancer registries to study 12 common cancers in PWH in 14 registries in the United States and Puerto Rico in 2008-2019. We used Cox regression to estimate hazard ratios (HRs) for the association of CD4 counts measured after cancer diagnosis (0-49, 50-99, 100-199, and 200+ CD4 cells/mm3) with cancer-specific mortality, adjusted for demographic and cancer-related factors. We estimated 3-year cancer-specific cumulative mortality using Fine-Gray models.
Results: We evaluated 12,087 PWH and cancer (the most common being non-Hodgkin lymphoma [NHL, N=2311], prostate cancer [N=1681], and Kaposi sarcoma [KS, N=1423]). Cancer-specific mortality was significantly greater for individuals with a CD4 count of 0-49 compared to 200+ cells/mm3 for NHL (HR=1.82, 95%CI=1.30-2.53), prostate cancer (HR=3.98, 95%CI=1.56-10.15), KS (HR=4.16, 95%CI=1.49-11.67), lung cancer (HR=1.69, 95%CI=1.33-2.14), colorectal cancer (HR=2.79, 95%CI=1.58-4.92), and liver cancer (HR=1.44, 95%CI=1.01-2.70). For lung cancer, those with a CD4 count of 200+ cells/mm3 had 3-year cancer-specific cumulative mortality of 52% versus 72% for those with a CD4 count of 0-49.
Conclusion: Among PWH with cancer, cancer-specific mortality increased with lower CD4 counts, including for solid tumors not associated with HIV, e.g., prostate and lung cancer. These results highlight the role of immunity in control of cancer.

Maclin BJ, Pfeiffer RM, Luo Q, et al. Sex differences in cancer incidence among people with HIV infection in the United States. J Natl Cancer Inst. Published online June 12, 2026. doi:10.1093/jnci/djag185
Abstract
Objective: Males have a higher incidence of most non-reproductive cancers than females, which has often been attributed to differences in lifestyle or behaviors. We examined whether sex differences in cancer incidence are attenuated among immunocompromised adults.
Methods: Using data from population-based linkage study of HIV and cancer registries (2001-2019), we estimated male-to-female incidence rate ratios (M:F IRRs) among people with HIV (PWH) for 20 cancer sites. We used Poisson regression to adjust for age, race/ethnicity, calendar year, HIV transmission category, and HIV diagnosis year. We compared the M:F IRRs among PWH (M:F IRRPWH) to M:F IRRs in the general population (M:F IRRGP) with a chi-square test.
Results: PWH contributed 3,956,838 person-years of follow-up (53.6% among males, 46.4% among females). The M:F IRRPWH was significantly attenuated compared to the M:F IRRGP for 9 cancer sites: tongue (M:F IRRPWH 1.39 vs. M:F IRRGP 2.94; P<0.0001), oropharynx (1.80 vs 4.74; P<0.0001), esophagus (1.36 vs 3.43; P<0.0001), colon (0.90 vs 1.19; P=0.0002), liver (2.20 vs 4.22; P < 0.0001), larynx (1.50 vs 4.32; P<0.0001), lung (0.92 vs 1.39; P < 0.0001), bladder (1.21 vs 3.02; P<0.0001), and diffuse large B-cell lymphoma (1.35 vs 1.65; P<0.0001). Hodgkin lymphoma was the only site where the M:F IRRPWH was significantly larger than the M:F IRRGP (1.96 vs 1.45; P=0.0001).
Conclusions: Although the incidence of most cancers remained higher among male than female PWH, the sex difference was attenuated among PWH for 9 cancers, suggesting that important immune differences between males and females in the general population contribute to differences in cancer incidence.

McGee-Avila JK, Haas CB, Shing JZ, et al. Hepatocellular carcinoma survival in people with and without HIV in the United States, 2001-2019. Clin Infect Dis. Published online April 9, 2026. doi:10.1093/cid/ciag137
Abstract
Background: Hepatocellular carcinoma (HCC) risk is elevated among people with human immunodeficiency virus (HIV) (PWH), but survival disparities are poorly understood.
Methods: We used data from the HIV/AIDS Cancer Match Study, a U.S. population-based linkage of 12 HIV and cancer registries during 2001-2019. Multivariable-adjusted Cox regression was used to estimate adjusted hazard ratios (aHRs) for HIV and HCC-specific and all-cause mortality among people with HCC, and to estimate aHRs for factors associated with HCC-specific and all-cause mortality among PWH.
Results: A total of 71 516 cases of HCC including 1610 PWH occurred during 2001-2019. Compared to people with HCC without HIV, a higher proportion of PWH were men, younger at time of cancer diagnosis, and were Black or Hispanic. Overall, 1279 deaths occurred among PWH (62.5% of deaths from HCC). HIV was associated with 34% higher all-cause mortality (aHR 1.34; 95% confidence interval, 1.27-1.41), and slightly increased HCC-specific mortality (aHR 1.08; 95% confidence interval, 1.01-1.16). Male sex, older age at HCC diagnosis, and nonreceipt of cancer treatment modalities were associated with increased all-cause and HCC-specific mortality among PWH. Increased HCC-specific mortality was also observed among men who have sex with men, compared to people who inject drugs. All-cause and HCC-specific mortality declined across calendar periods from 2001-2003 to 2016-2019 (Ptrends & .0002 and .06, respectively).
Conclusions: HIV is associated with 34% higher all-cause and 8% higher HCC-specific mortality among PWH with HCC compared to those without HIV. As PWH are now living longer, and are at higher risk of HCC, research should prioritize opportunities for HCC prevention, screening, diagnosis, and treatment.

Ovuegbe S, Collier A, Forrest D, McKieran L, Tsai J. Access to care during COVID-19: A qualitative study of healthcare system resilience in San Antonio, Texas. J Public Health Res. 2026;15(2):22799036261441334. Published 2026 Apr 14. doi:10.1177/22799036261441334
Abstract
Background: The COVID-19 pandemic challenged healthcare systems across the United States. It had distinct effects in rapidly growing cities like San Antonio, Texas. San Antonio, one of the fastest-expanding metropolitan areas, faces high rates of uninsured residents and a mix of urban and semi-rural healthcare landscapes. This makes it a valuable case for understanding health system responses to access challenges during public health crises. This qualitative study examined how healthcare system leaders, frontline providers, and policymakers in San Antonio navigated three major challenges during COVID-19: system-level disruptions in healthcare delivery, telehealth access, and health insurance coverage.
Methods: From February to April 2023, data came from 2 focus groups (n = 20) and 12 key informant interviews. These were analyzed thematically using a grounded theory approach to identify barriers and evidence-based resolutions.
Results: Participants identified three core challenges: First, disruptions in healthcare delivery due to workforce shortages, reduced preventive care access, and discharge delays. Second, barriers to telehealth access related to the digital divide and health literacy. Third, instability in health insurance coverage following the rollback of pandemic-era Medicaid protections. Participants also shared practice-based recommendations. These included standardized screening for social determinants of health (SDOH) with linked referrals to resources, culturally responsive food assistance programs, and hybrid care models that integrate telehealth with in-person care.
Conclusion: This project shows that engaging local leadership and coordinating strategies can make systems more resilient. These actions improve healthcare access during public health crises and offer practical lessons for other urban healthcare systems.

Sheriff FR, Benjamin RH, Xiao Q, et al. Neighbourhood social vulnerability and preterm birth risk among infants with trisomy 21: a statewide analysis. Paediatr Perinat Epidemiol. Published online April 24, 2026. doi:10.1111/ppe.70143
Abstract
Background: Residing in socioeconomically vulnerable areas is known to be associated with increased preterm birth (PTB) risk in the general population. However, the relationship between social vulnerability and PTB remains unexplored among infants with trisomy 21, who experience more than twice the PTB rate of the general population.
Objectives: The primary objective was to examine the association between maternal socioeconomic vulnerability, as measured by the SVI, and PTB among infants with trisomy 21.
Methods: We conducted a retrospective cohort study among infants with trisomy 21 born in Texas (1999-2018). We examined the association between neighbourhood vulnerability, measured by Social Vulnerability Index (SVI) quartiles, and PTB utilising data from the Texas Birth Defects Registry. Using Poisson regression, we estimated crude and adjusted risk ratios (RRs) and 95% confidence intervals (CIs), accounting for maternal demographic characteristics and health factors.
Results: Of the 8823 eligible infants included in the analysis, 2269 (25.7%) were born preterm. Maternal residence in the highest vulnerability quartile was associated with an increased risk of PTB (RR 1.17, 95% CI 1.04, 1.32) and moderate to late PTB (RR 1.19, 95% CI 1.05, 1.35), compared to the least vulnerable quartile. In secondary analyses stratified by race/ethnicity, the association with high vulnerability was particularly strong among non-Hispanic Black women (RR 1.44, 95% CI 1.00, 2.07).
Conclusions: These findings underscore the importance of neighbourhood social vulnerability in influencing perinatal health risks, particularly PTB among infants with trisomy 21.

Wolters R, Tark JY, Chambers TM, et al. Increased risk of sarcomas in children with congenital anomalies: findings from the genetic overlap between anomalies and cancer in kids (GOBACK) registry linkage study. Pediatr Blood Cancer. Published online May 22, 2026. doi:10.1002/1545-5017.70415
Abstract
Background: Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated.
Procedure: We obtained data on maternal and perinatal characteristics, congenital anomalies, and pediatric sarcoma diagnoses for all live births in nine states. We used Cox proportional hazards regression to estimate the hazard ratio (HR) and 95% confidence interval (CI) of sarcoma (overall and by subtype) among children with non-syndromic congenital anomalies. We considered all non-syndromic anomalies collectively, and when sample size allowed, we also evaluated specific anomaly-sarcoma associations.
Results: We evaluated 21,933,884 children, including 641,770 (2.9%) with major non-syndromic congenital anomalies. Compared to children without a congenital anomaly, children with a non-syndromic anomaly had a two-fold higher hazard for any soft tissue sarcoma (95% CI: 1.7-2.5), including rhabdomyosarcoma (HR 2.2, 95% CI: 1.7-3.0) and embryonal rhabdomyosarcoma (HR 2.5, 95% CI: 1.8-3.6), as well as non-rhabdomyosarcoma soft tissue sarcoma (HR 1.8, 95% CI: 1.3-2.5). The hazard of embryonal rhabdomyosarcoma was markedly increased in children with central nervous system anomalies (HR 7.9, 95% CI: 3.9-15.9), obstructive genitourinary defects (HR 4.6, 95% CI: 2.2-9.7), and limb reduction deformities (HR 3.8, 95% CI: 1.6-9.3).
Conclusions: Children with non-syndromic congenital anomalies are at increased risk of sarcomas, especially soft tissue sarcomas. Future studies should clarify shared developmental pathways and evaluate implications for sarcoma risk prediction and surveillance.

Carreño A, Aguilera MP, Ibañez L, et al. Analysis of prevalence and mortality among neonates and children with intestinal atresia: a multinational study, 1974-2015. Birth Defects Res. 2026;118(4):e70032. doi:10.1002/bdr2.70032
Abstract
Introduction: Small intestinal atresia (SIA) consists of a congenital obstruction of the lumen of the duodenum, jejunum, or ileum with varying severity. The aim of the investigation was to analyze the prevalence and mortality of SIA, using data from the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR).
Methods: Data on SIA cases were collected from 25 ICBDSR members' surveillance programs in 17 countries over 1974-2015. All pregnancy outcomes were included, but terminations of pregnancy were not available for 11 programs. Statistical analysis is descriptive, and the prevalence is established by the total of SIA cases divided by the total of births. The survival time was calculated, and mortality was analyzed individually using the Kaplan-Meier method for comparison.
Results: The total prevalence of SIA was 2.1 per 10,000 births. Iran had the highest prevalence with 11.5 per 10,000 total births (95% CI: 9-14.1); on the other hand, the lowest prevalence of SIA was in Mexico-Nuevo Leon with 0.5 per 10,000 births (95% CI: 0.3-0.8), and Cali-Colombia had zero cases. In South America, a higher prevalence of SIA was estimated compared to what was reported in 2000. Most deaths occurred between Day 2 and 6, except in Bogotá-Colombia, Spain, UK-Wales, and Mexico, where the deaths occurred on Day 1. The mortality in the first year was 4.3%, but the specific causes of death were not determined in this study.
Conclusion: The prevalence of SIA was about 2.1 per 10,000 births during a 41-year period in 25 centers, with variations in prevalence according to geographical locations. Future research is suggested to analyze changes in trends and the impact of early diagnosis and treatment in mortality.

Abstract
We conducted a retrospective genomic surveillance study of St. Louis encephalitis virus (SLEV) in Texas, USA, to determine the genotypes circulating in the region. By using a custom tiled-amplicon assay with Oxford Nanopore sequencing, we generated 63 genomes from SLEV-positive mosquito pools and viral isolates collected during 2009-2024. Phylogenomic analysis revealed temporal overlap of genotype II and III circulation, but with distinct geographic segregation. Genotype II was confined to Gulf Coast counties with sustained local transmission, whereas genotype III was only in north and west Texas, but with persistent circulation and repeated introductions. We identified the earliest known US genotype III sequences, although their phylogenetic placement leaves the entry point of genotype III into the United States unresolved. Our findings emphasize the need for clinical vigilance in West Texas, where SLEV and West Nile virus co-circulate, and suggest the Gulf Coast may be buffered against foreign genotype introduction.

Shigellosis is a nationally notifiable diarrheal illness caused by gram-negative bacteria. Shigella infection is spread through fecal-oral transmission and sexual contact. Although most infections are self-limited, antibiotics are indicated for severe illness or to reduce transmission in settings with high risk for spread. Since 2015, a growing proportion of cases has been caused by extensively drug-resistant (XDR) Shigella species, defined as being resistant to ampicillin, azithromycin, ceftriaxone, ciprofloxacin, and trimethoprim-sulfamethoxazole. No Food and Drug Administration-approved oral antimicrobial agents are available to treat these XDR infections. To describe U.S. trends and epidemiologic characteristics of XDR shigellosis, CDC analyzed Shigella isolates submitted to PulseNet, CDC's molecular surveillance network for enteric pathogens, during January 1, 2011-October 20, 2023; antimicrobial resistance was characterized using whole-genome sequencing data and antimicrobial susceptibility testing. Among 16,788 isolates with resistance data during this period, 510 (3.0%) were XDR. The percentage of XDR isolates increased from 0% during 2011-2015 to 8.5% in 2023. Species information was available for 505 (99%) of 510 XDR isolates; among those, 333 (65.9%) were Shigella sonnei and 172 (34.1%) were Shigella flexneri. Among patients with XDR shigellosis, the median patient age was 41 years (IQR = 31-54 years) and 86.2% were men. Among patients with available travel history, 76.2% (173 of 227) reported no recent domestic travel and 82.4% (169 of 205) reported no recent international travel. Among 116 persons with available HIV status, 54 (46.6%) reported HIV co-infection. Strengthened surveillance, timely reporting, and targeted prevention strategies are needed to limit transmission of XDR Shigella strains.

Silva-Espinoza JC, Farani PSG, Lopez MF, et al. Identification of Leishmania spp. and Trypanosoma cruzi in bats captured in El Paso County, Texas. PLoS Negl Trop Dis. 2026;20(4):e0014169. Published 2026 Apr 3. doi:10.1371/journal.pntd.0014169
Abstract
Leishmania spp. and Trypanosoma cruzi are protozoan parasites that cause leishmaniasis and Chagas disease, respectively. In the United States, autochthonous transmission cycles of both Leishmania and T. cruzi have been documented, particularly in the southern and southwestern regions. Previous studies in El Paso, Texas, have identified dogs, cats, and several sylvatic mammals as infected hosts for these pathogens; however, the role of bats has remained largely unexplored. Here, we conducted a cross-sectional, observational study of 29 wild bats, opportunistically collected from domestic and peridomestic urban environments in El Paso, Texas, as part of local rabies surveillance. DNA extracted from available heart, spleen, skin, and lung tissues was analyzed by quantitative PCR targeting T. cruzi satellite DNA and Leishmania 18S rDNA, followed by DNA sequencing for confirmation. PCR-based molecular detection identified Leishmania spp. in six bats (24.1%) and Trypanosoma cruzi in thirteen bats (44.8%). DNA sequencing analysis confirmed the presence of parasite-specific DNA in four Leishmania-positive samples and twelve Trypanosoma cruzi-positive samples. Restriction fragment length polymorphism (RFLP) analysis showed that the digestion patterns of the T. cruzi samples differed from those observed in the TcBat reference control. However, given the limited characterization and known genetic variability of the TcBat lineage, as well as the constraints of PCR-RFLP-based typing, these findings do not conclusively exclude the possibility that the detected strains belong to the TcBat genotype. Co-detection of both parasites was detected in 3 out of 18 Tadarida brasiliensis specimens. Mapping of capture sites showed infected bats occurring in both urban and suburban areas of El Paso County. This study provides evidence of the molecular detection of Leishmania spp. and T. cruzi in bats from El Paso, Texas. These findings highlight bats as sylvatic hosts for medically important trypanosomatids in the U.S.-Mexico border region and emphasize the need for expanded surveillance to assess zoonotic risk and its environmental drivers.

Analysis of Epidemiologic Data Using R by Robert Hirsch (2024)
This book addresses the description and analysis of occurrence data frequently encountered in epidemiological studies. Effort is made to emphasize concepts rather than mathematics. Subjects range from description of the frequencies of disease to the analysis of associations between the occurrence of disease and exposure. Those analyses begin with simple associations and work up to complex relationships that involve the control of extraneous characteristics.
