Avian Influenza (Bird Flu)
The US Centers for Disease Control and Prevention (CDC) has confirmed 5 suspected H5 avian flu cases in California dairy workers, according to updated tables from the CDC and the California Department of Public Health (CDPH). California now has 11 H5 cases in dairy workers.
So far this year, 25 human H5 cases have been reported in the United States, all but 1 involving exposure to infected cows or poultry.
Dairy workers in California continue to face a daunting threat from ongoing spread of the virus in the state’s dairy cows. The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed 15 more outbreaks in California dairy herds, bringing the state’s total to 120 and the national total to 320 across 14 states.
USDA confirms outbreaks in Utah and Washington poultry flocks
In other avian flu developments, APHIS today confirmed an outbreak at a commercial poultry farm reported by Utah earlier this week. The facility in Cache County is a layer farm that has 1.8 million birds.
Also, the agency confirmed an outbreak at a layer farm in Washington, which involves a facility in Franklin County that has nearly 840,000 birds. The event marks Washington’s first outbreak in poultry since December 2023.

A study conducted at a California hospital found that people considered highly socially vulnerable were significantly more likely to be diagnosed with severe Clostridioides difficile infection (CDI) and die from it than less vulnerable people, researchers reported yesterday at IDWeek 2024.
The study by researchers at Loma Linda University Medical Center included 206 adults admitted for CDI, which causes diarrhea and colitis, from January 2020 to June 2021. To assess the impact of external factors on CDI severity, and mortality, the researchers used the Centers for Disease Control and Prevention’s Social Vulnerability Index (SVI), a composite measure of communities based on four major themes: socioeconomic status, housing characteristics, race/ethnicity status, and housing and transportation.
Patients in the study with an SVI score of less than 0.5 were considered low vulnerability, while people above 0.5 were considered highly vulnerable.
Large disparities across all SVI themes
The analysis found that high vulnerability scores across all four SVI themes were associated with increased CDI severity and mortality. Patients with high vulnerability scores in socioeconomic status and housing characteristics were three times more likely to have severe CDI than those with low vulnerability scores, while patients with high vulnerability scores for housing and transportation—including those living in multiunit structures, mobile homes, group quarters, and lacking a vehicle—were more than twice as likely to have severe CDIcompared with people with low scores.
When considering race/ethnicity status, patients with high vulnerability scores were 37 times more likely to be diagnosed with severe CDI and nine times more likely to die than those with low scores.
“We need to conduct further research to gain a deeper understanding of the correlations between C. diff severity and mortality, race and environmental and socioeconomic factors,” Timothy Afable, PharmD, pharmacy resident at Loma Linda University and presenting author, said in an IDWeek press release. “This study is only a starting point to a broader understanding of health equity and the potential vulnerabilities patients with C. diff face.”

Data collected at the University Hospitals of Cleveland show that overall US vaccination rates for influenza, SARS-CoV-2, and respiratory syncytial virus (RSV) remain below 50%, with Black individuals less likely to be vaccinated than their White peers.
The data were presented this week at IDWeek in Los Angeles, and based on information collected from the US Centers for Disease Control and Prevention’s Social Vulnerability Index (SVI), which looks at socioeconomic status, housing, and neighborhood characteristics that can be social determinants of health.
Looking at the Cleveland metropolitan area, the researchers analyzed 341,029 patients who were diagnosed as having acute respiratory infections at University Hospitals of Cleveland between October 2023 and April 2024.
More ED visits in low-income neighborhoods
Black patients were overrepresented as 37% of the patient population, despite making up 14% of Cleveland’s population. Researchers found lower vaccination rates in areas with higher social vulnerability and in predominantly Black neighborhoods but higher emergency department (ED) visits for acute respiratory infections in those areas.
The study’s findings maintain that neighborhood factors and race are significantly associated with vaccination status against common respiratory viruses
"Even when controlling for demographic factors, household income, health insurance coverage and geographic location, the study’s findings maintain that neighborhood factors and race are significantly associated with vaccination status against common respiratory viruses," said Elie Saade, MD, medical director of infection control and quality at University Hospitals of Cleveland, in the news release. "Disparities this vast are not to be overlooked—they require multifaceted interventions that meet people where they are socially and increase access to essential preventive measures."
