- California public health officials are warning consumers and businesses not to eat, serve, or sell recalled Happy Hens brand organic in-shell eggs due to Salmonella Enteritidis contamination. - As of September 8, 2026, 23 California residents have been linked to the outbreak, with seven hospitalizations and no deaths reported and illness onsets spanning June 21 to August 16. - Whole genome sequencing matched Salmonella Enteritidis from two positive environmental samples collected at the Happy Hens farm to the strain isolated from sick individuals. - Happy Hens of Ramona, California voluntarily recalled the eggs on September 8, 2026, with distribution reaching restaurants, grocery stores, and farmers markets across Southern California and the Central Coast.
- COVID-19 infections are growing or likely growing in all 50 states, with active outbreaks in at least 15 states and territories as of mid-August. - Experts report that summer peaks have surpassed winter peaks since 2024, with California's 2025 summer peak "much higher" than its winter peak. - Nationwide test positivity reached nearly 4% last week, still below the more than 9% recorded during the same week a year ago. - Health officials urge vaccination ahead of an anticipated September transmission peak, with an updated XFG-targeting vaccine expected in early fall.
- A Los Angeles County study found that 71% of low-titer positive serology specimens from patients with illness consistent with fleaborne typhus (FBT) were PCR-positive for Rickettsia typhi, underscoring the value of molecular testing for diagnosis and case detection. - Most PCR-positive specimens (91%) were collected within 10 days of illness onset, with some positive up to 15 days, suggesting the previously recommended 1-week PCR testing window is too restrictive. - All 81 PCR-positive specimens tested positive for R. typhi and none for R. felis, reinforcing that R. typhi is the primary etiologic agent of FBT in California. - The findings support wider commercial availability of Rickettsia PCR testing to enhance clinical diagnosis and public health surveillance of FBT.
- California has confirmed 52 measles cases in 2026, more than double the number reported in 2025, with most cases occurring in unvaccinated individuals. - Nearly 2,300 measles cases were reported across the United States in 2025, the highest annual total since 2000, with 2026 cases on pace to surpass that figure. - CDPH Director Dr. Erica Pan reaffirmed confidence in the safety and effectiveness of the MMR vaccine, which California requires for school and childcare entry. - California maintains more than 95% MMR vaccine coverage among kindergarteners, a level that can prevent large measles outbreaks but still requires continued vaccination.
- Cal State Fullerton researchers began collecting environmental samples from three Ladera Ranch parks after at least six children were diagnosed with Ewing sarcoma since 2013. - Surrounding areas have recorded 9 to 12 cases of Ewing and synovial sarcoma with six deaths, though a 2024 county review found no unusual pattern. - Residents are pressing the homeowners association to stop pesticide spraying, while a law firm investigates possible environmental exposures. - State and local agencies, including the California Cancer Registry, are conducting an updated review of cancer data, with findings expected in coming weeks.
- A Northern Californian became the fourth person ever diagnosed with Rickettsia lanei, a newly recognized tick-borne bacterium from the spotted fever group, with the case confirmed in April 2026. - All four documented human cases have required hospitalization, including intensive care, though no deaths have been reported; symptoms closely mimic Rocky Mountain spotted fever. - The California Department of Public Health urges clinicians to begin doxycycline treatment immediately upon suspicion of spotted fever group Rickettsia infection rather than waiting for lab confirmation. - Infected Pacific Coast ticks have been identified in Contra Costa and San Mateo counties, prompting renewed public health warnings about tick safety in Northern California.
- The WHO confirmed the Andes virus, a hantavirus capable of human-to-human transmission, is responsible for the outbreak aboard the MV Hondius cruise ship that killed three people. - Five laboratory-confirmed cases and three additional suspected cases have been reported, with California residents among the 147 passengers and staff on board. - Officials emphasize the risk to the general public is "extremely low," as transmission requires close and prolonged contact, and the virus does not spread like SARS-CoV-2. - The incubation period for Andes hantavirus can extend up to six weeks, meaning additional cases may still emerge as monitoring continues.
- At least 13 infants across 10 states have been hospitalized with botulism after consuming ByHeart Whole Nutrition Infant Formula between August and November 2024. - Preliminary tests by California health officials detected bacteria that produces botulism toxin in the recalled formula, marking an extremely rare occurrence in powdered infant formula. - ByHeart voluntarily recalled two specific lots of their formula with lot numbers 206VABP/251131P2 and 206VABP/251261P2, both with December 1, 2026 expiration dates. - All affected infants received BabyBIG treatment, the only available therapy for infant botulism, and no deaths have been reported in this outbreak.
- A child in Alameda County, California has tested positive for H5N1 bird flu despite having no known contact with infected animals, raising concerns about potential transmission pathways. - CDC testing confirmed the virus strain is similar to those detected in dairy cattle and poultry, though the child had low viral levels, was not likely infectious to others, and has since recovered. - This case marks a concerning development in the ongoing bird flu outbreak that has infected 58 people across seven U.S. states this year, with California accounting for 32 cases.
