Salmonella Outbreaks Tied to Backyard Poultry Prompt Michigan Health Advisory

Michigan health officials warn of three multistate Salmonella outbreaks linked to backyard poultry, especially baby chicks and ducklings, with 184 cases across 31 states including 21 in Michigan. The strains involved are Salmonella enteritidis, mbandaka, and saintpaul, and many cases involve children under five. Transmission occurs through handling birds and contaminated environments. Officials urge keeping poultry outdoors, avoiding indoor housing, washing hands after contact, keeping birds away from food areas, and seeking medical care if infection is suspected.

Cruise-ship hantavirus outbreak exposes gaps in early diagnosis and prevention

Cruise-ship hantavirus outbreak exposes gaps in early diagnosis and prevention

In a Washington Post opinion, Abraar Karan argues that the Hondius hantavirus outbreak—and a prior Argentina incident—expose how slow recognition and limited on-site testing hinder outbreak control. Hantavirus can spread between people and cause severe heart-lung illness, with symptoms that are often non-specific and appear weeks after exposure, making early diagnosis challenging. The piece advocates more proactive travel-health screening, broader and faster diagnostics (like metagenomic sequencing and PCR panels), and greater investment in point-of-care tests to curb shipboard and cross-border transmission, while noting cost and biosafety barriers remain substantial.

California Faces Record TB Outbreaks as Rates Surpass U.S. Average

California Faces Record TB Outbreaks as Rates Surpass U.S. Average

California posted a record 2,150+ TB cases in 2025 with a rate of 5.4 per 100,000—nearly double the national rate. A CDC/MMWR review found about 50 large TB outbreaks from 2017–2023, many linked to family/social networks or congregate settings and associated with factors like housing insecurity and substance use. The Bay Area saw outbreak testing at Archbishop Riordan High School, and experts say preventing outbreaks will require stronger genomic surveillance, better TB programs, and addressing homelessness and related social determinants of health.

Rotavirus surge in the US spotlights vaccination gaps

Rotavirus surge in the US spotlights vaccination gaps

CDC data show a rise in US rotavirus infections, with 7.3% of tests positive in the week ending April 4 (last year’s peak was 6.77%), likely tied to declining vaccination rates post-COVID and a post-pandemic rebound. With no antiviral treatment, prevention hinges on completing the rotavirus vaccine series (Rotateq and Rotarix) and ongoing hygiene; severe cases require IV rehydration and supportive care, especially for infants and young children.

California’s seven-year high in measles prompts renewed outbreak alarms

California’s seven-year high in measles prompts renewed outbreak alarms

California has at least 40 measles cases in 2026, the most in seven years, primarily among unvaccinated individuals and amid outbreaks in Riverside, Shasta, and Sacramento–Placer counties. Nationally, cases approach 1,714 as kindergarten vaccination rates dip below the 95% herd-immunity target, fueling concerns that reduced immunity could lead to endemic transmission despite California’s strict vaccine mandates.

Kent meningitis B outbreak prompts urgent NHS warning and vaccination push

Kent meningitis B outbreak prompts urgent NHS warning and vaccination push

An outbreak of meningitis B in Kent has prompted urgent NHS warnings as cases rise to 27 (two deaths), with links to Canterbury Christ Church University and a London student; authorities are arranging antibiotics for those exposed and rolling out a targeted MenB/MenACWY vaccination drive for University of Kent students. The NHS stresses that meningitis B is serious and can progress rapidly, so seek urgent care if experiencing symptoms such as high fever, severe headache, vomiting, stiff neck, or a non-blanching rash. Vaccines are available and catch-up doses are offered to those up to age 25, which is especially important for new university entrants.

Kent meningitis B outbreak prompts NHS warning and student vaccination drive

Health chiefs are investigating 27 meningitis cases linked to an outbreak in Kent, including infections at Canterbury Christ Church University and a London student, with two deaths. Preventive antibiotics are being offered to visitors to a Kent club linked to the outbreak and a vaccination drive for University of Kent students is underway. Meningitis B (Neisseria meningitidis group B) can progress quickly to sepsis; symptoms include high fever, severe headache, vomiting, stiff neck, rash and sensitivity to light. If meningitis is suspected, call 999 or go to A&E; vaccines exist as part of the UK schedule, with catch-up opportunities up to age 25 for those who missed school vaccination.

Measles resurges in the U.S., signaling cracks in public health readiness

Measles resurges in the U.S., signaling cracks in public health readiness

Measles has reappeared in the United States after elimination in 2000, with outbreaks spreading across about 30 states and roughly 1,300 infections by March 2026. The resurgence is driven by falling MMR vaccination rates below the 95% herd-immunity benchmark, creating unvaccinated pockets that risk serious illness, hospitalizations, and long-term complications. The outbreaks carry heavy economic costs and serve as a warning about the nation’s ability to respond to broader infectious threats, as public trust in health institutions continues to erode.

Measles comeback exposes cracks in U.S. public health

Measles has reappeared in the U.S. after being eliminated in 2000, driven by falling MMR vaccination rates that have dropped below the 95% herd-immunity target in many areas. By March 2026 there were about 1,300 cases this year across at least 30 states, ongoing outbreaks and hospitalizations, and three deaths in 2025. The resurgence signals not only health risks but broader vulnerabilities in public trust and in our ability to respond to infectious threats, with potential loss of elimination status in North America and large economic costs. Public health efforts now must focus on vaccination, rapid case detection, and maintaining trust in health institutions to prevent wider spread.

Measles Bounces Back, Exposing Cracks in US Public Health

Measles Bounces Back, Exposing Cracks in US Public Health

Measles has re-emerged in the US after decades of rarity, driven by vaccination gaps that push local pockets below the 95% herd-immunity threshold. Outbreaks have spread from Texas in 2025 to Utah/Arizona and South Carolina in 2026, with about 1,300 cases by March 2026 (2,283 in 2025 and 3 deaths). The resurgence risks hospitalizations, pneumonia, SSPE, and substantial economic costs, and it highlights eroding public trust in vaccines and health institutions, as well as the possibility that the U.S. and neighboring countries could lose elimination status.
