Public Health Status Update for 12/19/2025

Marin County Public Health Unveils Vaccine Resource Hub as Flu Season Intensifies

The latest health briefing from Marin County Public Health, dated December 19, 2025, spotlights a new childhood vaccine resource site, urgent reminders to get the flu shot, guidance to review health coverage for the year ahead, and updates on a Marburg virus event in Ethiopia. Officials also flag a mushroom poisoning alert and introduce an expanded respiratory virus surveillance platform.

New childhood Vaccine Resource Site Now Live

Public Health has launched a dedicated online hub to answer questions about childhood vaccines. The site provides clear, reliable guidance on vaccines such as hepatitis B, along with explanations of common myths and the best available evidence. Officials note that more than a billion hepatitis B doses have been administered globally, underscoring established safety and effectiveness.The birth dose, recommended as 1991, remains a key protection for newborns’ earliest days. Families are encouraged to explore the resources to support informed health decisions.

See for yourself: Time to Get the Flu Shot

The county’s respiratory health portal now aggregates facts on flu, COVID-19, RSV, and local vaccination rates. This season, about 35% of Marin residents are up to date on influenza vaccination, with vaccination coverage for adults age 65 and older slipping from 70% to 56%.With holiday travel and gatherings likely to boost flu activity in January-possibly overlapping with COVID-19 and RSV-getting vaccinated remains a prudent step. The message from public health: vaccines reduce severe illness, protect at‑risk groups, and ease the burden on local healthcare systems. Vaccines are widely accessible across Marin.

Make Sure You’re Covered for the Year Ahead

Now is a strategic moment to reassess health coverage. Upcoming federal program changes could affect affordability,so reviewing options is wise. Covered California makes it straightforward to compare plans and check eligibility for financial support or Medi‑Cal. If you’re unsure where to begin, visit CoveredCA.com or consult the new Access to Care resources for practical guides and local assistance.

Marburg Virus Outbreak in Ethiopia: One Health Perspective

Ethiopia has confirmed an outbreak of Marburg virus disease following a spillover from wildlife. Early investigations point to fruit bats as the natural hosts. the event is notable for its location and for illustrating how climate and ecological shifts can alter bat habitats and human-wildlife interactions. There is no risk to Marin County, but the case underscores the interconnectedness of human, animal, and environmental health. Community efforts to protect wildlife habitats and reduce risky interactions remain important as ecosystems change.

That Fungi Is Poison

Public Health cautions against foraging or handling wild mushrooms after a recent amatoxin poisoning outbreak. The death cap mushroom, common in some Marin areas, can resemble edible varieties.As of early December 2025,dozens of poisoning cases have been reported statewide,including severe liver injury and one fatality. Cooking or processing toxic mushrooms does not neutralize the danger. Pet owners shoudl keep dogs on leashes and check yards for mushrooms. If poisoning is suspected,contact the California poison Control System immediately.

Marin Respiratory Virus Surveillance

A new Respiratory Virus Dashboard consolidates local data on COVID-19, influenza, and RSV in one place. This tool aims to help residents gauge risk, vaccination progress, and local trends across respiratory illnesses.

Resource Link Library: Where to Find Help

The Public Health Resource Library aggregates practical links for staying healthy, with an emphasis on access to care, nutrition security, and public benefits. Highlights include:

Public Health and Access to Care

Official guidance from state and local health authorities is available through the Respiratory Viruses Hub and vaccine resources pages. You can locate vaccine sites, booster information, and free COVID-19 testing options. For coverage help, tools exist to connect residents with covered California, Federally Qualified Health Centers, and other programs.

Nutrition Security & Public Benefits

Residents can locate free groceries and meal assistance through food-bank networks and explore benefits programs that help with health coverage, food aid, and cash assistance. Eligible individuals can use online eligibility tools to determine WIC and other supports.

Stay Informed

To receive regular updates, residents can subscribe to status updates, access past briefs, or follow local public health channels on social media. This consistent flow of information helps the community prepare for seasonal health risks and public health emergencies.
