(Santa Ana, CA) – The GKN Aerospace hazardous material incident in Garden Grove is transitioning out of the emergency response phase. Beginning Friday, May 29, the OC Health Care Agency (HCA) as the County’s Certified Unified Program Agency (CUPA) will take the lead as the oversight authority for site cleanup and waste removal. The HCA, in its regulatory role, will work closely with GKN Aerospace throughout this next phase. During the cleanup process, air monitoring will be conducted at the fence line and in the community under the oversight of South Coast Air Quality Management District (AQMD). The U.S. Environmental Protection Agency (EPA) will provide technical advisory support to South Coast AQMD and the HCA throughout this next phase. Updates regarding the site cleanup and waste removal will be posted on www.occupainfo.com. Information regarding the GKN Aerospace hazardous material incident can be found here: https://www.ocgov.com/gkn-aerospace-hazmat-incident.
Each May, we recognize two important observances that highlight how our community can stay safe, prepared, and supported: Trauma Injury Prevention Month and Emergency Medical Services (EMS) Week. When woven together, these observances remind us that preventing injuries and ensuring rapid, skilled emergency response are essential parts of a healthy community.
Trauma remains a leading cause of death and disability across all ages. Many injuries, whether from falls, motor vehicle collisions, pedestrian incidents, or everyday activities, are preventable. Trauma Injury Prevention Month encourages each of us to take simple, practical steps that reduce risk and promote safety in our homes, workplaces, and neighborhoods.
This year, one area drawing increasing attention is the rise in injuries related to bicycles, scooters, and e-mobility devices - including e-bikes. As more children, teens, and adults turn to e-bikes and e-scooters for recreation and transportation, emergency departments and EMS teams are seeing more crashes involving excessive speed, lack of appropriate helmet use, and limited rider experience. Practicing safe riding habits makes a meaningful difference. Riders should always wear a properly fitted helmet, follow traffic laws, stay alert to cars and pedestrians, and choose speeds appropriate for their environment. Parents and caregivers can help by ensuring young riders understand how to operate e-bikes safely and by choosing models appropriate for their age and skill level.
At the same time, EMS Week honors the dedicated professionals who respond when emergencies happen. Paramedics, Emergency Medical Technicians (EMTs), dispatchers, and first responders work around the clock to deliver life-saving care, often within minutes. Their readiness and expertise form a critical safety net when prevention is not enough. Together, prevention and emergency response strengthen the resilience of our entire community.
This month is a good time to reflect on what we can do individually and collectively to reduce preventable injuries and support the emergency responders who serve us. A few simple habits make a meaningful difference:
Stay attentive on the road. Avoid distractions, wear seat belts, and follow posted speeds.
Prevent falls at home. Remove tripping hazards, improve lighting, and install handrails if needed.
Practice safe storage. Keep medications, chemicals, and sharp objects securely out of reach of children.
Ride bikes, e-bikes, and scooters safely. Wear a helmet, obey traffic laws, and keep speeds appropriate for the setting.
Be prepared. Learn basic first aid and CPR, know how to call 9‑1‑1 effectively, and keep emergency contacts readily available.
Supporting EMS professionals also strengthens community health. You can: Learn about local EMS resources and share them with family, friends, and neighbors.
Participate in community CPR or Stop the Bleed trainings.
Make 9‑1‑1 calls efficiently by staying calm, answering questions clearly, and providing your exact location.
By combining prevention with readiness, we create safer environments and ensure that help is available when it is needed most. Prevention reduces the number of emergencies; EMS ensures rapid care when prevention falls short. Together, these efforts form a powerful partnership that protects health and saves lives.
As we honor Trauma Injury Prevention Month and EMS Week, let’s recognize the role we each play. Small actions - buckling a seatbelt, securing a ladder, riding bikes, scooters, and e-bikes responsibly, or learning a lifesaving skill can prevent injuries and support the dedicated professionals who respond when seconds matter.
Together, we can build a safer, stronger, and healthier Orange County.

(Orange, CA) – A bat found in Irvine Regional Park has tested positive for rabies. The bat was found on Sunday, May 24, 2026 at 9:30 a.m. Anyone who may have had physical contact with the bat or saw someone else having contact with the bat is asked to call the OC Health Care Agency (HCA) Communicable Disease Control Division at (714) 834-8180 during business hours or after hours to determine the risk for rabies. Owners of pets who may have had contact with this bat should contact their veterinarian.
The rabies virus is found in an animal’s saliva and is transmitted to people by a bite from a rabid animal. Although very rare, contamination of the eyes, mouth or an open wound by the saliva of a rabid animal can also transmit rabies. Most cases of human rabies in the United States in recent years have resulted from bat strains of rabies; bats have very small teeth, and their bites may go unnoticed.
Once a person begins showing signs and symptoms of rabies, the disease is nearly always fatal. For that reason, preventive treatment to stop the rabies virus from causing illness is given to anyone who may have been exposed to rabies. Medical assistance should be obtained promptly after an exposure so any wound can be cleaned and preventive treatment can be started. This treatment is safe and effective.
The HCA and OC Animal Care recommend the following actions to minimize the risk of rabies:
Avoid all contact with wild animals.
Vaccinate all cats and dogs against rabies.
Do not sleep with open unscreened windows or doors.
If bats are seen inside the house or other structure, close off the area and contact animal control. Once the bat(s) have been removed, close off any areas allowing entrance into the house.
Do not leave pet food outside where it will attract wild animals.
Immediately wash all animal bites with soap and water, being sure to flush the wound well, then contact your doctor.
Report all animal bites to OC Animal Care.
Potential exposure to a bat or other wild animal should be reported to HCA Communicable Disease Control Division at (714) 834-8180. To report a bat in your home or an animal bite, contact OC Animal Care at (714) 935-6848. More information about rabies is available at the Centers for Disease Control website at http://www.cdc.gov/rabies/.
Health Advisory: Information on Methyl Methacrylate (MMA)
A hazardous materials incident in Garden Grove has led to mandatory evacuation orders due to the potential release of Methyl Methacrylate (MMA) a highly flammable and potentially toxic chemical commonly used in plastics, coatings, and manufacturing.
Evacuation boundaries were established using modeling scenarios to ensure public safety that include modeling of a potential on-site explosion. Everyone within the designated evacuation zone is urged to comply with these orders until authorities confirm it is safe to return.
Emergency teams are focused on keeping the liquid MMA stored in the special enclosed tanks in a stable temperature range to prevent further reaction and vapor production. Cooling and containment operations are ongoing. Air quality officials have deployed multiple stationary and mobile air monitors and have not detected any contaminants in the air to date.
Exposure is not expected as long as evacuation orders are followed. If you are exposed to MMA, you may or may not develop health effects. Those with underlying medical conditions or experiencing symptoms such as shortness of breath, throat or eye irritation or vomiting may need to be seen by a medical professional. Call the California Poison Control System at 1-800-222-1222 if you are experiencing symptoms and need to speak with an expert about how to proceed.
On May 15, 2026, the Democratic Republic of Congo and the Republic of Uganda officially declared an outbreak of Bundibugyo virus disease (BVD), a type of Ebola disease caused by Bundibugyo virus. WHO has declared the Ebola disease outbreaks in DRC and Uganda to be a public health emergency of international concern.
As of May 18, the DRC has reported 10 confirmed cases, 336 suspected cases and 88 suspected deaths. The Uganda Ministry of Health has reported two cases of BVD in Kampala, including one death, in travelers from DRC with no known epidemiologic link to other cases.
On May 17, 2026, a U.S. citizen in the DRC who had known high‑risk exposures and had developed symptoms tested positive for BVD. The U.S. government is working to evacuate this individual and 6 other U.S. citizens who also had known high-risk exposures, to a facility in Germany to ensure access to treatment and close observation.
No suspected, probable, or confirmed cases related to these outbreaks have been reported within the United States or California. At this time, CDC and CDPH assess the immediate risk to the general US public as low.
Clinicians should suspect BVD in a patient who has traveled to DRC or Uganda in the last 21 days, AND who has compatible symptoms (e.g., fever, headache, muscle and joint pain, fatigue, loss of appetite, gastrointestinal symptoms, or unexplained bleeding), AND has reported epidemiologically compatible risk factors within the 21 days before symptom onset (see Recommendations for Clinicians).
If there is suspicion for BVD, healthcare providers should immediately take infection control precautions specific to Ebola disease and notify the local health department (LHD).
Travelers who have been in DRC or Uganda in the last 21 days should contact their LHD if they develop symptoms concerning for BVD. Before going to the doctor's office, emergency room, or other clinical setting, they should contact the doctor or other healthcare provider and inform them about the recent travel, symptoms, and risk factors.
The California Department of Public Health (CDPH) is closely monitoring an outbreak of Bundibugyo virus disease (BVD), a type of Ebola disease caused by Bundibugyo virus, in the Democratic Republic of the Congo (DRC) and the Republic of Uganda. To date, no cases of BVD related to these outbreaks have been reported in the United States or other countries outside of the DRC and the Republic of Uganda. At this time, the CDC assesses the immediate risk to the general U.S. public as low.
On May 19, 2026, CDC released a Health Alert Network (HAN) Advisory providing national-level information and guidance regarding the Ebola disease outbreak in the Democratic Republic of the Congo and Uganda. This CAHAN message supplements the CDC HAN by providing additional California-specific context and guidance for local health departments and healthcare partners.
In recognition of Mental Health Awareness Month, let’s highlight a condition that affects about 1 in 7 individuals after childbirth but is often missed: Postpartum Depression (PPD). PPD is a serious, longer lasting mood disorder that can occur anytime during pregnancy or within the first year after birth. It may involve intense sadness, anxiety, exhaustion, or feeling disconnected from the baby. PPD is not a character flaw or a personal failure—no one can guarantee prevention. However, recognizing symptoms early and having strong support can make a meaningful difference.
Below are strategies that may help reduce risk and support early detection and treatment.
Sleep. Before delivery, moms and new parents can start discussing a realistic sleep plan with their support system. Aiming for 4–5 hours of uninterrupted rest can be helpful, with a partner or support person caring for the newborn during that window. Many families find it useful for the birthing parent to go to bed early (for example, 8 p.m. to 1 a.m.) and then switch roles.
Realistic expectations around breastfeeding. New parents often hear strong messages about the benefits of breastfeeding, yet may not be aware that it can be challenging—or not possible—for some mom–baby pairs. Moms wishing to breastfeed should seek early lactation support, including in the hospital. There are many resources and supports available for breastfeeding moms (see Orange County Community Breastfeeding Resources). If breastfeeding starts to feel overwhelming, frustrating, or emotionally distressing, supplementing with formula can be a healthy and supportive choice while continuing to breastfeed. The mental wellbeing of the birthing parent is an important part of any feeding decision. Choosing to stop breastfeeding — or not to start at all — is never a sign of personal failure. It’s a thoughtful decision made with your well‑being and your baby’s needs in mind. If formula is used, skin-to-skin time during feedings can still support bonding.
Breaks and personal time. Planned breaks without childcare or household responsibilities are essential. Ideally this is more than an hour each day, but even a few breaks per week can support mental health. This time can be used for showering, light exercise, or simple relaxation.
Accepting help. Support networks often want to be involved but may not know how. Creating a list of tasks others can help with—preparing a meal, holding the baby while the caregiver showers, offering transportation, or providing companionship—can make it easier to say “yes” when help is offered. See the California Surgeon General's "One Small Thing" for ideas.
Exercise. Once medically cleared, engaging in regular physical activity can significantly improve mood for new moms. Activities like walking with the baby in a stroller or carrier may be more accessible in the early months. The key is choosing something enjoyable and sustainable.
Community and connection. Having a supportive community of other new parents can make a tremendous difference. Many hospitals, clinics, and community organizations offer parent and baby groups that provide encouragement, practical guidance, and a comfortable setting to connect with others.
Mindful presence. Moms experiencing PPD or postpartum blues may find it difficult to enjoy time with their newborn due to worry or racing thoughts. Mindfulness can help build connection and reduce depressive symptoms. A simple loving‑kindness practice—while holding a calm, feeding, or sleeping baby—can involve focusing on the breath, letting thoughts pass, envisioning a sense of safety around both parent and baby, or silently repeating phrases such as “may you be safe, may you be healthy, may you be loved.”
Early detection. Even with prevention strategies, some individuals will still experience PPD. It does not occur due to lack of effort and can affect anyone. Postpartum “blues” are common and usually resolve within 2–3 weeks. When symptoms last longer, become severe, or interfere with daily function, PPD may be present. Symptoms can also include intense anxiety or difficulty sleeping. It is important to talk with loved ones or healthcare providers, even if medication is not desired—there are many treatment options. The National Maternal Mental Health Hotline is a free, confidential service available 24/7 by calling or texting 1-833-TLC-MAMA (852-6262). Rare but serious symptoms, such as hearing voices, believing something bad has happened to the baby, or thoughts of harming oneself or the child, require immediate professional support, and the individual should not be left alone with the baby until care is in place. Call OC Links at 855-625-4657 for 24/7 crisis support.
Expectant management. A history of depression increases the risk of PPD. Addressing factors such as trauma, significant stress, ineffective coping habits, or negative self-image with a therapist during pregnancy can be protective. Planning postpartum follow up with a psychiatrist or therapist is beneficial. Those who have previously responded well to medication may discuss planning ahead with their provider—either having medication available if symptoms emerge or starting preventative treatment right after delivery. Mom, along with her partner or support person, should review the early signs of PPD and prepare a plan for addressing symptoms if they occur.
While PPD cannot be fully prevented, addressing common challenges and planning in advance can reduce the risk of prolonged or untreated symptoms. Feelings of guilt, hopelessness, or being overwhelmed can make it difficult to seek help, but early support can significantly improve recovery and well‑being for both the caregiver and the baby.

The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to alert clinicians, public health practitioners, and travelers about a new outbreak of Ebola disease in the Democratic Republic of the Congo (DRC) and Uganda caused by the Bundibugyo virus (species Orthoebolavirus bundibugyoense). The risk of spread to the United States is considered low at this time. As a precaution, this Health Advisory summarizes CDC recommendations for U.S. health departments, clinical laboratories, and healthcare workers about potential Ebola disease case identification, testing, and biosafety considerations in clinical laboratories.
The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Update to inform clinicians and health departments about testing available for patients with suspected hantavirus infection to include Andes virus. CDC first issued a Health Advisory (HAN-00528) about this outbreak on May 8, 2026. Hantaviruses are a group of viruses that typically spread to people who come in contact with sylvatic rodents. These viruses can cause severe illness or death in humans. Andes virus, a type of hantavirus endemic in South America, is the only type of hantavirus that is known to spread from person to person. Several other New World hantaviruses are endemic to the United States and are not transmissible from person to person. New World hantaviruses can cause hantavirus pulmonary syndrome (HPS), a potentially serious disease that can cause damage to the lungs.
On May 2, 2026, an outbreak of Andes virus on a cruise ship was reported to the World Health Organization (WHO). This outbreak has raised the possibility of cases being imported to the United States. As of May 18, no confirmed cases of Andes virus associated with the outbreak on the cruise ship have been reported in the United States. Therefore, the overall risk to the American public is still considered extremely low at this time. CDC and health departments in several states are monitoring the health of U.S. passengers from the ship and U.S. air travel contacts of symptomatic ship passengers who were subsequently confirmed to have Andes virus infection. This Health Update informs clinicians about testing and consultation that are available for Andes virus and other hantaviruses endemic to the United States, South America, and other nations.
