Pasadena resident tests positive for whooping cough after visiting children's museum
The Pasadena Public Health Department announced the infection on Thursday as whooping cough cases continue to rise across the United States. There have been more than 8,470 cases reported nationally in 2025, which is about double the cases reported in the same time period last year, according to data from the U.S. Centers for Disease Control and Prevention.

Health officials warned anyone who visited Kidspace from 1:30 p.m. to 5 p.m. on April 25 to monitor their household, and especially children, for symptoms such as a runny nose, a low-grade fever and difficulty breathing.
Anyone feeling ill after visiting the museum during this window is urged to visit their healthcare provider and avoid contact with babies and pregnant women. Infections can be confirmed with a nasal swab.
High-risk individuals, such as infants younger than 1 and pregnant women, may need preventive antibiotics even if they are not showing symptoms, health officials said.
Whooping cough is caused by a type of bacteria called Bordetella pertussis, which attack the upper respiratory system and can cause airways to swell, according to the CDC.
Symptoms typically begin five days to three weeks after exposure with a mild cold and a fever of less than 100.4 degrees. In severe cases, symptoms will progress to coughing fits that cause gasping or whooping sounds and vomiting. Infants may not display the telltale whooping cough, but turn blue, red or gag due to difficulty breathing.
California whooping cough cases more than quadrupled last year — from 644 in 2023 to 2,753 in 2024, according to the state health department. In the past six months, two babies in Louisiana and a 5-year-old in Washington have died from the illness.

There are vaccines for whooping cough. As early as 2 months old, babies get the first in a series of DTaP shots, which also protects against diphtheria and tetanus. The vaccine is administered again at 4 months, 6 months and then again at 15 to 18 months and when the child is between 4 and 6 years old.
The vaccine series is part of school-entry immunization requirements in all 50 states, and a booster shot is recommended for pregnant women.
Experts attribute the uptick in infections to decreasing vaccination rates. Last year, the share of children with exemptions to school-entry vaccinations across the country hit an all-time high of 3.3%, according to the CDC.
'There's unfortunately been increasing anti-vaccine sentiment in the United States,' Dr. Ericka Hayes, who works at the Children's Hospital of Philadelphia, told the Associated Press. 'Our recovery is not nearly as quick as we expected it to be and we needed it to be. And again, when you fall below 95% for vaccinations, you lose that herd immunity protection.'

14 easy ways to fit more movement into your day — and potentially live longer
You know the drill — exercise could help you feel better, prevent disease and live longer. But that knowledge may not always get you motivated enough to head to the gym. Whether you have 'gymtimidation' or working out isn't your thing — you can still start improving your health by making simple but powerful changes in how you move as you go about your usual routine. Optimizing movement in your daily activities is a practice based on the concept of non-exercise activity thermogenesis, or NEAT, said Dana Santas, a certified strength and conditioning specialist known as the 'Mobility Maker.' 'It includes all the movement we do throughout the day that isn't part of a formal workout — things like walking to the kitchen, doing chores, standing instead of sitting, or even fidgeting,' Santas, a mind-body coach in professional sports, said via email. 'These small actions can really add up and play a meaningful role in our daily energy expenditure and metabolic health.' 'But NEAT isn't just about burning more calories — it's also about how our bodies are built to move and function. From a mind-body perspective, all movement is significant,' said Santas, author of 'Practical Solutions for Back Pain Relief.' Americans spend around six to eight hours a day sitting, according to the US Centers for Disease Control and Prevention. Spending a lot of time sitting has been associated with a higher risk of premature death, heart disease, type 2 diabetes and obesity. But you can counter being sedentary by becoming more aware of the ways you're moving throughout your day and considering how to get more active in a way that works for you. 'Frequent, varied movement through the day supports joint mobility, muscle health, bone density, circulation, mental focus, and even sleep,' she added. That's why Santas often encourages people to incorporate 'movement snacks,' or short bouts of activity that break up long periods of sitting. The more vigorously you do some of these activities, the better, said Nicholas Rolnick, a physical therapist based in New York City. You can track that with an accelerometer (a wrist-worn motion sensor) since it measures your heart rate, or by using the equipment-free 'talk test,' which helps you gauge intensity according to your breathing and capacity for conversation during exercise. 1. While your food is heating up, do some squats or wall sits or take a lap around the office floor instead of just waiting there or scrolling through your phone. 'Working on your lower extremity strength, getting your heart rate up — those are all things that will improve your physical fitness,' Rolnick said. 'And when you get your heart rate up, your cardiovascular capacity (improves).' If you want to improve your strength and endurance over time, try doing one squat every eight seconds and then, in a couple weeks, a squat every four seconds, Rolnick said. You can also gradually increase your ability to do wall sits by starting out with a small knee bend then moving to a full 90-degree sit over time. 2. When you're running errands, park as far away from stores as possible. That can help add brief periods of activity to your schedule and increase your daily step count. 3. Better yet, walk or bike to nearby errands instead of driving. 'What also is a nice secret weapon in running errands and doing these is wearing a backpack and putting in a couple of books or things,' Rolnick said. 'That increases the workload that the legs and the heart have to do because the metabolic demands are going to be increasing.' 4. Skip the elevator and take the stairs. And if there is an escalator, walk up instead of letting it do all the work for you. Stair-climbing has been associated with improved body composition and lower levels of serum or blood lipids, including cholesterol and triglycerides, Rolnick said. You can maximize the benefits by skipping a stair or two, increasing your range of motion and the demand on your legs. The challenge improves strength and blood sugar control, he added. Climbing more than five flights of stairs at home per day has been associated with a 7% to 9% lower risk of all-cause mortality compared with not climbing stairs. 5. When you're on the phone, walk around the block instead of sitting on the couch. Walking has been linked with a lower risk of diabetes, cancer, cardiovascular disease and dementia. 6. While enjoying your favorite show, get active at the same time. You can lift weights, squat, do other resistance exercises, or walk or run on a treadmill. 7. Invest in a standing desk and use it. Even if standing while working isn't active movement, it still engages more muscles than sitting does. Desk-bound workers have been found to have a 16% higher risk of premature death from all causes and a 34% higher risk of dying from cardiovascular disease, according to a 2024 study. But you should still break up bouts of standing with movement breaks, a 2024 study based in Australia suggests. Standing for hours has been associated with greater odds of issues such as varicose veins or feeling lightheaded when standing. 8. Take your work meetings outside when possible. It's another way to counteract the health harms of sitting for too long. 9. Use a desk treadmill or walking pad during your workday. 10. While you're brushing your teeth, try some calf raises. If you have balance issues, practice the exercise on its own first and place your hand on the wall before attempting to multitask, Santas said. Alternatively, she likes doing squats or wall sits while brushing her teeth. 11. Carry your grocery purchases to your car instead of using a cart. 'When you accumulate volume at even low intensities, you're going to be able to improve your fitness,' Rolnick said. 12. If you already go on walks, increase your pace. A faster gait — defined in one study as more than 4 miles (6.4 kilometers) per hour — has been associated with a 40% lower risk of type 2 diabetes and improved cognitive health and mobility. You can also try adding a few walking lunges at various points during the walk, or step-ups on a curb or bench, Santas suggested. 13. Do your chores faster. By vacuuming more quickly, for example, you're increasing the demand on your arms and legs and upping your heart rate, Rolnick said. 14. Set a timer and walk for five to 10 minutes every hour. Over the course of an eight-hour day, those exercise snacks amount to 40 to 80 minutes of walking, 'even if it's just something as simple as walking fast around the office,' Rolnick said. Studies have shown that 60 to 75 minutes of moderate-intensity physical activity daily can lower the risk of premature death associated with lots of time sitting, he added.

Questions and expectations swirl as Monarez steps into director's role at CDC
Federal agencies Vaccines Chronic diseases Disability issuesFacebookTweetLink Follow Dr. Susan Monarez will be sworn in as director of the US Centers for Disease Control and Prevention on Thursday, and she's taking the reins at a perilous time for the agency. The CDC has lost nearly a quarter of its staff since January, thanks to massive workforce cuts at federal health agencies. The Trump administration's proposed budget for the fiscal year 2026 would slash the agency's funding by more than half. And under a proposed reorganization, the agency stands to lose more of its programs: Some are set to be moved to a new Administration for a Healthy America while others, such as the National Center for Chronic Disease and Health Promotion, would be eliminated altogether. All this is playing out as US Health and Human Services Secretary Robert F. Kennedy Jr., who has long promoted misinformation about vaccines, has moved to undermine longstanding federal policies and processes that support vaccination in the United States. Kennedy has also throttled communications coming out of federal health agencies, including the CDC, all but silencing its scientists amid the worst measles outbreak in the US in three decades. Many at the agency and in the wider public health world are wondering whether Monarez will prove to be a savior or a sycophant. Morale among agency staff is bleak, according to one CDC official who spoke on the condition that they not be named for fear of reprisals. Staffers are feeling unsure about what Monarez's confirmation means, the official said. Many see her as a good scientist and someone with experience in leadership positions at federal agencies. But they also wonder whether she'll be constrained by Kennedy, the official said. Monarez's tenure in government spans Republican and Democratic administrations. Before coming to the CDC in January, she was deputy director for the Advance Research Projects Agency for Health, or ARPA-H, and was founding director of the Center for Innovation at the Health Resources and Services Administration. She held other leadership positions at the Department of Homeland Security and the Biomedical Advanced Research and Development Authority. In her confirmation hearing, Monarez described herself as the daughter of a dairy farmer from rural Wisconsin who attended state schools and paid her own way through college, eventually earning a Ph.D. in microbiology and immunology. She said that her research was focused on two diseases, African sleeping sickness and toxoplasmosis, and that she was drawn to public health because treatments for those diseases remain limited but public health interventions have reduced the impact of the diseases. Under questioning by senators, Monarez seemed to distance herself from Kennedy on two issues: vaccines and fluoride. In response to questions from Sen. Bernie Sanders, an independent from Vermont, about the US ending its support for the Global Alliance for Vaccines and Immunization, Monarez said, 'I think vaccines save lives. I think that we need to continue to support the promotion and utilization of vaccines.' When Sanders asked whether she agrees that there is no scientific proven link between vaccines and autism, Monarez said, 'I have not seen a causal link between vaccines and autism.' Regarding fluoride, Monarez told Sen. Angela Alsobrooks that she considered it 'an important component to oral health. … The direct application can be very valuable.' Alsobrooks asked about fluoridation of public drinking water, including in Monarez's own town. 'They have fluoridation there. Is it safe for families, the water in Potomac, Maryland?' 'I believe the water in Potomac, Maryland, is safe,' Monarez answered. One staffer who worked under Monarez at ARPA-H described her as a quiet presence. She wasn't the type of manager who is an active presence on Slack or email, they said. 'We all respected her. She's been in government a long time,' said the staffer, who spoke on the condition that they not be named for fear of retaliation. Dr. Jennifer Nuzzo, who directs the Pandemic Center at Brown University's School of Public Health, has known Monarez for at least a decade. 'She's a lifelong government scientist who has risen through the ranks to become a very senior leader,' Nuzzo said. 'She's loyal to serving the American people.' They worked together when Monarez was detailed to the White House, where she worked on the US National Action Plan for Combating Antibiotic-Resistant Bacteria. 'She got into the nitty-gritty of a complex policy issue, but she was also able to bring together a really diverse set of stakeholders to provide input into that strategy,' Nuzzo said. 'I think that's a great example of what Susan does.' Monarez has said she has three priorities for the CDC. First, she said, she wants to improve trust in the agency and its recommendations. Next, she will focus on strengthening public health infrastructure by investing in tools to prevent, detect and respond to threats in near real-time. She pledged to collaborate with state and local public health departments to build a nationwide public health network. Finally, she said, she will work to create rapid, evidence-based responses to public health emergencies, with timely communication that is consistent and grounded in facts. While these are worthy goals, Nuzzo said, her biggest worry is whether Monarez will be able to act independently, without political interference. 'You can't run an organization as important and large as the CDC if you need to get permission for everything that needs to be done,' Nuzzo added. Dr. Richard Besser, a former acting director of the CDC, said in a statement that he looked forward to meeting Monarez to better understand her plans to lead the agency. Besser is now president and CEO of the Robert Wood Johnson Foundation. 'Dr. Monarez must not only lead the CDC – she must fight for it. Our nation's entire public health system depends on CDC having the tools it needs to respond to pandemics, reduce chronic disease, and address health inequities that continue to leave too many communities behind. That starts with a director willing to speak the truth, defend science, and stand up for the health of every American,' Besser said.
