Illustration of a shield with a vaccine vial and germ. Text reads: Vaccination is vital. Vaccines are the best protection against whooping cough. Who gets vaccinated for pertussis: Kids under 7 receive the DTaP series. Adolescents and adults need periodic Tdap boosters*. Pregnant people should get a booster during every pregnancy, as it passes protective antibodies to newborns before they can be vaccinated themselves. *Talk with your primary care doctor to learn when you need a Tdap booster.

“Vaccination was always important, but it’s even more important right now. It is the single most effective way of preventing pertussis in babies who account for 96% of whooping cough-related deaths.” Ruth Karron Professor of International Health

illustration of a medical checklist. Text reads: Another piece of the puzzle: Whooping cough outbreaks tend to be cyclical, occurring every three to five years as immunity from both vaccines and prior infections starts to decrease. Pertussis vaccination does not provide lifelong protection, but rather short-term immunity. This means it is imperative people get their vaccine and boosters when needed. “It’s a serious disease. It will roar back if we don’t immunize. It’s not like we’ve controlled it and it’s gone. We need to be vigilant; we need to continue to immunize our children, and we especially need to continue immunizing pregnant moms.” Ruth Karron

Illustration of a person coughing. Text reads: What is whooping cough? Pertussis, also called whooping cough or the 100-day cough, is a respiratory infection caused by Bordetella pertussis bacteria. Whooping cough’s early symptoms are similar to a common cold’s, which can make it hard to initially diagnose. Testing, especially after known exposure, is vital so that treatment can begin as early as possible. Pertussis is highly contagious, spreading through droplets when infected people cough or sneeze.

Illustration of a person covering their mouth with their elbow next to a box of tissues. Text reads: What are the symptoms? Early symptoms: Runny or stuffy nose; Low-grade fever (less than 100.4°F); Mild, occasional cough. One to two weeks after the first symptoms start, people may develop violent coughing fits that can last up to 10 weeks. Later symptoms: A high-pitched “whoop” when inhaling after a coughing fit; Feeling very tired; Difficulty sleeping at night; Struggling to breathe

Illustration of a person holding an infant. Text reads: Young infants are most at risk. Babies under 6 months old may not develop the characteristic “whoop” coughing sound. They may experience choking or pauses in breathing that require hospitalization. Serious complications can include pneumonia, low oxygen levels, brain injury, and heart failure. Because the risk of complications is so high, infants under 2 months old diagnosed with pertussis should immediately be hospitalized.

Illustration of two antibiotic pills. Text reads: What is the treatment? Treatment for pertussis focuses on early antibiotic therapy to reduce contagiousness and severity. Over-the-counter cough medicines are not effective at treating coughing associated with pertussis. If you are sick, stay home for five days after starting antibiotics. Severe cases may require hospitalization for oxygen and IV fluids. Continue to practice good hygiene like handwashing and covering coughs, masking, and post-exposure antibiotics for close contacts, especially infants, to limit spread and protect vulnerable populations.

Pertussis—commonly known as whooping cough—is experiencing a major resurgence in the U.S. with nearly four times as many cases as in 2023.

Vaccines are the best protection against the highly contagious respiratory infection.

Puzzle of a brain. Text reads: support children’s mental health: More than 16 million children and adolescents were diagnosed with a mental, emotional, developmental, or behavioral health condition from 2022 to 2023. While Medicaid and CHIP cover mental health services, and school-based services can improve access, more than half of kids who needed treatment had difficulty accessing care.

Child's car seat. Text reads: Protect Children from Injuries. Injuries are a leading cause of death and hospitalization among kids—but many of them are preventable. Drowning is the top cause of death for kids ages 1–4, and falls land 2.8 million kids ages 1-4 in the emergency department every year. Simple interventions, like pool fences and barriers for stairs and windows, can prevent dire consequences.

Factory smoke stack. Text reads: reduce harmful environmental exposures: Environmental contaminants have been linked to health problems including respiratory diseases, childhood cancers, neurodevelopmental disorders, obesity, and adverse birth outcomes. Kids’ smaller bodies make them more vulnerable to environmental toxins, which can have consequences during growth and development.

Piggy bank. Text reads: Expand the Child Tax Credit. A family’s economic stability is foundational to children’s health and well-being. During the pandemic, the Child Tax Credit was increased from $2,000 to $3,600—an expansion that lifted 2.1 million of America’s children out of poverty. Most families used these funds to meet basic needs, resulting in lower food insecurity.

Vaccine vial. Text reads: Preserve Vaccine Access: The CDC estimates that routine childhood vaccinations will prevent 508 million illnesses, 32 million hospitalizations, and 1.3 million deaths among U.S. kids born between 1994–2023. The Vaccines for Children Program ensures free vaccination for kids who are uninsured or underinsured.

Open umbrella. Text reads: Protect Medicaid & CHIP. Medicaid provides health care coverage for 4 in 10 U.S. children and 8 in 10 children in poverty. It is the only source of coverage for 1 in 3 children with special health care needs. Medicaid and Children’s Health Insurance Program (CHIP) cover nearly half of the nation’s children, paying for vaccinations, well-child visits, vision and hearing screenings, dental care, and more.

Raspberries, blueberries, and strawberry. Text reads: Ensure Access to Healthy Food. Nearly 1 in 5 U.S. kids live in a food-insecure household, which harms their physical and mental health, cognitive function, and school performance. Programs like SNAP, WIC, and free and reduced-price school meals help kids get the nutrition they need and improve their health—in childhood and beyond.

Safe. Text reads: Prevent Firearm Deaths. In 2023, firearms were the leading cause of death for children ages 1–17, taking more lives than car crashes, overdoses, or cancer. Policy solutions include Child Access Prevention laws, which ensure safe, secure storage, and Extreme Risk Protection Orders, which can temporarily restrict access to firearms by people at risk of harming themselves and others.

Graphic of a drop of blood with a warning label. Text reads: Emergency Blood Shortage. The Red Cross’ national blood supply has fallen by more than 35% over the past month. Explaining the current crisis (and how you can help!)

Graphic of two medical professionals standing in front of an empty storage container. Text reads: Why is there a shortage? Hospitals already strained by the worst flu season in nearly 20 years are now also being forced to triage critical blood products. High flu activity in nearly every state may be sidelining donors, slowing efforts to rebuild the Red Cross national blood supply. Intense winter weather and freezing temperatures impacted about 400 blood drives just last month. As a result, thousands of blood donations have gone uncollected. Donors in areas unaffected by weather are vital in ensuring access to lifesaving care across the country.

Graphic of a person donating blood. Text reads: What makes blood donations important? Blood can only be made available through volunteer donors. Without immediate action, patients who rely on transfusions — including trauma victims, mothers in childbirth, and people with sickle cell disease or cancer — face serious risk. When supplies are critically low, trauma surgeons and doctors face the possibility that blood could run out when needed most. It’s the donated blood AVAILABLE NOW that helps during emergencies.

Graphic of a person donating blood. Text reads: How you can help: Make an appointment to give blood. Learn more about who can donate. Share this post to spread the word. To donate, use the Red Cross Blood Donor App, visit RedCrossBlood.org or call 1-800-RED CROSS (1-800-733-2767). Blood donation is now more inclusive. More people are able to donate blood with the American Red Cross through updated FDA guidelines that eliminate eligibility questions based on sexual orientation.
