The best time to prepare for a hurricane? Before there’s one on the way. Even without a named storm coming your way, there are measures you can take to keep yourself and your family safe. For more information on severe weather safety, visit ready.gov.

Be Prepared for Hurricane and Tropical Storm Season. When a hurricane or tropical storm forms, meteorologists can reasonably predict when and where it may hit, giving you time to prepare. Knowing what to expect and how to prepare can help keep you and your loved ones safe.

be prepared: Have an Emergency Plan. Identify the safest room in your home. Know your evacuation route. Pack an emergency supplies kit. Plan where to stay if you need to evacuate. Know where to get updates and emergency alerts. Protect Your Home. Secure windows and doors with storm shutters or plywood. Bring in outdoor furniture and secure loose items. Trim trees and clear gutters to minimize damage.

Follow alerts and evacuate when you're told to. If You Cannot Evacuate: Stay inside. Keep away from all windows, skylights, and glass doors. Listen for storm updates via radio, phone, or TV. Never leave shelter until it is confirmed that the storm has completely passed. The eye of the storm creates a brief, misleading calm while strong winds are still approaching.

When Flooding Occurs: Move to higher ground. Never attempt to swim or walk through floodwater. Avoid driving into areas covered with water. Avoid using bridges over fast-moving water. If you must walk through a flooded area, wear rubber boots or waders to avoid contact with floodwater. Floodwater is dangerous due to its depth and what it may contain, including: High leves of fecal contamination. chemicals, or hazardous waste. Snakes, rodents, or other animals. Downed power lines, which can electrically charge the water. Debris and other physical objects.

from the sun ... Anne Hathaway style

Anne Hathaway in the sun with a UV wet suit on, a wide-brimmed hat, and sunglasses. Text reads: Step One: UPF Clothing. Wear protective clothing such as a long-sleeved shirt and pants. Look for clothing with a UV protection factor (UPF) or made of a tightly woven fabric. If you’re swimming, surfing, or spending time near the water, wear UV-protective swimwear or a wetsuit. Water reflects sunlight, which means your skin may be exposed to more UV radiation than you think.

Anne Hathaway wearing sunglasses. Text reads: Step two: 100% UV Protection Sunglasses. When shopping for sunglasses, look for lenses that provide 100% UV protection. Labels stating “UV absorption up to 400nm” are also effective. Oversize sunglasses offer the largest shield from sun damage. Wraparound sunglasses offer even more protection by preventing UV rays from entering from the sides. Polarized lenses reduce the glare reflected from surfaces such as water or roads. Polarization itself does not provide UV protection.

Anne Hathaway in the sun with a UV wet suit on, a wide-brimmed hat, and sunglasses. Text reads: Step Three: Wide-Brimmed Hats. When choosing a hat, wear one with a wide brim to protect your ears, head, and neck. Avoid baseball caps and straw hats with open weaves or holes. They do not provide as much protection outdoors. And don’t forget the most important accessory: Sunscreen! Apply SPF 30 or higher every two hours while outdoors to protect your skin from sun damage.

SYMPTOMS can include: Severe diarrhea, abdominal cramping, bloating, nausea, fatigue, and weight loss. Cyclosporiasis is rarely life-threatening, but can be very disruptive. Spread: U.S. outbreaks are commonly associated with imported fresh produce, including bagged salads, leafy greens, fresh basil, fresh cilantro, and raspberries. No specific food source has been identified or recalled as of this date. Unlike some other stomach bugs, cyclosporiasis is not transmitted through direct contact with e.g., an infected household member.

As state health departments, the CDC, and the FDA work to identify the source, here are some precautionary measures to take. You can reduce your risk by: Limiting foods linked to these outbreaks, like leafy greens and bagged salads, fresh herbs like basil and cilantro, raspberries, snow peas, and green onions. Washing hands with soap and water before and after handling or preparing raw fruits and vegetables. Washing all fruits and vegetables thoroughly under running water before eating, cutting, or cooking them. And when in doubt, cooking eliminates it. Cooked vegetables are a safer choice. Source: CDC

Collaboration among schools, healthcare providers, public health agencies, and community organizations can help address the complex factors that keep students out of the classroom.

Sign that says "Beware of Ticks!" Text reads: The ticks are HEADED NORTH ... and to other new places. Lyme disease is most prevalent in New England, the Mid-Atlantic, the Midwest near the Great Lakes, and parts of California. But, tick populations are expanding, as milder winters and warmer springs allow them to survive in new areas and farther north, including in Canada. Harsh winters contribute too. Heavier snowfall can have an igloo effect, insulating ticks from the cold and helping them survive winter. Changes in biodiversity have also led to exploding populations of key tick hosts, like deer and the white-footed mouse. ... And more people are living in forested areas, making them more susceptible to ticks.

Noah Kahan with OFF bug spray. Text reads: YOUR NEEDS, MY NEEDS When outdoors in tick-prone areas: Wear long pants, long sleeves, and closed-toe shoes. Tuck your pants into your socks. Spray your clothes and gear with 0.5% permethrin (which kills ticks). Apply DEET on you to prevent bites.

Noah Kahan holding a dog. Text reads: DENY, DENY, DENY Ticks and tick bites. After being outside: Shake out your clothing outside or put your clothes in the dryer for 10 minutes on high heat. Bathe or shower within two hours. Do a full body check on yourself and your loved ones. If you have a dog, check them for ticks as well. Even if your dog is on a tick preventative, ticks can still hitch a ride and then crawl onto you!

Don’t have FALSE CONFIDENCE. Know what to do if you do find a tick on your body or think you’ve been bitten: DO promptly remove it. DON’T panic. Not all ticks carry disease. If they do, it generally takes 36–48 hours after a bite for them to transmit disease. Lyme disease typically causes a telltale “bullseye” rash around the tick bite—but not always. Tickborne diseases can typically be treated if caught early. So, DO see a doctor if you suspect you may have been bitten by a tick—especially if you experience flu-like symptoms.

Johns Hopkins Bloomberg School of Public Health@johnshopkinssph· May 29

Noah Kahan’s new album is everywhere this spring — and so are ticks, not just in the usual spots like Vermont. Tickborne diseases are on the rise and showing up in more places. Here's what you need to know to create a Great Divide between you and these disease-carrying bugs.

Swipe for more about this tick season. *Thanks Noah Kahan for this forever useful pun.

Noah Kahan. Text reads: MAINE Character energy: Emergency department visits for tick bites in April were more than 25% higher than in April 2025. Lyme disease is by far the most common tickborne illness. It can lead to chronic symptoms like fatigue, pain, and cognitive issues. But, other tickborne illnesses are also on the rise.

COME OVER So we can talk about tickborne illnesses. Babesiosis is a disease caused by the Babesia parasite, which infects red blood cells and can cause anemia. It can be life-threatening for people who are immunocompromised. Because it can be transferred through blood, donated blood is now tested for Babesia. Alpha-gal syndrome can trigger an allergy to mammal products like red meat and dairy.

Noah Kahan. Text reads: HOME SICK? Tickborne illnesses can cause a range of notoriously nonspecific symptoms, making them hard to diagnose. The most common are flu-like symptoms: Fatigue, Headache, Body aches, Skin rash, Fever, Joint pain. If you develop symptoms after removing a tick (even days or weeks later), consult your doctor as soon as possible and let them know about your tick encounter.

The importance of Maternal & Child Health. Around the world, mothers strive to keep their children healthy and safe, protect their well-being, and set them up for a healthy and secure future.

What is Maternal and Child Health (MCH)? Maternal and child health refers to the health and well-being of mothers and children before, during, and after pregnancy, focusing on: Access to quality health care services. Maintaining mental, physical, and emotional well-being across the life course. Prevention of disease, particularly for low-income and at-risk populations. When people can access quality care, it leads to safer births, healthier babies, and stronger starts to life.

Between 2000 and 2023, global maternal mortality dropped nearly 40%—progress that is attributed to increased access to essential maternal health services. Strong maternal and child health systems strengthen families, reduce health disparities, and improve the overall well-being and economic stability of communities. MCH looks at factors to improve pregnancy and birth outcomes, but also issues throughout the life course, like: proper nutrition, breastfeeding, mental health, and early childhood experiences.

About the Center: The Johns Hopkins Bloomberg School of Public Health’s Center of Excellence in Maternal and Child Health works hard every day to create a future where all families can access the necessary resources and services to thrive. The Center is dedicated to training the next generation of leaders in MCH research and practice by providing coursework, support, and training for students working to improve outcomes for parents and children. Along with courses, the Center supports field placements where students apply what they’re learning in real-world organizations. Help ensure every mother can receive the care and support they need.

The WHO has stressed that the risk of hantavirus infection to the public is low. “This is not the next Covid, but it is a serious infectious disease. Most people will never be exposed to this,” says Maria Van Kerkhove, the WHO’s chief of Epidemic and Pandemic Preparedness and Prevention.

WHO response: The WHO is currently working to answer many of the unanswered questions about where and how those who became ill were exposed to the virus through: Contact tracing. Looking for evidence of mice or mouse droppings aboard the cruise ship. Viral sequencing to identify the strain, vector species, and transmission routes. In South Africa: Health officials are tracing individuals who may have encountered infected cruise passengers and have identified 62 potential contacts; of those, 42 have tested negative for hantavirus. In Spain: Mónica García Gómez, Spain’s health minister, said the ship is heading to Tenerife, where passengers will be allowed to disembark. Anyone showing symptoms will be quarantined, while asymptomatic passengers from other countries will be sent home.

the only hantavirus in the Americas known to transmit between people, and not just from rodents to humans. The Andes virus is endemic to Argentina, where the cruise embarked. Transmission of the Andes virus requires very close person-to-person contact, as it spreads through respiratory droplets.

What is hantavirus? Hantaviruses are a family of viruses which can cause serious illnesses and death. They are typically transmitted from rodents to humans by breathing in contaminated air particles from rodent feces, urine, or saliva. Strains found in the U.S. and other parts of the Western Hemisphere typically cause hantavirus pulmonary syndrome, a respiratory illness with a mortality rate of about 35%. Exposure to hantavirus doesn’t always lead to illness, and many people who become sick recover with supportive care. Though infections are rare, they are often severe. Fatalities are typically among people who are older or who have underlying health conditions that are associated with more severe respiratory illness.

Prevention is crucial. While antivirals can help manage symptoms, there is no cure or vaccine for hantavirus infection. Preventing hantavirus infection involves avoiding contact with rodents and their droppings by: Sealing entry points. Storing food securely. Safely controlling infestations without disturbing contaminated materials. If cleaning potentially affected areas: Disinfect surfaces first. Wear protective gear such as gloves and a HEPA filtering mask to avoid inhaling particles. Source: CDC
