Timely outbreak news, health alerts, advisories, case updates, and exposure guidance.
If you may have been exposed to Andes virus through the 2026 U.S. cruise-ship outbreak and you develop fever or breathing symptoms, contact a clinician and public health promptly. CDC and WHO interim guidance explains the monitoring window after exposure, common symptom patterns, and how labs use coordinated testing—when different tests are most useful.
After a measles exposure at daycare/school, timing matters. MMR works best within 72 hours of the first exposure. Immune globulin may be an option within 6 days for people who can’t safely get MMR—so call a clinician and follow local public health instructions right away.
If you ate requesón or soft ricotta-style cheese tied to a June 2026 Listeria investigation, check whether it’s part of the Clover Hill Dairy recall and monitor for symptoms. Symptoms often begin in about 2 weeks, but can start as early as the same day or as late as 10 weeks—so timing matters, especially for pregnant people, older adults, and immunocompromised people.
After rodent urine, droppings, or nesting material exposure, hantavirus illness can start like flu or stomach upset and then worsen. Here’s when to seek testing—and when to treat breathing trouble as an emergency.
FDA says all currently marketed lots of Nara Organics Whole Milk Organic Powdered Infant Formula are recalled after a three-case infant botulism outbreak. Here is what families can do now, which symptoms need urgent care, and what officials still do not know.
CDC’s Health Alert Network update explains when clinicians should consider testing for possible Andes virus—a rare hantavirus—including the key idea that testing depends on symptoms plus the exposure history, not exposure alone. Here’s what evaluation may involve and when to seek urgent care.
Probably yes—especially if anyone in your household will travel internationally, has an unclear MMR record, or may be due for a routine dose. With measles still spreading in the United States, checking vaccine records now can help families avoid last-minute surprises before summer trips.
If you have recalled Nara Organics formula at home, stop using it, set aside any opened can, clean feeding items, and watch your baby for symptoms for one month after the last use.
CDC and FDA officials say parents should stop using recalled Nara Organics infant formula, watch exposed babies for botulism symptoms for a month, and get urgent care if an infant develops feeding trouble, weakness, or breathing problems.
CDC and FDA say to stop using recalled Nara Organics infant formula, watch for infant botulism symptoms for one month after the last use, and get urgent care if a baby seems weak, floppy, or has trouble feeding or swallowing.
Most families should still follow the routine MMR schedule, but some infants, children, and adults in outbreak settings may need an earlier or extra dose. Here is the clearest way to tell when it is worth calling your clinician or local health department.
CDC’s measles tracker reported 2,030 confirmed U.S. cases as of June 4, 2026. That does not mean everyone needs an extra MMR shot, but some infants, travelers, students, healthcare workers, and adults in outbreak settings may need an earlier or second dose.
CDC’s May 29, 2026 update says 1,983 confirmed U.S. measles cases had been reported as of May 28. Here is when parents should ask about an early MMR dose, what it changes, and what it does not. ([cdc.gov](https://www.cdc.gov/measles/data-research/index.html))
CDC says the risk to the general U.S. public is low, but cruise passengers, traced contacts, and anyone with a known close exposure should watch for symptoms and act quickly if they get sick.
CDC says the risk to the American public remains extremely low, but exposed passengers are being monitored because Andes virus can spread between people in rare situations. Here’s what happened, what symptoms matter, and when to seek care.
The CDC says the public risk from the cruise ship hantavirus outbreak is very low, but a small group of exposed travelers is being monitored for up to 42 days. Here’s what Andes virus is, how it spreads, which symptoms matter, and what exposed passengers and families should do next.
A rare hantavirus outbreak tied to a cruise ship is drawing attention to rodent-borne illness, but U.S. health officials say the broader public risk remains low. For most readers, the main takeaway is practical: know the symptoms, avoid rodent exposure, and seek care quickly if breathing problems develop after a possible exposure.
CDC says emergency room visits for tick bites are running higher than usual in many parts of the country, a reminder to use repellent, check for ticks after time outdoors, and remove attached ticks quickly. The agency says people should watch for rash or fever in the days and weeks after a bite.
CDC says U.S. measles cases in 2026 have already reached a new high, and most confirmed infections are tied to outbreaks. Here’s how measles spreads, what early symptoms look like, how long exposure can matter, and what MMR vaccination and post-exposure steps can do.
U.S. measles activity remains elevated, and public health officials say the disease is still spreading in outbreaks in multiple states. For readers, the practical takeaway is simple: know the early symptoms, check vaccination status, and act quickly after a known exposure. Measles is highly contagious, and the first signs can look like a routine viral illness before the rash appears. If you think you were exposed, call ahead before visiting a clinic or emergency department so staff can reduce the chance of exposing others.
Measles is climbing again in 2026, and the most useful response for families is simple: know the signs, check vaccination status, and follow local public-health guidance after exposure. The outbreak is active, but it remains preventable with timely vaccination and fast action when symptoms appear.
CDC says U.S. measles activity is still ongoing, and the main risk is not random exposure but close contact in places where vaccination rates are low. Families, schools, child care sites, shelters, and workplaces can reduce risk by checking immunity, acting quickly after exposure, and watching for early symptoms.
