In October 2024, an American man returned to Iowa after traveling to Liberia, unknowingly carrying Lassa fever. His illness showed how quickly a health threat abroad can become a threat at home. Drawing on 16 years of CDC partnership in Liberia, CDC-trained disease detectives and other global health teams partnered with CDC experts to quickly provide U.S. health officials with critical guidance to help prevent its spread—protecting Americans here at home. #CrisisToControl

During the 10th annual Fungal Disease Awareness Week, @SecKennedy joined @DrSchwartzCDC, @CDCgov experts, clinicians, researchers, and patient advocates for a roundtable on mold surveillance.
The goal is clear: diagnose fungal disease sooner, improve treatment, strengthen surveillance, and protect patients and communities.

In late 2023, an unusual cluster of Guillain-Barré syndrome (GBS), a rare neurological disorder, emerged in Guatemala along a major travel corridor linking the region to the United States.
Global health security experts, including CDC-trained disease detectives, partnered with local health officials to investigate the cluster, identify Campylobacter—a bacterium that causes many foodborne illnesses—as the likely cause for the GBS cases, and stop its spread.
Within 3 months, the outbreak of Campylobacter was contained with no cross-border spread. It never reached U.S. shores. #CrisisToControl

In 2024, an estimated 14.3 million adults thought seriously about suicide. Every one of them is someone's friend, coworker, or family member. Many who have struggled with suicide or attempted suicide go on to live healthy lives, and we can all support them by encouraging help-seeking. If you're worried about someone, contact the 988 Suicide and Crisis Lifeline. 988lifeline.org/

CDC has not received through its normal channels the formal Epi-Aid request described by Reuters.
CDC will not submit to political blackmail that conditions critical public health assistance. The people of Pennsylvania should never be used as leverage in a political dispute over how deaths are classified.
Federal outbreak assistance and national mortality reporting are separate processes.
Pennsylvania may classify deaths as “measles-associated” under its state surveillance definition, but CDC is working with the Council of State and Territorial Epidemiologists to establish a standardized definition for measles deaths to ensure consistent reporting across jurisdictions. In the interim, CDC will apply the same national standard to every state and report any measles-caused deaths when the National Center for Health Statistics identifies measles as the underlying cause based on death record information submitted by the states.
CDC will not allow Governor Shapiro to politicize this process. We owe the American people accurate, consistent, and transparent public health information.
The Pennsylvania health department said it was requesting emergency support from the US CDC as it grapples with one of the country's largest and most deadly measles outbreaks, according to a document reviewed by Reuters on Thursday. reuters.com/world/pennsylvan…

In 2025, Senegal faced a deadly Crimean-Congo hemorrhagic fever outbreak, raising fears that the virus could spread beyond the Kaffrine Region. CDC-trained field epidemiologists and local response teams were among the first on the ground. They moved quickly—tracking contacts, testing human and animal samples, and containing the outbreak in just 7 days. Their rapid response stopped the outbreak from spreading—protecting local communities and keeping America safe. #CrisisToControl

CDC-trained disease detectives and laboratory professionals are responding to the #Ebola outbreak in the Democratic Republic of the Congo. Working alongside response partners, they are strengthening disease tracking, laboratory testing, infection prevention, and contact tracing to identify cases, break chains of transmission, and reduce spread.
CDC has trained 25,000+ disease detectives across 90+ countries and 12,000+ laboratory professionals across 40+ countries. Building this expertise helps countries detect threats earlier, respond faster, and stop diseases before they spread—strengthening #globalhealthsecurity and helping protect Americans.

CDC retweeted
Governor Shapiro has chosen to politicize this outbreak instead of implementing a unified public health response. He continues to point the finger at me and the federal government and to malign the Amish while refusing the federal assistance that might help end the outbreak.
I have offered the Governor CDC Epi-Aid, which would put CDC epidemiologists on the ground to help the state respond. Texas, South Carolina, Virginia, Kansas, New Mexico, and Wisconsin requested Epi-Aids and worked alongside CDC teams to help bring their outbreaks rapidly and successfully under control.
Governor Shapiro’s claim that I directed CDC to suppress Pennsylvania deaths is false. CDC is applying a consistent national standard rather than allowing politicians to decide which deaths appear in federal mortality statistics. CDC will report measles-caused deaths when the National Center for Health Statistics reports measles as the underlying cause based on death record information submitted by the states.
CDC’s MMR recommendation remains unchanged. I have repeatedly stated that MMR vaccination is the most effective way to prevent measles infection.
Pennsylvanians deserve accurate, evidence-based public health information—not political grandstanding.
Today, the Pennsylvania Department of Health confirmed two more measles-associated deaths after local coroners reported these individuals died from complications associated with measles. That's four total measles-associated deaths in our Commonwealth and the first Pennsylvania has seen in 35 years. These are tragedies, and four families are grieving.
Pennsylvania is experiencing the worst measles outbreak in the country. To date, we have 693 recorded cases of measles in 38 of our 67 counties. This disease was declared eliminated in the United States in 2000 — yet decades later, we are seeing it surge due to lower vaccination rates.
This serious situation continues to be made worse by RFK Jr. playing games with public health and safety. It's long past time for @SecKennedy to stop stoking vaccine skepticism and misinformation and compromising the serious mission of the nation’s public health agencies. It is also deeply concerning to learn that the Secretary personally intervened in an otherwise administrative process to direct the CDC to not report these Pennsylvania deaths, presumably because it doesn’t fit his phony narrative.
Measles is preventable. I continue to urge all Pennsylvanians to speak with your trusted health care provider and get the best possible information to protect yourself and your family against this deadly disease.

In November 2025, Ethiopia faced a historic first: a confirmed Marburg virus outbreak. As cases increased, CDC experts partnered with local health officials to strengthen laboratory testing, expand surveillance, and contain the virus before it could spread farther. CDC-trained disease detectives played a critical role in investigating cases, tracing contacts, and strengthening border measures at the airport. Six weeks later, the outbreak was over, 14 cases were confirmed and contained at the source, never reaching American shores. #CrisisToControl

Suicide prevention starts long before a crisis. There's no single cause of suicide, and stressors like job loss, money problems, and social isolation can all play a part. The good news: everyone can play a part in prevention, too. Need support now? Call or text 988, or chat at 988lifeline.org/

Twenty-five years ago, our nation was forever changed.
Today, we remember the nearly 3,000 lives taken on September 11, 2001, and honor the first responders who ran toward danger to save others.
In the days and weeks that followed, HHS joined the response, including the @usphscc and personnel from the National Disaster Medical System and the National Pharmaceutical Stockpile, which would later become important parts of @ASPRgov.
We honor all who served, all who sacrificed, and all who still carry the wounds of that day.
We will never forget. 🇺🇸

Most outbreaks that occur abroad never make the news. That’s because CDC and our partners are there to detect, investigate and stop them before they spread.
In the past two years, CDC-supported field epidemiologists and other global health experts helped stop more than 250 outbreaks in 40+ countries—including dengue, Marburg, hemorrhagic fevers and Guillain-Barré syndrome.
In observance of #WorldFieldEpidemiologyDay earlier this week, we’re recognizing CDC-trained disease detectives around the world who help stop outbreaks at the source—and protect Americans from health threats before they reach our shores. #CrisisToControl
