(NEW YORK) — Respiratory illness activity – a measure of how often conditions like the common cold, flu, COVID-19, and respiratory syncytial virus are diagnosed – is currently “high” in the United States, according to an update from the Centers for Disease Control and Prevention.
Currently, New Hampshire is listed as having “very high” respiratory virus activity, and 11 states – Arizona, Delaware, Georgia, Idaho, Kansas, Kentucky, Louisiana, Oklahoma, Tennessee, Texas and Wisconsin – are listed as having “high” activity, CDC data shows.
Meanwhile, 29 states are listed as having “moderate” activity, and the remaining states are listed as having “low” activity.
Particularly, COVID-19, seasonal flu and RSV activity are increasing across the country with a rising number of people visiting emergency departments and the number of tests coming back positive for one of the three conditions, the CDC said.
The CDC estimates that there have been at least 3.1 million illnesses, 37,000 hospitalizations and 1,500 deaths from flu so far this season; these figures are based on the latest date for which data is available, which is the week ending Dec. 21.
Five pediatric deaths were reported during the week of Dec. 21, bringing the total number to nine so far during the 2024-25 season.
The CDC says levels of the COVID-19 virus being detected in wastewater are increasing, as are the number of emergency department visits and laboratory test positivity rates.
“Based on CDC modeled estimates of epidemic growth, we predict COVID-19 illness will continue to increase in the coming weeks as it usually does in the winter,” the CDC said in a statement.
For RSV, the CDC said emergency department visits and hospitalizations are increasing among children and hospitalizations are increasing among older adults in some areas.
Flu and COVID-19 vaccines are available for both children and adults, and RSV vaccines are available for certain groups of adults. However, vaccination coverage remains low, meaning “many children and adults lack protection from respiratory virus infections provided by vaccines,” according to the CDC.
As of Dec. 21, only 41.9% of adults were vaccinated against the flu and 21.4% were vaccinated with the updated 2024-25 COVID-19 vaccine. Additionally, just 43.7% of adults ages 75 and older have received the RSV vaccine, according to CDC data.
Nearly half of all children are vaccinated against the flu at 42.5%, but just 10.3% have received the updated COVID-19 vaccine.
More than 90 norovirus outbreaks were reported during the week of Dec. 5, the most recent week for which data is available, according to the CDC.
CDC data from previous years for the same December week show a maximum of 65 outbreaks reported.
National CDC data reflects what has been reported in state and counties across the country.
In Minnesota, more than 40 outbreaks were reported in December, almost twice the usual number, according to the state Department of Health.
Earlier this month, an event celebrating the top restaurants in Los Angeles left at least 80 people sickened with norovirus, which was linked to raw oysters, the county’s Department of Public Health confirmed to ABC News.
Norovirus is a highly contagious virus that is the most common cause of viral gastroenteritis, which is an inflammation of the inside lining of the gastrointestinal tract.
Although it’s often referred to as the “stomach bug” or “stomach flu,” norovirus illness is not related to influenza.
The most common symptoms are nausea, vomiting, stomach pain and diarrhea. Patients, however, can also experience fever, headaches and body aches.
According to the federal health agency, every year the virus causes between 19 and 21 million illnesses, 109,000 hospitalizations and 900 deaths.
A person can become infected by having direct contact with someone who is infected and sharing food or utensils with them; touching surfaces or objects contaminated with norovirus and then touching their face or mouth; or consuming contaminated foods or liquids.
Typically, an infected person will develop symptoms between 12 to 48 hours after being infected. However, norovirus typically resolves quickly and, in most healthy adults, lasts one to three days, according to the CDC.
There is no specific medication or antiviral for norovirus, meaning the only treatment available is managing symptoms.
The CDC recommends staying hydrated and drinking liquids that replenish electrolytes, which can be depleted through diarrhea and vomiting.
Although symptoms will resolve in a few days for most people, certain groups are at high risk for severe dehydration including those under age 1, the elderly and the immunocompromised.
Health experts say the best way to prevent getting norovirus is to wash hands with warm soap and water for 20 seconds. Hand sanitizer does not work well against norovirus.
The CDC says people should wash their hands after using the toilet or changing diapers as well as when eating, preparing or handling food.
To prevent contamination from food, make sure fruits and vegetables are washed, and that shellfish is cooked to at least an internal temperature of 145 F.
(NEW YORK) — Women are now being diagnosed with cancer more often than men in certain age groups, according to a new report from the American Cancer Society.
Among adults aged 50-64, cancer rates are slightly higher in women, and women under 50 are almost twice as likely as men in the same age group to receive a cancer diagnosis.
The report, released Thursday, found that while deaths continue to decrease, troubling racial disparities persist, with white Americans more likely to survive cancer than other groups.
Meanwhile, the report echoed data from recent years suggesting a worrying increase in cancer diagnosis among younger Americans, with colon cancer rates increasing among adults 65 and younger.
Broadly, the report suggested doctors are getting better at saving lives thanks to better treatments but reinforced worrying trends around rising diagnoses of some cancers, particularly among women. Changes in screening practices, lifestyle factors, obesity, environmental hazards and lower rates of smoking in men may be contributing to the trend, the report said.
Alcohol in particular was singled out as a possible lifestyle factor that may increase the risk of some cancers.
“For colorectal cancer, for example, it seems to be really excessive [alcohol intake] that is associated with increased risk of this cancer, whereas for breast cancer, there doesn’t seem to be any safe level of alcohol, but the elevated risk is small,” said Rebecca Seigel, senior scientific director of cancer surveillance research for the American Cancer Society.
As Seigel explained, higher rates of cancer in young people could also be part of a “generational impact” where people are diagnosed earlier in life and less frequently when they are older.
Lung cancer remains particularly deadly, with 2.5 times more deaths than colorectal and pancreatic cancer. Smoking continues to be the leading preventable cause of lung cancer, but other contributors, such as radon, air pollution and genetic mutations, may be driving cases.
“Overall, in this country, nonsmoking lung cancer, by itself, would be the eighth leading cause of cancer mortality, and worldwide, it would be the fifth leading,” said Dr. William Dahut, the American Cancer Society’s chief science officer.
Disparity rates in cancer outcomes remain striking as well, especially for minority populations.
Uterine corpus cancer, for example, has lower survival rates now than 40 years ago, with Black women at 63% survival compared to 84% for white women. Black men and women also face some of the highest death rates for prostate and breast cancers.
“I think the stubborn resistance in terms of outcomes among underrepresented minorities is a concern,” said Dr. Wayne A. I. Frederick, interim chief executive officer of the American Cancer Society.
“We have our VOICES program, which is an attempt to enroll as many African American women from across the country in a longitudinal study, something that hasn’t been done to try to answer some of these questions as to why that persistent burden is there,” he added.
The report does include some good news. While it predicts around 1,700 deaths from cancer per day in 2025, cancer death rates have fallen by 34% since their peak in 1991, preventing nearly 4.5 million deaths over the past three decades. This progress is largely attributed to declines in smoking, earlier detection for certain cancers, and advances in treatment, including breakthrough therapies like immunotherapy and targeted drugs.
Prevention has been a critical focus too, with initiatives like smoking cessation programs and HPV vaccination playing pivotal roles in reducing cancer risk. Public health efforts targeting obesity, alcohol use and expanding access to screenings have also helped tackle preventable cancers by improving early detection.
Cancer experts stress the importance of staying current with screening recommendations. For example, the American Cancer Society recommends most people start screening for colorectal cancer at age 45 or even sooner if you have a family history. For breast cancer, mammogram screening should start at age 40 for women with normal risk and earlier for women at high risk.
The report is a call for people to understand their family history better and take steps to reduce cancer risk, Dahut noted.
“Being proactive on your diet, on your exercise, avoiding tobacco, getting your vaccinations and monitoring alcohol are really all important ways to actually prevent cancer,” he said, adding that research efforts are also focused on finding new ways to detect cancer.

(NEW YORK) — As world leaders mourn the death of former President Jimmy Carter and remark on his political and policy legacy, doctors are remembering his efforts to prevent disease, and his legacy in furthering global public health.
The 39th president spent five decades working to eradicate a parasitic disease, helped organize a major-drug donation program, and made advancements addressing the mental health crisis in the U.S.
Dr. Julie Jacobson, currently a managing partner of the nonprofit Bridges to Development, helped to provide funding for the Carter Center’s work in the Americas, Nigeria and Ethiopia while she worked for the Bill & Melinda Gates Foundation for over a decade.
“He was hugely influential, I think particularly for the diseases that most of the world doesn’t appreciate even exist,” Jacobson told ABC News of Jimmy Carter’s work. “He was a true champion for the neglected tropical diseases, which are some of the most common infections of people who live with the least resources. And he found these diseases and then really wanted to do something about them, and used his voice, his influence, his passion, to continue to push forward where others were really not interested.”
Near-eradication of Guinea worm disease
Following his loss to Ronald Reagan in the 1980 presidential election, Carter founded the Carter Center in 1982, a non-profit organization that “seeks to prevent and resolve conflicts, enhance freedom and democracy, and improve health,” according to the Center’s website.
Among the organization’s many efforts, the Carter Center helped spearhead a successful international campaign with the goal of eradicating dracunculiasis, also known as Guinea worm disease, a parasitic infection caused by consuming contaminated drinking water.
Water from ponds or other stagnant bodies of water can contain tiny crustaceans commonly known as water fleas, which in turn can be infected with Guinea worm larvae, according to the Centers for Disease Control and Prevention (CDC).
About one year after infecting a human host, the Guinea worm creates a blister on the skin and emerges from it, which can cause burning pain, fever and swelling, according to the CDC and the World Health Organization.
“Nobody else wanted to take it on,” Jimmy Carter told ABC News’ George Stephanopoulos during a 2015 interview on “Good Morning America”. “So, I decided to take it on.”
In 1986, Guinea worm disease afflicted 3.5 million people every year in 21 African and Asian countries. Disease incidence has since been reduced by 99.99%, to just 14 “provisional” human cases in 2023, according to the Carter Center.
Jacobson said that success is even more remarkable because there are no vaccines available to prevent Guinea worm disease and no drugs to treat it. Tracking Guinea worm disease, according to Jacobson, involves following possible cases for a year to determine if they are infected, checking to see if infected humans have any infected water sources near them, and monitoring the community as a whole.
“To think that you could eradicate a disease without any tools is really still just a crazy idea, but he did it with perseverance and working with people in the grassroots within communities and putting together teams of people to go and work with people in those communities and empower the communities,” Jacobson said.
The Carter Center says if efforts are successful, Guinea worm disease could become the second human disease in history to be completely eradicated, after smallpox, and the first to be done without the use of a vaccine or medicine.
Carter told ABC News during the 2015 interview that eradicating the disease entirely was his goal: “I think this is going to be a great achievement for, not for me, but for the people that have been afflicted and for the entire world to see diseases like this eradicated.”
Mass drug distribution for river blindness
The Carter Center also works to fight other preventable diseases, including the parasitic infections schistosomiasis and lymphatic filariasis – more commonly known as snail fever and elephantiasis, respectively – as well as trachoma, which is one of the world’s leading causes of preventable blindness. It’s also working with the governments of Haiti and the Dominican Republic to eliminate lymphatic filariasis and malaria from the island of Hispaniola, which both countries share and which is “the last reservoir in the Caribbean for both diseases,” according to the Carter Center.
Carter and his organization also played a part in organizing a major drug-donation program to help eliminate onchocerciasis, also known as river blindness, which is transmitted to human through repeated bites of infected blackflies, according to the CDC.
Pharmaceutical company Merck & Co. had been implementing field studies in Africa which showed that the drug ivermectin was effective at treating river blindness in humans. The Carter Center partnered with Merck to mass-distribute ivermectin, brand name Mectizan, “as much as needed for as long as needed” in Africa and Latin America. To date, the Carter Center has assisted in distributing more than 500 million treatments of Mectizan, according to Merck.
In 1995, Carter negotiated a two-month cease-fire in Sudan to allow health care workers there to more safely help eradicate Guinea worm disease, prevent river blindness, and vaccinate children against polio.
“When we have known solutions, it is ethical to make sure they’re available to the people who need it most,” Dr. Usha Ramakrishnan, chair of the Department of Global Health at Emory University’s Rollins School of Public Health, told ABC News. “And that’s where we were with river blindness. There was a treatment, but improving access to medications, making it affordable, reaching the people they need was very much along the lines of the work [the Carter Center] was doing.”
Addressing mental health
Carter was also committed to tackling mental health issues. During his presidency, he created the Presidential Commission on Mental Health, which recommended a national plan to care for people with chronic mental illness.
Although it was never adopted as policy by the Reagan administration, the plan’s recommended strategies were adopted by some mental health advocacy groups to “make gains in the 1980s,” according to one study.
Carter also signed into law the Mental Health Systems Act of 1980, which provided funding to community mental health centers.
After his presidency, Carter and former first lady Rosalynn Carter continued working to improve access to mental health.
Ramakrishnan said the Carters’ work helped to reduce some of the stigma associated with mental health.
“There continues to be a lot of stigma, but they truly got it out [in] the conversation and mainstreaming mental health as an important aspect of health and well-being,” Ramakrishnan said. “There’s still a lot of challenges, and there are many capable people that they have mentored and trained who are carrying that mantle forward.”
