Whooping cough cases are rising again in the US

Whooping cough cases are rising, and doctors are bracing for yet another tough year.

There have been 8,485 cases reported in 2025, according to preliminary data from the U.S. Centers for Disease Control and Prevention. That’s twice as many cases as this time last year, based on the CDC's final tally.

Rates of whooping cough, or pertussis, soared last year, which experts said wasn’t unexpected. The number of cases fell during COVID-19 because of masking and social distancing. Plus, experts said, the illness peaks every two to five years.

But experts say the outbreaks of vaccine-preventable illnesses, like measles and whooping cough, could be indicative of changing attitudes toward vaccines. U.S. kindergarten vaccination rates fell last year, and the number of children with vaccine exemptions hit an all-time high.

“There’s unfortunately been increasing anti-vaccine sentiment in the United States,” said Dr. Ericka Hayes at the Children’s Hospital of Philadelphia. “Our recovery is not nearly as quick as we expected it to be and we needed it to be. And again, when you fall below 95% for vaccinations, you lose that herd immunity protection.”

Whooping cough tends to peak around this time of year and in the fall. It's usually spread through respiratory droplets in the air, when people with pertussis cough, sneeze or breathe close to others. The symptoms are similar to a cold but the cough becomes increasingly severe with a distinctive sound — a “whoop” as the person tries to take in air. It is treated with antibiotics.

In the past six months, two babies in Louisiana and a 5-year-old in Washington state have died from whooping cough.

The pertussis vaccine, which also protects against diphtheria and tetanus, is given at two months, four months and six months. The CDC recommends adults get follow-up doses every 10 years.

The illness is most dangerous for infants, especially before they receive their first round of vaccinations. That’s why the vaccine is also recommended for expecting mothers — it can protect newborns. But not enough people are getting the vaccine during pregnancy, said Hayes, who is the hospital's senior medical director of infection prevention and control.

“The uptake of the vaccine for pregnant mothers is not where we need to be at all," she said.

Pennsylvania, one of the states hit hardest by the illness last year, has recorded 207 whooping cough cases in 2025.

Neil Ruhland, a state health department spokesman, said the biggest increases are in populated areas like Philadelphia and Pittsburgh and in middle and high schools and colleges. He said 94.6% of the state's kindergarteners are vaccinated.

Michigan is on track for a similar pertussis season to last year's, said Dr. Natasha Bagdasarian, the state's chief medical executive. The state has recorded 516 cases thus far, mostly among children aged 5 to 17, and saw a total of 2,081 cases in 2024.

Bagdasarian said vaccination rates vary from county to county. Some schools have rates as low as 30%, creating pockets of vulnerable communities to vaccine-preventable diseases like pertussis and measles, she said.

“We’re watching pertussis numbers very carefully, but a lot of our resources are going into contact tracing our measles cases right now,” she said. “And public health is doing much more with fewer resources in 2025 than we’ve had to do before."

TRENTON, N.J. (AP) — Richard “Dick” Codey, a former acting governor of New Jersey and the longest serving legislator in the state's history, died Sunday. He was 79.

Codey’s wife, Mary Jo Codey, confirmed her husband’s death to The Associated Press.

“Gov. Richard J. Codey passed away peacefully this morning at home, surrounded by family, after a brief illness,” Codey's family wrote in a Facebook post on Codey's official page.

"Our family has lost a beloved husband, father and grandfather -- and New Jersey lost a remarkable public servant who touched the lives of all who knew him," the family said.

Known for his feisty, regular-guy persona, Codey was a staunch advocate of mental health awareness and care issues. The Democrat also championed legislation to ban smoking from indoor areas and sought more money for stem cell research.

Codey, the son of a northern New Jersey funeral home owner, entered the state Assembly in 1974 and served there until he was elected to the state Senate in 1982. He served as Senate president from 2002 to 2010.

Codey first served as acting governor for a brief time in 2002, after Christine Todd Whitman’s resignation to join President George W. Bush’s administration. He held the post again for 14 months after Gov. Jim McGreevey resigned in 2004.

At that time, New Jersey law mandated that the Senate president assume the governor’s role if a vacancy occurred, and that person would serve until the next election.

Codey routinely drew strong praise from residents in polls, and he gave serious consideration to seeking the Democratic nomination for governor in 2005. But he ultimately chose not to run when party leaders opted to back wealthy Wall Street executive Jon Corzine, who went on to win the office.

Codey would again become acting governor after Corzine was incapacitated in April 2007 due to serious injuries he suffered in a car accident. He held the post for nearly a month before Corzine resumed his duties.

After leaving the governor’s office, Codey returned to the Senate and also published a memoir that detailed his decades of public service, along with stories about his personal and family life.

“He lived his life with humility, compassion and a deep sense of responsibility to others,” his family wrote. “He made friends as easily with Presidents as he did with strangers in all-night diners.”

Codey and his wife often spoke candidly about her past struggles with postpartum depression, and that led to controversy in early 2005, when a talk radio host jokingly criticized Mary Jo and her mental health on the air.

Codey, who was at the radio station for something else, confronted the host and said he told him that he wished he could “take him outside.” But the host claimed Codey actually threatened to “take him out,” which Codey denied.

His wife told The Associated Press that Codey was willing to support her speaking out about postpartum depression, even if it cost him elected office.

“He was a really, really good guy,” Mary Jo Codey said. “He said, ‘If you want to do it, I don’t care if I get elected again.’”
