(NEW YORK) — Two people have died in Pennsylvania from measles, the state health department said Tuesday. Both were unvaccinated.
These the first deaths related to measles within the state in 35 years, according to the Pennsylvania Department of Health, and the first deaths reported this year in the U.S.
“My deepest sympathies are with the loved ones who are facing this unimaginable loss,” Dr. Debra Bogen, the state’s secretary of health, said in a statement. “Because measles was largely eliminated in the Commonwealth for more than three decades, people are not familiar with this disease and don’t fully understand the potential severity of the illness.”
In late July, the number of confirmed measles cases in the U.S. surpassed the total reported for all last year, according to data from the Centers for Disease Control and Prevention.
Last year’s total of 2,289 was the highest number of recorded measles cases in more than 30 years, CDC data shows. However, the 2,777 total marks the highest number of cases recorded since 1991.
The CDC currently recommends that people receive two doses of the MMR vaccine, the first at ages 12 to 15 months and the second between 4 and 6 years old. One dose is 93% effective and two doses are 97% effective against measles, the CDC says.

(NEW YORK) — Health experts tell ABC News that the current science behind the hantavirus that circulated throughout the MV Hondius does not show the same levels of transmission as with COVID-19, while acknowledging that the scenario may seem similar to the beginning of the 2020 pandemic.
“Our current understanding is that person-to-person transmission of Andes virus is relatively rare and generally associated with prolonged close contact,” the current Centers for Disease Control and Prevention public health assessment said. “There is also no documented evidence of presymptomatic transmission.”
Officials around the globe have taken major steps to prevent the spread of the hantavirus, and an American doctor who was onboard noted how conditions on the cruise ship may have helped the virus propagate.
In the U.S., the boat’s 18 American passengers have been put in quarantine in Nebraska, while more than 40 people with exposure to the sick are being monitored to see if they develop the illness.
“In the vast majority of cases it happens when people breathe in mouse secretions,” Dr. Emily Abdoler, a clinical associate professor of medicine at the University of Michigan, who specializes in infectious diseases, told ABC News.
“The Andes strain found in Chile and Argentina has the possibility of human-to-human transmission, but that’s really more really close contact. It’s not sharing the same household,” she added. “It’s more like sharing the same bed.”
Dr. Stephen Kornfeld, an American oncologist who became the ship’s de facto doctor after the Hondius’ physician contracted the virus, initially received inconclusive results with samples taken from the ship but later tested negative.
Speaking to ABC News from his quarantine on Thursday, Kornfeld noted that conditions on the ship — including ventilation and the size of rooms — could have created a “complicated” situation for transmission while observing some social casual contact.
“If you do have casual contact, you’re doing it repetitively,” he said. “There were three rooms that we would gather in many times a day, often for an hour or an hour and a half, for lectures and discussions and meals. And I can just envision lots of frequent casual contacts, and perhaps over time that adds up to something more than just a single casual contact.”
Abdoler, who helped diagnose a case of hantavirus in Michigan in 2021 — the type we have in the U.S. that does not spread between people –said the benefit that medical professionals and agencies, such as the World Health Organization, have now is that the hantavirus has been researched for over 30 years. It is not a new virus.
While the data around the Andes strain believed to have been on the boat is still limited given the rare number of cases outside of South America, Abdoler said there does not appear to be any indication that the transmission methods have changed for the Andes strain.
ABC News medical contributor and epidemiologist Dr. John Brownstein concurred, saying that previous research suggests the hantavirus is a respiratory illness. That means germs can be coughed up, he noted, but it is not an aerosol-based virus.
“It’s not like COVID or measles where it could linger in the air for some time,” he said.
Brownstein added that the incubation period for the virus is long, and despite the lower risk for person-to-person transmission, it is critical that health officials stick to their policies to isolate and monitor anyone connected to the Hondius. Isolation can then be initiated if they become a positive case.
“Incubation can be anywhere from one to eight weeks,” he noted.
During a news briefing Friday, WHO officials stressed that said there is no evidence so far that the virus has changed to become more transmissible or more severe.
Officials said transmission is believed to be based on several factors, including how infectious the patient is, the environment and whether protection and PPE was used.
On Friday, acting Centers for Disease Control and Prevention director Jay Bhattacharya told reporters no cases of hantavirus have been reported in the U.S.
There are now at least 10 cases that have been linked to the ship’s outbreak. Two passengers died from the virus and a third death has been deemed probable by WHO.
Sixteen Hondius passengers, including Kornfeld, initially were flown to the quarantine center at the University of Nebraska Medical Center and had not shown any symptoms as of early Friday. Kornfeld had been placed in a biocontainment unit at the facility.
Two other American passengers were flown to Atlanta for “assessment and care,” according to officials. They were later transferred to the quarantine unit in Nebraska on Friday.
The remainder of the passengers are in quarantine at home and are being monitored.
WHO warned more positive cases could still appear during quarantine because the virus’ incubation period is long, but said that would not necessarily mean the outbreak is growing.
Abdoler noted that the fact that there have not been as many positive cases from the ship and their contacts shows that the data about the Andes transmission is holding up and there are no signs that the virus can spread as easily as other pathogens.
She noted that he is glad that the risk is being taken seriously and that those that have been exposed are being monitored.
“My sense is that there is no really need to panic, but [WHO] is taking a very conservative approach to the outbreak and asking everyone to isolate during the intubation period,” she said.
“I think it is good they are taking a conservative approach because there are unknowns, but I am not personally altering my personal practices of travel or how I go out,” she added.

(DETROIT) — Cases of a parasitic infection are continuing to rise in at least two states, local health officials said.
As of July 6, nearly 700 cases of cyclosporiasis, an intestinal infection, were confirmed, an official from the Michigan Department of Health and Human Services (MDHHS) told ABC News on Monday. This is an increase from the roughly 300 cases reported on Thursday.
The 678 cases have predominantly been confirmed the southeast region of Michigan including Wayne County, where Detroit is located.
Typically, the state has 50 cases per year, meaning cases are currently about 13.5 times higher than on average.
Dr. Natasha Bagdasarian, an infectious disease physician, epidemiologist and the chief medical executive for the state of Michigan, described the 678 figure as a “moving target,” meaning that cases are likely to continue rising.
“There is a significant lag time between exposure to contaminated produce or contaminated materials and development of symptoms,” she told ABC News. “So it can take a week, sometimes even two weeks between exposure and development of symptoms.”
She added that there may be some infected individuals who are only now reading news reports and getting tested, so there may be even more delayed diagnoses.
Additionally, in Ohio, there were 177 cases of cyclosporiasis as of July 2, Ken Gordon, press secretary for the Ohio Department of Health’s communications office, confirmed to ABC News.
Cases have been confirmed across 43 counties in Ohio so far this year, according to Gordon. Most of those cases — 171 — were reported since June 20.
Meanwhile, the Centers for Disease Control and Prevention (CDC) reports 145 cases have been detected in 17 states since May 1, excluding Michigan, as of June 16, with at least 20 people hospitalized. No deaths have been reported.
The CDC said cases ranged between age 5 and 86, with a median age of 42, and 61% were female.
So far, no cases have been linked between states and health officials are still investigating if there is a common source of the outbreak in Michigan.
The parasite usually spreads through food or water contaminated with feces, according to the CDC.
Foodborne outbreaks of cyclosporiasis have been linked to various types of imported fresh produce, such as raspberries, basil, snow peas, mesclun lettuce and cilantro, according to the CDC. The agency further said it takes about one week from the time of infection to become symptomatic, but that time can range from two days to two weeks.
Bagdasarian said MDHHS’s working hypothesis is that the outbreak is linked to contaminated produce, but it’s unclear which produce, how long it has been on the shelf or where it’s been distributed.
“We are making sure that we’re issuing guidance to the public as well as to restaurants and commercial kitchens so that folks know the safest way to eat produce right now,” she said. “If folks are making the switch and consuming all of these products as safely as possible, that could mean that we are still seeing cases where people were exposed.”
Some patients do not experience any symptoms but, for those who do, the most common symptom is “explosive watery diarrhea,” doctors previously told ABC News. Other symptoms can include cramping, bloating, low-grade fever, nausea and vomiting, the doctors said.
Since cyclosporiasis symptoms can resemble other illnesses, it may be hard for a patient to determine what they are infected with.
While a traditional stomach bug will have symptoms that typically disappear within 24 to 48 hours, cyclosporiasis symptoms may last for days or even weeks, Bagdasarian noted.
“If you believe that you could have cyclosporiasis, it’s really important to see your healthcare provider and to mention cyclosporiasis, just in case they haven’t heard about this outbreak happening right now, and ask for stool testing, because not all stool testing routinely will include cyclosporiasis,” she said.
The CDC said the infection is very unlikely to spread from person to person because it takes at least one to two weeks outside the body for the parasite to become infectious after someone passes a bowel movement.
Local and federal authorities are working to find the cause of cases in various states and to see if there are any connections. So far none have been identified.
Cyclosporiasis is treated with the oral antibiotic trimethoprim-sulfamethoxazole (TMP-SMX), commonly sold as Bactrim, Septra and Cotrim, taken for 10 days, according to the CDC.
The CDC recommends that people can prevent infection by thoroughly washing produce, cutting away bruised or damaged parts of fruits and vegetables and refrigerating pre-prepared or pre-cut produce.
“Grabbing a scrub brush can also be helpful,” Dr. Darien Sutton, an emergency medicine physician and ABC News medical correspondent, said on “Good Morning America Weekend” on Sunday. “And an important note here, this type of parasite doesn’t easily go away with alcohol-based hand sanitizer. So, good old handwashing is really key here.”

(WASHINGTON) — The Centers for Disease Control and Prevention announced Friday that the cyclospora outbreak that plagued thousands of people across the country during the summer months has ended.
The outbreak, which was eventually tied to iceberg lettuce distributed by Taylor Farms, sickened almost 13,000 people in 21 states. Two people died and at least 570 people were hospitalized due to cyclospora illness.
The FDA announced in July that it was investigating cyclospora illnesses linked to shredded iceberg lettuce served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia after several cases of cyclospora had been reported in late June.
The CDC said Friday more than 1,000 cases were reported in a single day at the height of the outbreak, before the contaminated lettuce was recalled by Taylor Farms on July 17. The illness notably made headlines for causing “explosive diarrhea.”
Citing a decline in infections linked to the outbreak — fewer than two per day in August — and all contaminated Taylor Farms products being taken out of circulation, the CDC said it considers this specific outbreak over. It notes the best-by dates for all products linked to the outbreak have passed and are no longer available in stores or restaurants.
The FDA will continue to investigate the cause of the contamination, which has not yet been identified.
