Parvovirus or ‘slapped cheek disease’ is on the rise, CDC warns: Here’s what to know
A respiratory disease known as parvovirus B19 is on the rise in the U.S. among all age groups, according to a recent advisory from the U.S. Centers for Disease Control and Prevention (CDC).
The CDC issued the health alert on Aug. 13 after European public health authorities reported “unusually” high numbers of cases in 14 countries during the first quarter of 2024, the advisory said.
The virus typically causes a blotchy rash on the cheeks that appears as if someone has slapped them — hence its nickname, “slapped cheek disease.”

“Parvovirus can be a very mild infection in many people, but if you are pregnant or are immunocompromised in any way, you are at a much greater risk of serious illness,” Dr. Aaron Glatt, chief of infectious diseases at Mount Sinai South Nassau Hospital on Long Island, New York, told Fox News Digital.
What is parvovirus B19?
Parvovirus B19 is a virus that can be easily spread by respiratory droplets in the air after an infected person coughs or sneezes, according to the CDC.
Children are often infected at school and spread it to other kids through close personal contact, then later to adults when they come home, experts say.
Approximately 50% of people who were not previously infected contract the virus from an infected family member — while 20% to 50% of susceptible students and staff become infected during school outbreaks, the advisory notes.
“The virus is highly contagious and can spread asymptomatically,” Dr. Marc Siegel, senior medical analyst for Fox News and clinical professor of medicine at NYU Langone Medical Center, told Fox News Digital.

Parvovirus B12 is also known as “fifth disease” because it was previously listed fifth on a list of common childhood viral illnesses that cause rashes, according to Mayo Clinic.
(The top three on this list are measles, rubella and scarlet fever.)
Symptoms of the virus
Many people who get infected don’t have symptoms, but some will experience sickness, according to the advisory.
About a week after an exposure, susceptible children may complain of flu-like symptoms, including fever, muscle pain and fatigue, which generally last less than a week.
People are most contagious in this early phase of the illness.
Several days after the fever starts, children often develop the hallmark blotchy “slapped cheek” rash — a helpful clue that health care providers use to diagnose the illness.
People are generally not infectious by the time they develop the rash, experts say.
A fine, “lacy” rash may follow on the chest, back, buttocks, or arms and legs that is sometimes itchy, according to the CDC. It usually goes away in about a week to 10 days.

Adults are less likely to develop the “slapped cheek” rash. Their most common symptoms are a generalized rash on the body and joint pain that affects the hands, feet and knees.
In some cases, adults only experience joint pain, which usually lasts one to three weeks – although it can last for months. It usually resolves without long-term complications.
Antibodies provide immunity
Antibodies from prior infection help prevent recurrence of parvovirus B12, the CDC said.
“Once infected, you have a lifetime immunity,” Siegel noted.
The largest increase in infections was among children ages 5 to 9.
Most adults in the United States are immune — with 50% having detectable antibody levels by age 20, and more than 70% acquiring them by age 40, per the advisory.

The share of people who have had a recent infection dropped below 3% between 2022 and 2024, but increased to 10% in June of this year.
The largest increase in infections was among children ages 5 to 9, going from 15% to 40% in that time frame, the health alert noted.
People who work in settings with close contact with children, such as schools and day cares, are at a greater risk of infection.
High-risk populations
Most healthy adults and children only have a mild illness, but people with weakened immune systems, pregnant women and those with chronic blood disorders can develop serious health complications from this virus, according to the CDC.
“Anyone with those conditions should be very quick to seek out medical attention to help address potential complications,” Glatt noted.
Pregnant women who are susceptible to the virus may spread the illness to their babies, the CDC warned.
“Unfortunately, there is an increased risk of miscarriage if you get parvovirus during pregnancy,” Glatt said.
Parvovirus infection may lead to adverse outcomes — such as severe anemia in the fetus and miscarriage — in 5% to 10% of cases during pregnancy, with the highest risk at between 9 and 20 weeks of fetal gestation, per the advisory.
“There is an increased risk of complications in patients with significant immunocompromising conditions, such as those who have leukemia, have received an organ transplant or have an HIV infection,” Glatt added.
Since most adults are immune to the virus, however, many pregnant women are protected from the virus, the CDC noted.
Treatment is mainly ‘supportive care’
Infected pregnant women primarily receive supportive care, which means treating the underlying symptoms and monitoring for severe fetal anemia, according to the advisory.

People with weakened immune systems or those with chronic blood disorders can sometimes develop bone marrow failure as a result of the virus, the advisory added.
In that case, treatment often includes blood cell transfusions and intravenous immunoglobulin (IVIG).
(IVIG is a collection of antibodies that strengthens the immune system, according to Mayo Clinic’s website.)
There is currently no vaccine to prevent parvovirus B19, and most people infected with the virus will recover without any long-term complications.

“While there is no specific treatment for parvovirus infection, recognizing the complications and addressing them early may be of benefit,” Glatt added.
Hand-washing can also help to prevent transmission, according to Siegel.

Words and game of Scrabble keep married couple in wedded bliss for decades
A married couple who have long enjoyed the game of Scrabble both together and separately before they even met are never at a loss for words — and attribute their wedded bliss in part to their love of the nostalgic game.
They’re still playing in tournaments built around the game decades after they began doing so.
Graham Harding and his wife Helen Harding, both in their 60s, have been married for over 20 years.
WATCHING GAME SHOWS LIKE ‘JEOPARDY!’ AND ‘WHEEL OF FORTUNE’ CAN BOOST COGNITIVE HEALTH, SAY EXPERTS
They met in the 1990s at Scrabble tournaments, as news agency SWNS reported.
But it was a “special match” in 2000 that brought the couple together — and has kept them together now.
Graham Harding is from the East Berkshire Scrabble Club, while his wife Helen is from the Leicester Scrabble Club in the U.K.
They have been taking part in the UK Open Scrabble Championship in Reading this week.
“The more words you know, the more ammunition you’ve got.”
“Scrabble is all about having a good vocabulary,” said Graham Harding, SWNS noted.

“But it is a Scrabble vocabulary — not necessarily everyday English.”
Added Helen Harding, “The more words you know, the more ammunition you’ve got.”
The couple said they were “vague acquaintances” for about five years after they first met.
Then they got together after a special match in Swindon.

They maintained a long-distance relationship before they got married in 2004.
The couple even brought their Scrabble board to their wedding.
It featured a message with Scrabble pieces that said, “Congratulations on your wedding day” — while their wedding cake said, in Scrabble letters, “Helen and Graham.”

They each took up the hobby early in life well before they met each other.
The tournament that’s been taking place this week is the first since the COVID pandemic after a five-year break — and the couple has played some two dozen games in it as of Friday, SWNS reported.

Deep sleep can keep two big health problems at bay, new studies suggest
It might be worth working a little bit harder to get that much-desired, but often elusive, good night’s sleep.
Deep sleep clears the mind of waste just as a “dishwasher” cleans dirty plates and glasses, just-published research suggests — and there’s more.
The findings also offer insights into how sleeping pills may disrupt the “brainwashing” system — potentially affecting cognitive function for people over the long run.
ANOTHER REASON TO GET MORE SLEEP AND THIS ONE MIGHT SURPRISE YOU
Study senior author professor Maiken Nedergaard of the University of Rochester and the University of Copenhagen said norepinephrine (a neurotransmitter and hormone) triggers blood vessels to contract — generating slow pulsations that create a rhythmic flow in the surrounding fluid to carry away waste, news agency SWNS noted.
Said Nedergaard, “It’s like turning on the dishwasher before you go to bed and waking up with a clean brain. . . . We’re essentially asking what drives this process and trying to define restorative sleep based on” this “glymphatic clearance.”
The brain has a built-in waste removal process – the glymphatic system – that circulates fluid in the brain and spinal cord to clear out waste, according to the scientists.
The process helps remove toxic proteins that form sticky plaques linked to neurological disorders, such as Alzheimer’s disease.
But the scientists indicated that what drives the system was unclear until now, according to the study.
Is all sleep created equal? The researchers wanted to find out.
To find clues, Nedergaard and her team looked into what happens in mice when their brains sleep, as SWNS reported of the study. The team focused on the relationship between norepinephrine and blood flow during deep sleep.

They found that norepinephrine waves correlate to variations in brain blood volume — suggesting that norepinephrine triggers a rhythmic pulsation in the blood vessels. The researchers then compared the changes in blood volume to brain fluid flow.
The brain fluid flow fluctuates in correspondence to blood volume changes, suggesting the vessels act as pumps to propel the surrounding brain fluid to flush out waste.
Natalie Hauglund of the University of Copenhagen and the University of Oxford, the study’s lead author, said, “You can view norepinephrine as [the] conductor of an orchestra.”
She added, “There’s a harmony in the constriction and dilation of the arteries, which then drives the cerebrospinal fluid through the brain to remove the waste products.”
‘I CAN’T SLEEP BECAUSE OF RACING THOUGHTS AT NIGHT — HOW CAN I STOP THEM?’: ASK A DOCTOR
Hauglund said she wanted to understand whether all sleep is created equal.
To find out, the research team administered zolpidem, a common drug to aid sleep, to mice.
“If people aren’t getting the full benefits of sleep, they should be aware of that, so they can make informed decisions.”
They found that the norepinephrine waves during deep sleep were 50% lower in zolpidem-treated mice than in naturally sleeping mice.
Although the zolpidem-treated mice fell asleep more quickly — fluid transport into the brain dropped more than 30%, as SWNS reported.
The researchers say their findings, published in the journal Cell, suggest that the sleeping aid may disrupt the norepinephrine-driven waste clearance during sleep.
Hauglund said, “More and more people are using sleep medication, and it’s really important to know if that’s healthy sleep. If people aren’t getting the full benefits of sleep, they should be aware of that, so they can make informed decisions.”

The research team said the findings likely apply to humans, who also have a glymphatic system, although it requires further testing.
Nedergaard added, “Now we know norepinephrine is driving the cleaning of the brain, we may figure out how to get people a long and restorative sleep.”

Meanwhile, a lack of sleep may be doing more damage than just making people groggy.
It could be sabotaging the brain’s ability to keep intrusive thoughts at bay.
Another new study, this one published in the Proceedings of the National Academy of Sciences, found that sleep deprivation weakens the brain’s defense against unwanted memories, allowing them to flood the mind, according to the New York Post.
“We show that sleep deprivation disrupts prefrontal inhibition of memory retrieval, and that the overnight restoration of this inhibitory mechanism is associated with time spent in rapid eye movement (REM) sleep,” the scientists said.
