Norovirus sickens over 200 cruise ship passengers on month-long voyage
More than 200 cruise ship passengers were infected with norovirus on a transatlantic voyage that is currently still at sea.
The illnesses occurred on the Cunard cruise line ship Queen Mary 2, which departed Southampton in the U.K. on March 8.
The ship traveled to New York and to several islands in the Eastern Caribbean, according to Cunard’s website.

Out of the total 2,538 passengers, 224 became ill with the virus. Seventeen crew members were also affected, as stated in an alert from the Centers for Disease Control and Prevention.

Diarrhea and vomiting were the primary symptoms reported. All sick passengers have been isolated, the announcement noted.
The ship is expected to return to Southampton on Sunday, April 6.
Cunard has increased its cleaning and disinfection procedures in response to the outbreak, according to the CDC.

The cruise line has also collected stool specimens from sick passengers for testing.
“VSP (Vessel Sanitation Program) is remotely monitoring the situation, including review of the ship’s outbreak response and sanitation procedures,” the CDC stated.
Norovirus spread and symptoms
Norovirus, also known as food poisoning or the stomach bug, is a highly contagious virus that causes inflammation of the stomach or intestines, per the CDC.
“Norovirus, also known as Norwalk-like virus, is a leading cause of gastroenteritis in the U.S.,” Dr. Amber Charoen, a board-certified gastroenterologist with Gastro Health in Kennewick, Washington, previously told Fox News Digital.
“The combination of indoor spaces, close contact and crowding is why norovirus thrives in environments like schools, day cares and cruise ships,” one expert said. (iStock)
“It can spread with as few as 10 particles through contaminated food, vomit, stool and even person-to-person contact.”
The highly contagious virus can also spread via contaminated surfaces, utensils or foods.
“The combination of indoor spaces, close contact and crowding is why norovirus thrives in environments like schools, day cares and cruise ships,” Chad D. Neilsen, MPH, director of Infection Prevention and Control at Nemours Children’s Health in Florida, previously told Fox News Digital.

“Once an outbreak starts, it’s challenging to control it without public health and sanitation expertise.”
While it is often referred to as a “stomach flu” or “stomach bug,” norovirus is not related to influenza.
“Symptoms of norovirus vary, but those infected tend to have a mix of low-grade fever, chills, vomiting, headache, muscle aches and fatigue,” Baum said.
“In addition, norovirus outbreaks typically produce nausea (more often in children), watery diarrhea (more often in adults) and stomach cramps.”

There is no specific medicine to treat norovirus, according to Baum.
Nielsen previously shared with Fox News Digital that norovirus is the leading cause of foodborne illnesses in the U.S., causing about 20 million cases each year.

Norovirus is responsible for about 109,000 hospitalizations and 900 deaths each year in the U.S., mostly affecting adults over 65 years old, according to the National Foundation for Infectious Diseases (NFID).
About one in 15 Americans will get norovirus annually, and one out of 160 children will be hospitalized.
Prevention and treatment
The best defense against norovirus is to wash hands frequently, identify symptoms early and isolate if sick, according to Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst.
The CDC also recommends washing fruits and vegetables thoroughly and washing laundry in hot water, if possible.

“There is no treatment except to stay well-hydrated,” he told Fox News Digital. “[It] generally lasts around three days.”
Neilsen agreed that most people will recover from norovirus in one to three days without any treatment, but others could experience more severe symptoms like dehydration, which “could require medical attention.”

The CDC recommends drinking plenty of liquids to prevent dehydration and to seek medical care if it becomes severe.

Heart disease threat projected to climb sharply for key demographic
NEWYou can now listen to Fox News articles!
A new report by the American Heart Association (AHA) included some troubling predictions for the future of women’s health.
The forecast, published in the journal Circulation on Wednesday, projected increases in various comorbidities in American females by 2050.
More than 59% of women were predicted to have high blood pressure, up from less than 49% currently.
The review also projected that more than 25% of women will have diabetes, compared to about 15% today, and more than 61% will have obesity, compared to 44% currently.
As a result of these risk factors, the prevalence of cardiovascular disease and stroke is expected to rise to 14.4% from 10.7%.

Not all trends were negative, as unhealthy cholesterol prevalence is expected to drop to about 22% from more than 42% today, the report stated.

Dr. Elizabeth Klodas, a cardiologist and founder of Step One Foods in Minnesota, commented on these “jarring findings.”
“The fact that on our current trajectory, cardiometabolic disease is projected to explode in women within one generation should be a huge wake-up call,” she told Fox News Digital.
NEARLY 90% OF AMERICANS AT RISK OF SILENT DISEASE — HERE’S WHAT TO KNOW
“Hypertension, diabetes, obesity — these are all major risk factors for heart disease, and we are already seeing what those risks are driving. Heart disease is the No. 1 killer of women, eclipsing all other causes of death, including breast cancer.”

Klodas warned that heart disease starts early, progresses “stealthily,” and can present “out of the blue in devastating ways.”
The AHA published another study on Thursday revealing one million hospitalizations, showing that heart attack deaths are climbing among adults below the age of 55.
The more alarming finding, according to Klodas, is that young women were found more likely to die after their first heart attack than men of the same age.

“This is all especially tragic since heart disease is almost entirely preventable,” she said. “The earlier you start, the better.”
Children can show early evidence of plaque deposition in their arteries, which can be reversed through lifestyle changes if “undertaken early enough and aggressively enough,” according to the expert.

Klodas suggested that rising heart conditions are associated with traditional risk factors, like smoking, high blood pressure, high cholesterol, diabetes, obesity and a sedentary lifestyle.

Doctors are also seeing higher rates of preeclampsia, or high blood pressure during pregnancy, as well as gestational diabetes. Klodas noted that these are sex-specific risk factors that don’t typically contribute to complications until after menopause.
The best way to protect a healthy heart is to “do the basics,” Klodas recommended, including the following lifestyle habits.

Klodas especially emphasized making improvements to diet, as the food people eat affects “every single risk factor that the AHA’s report highlights.”
“High blood pressure, high blood sugar, high cholesterol, excess weight – these are all conditions that are driven in part or in whole by food,” she said. “We eat multiple times every single day, which means what we eat has profound cumulative effects over time.”
“Even a small improvement in dietary intake, when maintained, can have a massive positive impact on health,” a doctor said. (iStock)

The doctor also recommends changing out a few snacks per day for healthier choices, which has been proven to “yield medication-level cholesterol reductions” in a month.

“Keep up that small change and, over the course of a year, you could also lose 20 pounds and reduce your sodium intake enough to avoid blood pressure-lowering medications,” Klodas added.
“Women should not view the AHA report as inevitable. We have power over our health destinies. We just need to use it.”
