Norovirus cases hit 10-year high as cruise travel spikes this summer

BREVARD COUNTY, Florida. – The norovirus is making a comeback on cruises. The CDC has been tracking the highest number of “stomach bug” cases in more than a decade, and relaxed hygiene could be to blame.

Millions of people are flocking to cruise terminals around the world, and increased traffic means there’s a higher chance of passengers getting sick on and off the ship.

“Norovirus is common in settings where people are clustered together,” said Dr Timothy Laird, associate chief medical officer of the Health First medical group.

So far this year, there have been 13 norovirus outbreaks on numerous cruise lines, including Royal Caribbean International, Viking, Princess and others, according to CDC data. In six months, the current outbreaks already exceed all of 2022.

“He just had to stay in the cabin for 48 hours, and they brought him food,” said Stewart Chiron, known as “The Cruise Guy” and industry expert.

Chiron has been on more than 300 cruises and her son had the virus on board. He has also seen ships in code red, which means many passengers and crew are sick.

“When you went to the restaurant, they took away the bread and the salt and pepper shakers, and the crew members will do that for you,” he added. “If you go up to the buffet, you won’t be able to help yourself.”

If food is contaminated with feces, the virus spreads, so washing your hands often — for at least 20 seconds — is your best protection.

“The other problem with Norovirus is that it’s not easily killed with alcohol,” Laird said when adding hand sanitizer isn’t your best option.

31.5 million people are expected to sail in 2023, 106% more than in 2019, according to the Cruise Lines International Association.

“People travel with a vengeance, and I can tell you it’s like their Mack trucks. Nothing’s going to stop them,” Chiron added.

Catching the virus could slow you down and quarantine you on vacation. Doctors say on board fruit that you need to peel is a safer option, and make sure leafy greens and other vegetables are washed thoroughly.

“Unfortunately, your cruise is over at this point. You remain in your cabin until you are better,” Laird concluded.

Dr Laird says most people will fight off the virus on their own in around 24 to 48 hours, but infants, the elderly and people with kidney disease are at high risk. They might not be able to rehydrate and might need to see a doctor.
