Norovirus Hits Princess Cruise Ship; US CDC Reports 5th Stomach Bug Outbreak of 2026

The US Centers for Disease Control and Prevention (<span>CDC</span>) has reported another <span>norovirus outbreak</span> aboard a Cruise ship that has sickened nearly 125 people.

So far this year, the CDC has reported seven outbreaks on cruise ships under its jurisdiction, five of which were caused by norovirus.

The outbreak occurred aboard the <span>Ruby Princess</span> during a 20-day voyage along the west coast of North America.

According to the CDC, 102 passengers and 23 crew members reported gastrointestinal illness during the voyage.

The outbreak was first reported to the CDC's Vessel Sanitation Program on June 28.

The Ruby Princess was carrying more than 3,000 passengers and 1,144 crew members during the outbreak.

According to the CDC, Princess Cruises and the ship's crew implemented increased cleaning and disinfection procedures under the company's outbreak prevention and response plan.

Crew members also collected stool specimens from affected individuals for testing, isolated ill passengers and crew members, and consulted with the CDC's Vessel Sanitation Program.

Norovirus is a highly contagious virus that causes gastroenteritis, leading to inflammation of the stomach and intestines.

Speaking to <strong><em>HealthandMe</em></strong>, epidemiologist Dr. Amitav <span>Banerjee</span>, professor at DY Patil Vidyapeeth, Pune, described norovirus as “notorious because it spreads very fast.”

“It can spread through fomites like handles and knobs, and even a very low infectious dose—around 18 viral particles—can cause infection. So it spreads very fast,” he said.

He added that while many common disinfectants are ineffective against it, norovirus can be inactivated using bleach and chlorine-based cleaning agents.

<h2>Is The Norovirus Outbreak Of Concern?</h2>

Although outbreaks can look alarming, Dr. Banerjee emphasized that norovirus infections are generally self-limiting.

“In the ship, it can be managed with oral rehydration, and in severe cases, IV fluids can help prevent complications and mortality,” he said.

Dr. Banerjee also clarified that, unlike diseases with pandemic potential, norovirus outbreaks—while explosive in nature—do not typically pose a long-term global threat.

"Norovirus is a stomach infection contracted through the consumption of contaminated food or water or through contact with an infected individual. The infection is highly contagious, but not life-threatening, and is manageable with proper care and hydration," Dr Suresh Kumar D, Senior Specialist - Infectious Diseases, Apollo Speciality Hospitals, Vanagaram, Chennai, told <strong><em>HealthandMe</em></strong>.

<h2>Who Is Most at Risk? What Are The Key Symptoms</h2>

Dr. Banerjee noted that extreme age groups, especially very young infants and the elderly, are at higher risk due to dehydration from diarrheal illness. However, deaths remain rare when proper care is provided.

Norovirus illnesses usually last between two and three days. Symptoms usually begin suddenly within 12 to 48 hours of exposure and may include:

<ul><li>Nausea</li><li>Vomiting</li><li>Watery diarrhea</li><li>Stomach cramps</li><li>Low-grade fever</li><li>Headache and body aches</li><li>Fatigue</li></ul>Most people recover within 1–3 days, but dehydration can become serious, especially in children, elderly individuals, and those with weak immunity.

<h2>What You Can Do To Stop Its Spread</h2>

Because of how fast viruses spread, experts highly recommend preventive actions such as:

<ul><li>Wash your hands frequently with soap and warm water, especially after using the toilet or before preparing food.</li><li>Avoid visiting hospitals or care homes if experiencing symptoms.</li><li>Stay home for at least 48 hours after symptoms subside to prevent spreading the virus.</li></ul>
