Unique Symptoms Of Norovirus In 2025 And How Long Does The Infection Last?

Recently the news of Norovirus outbreak in an AIDA cruise that has infected more than 100 guests and crew on board made news. This is the 21st outbreak, as confirmed by the Centers for Disease Control and Prevention (CDC). This case has brought back memories from the Royal Caribbean Cruise outbreak, where 94 out of 1,874 and 4 crew members also were infected by Norovirus. 

This virus is also known as the 'rib-cracking' winter virus, which sets it apart from rest of the winter viruses. People who have been sickened by this contagious virus are vomiting explosively, which may make the sufferers to experience a cracking in their ribs, which is where it gets its name 'rib-cracking' winter virus. 

<h2>What Is Norovirus? What Makes It So Unique?</h2>

The virus typically spikes after the holidays, when families gather indoors. However, new data from the Centers for CDC shows this year’s surge has arrived weeks ahead of schedule, and experts say there’s no obvious explanation yet.

According to the CDC, 12.5 percent of norovirus tests came back positive during the week of November 22, nearly identical to the 13 percent positivity rate the week before. Compared to two weeks earlier, infections have jumped by about 25 percent. But the real number of cases is likely far higher, as most people with norovirus never get tested.

Between August 1 and November 13, health officials recorded 153 norovirus outbreaks, more than double last year’s 69 during the same period, and far above the 65 reported in 2023.

The CDC estimates the U.S. sees around 2,500 outbreaks every year. An outbreak is recorded when two or more people fall ill from a suspected or confirmed shared source.

On cruise ships, which are closely monitored by federal agencies, outbreaks have also been climbing. The AIDAdiva, a German vessel currently on a long global route, recently reported a spike in cases. In a statement to USA TODAY, AIDA Cruises said it has increased hygiene measures on board and that infections are already declining.

“Seasonal illness peaks between November and April, and the AIDAdiva report reflects what we’re seeing on land,” the cruise line said.

Norovirus infects roughly 21 million Americans every year and sends about 2 million to hospitals or clinics. It spreads easily through contaminated food, surfaces, shared utensils, or direct contact with an infected person. Even a tiny amount of virus can trigger illness.

Symptoms usually appear within 12 to 48 hours and include nausea, vomiting, diarrhea, stomach cramps, and sometimes fever and chills. The biggest danger is dehydration, which can set in quickly. Severe fluid loss can lead to low blood pressure, reduced organ perfusion, electrolyte imbalances, and in extreme cases, seizures or fainting.

The virus contributes to about 900 deaths in the U.S. annually, mostly among older adults.

Doctors emphasize that hand sanitizers don’t reliably kill norovirus. Frequent handwashing with soap and water is the best protection.

The season’s lowest positivity rate was recorded in early August at 6.5 percent. But with holiday travel and gatherings underway, health officials warn infections are likely to rise.

The symptoms usually begin 12 to 48 hours after your first exposure to the virus and could last from 1 to 3 days. You can, however, continue to shed virus in your stool for several week after your recovery. The shedding could go up for months if you have another medical condition.
