Norovirus hits cruise ship in San Francisco; Here's what makes it dangerous, and how to stay safe
Mail This Article
A cruise ship docked in San Francisco has been hit by the highly contagious norovirus. Coming on the heels of the spread of hantavirus on a cruise to Argentina in May this year and some ships in Finland and France reporting similar noro hits, the incident has sparked concerns among travellers worldwide.
In San Francisco, the stomach virus has hit several among the 120 passengers and crew members on a Princess Cruises ship that docked on Thursday. Named the Ruby Princess, the cruiser was on a 20-day round-trip journey from San Francisco to Canada and Alaska when 102 passengers and 23 crew members were stricken by the virus, said the US Centres for Disease Control and Prevention (CDC).
What is norovirus?
Norovirus is highly contagious and often spreads through contaminated food or surfaces, particularly in crowded settings. It is a short-lived illness for many people, but can be dangerous for people with underlying health conditions, young children and those aged 65 and older.
How does norovirus spread?
Most norovirus outbreaks occur when people who are already infected spread the virus to others through direct contact, such as sharing food or utensils. Outbreaks can also be spread through food, water or contaminated surfaces.
Symptoms of norovirus
a) Sudden onset of vomiting
b) Diarrhoea
c) Stomach pain that can last three days
The ship will be thoroughly cleaned and disinfected before departing on its next trip, the company said. So far this year, there have been seven illness outbreaks reported on cruise ships within the CDC's jurisdiction, mostly due to norovirus, health officials said.
Norovirus: Preventive methods
Washing hands frequently is key to preventing a norovirus infection, especially after using the bathroom or before eating and drinking. It is best to use soap and water, scrubbing and washing for at least 20 seconds. Hand sanitiser alone doesn't work well against norovirus, the CDC said.
