Understanding norovirus

It's a highly contagious viral infection that results in gastroenteritis, characterized by unpleasant symptoms like vomiting and diarrhea.

It spreads through direct contact with an infected person, consumption of contaminated food or water or contact with contaminated surfaces. The virus is notorious for its rapid transmission, especially in crowded environments like cruise ships.

Typically, symptoms appear 12 to 48 hours after exposure and can last for 1-3 days.

Vomiting, diarrhea, nausea, upset stomach, headaches and fever are common symptoms. Mild infections usually resolve on their own without need for medical attention.

However, certain people are more vulnerable to problems, particularly dehydration, like young children, elderly and those with underlying medical disorders.

How to prevent norovirus?

To prevent its transmission and spread, it's crucial to take preventive measures, especially in crowded places like cruise ships. These measures include:

Clean hands: Wash your hands frequently with soap and water, especially after using the restroom, changing diapers or handling food.

Avoid close contact: Stay away from people who are visibly ill to minimize the risk of catching the virus.

Safe food practices: Make sure your meals are cooked thoroughly, and wash fruits and vegetables properly before consuming. That reduces the chances of getting sick from contaminated food.

Sanitize surfaces: Regularly disinfect surfaces that could be contaminated, like countertops, tables and doorknobs, using appropriate cleaning products.
