‘Winter vomiting disease’ is rapidly spreading – here’s how to protect yourself

(1)
Doctors warn that winter is peak season for illnesses to spread, mainly because people spend more time indoors and close together. This year, the highly contagious norovirus—often called the “winter vomiting bug”—is spreading quickly across the US and UK.

(2)
Reports show that cases have doubled in some regions, prompting health experts to urge caution during holiday gatherings. Norovirus is known for causing stomach and intestinal issues and is responsible for the majority of foodborne sicknesses in America.

The CDC explains that norovirus leads to acute gastroenteritis, an inflammation of the digestive system. While symptoms mainly affect the stomach, such as severe pain and vomiting, additional issues like headaches, fever, and body aches are also common.

(4)
People usually become ill 12–48 hours after contact with the virus, which spreads through infected vomit or stool. Most recover within 1–3 days, but vulnerable individuals can face life-threatening complications. In the US, the virus contributes to about 900 deaths and over 100,000 hospitalizations each year.

(5)
Norovirus can continue to spread for up to two weeks after symptoms stop. It’s commonly transmitted through direct contact, contaminated food or water, or touching infected surfaces and then the mouth.

(6)
There is no specific medication for norovirus, so doctors recommend staying hydrated. Preventive steps include washing hands with soap for at least 20 seconds, especially after using the bathroom, before cooking, or when giving medication. Hand sanitizers do not reliably kill the virus.

If infected, individuals should stay home and avoid others for at least two days after symptoms end. Shared spaces must be cleaned thoroughly, gloves should be used during cleaning, and laundry should be washed in hot water. Recovery mainly involves rest and maintaining fluid intake.
