Virus symptoms sweeping Britain after ‘don’t go to work’ warning.

The UK’s Health Safety Agency has issued an alert after thousands of norovirus cases – 75% more than would normally be found at this time of year. The agency said anyone who catches it should stay home in an attempt to stop the spread.

Amy Douglas, Norovirus epidemiologist at UKHSA said: “Norovirus levels were higher in April than we would normally see at this time of year and they have been increasing. This is probably due to a combination of factors, but the colder weather we’ve had hasn’t helped.

“Norovirus can cause dehydration, particularly in vulnerable groups such as young children and older or immunosuppressed people, so if you do get sick it’s important to drink plenty of fluids. If you have diarrhea and vomiting, you can take steps to avoid spreading the infection. Do not return to work, school or daycare until 48 hours after your symptoms have stopped, and do not prepare food for others during that time either.”

Norovirus is a highly contagious virus that causes gastroenteritis, which is an inflammation of the stomach and intestines. Symptoms of norovirus usually include:

1. Nausea : A feeling of discomfort in the stomach which may be accompanied by the urge to vomit.

2. Vomiting : Often sudden and profuse, vomiting is a common and prominent symptom.

3. Diarrhea : Watery and often frequent bowel movements are a hallmark of norovirus infection.

4. Stomach cramps : Abdominal pain or cramping may occur and range from mild to severe.

5. Little fever : Some people may experience a slight fever.

6. Muscle pain : Generalized body aches or muscle aches may occur, although these are uncommon.

7. Fatigue : The infection can lead to a general feeling of weakness and fatigue.

8. Headache : Some people may have a headache during the infection.

Symptoms usually develop 12 to 48 hours after exposure to the virus and usually last 1 to 3 days. In some cases, especially in young children, older adults, and people with weakened immune systems, symptoms may be more severe and last longer.

Norovirus is highly contagious and spreads easily through contaminated food, water, surfaces and close contact with infected people. Good hygiene practices, such as frequent hand washing and proper food handling, are crucial in preventing the spread of norovirus.
