⚠️The vomiting and diarrhoea bug Norovirus is currently spreading in the community.
Washing your hands frequently with soap and water is the best way to protect yourself.
DO NOT VISIT anyone in hospital if you are unwell with vomiting and/or diarrhoea, or if you have been caring for someone who has it, even if the symptoms are mild or abating, for at least 72 hours.
This is because the virus spreads very easily and you will still be infectious for a while after your symptoms stop.
Below is some information and advice about Norovirus:
What is Norovirus?
It's a virus that is highly infectious type of gastro-enteritis that is easily passed on to others. Like any virus, antibiotics will not cure it.
What are the symptoms of Norovirus?
Norovirus symptoms include nausea, diarrhoea and vomiting. You may also have a temperature (fever), headache and aching arms and legs.
How long does Norovirus last?
Symptoms usually start within one or two days of being infected. They can usually be managed at home and should disappear after a few days although you will remain contagious for up to 72 hours after your last symptoms.
How do you catch Norovirus?
You can catch Norovirus from eating some food items such as shellfish or other food items prepared by some who is unwell. You can also become infected from having close contact with people who have the infection.
The virus particles will settle onto surfaces when people have symptoms of vomiting and diarrhoea. If you don’t clean your hands after touching contaminated items or surfaces, and you then touch your eyes, nose or mouth, you may introduce the virus to yourself and you may become infected.
Protecting yourself and your family
Swansea Bay University Health Board infection prevention and control matron Joanne Walters is urging us to help control the spread of norovirus, which is very easily passed from person to person.
"The best way to protect yourself and your family is by washing your hands regularly with soap and water," she explained.
"Washing hands with soap and water is always the best way to clean your hands. Some alcohol gels and hand sanitisers are not effective against these viruses."
• This is especially the case after using the toilet;
• Before preparing food and drinks;
• After using a shopping trolley and other things that are commonly touched by other people;
• Before eating and drinking.
