The UK Health Security Agency (UKHSA) is urging people with certain symptoms to "stay home for 48 hours" as a nasty virus spreads.
Norovirus is highly infectious, but there are measures you can take to safeguard yourself and your family if someone in your household becomes sick.
The NHS states that norovirus can spread through close contact with an infected person, touching surfaces or objects contaminated by the virus and then touching your mouth.
Food that has been prepared or handled by a person who is ill can also harbour the virus. And unlike with some other illnesses, alcohol-based hand gels do not kill the norovirus bacteria.
The UKHSA said in a new alert on X, formerly Twitter: "Norovirus spreads easily, so if you catch it you should stay home for 48 hours after symptoms stop."
The agency further advises: "Washing your hands regularly with soap and warm water can help you stop catching it and passing it on if you do get sick.
"If you catch norovirus don't go to work or school for 48 hours after symptoms stop, as you can still pass it on during this time. Do not visit loved ones in hospital or care homes in this time to avoid causing outbreaks."
Norovirus can typically be managed at home by ensuring the patient gets plenty rest and stays hydrated to prevent dehydration.
People usually start to recover within two to three days. However, if your vomit begins to resemble ground coffee, contains blood, or takes on a green or yellow-green hue, it's crucial to seek immediate medical attention.
