A surge in norovirus cases is prompting hospital officials to issue urgent warnings, urging the public to restrict hospital visits to prevent further spread.
What is norovirus?
Norovirus is a viral infection that inflames your intestines, which is why many of the symptoms relate to tummy pain.
For many people, the illness is relatively mild and clears up after one to three days.
But norovirus can cause young children, older people and those with compromised immune systems or underlying conditions to become severely dehydrated.
In extremely rare cases, people sickened with norovirus require hospital treatment.
Symptoms of norovirus: Nausea, Vomiting, Diarrhoea, High temperature, Headaches, Exhaustion
Spread: Norovirus is highly contagious, with fewer than 100 particles enough to cause illness.
