Did you know that the norovirus is one of the most common stomach bugs? Norovirus; also known as the winter bug; is a common bug which causes sickness and diarrhoea. Its suggested that you take 48 hours out of work/school to stop spreading the bug. The sickness bug can be spread through contact with an infected person, touching contaminated surfaces or food. The bug normally only lasts 2/3 days but it is important to make sure you stay hydrated as you lose a lot of fluids. You also lose a lot of energy so keep well rested.
