Norovirus or food poisoning: How to tell the difference. ”Norovirus and food poisoning are easy to confuse as the symptoms are almost identical, including severe nausea, diarrhoea, stomach cramps and vomiting…” says Niamh McMillan, Superdrug's Pharmacy Superintendent. ”Norovirus is the most common type of virus which causes gastroenteritis, an inflammation of the stomach and intestines. Norovirus is also referred to as the 'winter vomiting bug' due to its prevalence during the colder months, however, it can be caught at any time of the year.” The expert goes on to explain that food poisoning occurs when the digestive system is infected. ”Food poisoning is caused by eating food that has been contaminated by harmful bacteria, parasites or viruses which then irritates and infects your digestive system.” Niamh notes that symptoms of norovirus can take between eight and 12 days to appear and can include persistent vomiting, diarrhoea and in some cases, headaches and dizziness. Meanwhile, the effects of food poisoning are often felt within two to six hours and additional symptoms include aches, chills, fever and loss of appetite. While you can't always avoid norovirus or food poisoning, there are a few things you can do to minimise your chances. Wash your hands thoroughly Washing your hands throughout the day will help you avoid catching bad germs. ”Don't underestimate the benefit of washing your hands thoroughly with antibacterial soap, for at least 20 seconds.” “This is particularly important if you've been in public areas, for example, on public transport or if you've touched high traffic surfaces such as door handles, lift buttons and railings.” Food safety To avoid food poisoning, it is important to store and cook your food properly and practice good hygiene. ”This includes making sure all food, in particular meat, is cooked thoroughly, Using a thermometer can be a helpful way to ensure food is cooked to a high enough temperature in order to kill harmful bacteria.” Keep your distance If you know someone who might have norovirus, you should stay away from them as it is contagious. ”Norovirus can be transmitted by coming into contact with someone suffering from the virus, contaminated surfaces and also food and water so try and keep areas around you clean and disinfected.” "A person suffering from norovirus is most contagious from the moment they start feeling (ill) to at least three days after recovery.”
