North Carolina -The highly contagious norovirus is a frequent gastrointestinal illness that induces vomiting and diarrhoea and it is rising once more in the United States amid the holiday season. The people who have experienced it previously are aware of how awful it can be. Although norovirus can infect anyone and spreads throughout the year, outbreaks are most frequent in the winter. According to the US Centres for Disease Control and Prevention, norovirus is the main culprit behind outbreaks of foodborne disease in the country. Doctors say should drink plenty of liquids to replace fluid lost from vomiting and diarrhea. This will help prevent dehydration. Sports drinks and other drinks without caffeine or alcohol can help.
