Winter is the season for Norovirus! Norovirus is a virus that’s the most common cause of “stomach flu”, or gastroenteritis. It strikes fast; those with it come down with vomiting, diarrhea, abdominal cramping. About 1 in 5 adults get gastroenteritis every year; nearly everyone has it at some point in their lifetimes.
With Norovirus going around yet another year, test your Norovirus IQ with these 6 Facts or Myths:
#1. Fact or myth: You can get Norovorius from touching a doorknob.
Fact. You can get Norovirus from touching something that a person with the virus touched. That includes doorknobs, but also anything else that organisms can live on: computer keyboards, coffeemakers, faucets, etc. That’s why it’s so important to wash your hands frequently; with so many people infected with it in the winter, you can catch it easily from a colleague or family member.
#2. Fact or myth: Norovirus is the same thing as food poisoning.
Myth. This myth came about because you can get Norovirus by sharing the food or drink of someone who has it, and by eating or drinking infected food or drink. Also, Norovirus spreads very fast, especially in close quarters such as nursing homes, schools, and cruiseships—another reason why people confuse it with food poisoning. However, food poisoning is caused by a toxin found in the food, not a virus that's spread through food. No matter the label, it’s important not to share food with people who may be sick and to beware of raw or undercooked food.
#3. Fact or myth: There is a Norovirus vaccine.
Fact. There are vaccines that have been developed against Norovirus, but they aren’t very effective. That’s because the virus mutates quickly, and each season produces several new strains of the Virus. So even though vaccines exist, they are not routinely recommended to prevent Norovirus.
#4. Fact or myth: There are effective medicines that will kill Norvirus.
Myth. The bad news is that there are no effective antiviral medicines that will kill Norovirus. The good news is that Norovirus is generally a harmless and self-limiting condition. The biggest danger is that of dehydration, and symptoms are typically gone in 2-3 days without treatment. Medications such as antidiarrheals may have more risks than benefits, so resting and keeping well hydrated are the key steps to recovery.
#5. Fact or myth: Pregnant women are particular at danger if they contract Norovirus.
Myth. Studies have shown that there are no unique harms of Norovirus during pregnancy, and Norovirus does not directly affect the baby. However, the symptoms of vomiting and diarrhea can lead to dehydration and electrolyte imbalances. This can increase the likelihood of a urinary tract infection and potentially of preterm labor. For these reasons, pregnant women should take extra caution to not contract Norovirus and other illnesses.
#6. Fact or myth: There are effective ways to prevent catching Norovirus
Fact. Here are 4 ways to prevent getting Norovirus:
1) Avoid people who have symptoms of vomiting and diarrhea. Don’t share their utensils or their food or drink.
2) Wash your hands with soap and water often and well, especially if you are in close quarters with potential sick people such as hospitals, schools, daycare centers, and nursing homes.
3) Beware of raw and undercooked food. Wash salads carefully. Cook meat and seafood well.
4) Keep healthy. Eat healthy, regular meals; rest; and exercise. Build up your immune system in case you do get exposed to this or other viruses.
Norovirus is a common, but unpleasant illness. If you do get it, make sure to drink plenty of fluids and get good rest. You may need to see your doctor if you can’t keep down fluids, have high fevers, or experience severe pain. Make sure your doctor listens to you and gives you a diagnosis—and explains to you what to do. As with anything else, prevention is the best medicine.
