You should stay home for at least 24 hours after your last vomit, but many health authorities recommend waiting 48 hours to prevent spreading highly contagious viruses like norovirus (stomach flu) to others at work, school, or childcare, especially if you're handling food or caring for vulnerable people. Listen to your body and stay home until you feel fully recovered and symptom-free to avoid a relapse.
Diarrhoea and vomiting can spread easily
Stay off school or work until you've not been sick or had diarrhoea for at least 2 days. If you have a high temperature or do not feel well enough to do your normal activities, try to stay at home and avoid contact with other people until you feel better.
For common stomach bugs like norovirus (gastroenteritis), you should stay home and avoid spreading it for 48 hours (2 full days) after your last symptom (vomiting/diarrhea), especially if you work with food, kids, or the elderly, to ensure you're not contagious; for general symptoms, some guidelines suggest 24 hours symptom-free, but 48 hours is the safer, recommended period for infectious cases like norovirus.
Make an appointment with your doctor if: Vomiting lasts more than two days for adults, 24 hours for children under age 2 or 12 hours for infants. You've had bouts of nausea and vomiting for longer than one month.
Most people who are exposed to norovirus get sick within 12 to 24 hours. A typical illness lasts 12 to 60 hours – half a day to 2½ days. After people begin to feel healthy again, they're still contagious for a while. Many are only contagious for 48 hours; others are contagious for much longer.
The staff member should remain out of work until they have been free from vomiting and/or diarrhoea for 48 hours.
A 24-hour stomach bug, often referred to as the stomach flu, makes individuals feel unwell with a wide range of symptoms, mostly related to the gastrointestinal tract. This condition leads to inflammation of the stomach and intestines, resulting in abdominal pain, cramps, nausea, vomiting, fever, and headaches.
Avoid eating and drinking for two hours after the last episode of vomiting. Start with small amounts of clear liquids, such as water, ice, popsicles, sports drinks, clear broth or Jell-O for the first 24 hours. Avoid alcohol, caffeinated beverages, and fruit juice.
Second, just before throwing up your body produces extra saliva, which helps protect your teeth from the strong acid. Third, the vomiting process releases chemicals in your body to make you feel better. So that “I feel better” feeling after throwing up is not just your imagination — it's your biology working.
Treatment and recovery
Most people with norovirus illness get better within 1 to 3 days.
Six common signs of norovirus include sudden vomiting, watery diarrhea, stomach pain/cramps, nausea, headache, and muscle aches, often appearing 12-48 hours after exposure and lasting 1-3 days, leading to potential dehydration.
Causes of Vomiting with Diarrhea
GI infection from a virus is the most common cause. A common agent is the Rotavirus. The illness starts with vomiting. Watery loose stools follow within 12-24 hours.
Vomiting alone (without diarrhea) should stop within about 24 hours. If it lasts over 24 hours, you must think about more serious causes. Examples are appendicitis, a kidney infection, diabetes and head injury. A serious cause in young babies is pyloric stenosis.
Kadri shared the most effective ways to help replace lost fluids and rehydrate:
To avoid gastro when a family member is sick, practice meticulous hand hygiene (soap & water for 20+ secs), disinfect contaminated surfaces (use bleach solution), isolate the sick person's belongings, and avoid sharing utensils, towels, or food, as the virus spreads easily through contact with vomit/diarrhea and airborne particles, with infectiousness lasting even after symptoms disappear.
But I don't recommend trying to hold it in if you're in a safe place to vomit. And it's true that if you're vomiting because of nausea, you may feel better afterward. However, inducing vomiting (causing yourself to throw up on purpose) is typically a bad idea.
Nausea is the feeling you get when you think you might vomit (be sick). It can happen for many reasons, but it usually isn't serious. If you are nauseous, you may also vomit, feel dizzy and lose your appetite.
Resting propped up in a seated position with the head elevated at least twelve inches above the feet is ideal. Remain in this seated rested position for a minimum of an hour, or until you are no longer experiencing nausea. Do not lie down all the way. Resting in a fully flat position could trigger vomiting.
The vomiting reflex is mediated by both the autonomic and somatic systems, and consists of two phases:
Symptoms of dehydration
The number of vomiting events ranged from 1 to 7, with 32% of subjects only vomiting once.
Antiemetic medicines
Antiemetics are medicines that help prevent and treat nausea and vomiting. Most antiemetics are prescription medicines. Your doctor might prescribe an antiemetic to treat or prevent vomiting due to: migraines.
