Yes, you can get the stomach flu (viral gastroenteritis) from sleeping in the same bed as someone sick, as the viruses are highly contagious and spread through contact with vomit/feces, contaminated surfaces, or airborne particles from vomiting, making close contact and shared bedding high-risk areas, though good hygiene (like handwashing) reduces risk. It's best to sleep separately if possible and avoid sharing bedding, towels, and dishes to prevent transmission.
And the virus can linger on objects and surfaces for days or even weeks, spreading easily in crowded environments such as nursing homes, day care centers and cruise ships. “This virus is very easily transmitted from one person to the next,” she said, noting that norovirus “is the most common cause of … gastroenteritis.
Norovirus symptoms tend to pass after a few days, but the virus can live on surfaces — and sicken others — for up to two weeks. Here's how to fight it.
Provided you've got clean hands, she says you should be OK to share a bed or sleep in the same room as a partner or child. Be aware, though, that the infection may also be spread in the air when people vomit.
According to researchers, symptoms of norovirus, rotavirus, and sapovirus usually show up 1 to 2 days after exposure, while it can take 4 to 5 days for people to develop symptoms of astrovirus. Symptoms of adenovirus mostly show up 5 to 6 days after exposure, but they can take anywhere from 2 to 14 days to appear.
A person with norovirus touches surfaces with their bare hands. Food, water, or objects that are contaminated with norovirus are placed on surfaces. Tiny drops of vomit from a person with norovirus spray through the air, landing on surfaces or entering another person's mouth.
Nausea, vomiting or both. Stomach cramps and pain. Occasional muscle aches or headache. Low-grade fever.
The best way to prevent catching a stomach bug: thorough hand washing. Everyone in your family should wash their hands with soap and water before eating and after using the bathroom. If you have an infant, be sure to follow proper handling and disposal of dirty diapers.
Influenza viruses tend to survive longer on hard, nonporous surfaces than porous surfaces. Research shows both influenza A and B viruses survive for 24 to 48 hours on hard surfaces like stainless steel, doorknobs and plastic, but survive for less than 12 hours on cloth, paper and tissues.
Prevention
If one member of your family gets sick with norovirus, others are likely to get it too unless you isolate the sick person, wash your hands obsessively with soap and water and clean your home thoroughly.
To disinfect, use a chlorine bleach solution with a concentration of 1,000 to 5,000 ppm (5 to 25 tablespoons of household bleach [5% to 8%] per gallon of water) or use an EPA-registered disinfecting product against norovirus.
Signs and symptoms of norovirus infection may start suddenly and include:
You might find that you can eat bland, easy-to-digest foods at first, such as soda crackers, soup, oats, noodles, bananas and rice. Stop eating if your nausea returns. Avoid certain foods and substances until you feel better. These include caffeine, alcohol, nicotine, and fatty or highly seasoned foods.
People who have norovirus are still contagious for 48 to 72 hours after recovering. You should limit certain activities, but you may be able to resume others. To reduce your risk of spreading the stomach bug to others: Avoid preparing and serving food.
It's thought that the flu virus spreads in the saliva droplets that result from coughing and sneezing. These droplets can travel as far as six feet, where they land in the nose or mouth, or are inhaled into the lungs of healthy individuals.
How to disinfect your home after an illness
The influenza (flu) virus can live for up to 24 to 48 hours on hard surfaces. The coronavirus can live from a few hours to a few days. Bacteria such as E. coli and salmonella may only live for 20 minutes but can live for up to four hours on hard surfaces.
How to Keep Your Sheets Fresh Without Putting Them in the Wash
You're most contagious during the acute phase of the infection (when you have symptoms) and for a few days after.
What to drink when you have the stomach flu
Gastroenteritis. Gastroenteritis is often mistaken for stomach flu although it is actually an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. Symptoms of gastroenteritis include diarrhea, abdominal pain, vomiting, headache, fever and chills.
The most common symptoms of illness include nausea, stomach cramps and severe and repeated vomiting and diarrhea. It is possible, but less common, for norovirus to cause a low-grade fever, chills, headache and body aches. Symptoms can begin from 12 hours to two days after initial contact with the virus.
Research consistently shows that approximately 5-10% of adults with COVID-19 report GI symptoms such as nausea, vomiting, or diarrhea. Typically, patients with GI symptoms of COVID-19 will also have the more common upper respiratory symptoms that accompany COVID-19, such as a dry cough or difficulty breathing.
Yes, it is possible to have a stomach virus without vomiting or diarrhea. People can sometimes have symptoms that may be less obvious, such as abdominal discomfort, nausea, or upset digestion. People can also have a stomach virus with no symptoms at all.
