A stomach bug, medically known as viral gastroenteritis, is a common illness that affects the digestive system. In adults, symptoms usually come on suddenly and can be quite uncomfortable. Most stomach bugs last 1 to 3 days, but some people may feel unwell for up to a week, especially if dehydration or fatigue sets in. While symptoms often improve quickly, full recovery of energy and appetite may take a few extra days.

Symptoms of the Stomach Bug
Symptoms of a stomach bug can vary in intensity but commonly include nausea, vomiting, diarrhea, stomach cramps, bloating, headache, body aches, and fatigue. Some adults may experience chills or a mild fever, while others may have no fever at all. Symptoms usually begin 12 to 48 hours after exposure to the virus and peak within the first couple of days.
Viruses That Cause Stomach Bug
Several viruses can cause viral gastroenteritis, but norovirus and rotavirus are among the most common.
Norovirus
Norovirus is the leading cause of stomach bugs in adults. It spreads easily through contaminated food, water, surfaces, or close contact with infected individuals. Symptoms typically appear quickly and last 1 to 3 days, but the virus can still be spread even after symptoms resolve.
Rotavirus
Rotavirus is more common in children but can still affect adults, especially those exposed to young children. Symptoms are similar to norovirus but may last slightly longer, often 3 to 7 days. Adults usually experience milder symptoms compared to children.
How Long Is the Stomach Bug Contagious?
Adults with a stomach bug are contagious from the moment symptoms start and for at least 48 hours after symptoms stop. In some cases, viruses like norovirus can still be shed in stool for up to two weeks, even when you feel better. Good hand hygiene and surface cleaning are essential to prevent spreading the infection.
What to Eat and Drink with a Stomach Bug
Hydration is the top priority. Sip water, oral rehydration solutions, clear broths, or electrolyte drinks to replace lost fluids. Once vomiting settles, bland foods such as bananas, rice, applesauce, toast, crackers, and plain potatoes are easier to tolerate. Avoid dairy, alcohol, caffeine, spicy foods, and fatty meals until digestion returns to normal.
If symptoms are severe, dehydration develops, or vomiting and diarrhea persist for more than a few days, seeking medical care is important to ensure proper treatment and recovery.
