Stomach flu is not airborne, because it is different from influenza or flu. Its common name is gastroenteritis, a viral infection that affects the stomach and the small intestine. The virus that causes stomach flu cannot be spread through air, but a person can get it through direct contact with infected people.
The symptoms of stomach flu include low-grade fever, nausea, vomiting, abdominal pain, diarrhea and headache. These symptoms usually appear two to three days after a person gets the infection, depending on its cause. They can last for a few days, but if the condition is severe they can go up to 10 days, as stated by Mayo Clinic.
The virus that causes stomach flu can be spread from one person to another through sharing items, such as towels and utensils. Direct contact with infected people through kissing and shaking hands also allow the virus to spread. The virus enters the body causing inflammation on the lining of the intestines and the stomach.
As of 2014, there is no specific medication for this condition, as stated by Mayo Clinic. Prevention and self-care are the best way to be safe from the condition. People tend to use antibiotics to treat the condition, which is not recommended since antibiotics can't fight viruses effectively.
