GASTROENTERITIS

Gastroenteritis is an illness triggered by the infection and inflammation of the digestive system. Symptoms can include abdominal cramps, diarrhoea and vomiting. Some of the causes of gastroenteritis include viruses, bacteria, bacterial toxins, parasites, particular chemicals and some drugs.
Gastroenteritis is the commonest cause of pilot incapacitation whilst on duty. A study of over 5000 airline pilots discovered that 29% had at least one episode of incapacitation due to uncontrolled bowel actions. Gastroenteritis is, therefore, a threat to flight safety.
  • "Washing your hands is one of the most effective ways of preventing infection" Correct.
    Hand washing is the single most effective way to prevent the spread of infections. You can spread certain "germs" (a general term for pathogens like viruses and bacteria) casually by touching another person. You can also catch germs when you touch contaminated objects or surfaces and then you touch your face (mouth, eyes, and nose).
  • "3. Liquid intake should be reduced when suffering from gastroenteritis." Incorrect.
    The body is likely to lose a lot of water from diarrhoea. Therefore, when suffering from gastroenteritis, it is important to drink sufficient amount of water.
