Vincent Ho, Lecturer and clinical academic gastroenterologist at University of Western Sydney, Australia provides a useful overview of what is variously termed “Montezuma’s revenge”, “Delhi belly”, “stomach flu” or “viral gastro”, what causes it, what to do to minimise your risk of suffering from this and the associated risk of developing irritable bowel syndrome - even 8 years afterwards!
"Norovirus is the leading cause of gastroenteritis in adults. Norovirus is highly contagious and outbreaks commonly occur in residential care facilities and hospitals. Patients can remain contagious for at least 48 hours after their symptoms have disappeared." (my emphasis)
"...people with compromised immune systems can have prolonged symptoms."
"We are learning to appreciate the significance of a disordered immune system for long-term gastrointestinal symptoms... Mounting evidence links bacterial, viral, and parasitic infections with an increased risk of developing irritable bowel syndrome."
