Intestinal viruses can occur when least expected. They can be make people feel terribly ill and are usually very contagious. There are common symptoms to be expected when an intestinal virus strikes, such as vomiting, diarrhea, fever, body aches, dehydration and so on. Causes of an intestinal virus infection include yeast infections, fungus, mold, intestinal parasites and poor hygiene. When these pathogens or germs infect the intestines, they can be life-threatening. Intestinal infection symptoms that become chronic can lead to more severe health and mood problems such as sinusitis, frequent headaches, skin rashes, depression, sleep disorders and teeth-grinding. Prevent intestinal virus infection by practicing good hygiene, drinking clean water and avoiding contact with contaminated foods.

In the present book, twelve typical literatures about intestinal viruses published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on medical science, hemadenology, virology, epidemiology, ect. We hope this book can demonstrate advances in intestinal viruses as well as give references to the researchers, students and other related people.
