Question

what are the clinical features of viral diarrhoea&giardiasis?

Answer 1

Viral gastroenteritis is a leading cause of severe diarrhea in both adults and children. Many types of viruses can cause gastroenteritis. The most common ones are:
Rotavirus, the leading cause of severe gastroenteritis in children. It can also infect adults exposed to children with the virus. Outbreaks may also occur in nursing homes.
Norwalk virus, which is common among school-age children.
These viruses are often found in contaminated food or drinking water. Symptoms of viral gastroenteritis usually appear within 4 to 48 hours after exposure to the contaminated food or water.
Those with the highest risk for severe gastroenteritis include the young, the elderly, and people who have suppressed immune systems.

Giardiasis is infection with the flagellated protozoan Giardia lamblia. Infection can be asymptomatic or cause symptoms ranging from intermittent flatulence to chronic malabsorption. Diagnosis is by identifying the organism in fresh stool or duodenal contents or by assays of Giardia antigen in stool. Treatment is with metronidazole, tinidazole, or nitazoxanide; alternatives in-clude furazolidone and paromomycin.
