Human noroviruses cause acute gastroenteritis, a global health problem for which there are no vaccines or antiviral drugs. Although most healthy patients recover completely from the infection, norovirus can be life-threatening in infants, the elderly and people with underlying diseases. Estimates indicate that human noroviruses cause approximately 684 million illnesses and 212,000 deaths annually.
