Members of a relatively new virus family, the astroviridae, astroviruses are now recognised as a cause of gastroenteritis in children and adults. The main symptoms are diarrhoea, followed by nausea, vomiting, fever, malaise and abdominal pain. Some research studies have shown that the duration of the symptoms are approximately three to four days. Astrovirus infection is not usually a severe situation and only in some rare cases leads to dehydration. Infected people do not need hospitalization because symptoms reduce by themselves, after a small period of time.
Диагностика
Electron microscopy, enzyme-immunoassay, immunofluorescence, and polymerase chain reaction have all been used for detecting virus particle, antigens or viral nucleic acid in the stools of infected people. A method using real-time RT-PCR, which can detect all human astrovirus genotypes, has been reported.
