[Norovirus infection in general hospitals for adults]
Aim:
To determine the role of noroviruses in the rise of hospital outbreaks of acute intestinal infections (AII), to study clinical and epidemiological aspects of hospital noroviral infection.
Material And Methods:
Routine diagnostic methods and diagnostic tests on the base of polymerase chain reaction (PCR) were used for identification of group A rotaviruses, noroviruses, astroviruses, adenoviruses, salmonella, thermophilic campilobacteria, shigella, enteroinvasive echerichia (EIEC) in 70 adult patients with AII transferred from general hospital to infection hospital in 2003-2007. A part of the strains was typed with primers specific for genetic cluster G2/4.
Results:
Routine methods failed to identify causes of hospital infection. PCR detected AII etiology in 77.8% patients. Norovirus of the second genotype (G2) was identified as monoinfection in 87.8% verified cases, in association with other agents--in 12.2%. Typed noroviruses belonged to cluster G2/4. Nosocomial norovirus infection was characterized by winter-spring occurrence and a moderate course.
Conclusion:
An essential role of noroviruses in hospital AII outbreaks in elderly patients in winter-spring is shown.
