The epidemiology and burden of rotavirus in China: a review of the literature from 1983 to 2005.
We reviewed studies of rotavirus in MEDLINE and the Chinese literature to get a preliminary estimate of the burden of rotavirus gastroenteritis in China and the epidemiology of the disease. Studies were selected if they were conducted for a period 1 year or more, had more than 100 patients enrolled, and used an accepted diagnostic test. Overall, in 27 reports of children hospitalized for diarrhea in urban areas and 3 in rural areas, 44 and 33%, respectively, had rotavirus identified as the etiologic agent. Rotavirus was less commonly detected in children with milder illness seen in clinics (26% in urban and 28% in rural areas) and those cared for in the community (9%). The four main strains of rotavirus in circulation worldwide were also found in China and while G1 was the predominant strain overall, G3 emerged to be the most common strain in 9 of the 12 most recent studies. The disease has a distinct winter seasonal pattern and affects most children in their first 2 years of life. Although further studies are required to fully assess the burden of rotavirus diarrhea before decisions can be made about vaccine use, this review suggests that development and implementation of rotavirus vaccines should be a national priority.
