Common Infections May Contribute to Strokes

THURSDAY, Oct. 8 (HealthDay News) -- Adults with the skin disease shingles appear to be at raised risk for stroke, especially when it affects the area around the eyes, researchers report.

Previous reports have linked shingles with stroke risk, but "the exact frequency and risk for these phenomena are still unknown," said study lead author Dr. Jiunn-Horng Kang, a principal investigator in the Neuroscience Research Center of Taipei Medical University Hospital, Taiwan. His team published their findings in the November issue of Stroke.

"Our study is the first to explore these issues with a nationwide population-based data," Kang said.

Shingles is a painful skin rash resulting from infection by the varicella zoster virus, which causes chickenpox. The virus remains in the body after recovery from chickenpox and can erupt again to cause shingles.

Kang and his colleagues studied data on 7,760 adult Taiwanese who were treated for shingles between 1997 and 2001. In the year after treatment, 133 of them, or1.7 percent, had strokes. The incidence in a control group of 23,280 adults who were not treated for shingles was 1.3 percent (306 people).
