The painful, burning twinge and irritate skin that can be an early warning sign of shingles is often overlooked or misdiagnosed at the time when antiviral medications can be effected at shortening the outbreak.
Karen Roos, M.D., the John and Nancy Nelson Professor of Neurology at the Indiana University School of Medicine, said she sees about 10 new cases of shingles each month. One person in 100 over the age of 60 typically will develop shingles.
Although a vaccine is available to prevent shingles, Dr. Roos said the shingles vaccine is too new to have a proven safety record. She believes there are other effective ways to monitor people at risk for a shingles outbreak.
The herpes zoster virus that causes shingles also causes chickenpox, a disease more common in children. The virus lies dormant in the nervous system and can reactivate as shingles when a person's immune system becomes impaired by age, illness, stress, disease or other factors.
Although shingles can be extremely uncomfortable during the outbreak, long-term neurological pain can persist and be debilitating for months.
"People who are at risk should have their virus antibody levels checked with a simple blood test regularly to see if an antiviral drug should be prescribed to prevent the onset of shingles," said Dr. Roos. "People need to be aware of the symptoms, which can include pain or tingling in the back, usually to the right or the left of the midline, and reddened skin in the same area. If caught in time and antiviral medications are prescribed, the shingles outbreak can be disrupted."
