"New research released Thursday suggests that one cell phone-related health threat that many people face may not be from their own phones at all -- but from their doctors' mobile devices.
In a study published in the journal Annals of Clinical Microbiology, researchers at Ondokuz Mayis University in Samsun, Turkey screened the mobile phones of 200 health care workers in hospitals for germs that are known to be dangerous to human health.
What the researchers found was that 94.5 percent of the phones tested -- nearly 19 out of 20 -- were contaminated with some kind of bacteria. Worse, some of the bacteria that the researchers found were known ""superbugs"" -- bacteria that are resistant to one or more commonly used antibiotics.
Allergic to Your Cell Phone?
Those with allergies to certain metals, such as nickel, may experience yet another side effect of exposure to their cell phones in the form of contact dermatitis.
In recent years, dermatologists have begun to see an increasing number of contact dermatitis patients who are allergic to these metal components in their cell phones.
""Some people are extremely nickel-sensitive,"" Dr. Lionel Bercovitch, a professor of dermatology at Brown Medical School, told Kirk Fernandes of ABC News OnCall.
Nickel is a metal that's used in a wide variety of products, including jewelry, belt buckles and watch bands. It's the most common cause of contact dermatitis in the developed world.
The symptoms of a nickel reaction range from mere redness to an obvious rash, or even blisters.
