Infectious Diseases - August 2013 Archives

DEAR MAYO CLINIC: I’ve read that there will be new options for getting the flu vaccine this year, including one for people who have egg allergies. How are these new vaccines different, and how do I know which one to pick? How do researchers know they will be safe? ANSWER: You’re right. Beginning this year, several new vaccine options will be offered to help protect you against influenza, or the flu. Rather than just two options, you now will have a range of vaccines from which to choose. At first having so many choices may be confusing. But by doing a little research and having a conversation with your health care provider, you will be able to decide which one is best for your situation. As always, each of the new vaccines has gone through rigorous safety testing before being made available to the public.

The Centers for Disease Control and Prevention (CDC) says 300,000 cases of Lyme disease are diagnosed in the United States each year. That's roughly 10 times more cases than are generally reported to the CDC through routine surveillance. It also makes Lyme disease the most common tick-borne illness in the U.S. The CDC says this new estimate confirms that Lyme disease is a tremendous public health problem in the United States and clearly highlights an urgent need for prevention. Mayo Clinic infectious disease expert Abinash Virk, M.D., says a few basic precautions will reduce the chances of contracting not just Lyme, but all tick-borne diseases. Dr. Virk's top tick-bite prevention tips are:  Use a suitable insect repellent. Check yourself, children and pets after being outdoors. To reduce your risk on hikes, stay on trails. If you leave the path, wear long pants tucked into your socks. If you find ticks, remove them right away. Use force and pinch the tick near its mouth parts, pulling the tick out slowly in a continuous motion. Don’t twist it, which may leave mouth parts embedded in the skin. Keep grass short in yards and avoid ungroomed areas.

DEAR MAYO CLINIC: I was diagnosed last year, at the age of 38, with shingles. What causes someone who is relatively young to get shingles? Does this mean I am more likely to get it again? Should I get the vaccine at this point or wait until the recommended age of 60? ANSWER: Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. Once you have had chickenpox, varicella-zoster stays in your body for the rest of your life. When the virus is reactivated, the result is shingles. [Watch this animation: stages of shingles] Shingles typically involves a band-like rash on one side of the chest, abdomen or face. The rash is usually quite painful. Most people recover from shingles over several weeks. A small number have lingering severe pain, called post-herpetic neuralgia, along the nerve that was irritated when the virus came back.

Dr. Jacobson says there's another change to the immunization schedule to be aware of, as well. Journalists: Sound bites with Dr. Jacobson are available in the downloads. File b-roll of children receiving the flu mist vaccine is also available.
