We start in Okemos, where Dr. Dennis Perry from Meridian Primary Care is treating some cases of enterovirus.

Symptoms include an extremely severe sore throat. Children will also get a very high fever, along with painful blisters in the mouth, which results in a decrease in appetite.

You should drink plenty of fluids to fight enterovirus. Taking over-the-counter pain relievers and fever-reducers will help, too, but antibiotics, won't.

In Lansing, Dr. Hugh Brainard from Ingham Internal Medicine and Pediatric Associates says hay fever is going around.

Symptoms include eye irritation, sneezing, throat irritation, and runny, stuffy and itchy nose.

There's no cure for allergies, but staying inside during peak pollen times can help. Over-the-counter antihistamines can help control symptoms, but if they don't, see a doctor to discuss other treatment options.

And physicians assistant Michelle Spica, from the Charlotte Medical Group, says swimmer's ear is also going around.

Symptoms include pain and swelling in the ear canal, with more pain when you pull back or touch the outer ear. There may also be some discharge from the ear, and itching.

Ear drops with antibiotics can help with the infection. Corticosteroids can help with itching and inflammation.

Avoid using Q-tips or putting objects in the ear; that can cause pain and increased infection.

To prevent swimmer's ear, avoid swimming in polluted waters, and be sure to dry the ear completely after swimming.
