We start in Mason, where Jena King, a nurse practitioner at Allegiance Family Medicine is treating strep throat.
Symptoms include: sore throat, fever, tender enlarged lymph nodes, and headache.
It can also cause nausea, vomiting, or a rash in children.
If you think you have strep, see a doctor.
He or she may prescribe antibiotics.
Tylenol or Motrin can help with fever control and general discomfort.
Gargling warm salt water may be soothing.
In Lansing, Dr. Thomas Stout at Mount Hope Community Medical Center says norovirus is going around.
Symptoms come on suddenly and last one to two days.
They include: nausea, vomiting, diarrhea, stomach cramping, low grade fever -- usually in children, chills and headache.
To treat norovirus, drink plenty of fluids to prevent dehydration and get plenty of rest.
Ease back into eating with bland foods.
Try the BRAT diet: bananas, rice, applesauce, and toast.
Avoid dairy products, caffeine, alcohol and nicotine.
Be wary of taking medications like ibuprofen, as they can make your stomach more upset.
