RAPID CITY, SD (KEVN) The back to school germs seems to be hitting relatively early this year. And you may be wondering when should I bring my child in to see the doctor, well a couple of the most common bacterial and treatable infections are going to be strep and walking phenomena. Strep throat almost always causes a fever and a sore throat, especially when swallowing and it does not cause a cough or runny nose or congestion. If you think your kid might have strep bring them in to see the doctor. Mycoplasma is the scientific name for walking phenomena and can cause dry and hacky coughs, sometimes some other vague symptoms like a headache, or stomach ache and can last for quite a while. If your child has been exposed to walking phenomena or has just been suffering from a cough for two to three weeks it might be a good idea to get them checked out. Whooping cough is always something to think about when kids get back together but is actually quite rare. It is vaccine preventable. So hopefully your child is up to date as well as all their peers and the chances of that spreading are pretty low. otherwise, most of your infections from school are going to be cold viruses or stomach bugs so lots of runny nose, congestion, cough, maybe some vomiting and diarrhea with the stomach bug. If you have any concerns you can always call your child's pediatrician. This is Dr. Cara Hamilton at Black Hills Pediatrics with your Health Watch.
