15 month old with blood infection, streptococcus found in blood?

My nephew is 15 months. Two weeks ago he was hospitalized due to croup, treated with antibiotics then sent home after three days. Two days after he was discharged, he developed rotovirus and became severely dehydrated, taken to the ER and given IV fluids, then sent home. He was doing well the rest of that week, had a follow-up with his doc last Thurs, she siad he look great. Then Friday, my sister in law said he was fine all day, took a nap, after he woke up, he was febrile with a 103.5 temp.

He's been in the hospital since Friday, had multiple blood work done. His first set of blood cultures (that was taken when he was admitted) showed there was strep bacteria in his blood. He's been on IV antibiotics from the start, had a kidney and bladder ultrasound done (came out normal). He doesn't have any sores or anything. I'm concerned of how this bacteria got to his blood? Could it have been from the respiratory or diarrhea he had? His doctor doesn't seem to have any answers.

first thing you should do is not listen to most of the answers you'll get.

research web MD and other sights looking for similar cases or ideas. the parents should try other Dr's and most of all don't give up.

If there is a university near try getting ahold of their med dept. be persistent and see if you can get some ideas from them. even a med student can be extremely helpful.

That is a messy situation. The parents need to see a new doctor. Is your nephew at a children's hospital? He probably should be if he isn't. A bacterial infection in the bloodstream can be very serious. This could have occured from his other illnesses not be treated completely. Please make sure he is seeing the best doctors at a childrens hospital! He will be hospitalized getting IV antibiotics for some time!

Strep is a common bacteria, it is found in the nose, ears, and mouth of most people but the immune system keeps them in check. It sounds like the child suffered from the virus which lowered the immune response and the bacteria become opportunistic.

Antibiotics and rest should do the trick.
