3 year old staph infection on knee?

[Acidrain]

My son fell and grazed his knee last week and the graze has gone all yellow and yellow spots have started forming around the graze. The doctors have said a staph infection and gave antibiotics.

What cause this sort of infection?

Staph is a sort of bacteria that naturally lives on everyone's skin. A graze breaks the skin, so the bacteria that weren't causing any problem on intact skin can then get into the tissues in/under the skin, and as they multiply turn into an infection.

I think Staph infections are quite common on the skin and are treated well with antibiotics. Please keep an eye on your child though in case they become unwell. My son got a Staph infection in his blood last year (no idea how it got there), and he ended up quite unwell and spent 3 weeks in hospital. A temp above 40 for 5 days was the initial problem for us.

Hi I know it's been a couple of years since your post but did your son have sepsis? My 7 year old son is recovering from getting a severe staph aureus skin infection which got into his blood and resulted in sepsis. I'm so worried what will happen when he gets off the antibiotics as his face is showing a new rash bit like a heat rash. Please any advice welcome

I don’t think they ever described it as sepsis to me but it was found to be pvl negative strand of Staph aurus which apparently is particularly concerning (it did warn us a private room!). In terms of his health he made a full recovery - determined by normalised temperatures and Blood esr and crp back to normal. (Plus feeling ok) However, his blood infection rooted in his tibia and his main problem was that he developed osteomyelitis. Whilst this was treated effectively with 3 weeks iv and then 6 weeks oral antibiotics the osteomyelitis caused damage to his growth plate, so sadly this is the main permanent problem since the infection. I do remember them doing an ultrasound scan thing of his heart to check if any problems had been caused there but nothing significant was noted. I hope your little one makes a full recovery - sorry I can’t give you any guidance about sepsis. I would advise, keep a record and timeline of everything (bloods, temps, changes in meds etc.) as it’s very easy to forget it all. Good luck
