Is your toddler suddenly limping or refusing to walk? A Kingella kingae infection could be the hidden culprit behind their bone or joint pain. Understanding this common bacterium is the first crucial step toward a swift diagnosis and effective treatment for your child.

What are the main causes of Kingella kingae Infection?

  • Kingella kingae is a bacterium commonly found in the respiratory tracts, specifically the throat and nose, of many healthy young children.
  • The infection typically occurs when these bacteria manage to enter the bloodstream, often following a mild viral upper respiratory tract infection.
  • Minor breaks in the lining of the throat, caused by viruses or even teething, can allow the bacteria to invade and spread elsewhere.
