Which doctor treats this

  • Start with your primary care provider (family doctor or internist).
  • They may send you to an infectious disease specialist.

Children, pregnancy, and older adults

  • Healthcare workers: Report exposures right away.

Pregnancy and breastfeeding

  • If you're pregnant or planning to be, tell your prenatal provider about this condition.
  • Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
