Ringworm

Is this your child's symptom?

  • One or more ring-shaped spots caused by a fungus
  • Has a rough edge and clearing of the center

Symptoms of Ringworm

  • Round pink patch
  • Clearing of the center as the patch grows
  • Raised, rough, scaly border
  • Usually ½ to 1 inch (12 -25 mm) in size
  • Ring slowly increases in size
  • Often only on one side of the face or body
  • Mildly itchy

Cause

  • An infection of the skin caused by a fungus. It is not caused by a worm.
  • Can often be spread to humans from puppies or kittens that have it. Pet rodents also can carry it.
  • Rarely, can be spread human-to-human. It needs direct skin contact to be passed this way. An exception is that ringworm can occur often among wrestlers. This is because of close body contact during matches.
  • Sometimes, caused by fungus in the soil.

There have been cases of measles in NC, with exposures in Chapel Hill, Durham, and Wake County. We can give the MMR dose early to families who want it. This applies to infants 6-12 months who have not gotten a dose yet or kids under 4-5 years who have not gotten their second MMR dose. At this time, the NC DHHS and health departments are not recommending this unless traveling or living in an area with sustained transmission. Two doses of the MMR vaccine are highly effective (97%) at preventing measles infections. At CHCAC, children receive their first dose at 12 months of age and a second dose at 4 years of age, ensuring they are fully protected as soon as possible, in accordance with the most up-to-date AAP recommendations. Some infants aged 6 months to 11 months who travel internationally or in high-prevalence areas may need a dose to protect them; however, they still require the 1-year and 4-year-old doses as well. If you are ever concerned about a possible exposure to measles, please CALL before entering our office. DO NOT ENTER the office. NC DHHS keeps a list of areas with measles exposures here . This is a highly contagious illness, and special precautions must be taken to prevent spread. The virus can be present in the air for 2 hours after an infected person is in the room, and 90% of susceptible patients can be infected. As always, if you have questions, we are here to help make sense of it all!
