A 2 year old is brought in because all of his fingernails and toenails are falling off, painlessly. On review of the ED electronic medical record, he was seen 6 weeks ago and diagnosed with a viral infection. What viral infection did he have?

What viral infection results in later onychomadesis?

    C) Onychomadesis, a fancy term for nails falling off, is a complication seen after hand-foot-mouth disease, particularly if caused by the A6 strain of Coxsackie virus. This complication is usually seen 4-8 weeks after the primary infection, and the nails typically grow back over the next several months. Either only some of the nails or all of the nails may be affected.
