Dr. John Carroll has sent me an email and allowed me to post it here:
Yesterday I visited an orphanage in Port-au-Prince where we adopted our boy a few years ago.
There are currently 97 children in the orphanage. During the last 7-10 days, 24 of the kids and 5 of the adult staff have come down with a febrile illness. With their fevers they have headaches, joint pain, and chest pain, and general malaise.
I examined a number of these kids yesterday and from a "clinical standpoint" they have signs and symptoms consistent with chikungunya. I could find no focus of infection on any of them, i.e. no pharyngitis, enlarged nodes, pulmonary rales, etc.
We have no lab tests to prove or disprove chikungunya. (And to be honest, if I would have examined this same group of kids a month ago, chikungunya would never have made my list on the differential.)
I'll try to keep an eye on Haiti, and thanks to Dr. Carroll for being there.
