April 1st 2007
A previously healthy 35-year-old woman was admitted to a New York City hospital after presenting to the emergency department (ED) with a 10- to 14-day history of generalized weakness, progressive frontal headache, and lethargy. She immigrated to Brooklyn, New York, from urban Haiti 9 years previously and had not returned to Haiti since. She denied any recent travel elsewhere and had no pets. An HIV antibody test, performed 4 months before ED presentation, was negative.
