A 56-year-old male presented to the emergency department complaining of fever, joint pain, and a generalized rash for three days. He denied headache or ocular complaints. He denied any recent travel. The patient works outdoors at a hotel in the South Beach neighborhood of Miami Beach, Florida, an area known to have active vector-borne transmission of ZIKV at the time of the patient’s presentation []. On physical exam, the patient was afebrile and hemodynamically stable. He had a generalized erythematous maculopapular rash and no other relevant physical findings, including ocular manifestations. Blood urea nitrogen (BUN) and creatinine were elevated (BUN: 23 mg/dL, normal range: 6–22 mg/dL; creatinine: 1.32 mg/dL, normal range: 0.43–1.13 mg/dL). Otherwise, blood chemistry tests were within normal limits. Hematologic tests were all within normal limits. RT-PCR for ZIKV RNA was positive in urine, though the results were not available until after discharge, as the sample was analyzed at an offsite laboratory. Serum was not tested for ZIKV, chikungunya, or dengue viruses. The patient was treated with one dose of ketorolac 30 mg IV. On discharge, the patient was instructed to follow up with his primary care physician.
A 28-year-old female presented to the emergency department complaining of fever, generalized rash, arthralgia, and myalgia. She denied any headache or ocular complaints. She recently traveled to the Dominican Republic where she described having been bitten by mosquitos. History regarding trip duration and timing relative to symptom onset is not available. On physical exam, the patient was afebrile and hemodynamically stable. She had a generalized maculopapular rash and no other relevant physical exam findings, including ocular manifestations. Blood chemistry tests were all within normal limits. Hematologic tests showed very mildly increased monocyte percentage (10.8%, normal range: 0.0–10.0%) with a normal white blood cell count. Laboratory findings were positive for RT-PCR for ZIKV RNA in urine and negative in serum. Chikungunya (IgM and Immunoglobulin G [IgG]) and dengue (IgM) virus serology were negative. Body fluid samples were analyzed at an offsite laboratory; therefore, the results were not available until after discharge. A pregnancy test was negative. The patient was treated with one dose of each of the following medications: morphine 2 mg IV, ondansetron 4 mg IV, and methylprednisolone 80 mg IV. She was also given 1 L of normal saline IV. On discharge, the patient was instructed to follow up with her primary care physician.
