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 17-year-old male presented to the emergency department due to his father’s concern that the patient was infected with ZIKV. He had no complaints or symptoms at the time of the visit. The patient reported experiencing joint pain, pruritic generalized rash, headache, and fever on the previous day. He denied any ocular complaints. He had returned from Puerto Rico on the previous day. While in Puerto Rico, he was in contact with a friend who experienced the same symptoms. Per the patient, the friend’s physician told him he had a viral condition. On physical exam, he was afebrile and hemodynamically stable. There were no positive relevant findings on physical exam. Blood chemistry tests were all within normal limits. Hematologic tests showed a mildly decreased white blood cell count (3.1 × 103/mL, normal range: 4.5–13.5 × 103/mL) and a mildly increased hemoglobin (15.3 g/dL, normal range: 11.0–15.0 g/dL) and hematocrit (43.7%, 33.0–43.0%). Lymphocyte percentage was decreased (0.9 × 103/µL, normal range: 1.2–6.4 × 103/µL). RT-PCR for ZIKV RNA was positive in urine and negative in serum. Serology was positive for dengue virus (IgM positive, IgG negative) and negative for chikungunya virus (IgM and IgG negative). Body fluid samples were analyzed at an offsite laboratory; therefore, the results were not available at the time of discharge. The patient received no treatment during this visit. On discharge, the patient was instructed to follow up with his primary care physician and to avoid sexual contact.
