Introduction: Zika virus (ZIKV) is transmitted by the bite of the Aedes species mosquito. Infected patients may present flu-like symptoms or even neurological deficits. In Puerto Rico (PR), an increased number of cases of ZIKV were noted in 2016 and a surveillance system was established for monitoring. As of August 2018, a total of 36,097 symptomatic cases of ZIKV had been reported in PR by the Centers for Disease Control and Prevention of the United States. One of the neurological complications secondary to ZIKV was Guillain–Barré syndrome (GBS). The surveillance system reported that 66% of patients with GBS who were tested were positive for ZIKV. This study aims to identify the functional outcomes of GBS patients related to ZIKV as compared to patients with GBS nonrelated to ZIKV during inpatient rehabilitation using functional independence measure (FIM) score. Materials and Methods: A retrospective case–control study design was used. Patients with a diagnosis of GBS admitted to an inpatient rehabilitation unit between January 1, 2016, and August 15, 2017, were deemed eligible. Patients were divided in two groups: (1) GBS-positive ZIKV (experimental) group and (2) GBS-negative ZIKV (control) group. A total of 21 patients were identified; 16 qualified for the study. The primary outcome was the admission and discharge FIM score. Results: A total of 11 (69%) patients were ZIKV positive or presumptive positive and 5 (31%) were ZIKV negative. One hundred (100%) of the patients had significantly improved FIM scores upon discharge. No significant differences between the ZIKV groups were noted on admission or discharge FIM scores. Conclusion: This study demonstrated that all GBS patients benefit from inpatient rehabilitation facility admission and therapy regardless of ZIKV status. Rehabilitation outcome is not determined by ZIKV status.
