Viral antibodies are known to develop upon initial infection; however, it is unclear the amount of protection this confers against reinfection. Additionally, COVID-19-associated coagulopathy (CAC) is a well-documented phenomenon; however, there are no high-quality studies to support the treatment of outpatients beyond standard indications of venous thromboembolism (VTE) prophylaxis. This case describes a patient with either COVID-19 reinfection or prolonged course of CAC resulting in pulmonary embolism (PE).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 40-year-old healthy man presented with fever and cough. He tested positive for COVID-19 and was sent home to self-quarantine. His symptoms resolved and repeat COVID-19 testing returned negative. Two months later, he developed dyspnoea on exertion and syncope. Computed tomography with PE protocol demonstrated acute bilateral PE, and repeat COVID-19 testing returned positive. He was escalated to catheter-directed thrombolysis, but prior to the procedure went into cardiopulmonary arrest. Cardiopulmonary resuscitation was initiated and full-dose systemic alteplase was administered. Cardiothoracic surgery was consulted for consideration of veno-arterial extracorporeal membrane oxygenation; however, return of spontaneous circulation was unable to be achieved.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>This case raises the question of COVID-19 reinfection and prolonged risk of VTE due to CAC. We believe the patient was reinfected with COVID-19 provoking his PE; however, a single COVID-19 infection causing a prolonged course of CAC is possible. Until better data exists, decisions regarding outpatient prophylaxis must be individualized to weigh the risks of bleeding against the risk of thrombosis.<\/jats:p>\n
