Coronavirus Disease 2019 (COVID-19)
Conditions
Brief summary
The purpose of this study is to evaluate whether rivaroxaban reduces the risk of a composite endpoint of major venous and arterial thrombotic events, all-cause hospitalization, and all-cause mortality compared with placebo in outpatients with acute, symptomatic Coronavirus Disease 2019 (COVID-19) Infection.
Interventions
Participants will receive rivaroxaban 10 mg tablet orally once daily.
Participants will receive matching placebo tablet orally once daily.
SOC treatment will be determined by the investigator based on local practice and consists of supportive care.

Eligibility
Inclusion criteria
* Coronavirus Disease 2019 (COVID-19) positive diagnosis by locally obtained viral diagnostic test (example, polymerase chain reaction \[PCR\]). This may be nasal swab or saliva test or other available technology to demonstrate current infection * Confirm that participant is known to health system, with at least 1 contact in electronic medical records (EMR) prior to screening * Symptoms attributable to COVID-19 (example, fever, cough, loss of taste or smell, muscle aches, shortness of breath, fatigue) * Initial treatment plan does not include hospitalization * Presence of at least 1 additional risk factor: a) age more than or equal to (\>=) 60 years; b) prior history of VTE; c) history of thrombophilia; d) history of coronary artery disease (CAD); e) history of peripheral artery disease (PAD); f) history of cerebrovascular disease or ischemic stroke; g) history of cancer (other than basal cell carcinoma) h) history of diabetes requiring medication; i) history of heart failure; j) body mass index (BMI) greater than or equal to (\>=) 35 kilogram per meter square (kg/m\^2); k) D-dimer greater than (\>) upper limit of normal for local laboratory (within 2 weeks of the date of the COVID-19 test and prior to randomization)
Exclusion criteria
* Increased risk of bleeding such as a) significant bleeding in the last 3 months; b) active gastroduodenal ulcer in the last 3 months; c) history of bronchiectasis or pulmonary cavitation; d) need for dual antiplatelet therapy or anticoagulation; e) prior intracranial hemorrhage, f) known severe thrombocytopenia g) active cancer and undergoing treatment * Any illness or condition that in the opinion of the investigator would significantly increase the risk of bleeding (example recent trauma, recent surgery, severe uncontrolled hypertension, gastrointestinal cancer, renal failure requiring dialysis, severe liver disease, known bleeding diathesis) * Known allergies, hypersensitivity, or intolerance to rivaroxaban or its excipients * Positive COVID-19 antibody or serology test after 2-week period of acute, symptomatic COVID-19 infection * Known diagnosis of triple positive (positive for lupus anticoagulant, anticardiolipin, and anti-beta 2-glycoprotein I antibodies) antiphospholipid syndrome
