Are the new covid variants delta or omicron causing blood clots like the original strain? also, as someone with factor v leiden (one copy) would you recommend blood thinners if i catch covid? (i'm already vaccinated 2 pfizers) thanks?

The new Covid-19 variants also cause blood clots (the only difference between the variants is the spike proteins by which this virus enters the human cell). By UPTODATE: "if thromboprophylaxis is used in an outpatient setting, UpToDate suggests a regimen such as rivaroxaban 10 mg daily for 31 to 39 days." This recommendation is for patient with a high risk of thrombosis.
