There is an urgent need to understand the underlying mechanisms contributing to thrombotic and inflammatory complications during COVID‐19. Data from independent groups have identified that platelets are hyperreactive during COVID‐19. Platelet hyperreactivity is accompanied by changes in platelet gene expression, and enhanced interactions between platelets and leukocytes. In some patients, SARS‐CoV‐2 mRNA has been detected in platelets. Together, this suggests that SARS‐CoV‐2 may interact with platelets. However, controversy remains on which receptors mediate SARS‐CoV‐2 platelet interactions. Most, but not all, transcriptomic and proteomic analyses fail to observe the putative SARS‐CoV‐2 receptor, angiotensin converting enzyme‐2, or the cellular serine protease necessary for viral entry, TMPRSS2, on platelets and megakaryocytes. Interestingly, platelets express other known SARS‐CoV‐2 receptors, which induce similar patterns of activation to those observed when platelets are incubated with SARS‐CoV‐2. This article explores these findings and discusses ongoing areas of controversy and uncertainty with regard to SARS‐CoV‐2 platelet interactions.
