The reason is probably hypotheses about the risk of infection or severity of COVID-19 associated with specific types of drugs (immunosuppressive and anticancer agents, corticosteroids and nonsteroidal anti-inflammatory drugs, angiotensin-converting enzyme (ACE) inhibitors, and angiotensin receptor blockers), which has been highlighted since the beginning of the pandemic, including in the medical literature [16]. Here, ACE is linked to infection.
