Remdesivir is an antiviral medication originally developed to treat infections caused by the Ebola virus. It works by inhibiting the replication of viruses, which helps to reduce the severity and duration of viral infections. In 2020, remdesivir gained attention for its potential use in treating COVID-19, a disease caused by the SARS-CoV-2 virus. Clinical studies showed that it could shorten recovery time for some patients, leading to its emergency use authorization in various countries.
