COVID-19, coronavirus, antiviral drugs


The emerging Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the causative agent of the Coronavirus Disease 2019 (COVID-19). This disease spreads easily, resulting in large outbreaks in many countries around the world. Currently, no drugs are directly effective treatment or prevention methods. Nevertheless, many studies showed that certain antivirus drugs, other drugs and alternative herbal medicines have ability to inhibit or interfere with SARS-CoV-2 infection. The repurposed antiviral drugs are readily used by patients with COVID-19, as new indications for SARS-CoV-2 infection. This article describes the role of antiviral drugs and herbs, such as finger root and turmeric, the mechanism of the action, and dose and treatment guidelines for COVID-19, according to their symptoms.
