COVID-19 treatments focus on managing symptoms and reducing the severity of the disease. Common approaches include antiviral medications like remdesivir, which can help shorten recovery time, and monoclonal antibodies, which target the virus and prevent severe illness. Supportive care, such as oxygen therapy, is also crucial for patients with breathing difficulties. Vaccination remains a key preventive measure against COVID-19. Vaccines, such as those developed by Pfizer-BioNTech and Moderna, help the immune system recognize and fight the virus. In addition, corticosteroids like dexamethasone are used for severe cases to reduce inflammation and improve outcomes.
