About this study

The goal of this randomized controlled double-blind clinical trial is to test the drug tecovirimat in patients with mpox (previously known as monkeypox) disease. The main questions it aims to answer are: * Is tecovirimat effective in treating mpox infection. * Is tecovirimat safe to treat patients with mpox infection. Participants will receive either the drug tecovirimat orally, 600 mg twice per day, or a matching placebo. The outcome of the infection and the side effect experienced will be compared between the two groups.
