Summary

This Canadian study tests whether the antiviral drug tecovirimat (TPOXX) helps non-hospitalized adults with monkeypox recover faster. About 120 participants will receive either the drug or a placebo. The main goal is to see how quickly skin lesions heal and whether running such a trial in Canada is practical.
