An article screenshot from MedPage Today published May 13, 2026. The headline reads, "COVID Antiviral Can Prevent Household Contacts From Catching Virus." Below, a subtitle notes, "Results suggest potential effectiveness in settings such as nursing homes." The article is by Terrence Rudd.
A photo shows a man and a woman standing in a kitchen wearing face masks. The man, in profile wearing a black mask and grey hoodie, hands papers to the woman. She wears a white N95-style mask and pink top while looking down at a small white box.
A "Key Takeaways" section at the bottom features three bullet points:
• No antivirals are approved as postexposure prophylaxis for household contacts of people with COVID-19.
• In this randomized study, 2.9% of household contacts who took ensitrelvir developed COVID within 10 days, as compared with 9% of placebo recipients.
• The FDA is reviewing an application for the oral antiviral, with a decision expected in June.
