Oral drug candidate blocks transmission of measles-like disease in ferrets

Oral antiviral blocks airborne measles-like virus spread in ferret model

A new oral antiviral drug candidate, administered either before or after direct-contact or airborne exposure to canine distemper virus, which causes measles-like disease in ferrets, blocks virus transmission and reduces clinical symptoms, according to a study published in the journal Nature Microbiology by researchers at the Center for Translational Antiviral Research (CTAR) at Georgia State University.

A new antiviral could stop measles before an outbreak takes off

An experimental pill prevented a measles-like virus from spreading through the air or through close contact in ferrets. It worked when given shortly before or after exposure and also shortened illness and the period when infected animals remained contagious. Researchers say the drug could one day complement vaccination and make outbreaks easier to contain.

Oral Antiviral Blocks Measles-Like Virus Transmission in Ferrets

This year, the United States has recorded the highest number of measles cases since 2000, the year that the disease was declared eliminated from the country. As of mid-July, 2,260 measles cases were reported—just 29 cases less than the entire year of 2025. And outbreaks are widespread, with 34 new outbreaks reported in 2026. The reason for this surge in cases is waning vaccination rates across the country. Given that, the production of new antiv…
