Japan sends Avigan to United Kingdom for hantavirus cases

Published on May 19, 2026 | Translated from Spanish

The Japanese government has activated an international cooperation protocol to supply the United Kingdom with the antiviral drug Avigan, also known as favipiravir. This decision responds to the recent emergence of hantavirus cases in British territory. The drug, originally developed against influenza, is emerging as a response tool for health emergencies.

Favipiravir: a broad-spectrum antiviral in the spotlight 🧬

Avigan is an inhibitor of viral RNA polymerase, designed to block the replication of the pathogen's genetic material. Its mechanism of action is not specific to a particular virus, allowing its use against influenza, Ebola, and now hantavirus. The dose and duration of treatment are adjusted according to the strain. Japan maintains strategic reserves of the drug and has exported it to several countries under bilateral agreements.

Hantavirus makes an appointment and Japan sends reinforcements 😷

It seems hantavirus has jumped on the trend of traveling abroad without warning. And while some countries send tourists, Japan sends medicine. The curious thing is that Avigan, which already had its moment of fame against the flu, now becomes the pharmaceutical wildcard for any self-respecting bug. All that's left is for it to be requested for a hangover.
