Scientists have discovered a ‘nasal spray’ that helps prevent coronavirus infection.

The team from Kraków’s Jagiellonian University and the UK’s University College London found that molecules in the GCPQ compound that is already used in some drugs have a positive electric charge which bind to the virus with electrostatic forces. 

When mice infected with COVID-19 had GCPQ applied to their nostrils, it was found they had smaller amounts of the virus in their respiratory tract and brain.

The researchers also found that the compound had a long residence time in mouse nostrils, with over 13 percent of the injected dose lasting 24 hours.

It was also noted that the mice did not have any side effects, leading the scientists to write: “The polymer may be used as a nasal spray to prevent SARS-COV-2 infections.”
