Experimental chewing gum reduces Omicron in saliva: study

The gum contains copies of the ACE2 protein found on cell surfaces that the coronavirus uses to infect them, say US researchers

An experimental chewing gum that "traps" SARS-CoV-2 particles in saliva holds promise for curbing transmission of new variants of the virus, according to new data, as US researchers prepare to launch the first human trial.

The gum contains copies of the ACE2 protein found on cell surfaces, which the coronavirus uses to break into cells and infect them.

In test-tube experiments using saliva from individuals infected with the Delta or Omicron variants, the virus particles attached themselves to the
