It pays to blow your own horn — or clarinet.
Musical instruments can harbor disease-causing microbes deposited in saliva, suggesting that shared use of instruments in schools risks spreading infections, scientists report in an upcoming International Journal of Environmental Health Research.

They found that clarinets and saxophones carried such microbes for up to three days — longer than flutes or trumpets did.
