People who would never thing of borrowing a used toothbrush will check out someone else's harmonica. Needless to say, this is not an ideal time to be playing other people's wind or reed instruments without sterilizing them first.

The Wuhan coronavirus (aka CCPneumonia) can apparently survive for days on hard surfaces. Though you may be tempted to use an ultrasonic cleaner, although they do a very good job at mechanically cleaning the harmonica, ultrasonic cleaners aren't very effective when it comes to killing microbes (though I'm sure that many are washed off in the process). While I doubt any of the consumer ozone sanitizers have been scientifically tested, ozone will indeed kill viruses and you can get a battery powered ozone sanitizer for $50 or less that will fit 10 or 12 diatonics at one time.

This is the one I use and it's just $30 on eBay. Less than the cost of a pro harp. https://www.ebay.com/itm/Ion-Ozone-Sanitizer-Toys-Dentures-Phones-Sponges-COPD-masks-oxygen-masks-/371680586822

You can also use an ozone sanitizer to sterilize your paper money and credit/debit cards, likely the most contaminated things you carry.

PS. If you have a 3D printer, you can print N95 masks:

https://3duniverse.org/2020/03/18/3d-printing-to-help-with-the-coronavirus-pandemic/ - this one requires some assembly

https://www.billingsclinic.com/foundation/ - sized for an adult but they also have the CAD files if you need to resize.
