If the intended goal of wearing a mask is to protect others (since you have no way of knowing that you're not infected), then there's no practical reason that a mask can't be reused, whether sanitized or not.
I've sent pleas to several local and national government agencies and health directors, but it's unlikely that such e-mails will be read, so information needs to be disseminated another way. The fact that the western world hasn't called for widespread use of even cloth masks is unconscionable. Presume you're already infected to protect others.
