The problem is that is PPE now scarce and being bid up to much higher than pre-crisis prices and actively bankrupting hospital systems. Right now, PPE in the USA is unfortunately a zero sum game. If healthcare providers are unable to keep themselves from getting sick, then there will be fewer over them to take care of you/your family when you need it. This is the tragedy of the commons at work.
Take reasonable personal precautions. If you have masks, wear them. Use disposable PPE judiciously. Don't buy $2k worth of N95s, please.
