None of that happened. Instead, a health-care system that already runs close to full capacity, and that was already challenged by a severe flu season, was suddenly faced with a virus that had been left to spread, untracked, through communities around the country. Overstretched hospitals became overwhelmed. Basic protective equipment, such as masks, gowns, and gloves, began to run out. Beds will soon follow, as will the ventilators that provide oxygen to patients whose lungs are besieged by the virus.
