By now, we are all familiar with COVID-19, the highly infectious illness that has disrupted many lives and taken many others. But do you know what signs indicate someone with this illness needs emergency medical care? Many cases may be mild, but there is still the risk of serious illness or even death. Emergency symptoms include difficulty breathing, chest pain or pressure, confusion, can’t stay awake, or pale, gray, or blue skin, lips, or nail beds. The best treatment is, of course, prevention via masking, vaccinations, social distancing, isolating if ill, and avoiding those who are ill.
