The rapid spread of the COVID-19 delta variant has led to a spike in cases averaging more than 150,000 a day, a dramatic jump from the 13,000 cases per day the U.S. was experiencing just a couple of months ago. The rise has led some government officials to backpedal reopening policies and renew their focus on prevention. The Centers for Disease Control and Prevention recently modified guidance on mask-wearing for vaccinated individuals, leading several municipalities, universities, and retail brands to reinstate mask mandates. New York City and San Francisco are even requiring proof of vaccination for many indoor activities such as dining, movie theaters, and gyms.
