World marks 1 year since pandemic declared

A year ago today when the World Health Organization (WHO) declared COVID-19 spread a pandemic, there were more than 118,000 cases. Today, the global total topped 118 million, with levels rising again in some countries, but retreating in others. And across the globe, countries are rushing to vaccinate their people in attempts to get ahead of the spread of new more transmissible SARS-CoV-2 variants and others that could evade immunity from natural infection or the vaccine.
