From the Overview: "The World Health Organization (WHO) first declared COVID-19 [coronavirus disease 2019] a world health emergency in January 2020; on March 11 it announced the viral outbreak was officially a pandemic, the highest level of health emergency. Since then, the emergency evolved into a global public health and economic crisis that affected the $90 trillion global economy beyond anything experienced in nearly a century. [...] By early March 2020, the focal point of infections shifted from China to Europe, especially Italy, but by April, the focus had shifted to the United States, where the number of infections had been accelerating. By April 2021, India and Brazil emerged as viral hot spots with the number of infections and deaths reaching daily record levels in those countries. [...] The infection has sickened over 174 million people globally with over 3.7 million fatalities. The United States reported that by mid-June 2021, over 33 million Americans had been diagnosed and nearly 600,000 had died from the virus. [...] During the G-7 (Group of Seven) summit in England on June 11, 2021, the United States and the other G-7 leaders announced they would provide a combined total of 1 billion doses of the COVID-19 vaccine in addition to lifesaving medical supplies, oxygen, diagnostics, therapeutics, and personal protective equipment (PPE) to low and middle income developing countries."
