COVID-19: A One Year Timeline

COVID-19: A One Year Timeline

Siona Manocha, Staff Writer

It seems strange to think that a year has already passed in which the world, as we once knew it, underwent its profound transformation in response to the COVID-19 pandemic. Overnight, our schools were forced to shut down, our restaurants forced to close, and our social interactions forced to halt. From elementary students to college students, we all began schooling online. Masks, temperature checks, and social distancing quickly became the new normal as we continued to fight the battle against this vicious virus. Below is a timeline of the pandemic over the past year — drawing on the profound transformations that have shifted the way of life for so many of our global citizens.
