The virus' effects could be felt in all aspects of life, business, politics, sports, entertainment - locally and around the globe.
Mask mandates and colored phases of closings were yet to be the norm, but the novel coronavirus was on tops of people's minds and newscasts.
On March 11, 2020, there were more than 118,000 cases of COVID-19 in 114 countries and 4,291 people lost their lives.
A year later, there have been more than 118,000,000 cases worldwide and over 2.6-million deaths, according to John Hopkins University.
During an afternoon press briefing on March 11, 2020, the World Health Organization officially classified COVID-19 as a pandemic.
"In the days and weeks ahead, we expect to see the number of cases, the number of deaths, and the number of affected countries even higher," WHO Director-General Dr. Tedros Adhanom Ghebreyesus said. "WHO has been accessing this outbreak around the clock and we're deeply concerned, both by the alarming levels of spread and severity, and by the alarming levels of inaction."
"We have therefore made the assessment that COVID-19 can be characterized as a pandemic."

President Donald Trump addressed the nation that Wednesday night. He announced he was cutting off travel from Europe to the U.S. for 30 days. The restrictions did not apply to the United Kingdom.
"For all Americans, it is essential that everyone takes extra precautions and practice good hygiene," Trump said. "Each of us has a role to play in defeating this virus."
Shortly thereafter, actor Tom Hanks announced on social media that he and his wife actress Rita Wilson had contracted the coronavirus.
Hanks said the two were in Australia and felt a bit tired, had colds, and some body aches. He said Wilson also suffered chills and slight fevers.
"To play things right, as is needed in the world right now, we were tested for the coronavirus, and were found to be positive," Hanks said.
The couple would recover from the virus and Hanks would go on to host "Saturday Night Live" remotely from his home in April.

The sports world's months-long pause would start to take shape on this date. Our sister station ESPN produced a '30 for 30' podcast 'March 11 2020,' in which they describe that Wednesday as the "day everything changed."
Around that time of Tom Hank's social media post, the NBA announced it was suspending its season after a player on the Utah Jazz, later identified as Rudy Gobert, tested positive for COVID-19.

A day later, the NCAA would cancel the tournaments.
COVID-19 was the big story in the Delaware Valley on March 11, 2020, as cases were starting to be confirmed throughout the region.

A year later, Philadelphia has reached more than 120,000 cases.
Today, local officials are gradually lifting restrictions put in place to curb the spread of COVID-19. The day before March 11, 2020 was the last time fans attended a Philadelphia Flyers game - until they were allowed back this week.
