Coronavirus Watch: Virus has been spreading in US for one year

Wednesday marks one year since the first case of COVID-19 was reported in the U.S. — a 35-year-old man returning to Washington after a 3-month trip to visit family in Wuhan.

In that time, millions of cases have been reported, and the U.S. death toll will soon eclipse the number of American casualties from World War II. But the war with the virus continues as tens of thousands test positive every day and the nation's daily death counts routinely tops 3,000.

It's Tuesday, and this is Coronavirus Watch from the Paste BN Network. Here are today's headlines, as of 2 p.m. EST.

• Several California counties are pausing administration of more than 300,000 Moderna coronavirus vaccine doses after state health officials received reports of “possible allergic reactions” from one clinic.
• Can companies require their employees to receive COVID-19 vaccines? Yes, but they would have to comply with current workplace laws. Here's how they could issue such a mandate.
• What will travel look like in 2021? Here are 15 travel trends to watch, from digital vaccination passports to a potentially busy summer season.
• Vaccine check: CDC data, which has not been updated since Friday morning, shows more than 31 million vaccine doses distributed and 12.3 million shots administered.
