A man in his 20s who returned to the U.S. from Wuhan, China, the epicenter of the coronavirus outbreak, has contracted the virus, the Centers for Disease Control and Prevention alerted health officials in Boston on Saturday. His is the eighth known case in the U.S.

Details: Rita Nieves, executive director of the Boston Public Health Commission, said officials "are not asking Boston residents to do anything differently" and that "risk to the general public remains low." The man was isolated soon after returning to Massachusetts, and his "few close contacts" are being monitored for symptoms.

“We are grateful that this young man is recovering and sought medical attention immediately. Massachusetts has been preparing for a possible case of this new coronavirus, and we were fortunate that astute clinicians took appropriate action quickly. Again, the risk to the public from the 2019 novel coronavirus remains low in Massachusetts.”
— Massachusetts Public Health Commissioner Monica Bharel

Driving the news: U.S. officials declared a public emergency on Friday and said America will deny entry into the country beginning Sunday to any foreign national who poses a risk of infection.

Big Tech companies are scrambling to figure out what China's imposition of a new national security law in Hong Kong means for their businesses there.

The big picture: Tech companies, like other multinationals, had long seen bases in Hong Kong as a way to operate close to China without being subject to many of that country's most stringent laws. Now they likely must choose between accepting onerous data-sharing and censorship requirements, or leaving Hong Kong.

Two new court actions — one by the Supreme Court and another by a federal judge — together highlight and raise the energy stakes of November's election.

Why it matters: The legal actions mean the results of the 2020 election could very well decide the fate of Keystone XL and Dakota Access, two projects at the heart of battles over fossil fuel infrastructure.
