Australia’s Victoria Set to Tighten Restrictions: Reports (7:07 a.m. HK)

Victoria, Australia’s second-most populous state, is set to tighten lockdown measures amid rising virus cases, local media reported, with an announcement expected as soon as Sunday morning.

Premier Dan Andrews could announce that Victoria’s capital, Melbourne, would move to a New Zealand-style lockdown which would close most businesses, keeping only essential services operating and shutting down most of the city’s public transport network, Sky News reported.

The Age newspaper said the tighter restrictions could be in place for six weeks and begin as soon as Wednesday.

London Lockdown Weighed: Reports (6:40 a.m. HK)

Prime Minister Boris Johnson is considering sealing off Greater London and ordering at-risk members of the population to stay at home under a potential scenario designed to avert a second national lockdown, according to news reports.

Possible measures include locking down the capital if infection rates spike and tightening quarantine rules on those flying into the U.K., The Sunday Telegraph reported. There would be travel curbs in and out of the M25 highway encircling Greater London and a ban on overnight stays, according to the Sunday Times.

Elderly people and those considered to have an increased risk from Covid-19 could be asked to stay at home, and “harder” local lockdowns could be ordered than the restrictions already imposed on parts of northern England.

Governor Ron DeSantis has declared a state of emergency and Covid testing sites will be shut until Wednesday. Virus statistics are likely to vary in Florida over the next few days.

Democrat Tests Positive, Blasts Republicans (2:30 p.m. NY)

Democratic Representative Raul Grijalva said he’s infected with the coronavirus, days after a Capitol Hill hearing where a Republican House member in attendance later tested positive for Covid-19.

“While I cannot blame anyone directly for this, this week has shown that there are some Members of Congress who fail to take this crisis seriously,” said the Arizona Democrat. “Numerous Republican members routinely strut around the Capitol without a mask to selfishly make a political statement at the expense of their colleagues, staff, and their families.”

Grijalva said in a statement he isn’t exhibiting symptoms and has been self-isolating at his home in Washington since Wednesday upon learning that Texas Republican Representative Louie Gohmert tested positive.

New York to Decide on Schools Next Week (12:28 p.m. NY)

New York Governor Andrew Cuomo said he would make a decision on school reopening in the coming week, based mostly on the overall infection rate. He said New York City missed a Friday deadline to submit reopening plans.

“An initial decision at this point is schools should plan on reopening,” Cuomo said in a call with reporters Saturday.

But he cautioned that one variable will be the comfort level of parents -- and he said not all parents are in favor of opening. “So you open a school, you will have partial attendance, which will serve no one,” he said.

Police ended the protests in the center of the German capital, demanding that they disperse, because many of those taking part were not wearing masks or observing distancing rules. They said they would bring charges against the organizer. Protesters waved placards and chanted slogans including “The biggest conspiracy theory is the corona pandemic,” according to DPA.

“Yes demonstrations must also be possible in coronavirus times, but not like this,” Spahn said in a tweet. “Distancing, hygiene rules and masks protect us all.”

Spain Won’t Retaliate Against U.K. (10:07 a.m. NY)
