Roughly 162 patients were confirmed positive in the hospital, the mayor said. Hospitalizations have gone up, but not at the rate health officials were expecting.

Israel health officials recommend putting US on no-fly list
Starting Dec. 22, the U.S. could be on Israel's no-fly list due to high COVID infection rates. All travel from Israel to the U.S. will be banned, the Israeli government announced Sunday.
The Ministry of Health has recommended that the U.S., and nine other countries including Canada, be classified as "red list" countries. The decision now awaits final approval from the Knesset's Constitution, Law and Justice Committee.
Israeli citizens coming to Israel from the U.S. will have to go into full isolation, including those vaccinated or recovered. Non-Israeli citizens coming from the U.S. will not be allowed to enter Israel, officials said.
At the start of the weekly cabinet, Israel Prime Minister Naftali Bennett said the fact the country is in a "relatively good situation" is "not a coincidence." He attributed delaying the entry of the variant to Israel to travel bans. "What a pity that other countries did not do as we did," he said Sunday.
In addition to the U.S., Israel also will also move Belgium, Canada, Germany, Hungary, Italy, Morocco, Portugal, Switzerland and Turkey to the no-fly list this week on Dec. 22. Norway, France, Spain, Sweden and the UAE will be added to Israel's no-fly list at midnight Dec. 20.
There are 52 countries on Israel's red list.

Journalist traveling with Blinken tests positive for COVID-19 in Malaysia
A journalist traveling alongside U.S. Secretary of State Antony Blinken on his visit to Southeast Asia has tested positive for COVID-19 in Malaysia, according to U.S. Department of State spokesperson Ned Price.
Meanwhile, Blinken and his senior staff all tested negative for COVID-19 upon arrival in Kuala Lumpur on Tuesday night. The member of the traveling press pool who tested positive had last tested negative in Indonesia's capital, their previous stop, on Tuesday.
"The individual who tested positive will remain in isolation," Price said in a statement Wednesday, "and we will continue to adhere to and go beyond CDC guidance, including with our rigorous testing protocol, for the remaining traveling party."
Blinken has canceled a scheduled trip to Thailand "out of an abundance of caution" and will return home to the United States, according to Price.
"The Secretary expressed his deep regret to the Foreign Minister that he would not be able to visit Bangkok this week," Price said. "He explained that, in order to mitigate the risk of the spread of COVID-19 and to prioritize the health and safety of the U.S. traveling party and those they would otherwise come into contact with, the Secretary would be returning to Washington, D.C. out of an abundance of caution."
"The Secretary extended an invitation for the Foreign Minister to visit Washington, D.C. at the earliest opportunity and noted that he looked forward to traveling to Thailand as soon as possible," Price added. "They affirmed that they would use the upcoming engagements to further deepen the U.S.-Thai alliance."
The U.S. Embassy in Malaysia confirmed that the infected individual "was not involved and has not participated in any of Secretary Blinken's program in Kuala Lumpur."
"The sole member of the traveling party who tested positive is observing all requirements of the Ministry of Health," the embassy said in a statement Wednesday. "We confirm all other members of the party tested negative for COVID-19 upon arrival in Malaysia."
Blinken was in Indonesia on Tuesday, and the U.S. Embassy in Jakarta confirmed that no members of the traveling party tested positive for COVID-19.
All members of the U.S. delegation are required to be vaccinated against COVID-19 and undergo regular testing on trips.
