(Bloomberg) -- More disruption lies ahead as U.S. schools reopen. A single Florida county has almost 12,000 students in isolation or quarantine. Oregon mandated, a day after Washington State, that all teachers and school personnel must get vaccinated. New Jersey Governor Phil Murphy was expected to make a similar announcement, NJ.com reported. 

Three U.S. senators tested positive for Covid-19 despite being vaccinated, bringing to at least six the number of members of Congress to report recent infections.

International Business Machines Corp. is temporarily closing its offices in New York City amid rising Covid-19 cases, but the company stopped short of delaying plans to reopen other U.S. locations by September. Intel Corp., the world’s largest chipmaker, is offering employees $250 if they get vaccinated by the end of the year.

President Joe Biden defended his push to give booster shots to all Americans, countering criticism that the move is unfair to other nations that are still struggling to procure a first dose of vaccine.

The school also plans to push back the start of classes by two days to Aug. 25, officials said Thursday.

The district, which includes Tampa, has about 208,000 students who started school last week. After the rocky start to classes, the school board voted Wednesday to mandate masks for everyone except those who provide a doctor’s note. Previously, parents were able to unilaterally opt out of the mask requirement.

Georgia Bars Local Restrictions (3:43 p.m. NY)

Georgia Governor Brian Kemp signed an executive order Thursday prohibiting local governments from requiring masks or other Covid-19 protection measures at private businesses. He said the order was prompted by mask mandates in Atlanta and Savannah, both of which have been in place for weeks. Savannah Mayor Van Jones has also said he is considering limiting indoor crowd sizes.“Small business should not be punished by local governments just because they are trying to save their businesses and pay their workers,” Kemp said in a press briefing.Cases have been surging in Georgia: On Wednesday, hospital officials held a press conference to beg Georgians to get vaccinated, saying beds and ICUs were filling up, according to the Atlanta Journal Constitution.

Intel Offers $250 for a Shot (3:07 p.m. NY)

Pressure is mounting on New York City Mayor Bill de Blasio to reverse his stance on a virtual option for students. 

City schools, the largest district in the country, are set to reopen Sept. 13 fully in-person, five days a week, without the remote offering provided to kids last year. De Blasio has said the city will not offer a remote option and does not have a Plan B to offer virtual schooling in case rising coronavirus cases shutter schools again. 

“We are dealing with an evolving pandemic and we have younger students currently ineligible for the vaccine,” said Mark Treyger, chairman of the City Council education committee, who is is leading the effort to push the mayor’s office on a more flexible alternative.

Tennessee Running Out of ICU Beds (1:15 a.m. NY)

Tennessee intensive care beds are full in most metropolitan areas because of the wave of Covid-19 patients, state hospital officials said on Thursday. 

“These are the hospitals that normally accept transfers of the sickest patients from other hospitals and healthcare providers, so when these facilities are full, it affects the healthcare system statewide,” the Tennessee Hospital Association said in a statement. 

The association said that Covid hospitalizations rose almost eightfold between July 1 and Aug. 15, from fewer than 300 patients to more than 2,300. Almost all patients are unvaccinated, the statement said. 

Humana to Require Shots After FDA Nod (11:30 a.m. NY)

The mandate will apply to Humana employees and some contractors who work outside their homes, the health insurer said in an email to staff. That includes people who see patients directly, those who work in Humana facilities, and attend in-person meetings. 

Starting in September, workers who are unvaccinated will have to be tested regularly if they’re working outside their homes, the company said. “We’re not the first to require vaccination and expect others to follow in reducing the devastating impacts of this pandemic,” the company said in an email shared with Bloomberg News. The move follows an announcement yesterday by Cigna Corp. to require immunizations.

Michigan, Tennessee Lead U.S. Increases (11:20 a.m. NY)

U.S. cases jumped the most in Michigan, Tennessee and Minnesota during the week that ended Tuesday, the Centers for Disease Control and Prevention reported. While those states recorded the biggest percentage increases, their cases relative to population remain well below the prevalence in Mississippi, Louisiana and Florida, the top states in that category.

Missouri, an early hot spot of the delta variant, recorded an 8% decline in cases over the period, according to the CDC’s community spread report published Thursday.

Hospital admissions for Covid-19 nationwide increased 16% during the week through Monday compared to the previous week, and the number of intensive-care cases rose 25%, according to the report.

Boosters Make ‘Mockery of Vaccine Equity’ (9:41 a.m. NY)

The rollout of Covid-19 booster shots by a growing number of wealthy nations makes a “mockery of vaccine equity,” WHO Regional Director for Africa Matshidiso Moeti said. 

“High-income countries have already, on average, administered more than 103 Covid-19 vaccine doses per 100 people, whereas in Africa that number stands at six,” Moeti said. Nations from Israel to the U.S. have either started administering booster shots or plan to, while less than 2% of Africans are fully vaccinated against the virus.

Biden Defends Booster-Shot Push (9:19 a.m. NY)

President Joe Biden defended his push to give booster shots to all Americans, countering criticism that the move is unfair to other nations that are still struggling to procure a first dose of coronavirus vaccines.

In an interview with ABC’s George Stephanopoulos that aired Thursday, Biden said he and first lady Jill Biden would soon get their booster shots: “We got our shots all the way back in, I think, December. So it’s -- it’s past time.”

Biden’s health team announced Wednesday that, beginning in September, all Americans would be eligible for a booster eight months after their second shot of either of the Pfizer Inc. or Moderna Inc. vaccines.
