(Bloomberg) -- The Hong Kong government said an airport cleaner with no recent travel history has tested preliminary positive for Covid and is suspected to carry the omicron variant. The island’s previous imported cases of omicron all had prior travel history. 

Merck & Co.’s Covid-19 pill was cleared by U.S. regulators, the second new treatment option approved in as many days in an expanding arsenal to fight the pandemic. But just like testing sites and vaccines, treatment pills will be in short supply for months until production can increase.

New York’s daily coronavirus cases nearly doubled in less than a week when the state broke the previous record. Meanwhile, Morgan Stanley told workers to wear masks and limit big meetings.

Australia Speeds Up Boosters (5:55 p.m. N.Y.)

Australia has brought forward implementing third-dose booster shots for Covid-19 as the nation battles outbreaks of the omicron variant.

From Jan. 4, Australians will be be able to get their booster shot four months after receiving their second dose, from five months currently, Health Minister Greg Hunt said in Canberra. From Jan. 31, the time limit will be cut again to three months.

“These dates have been set out of an abundance of caution to give Australians early continued protection,” Hunt said. About 91% of Australians aged 16 and over have had two jabs, he said.

New York’s daily Covid-19 cases rose to 38,835 on Thursday -- nearly doubling in less than a week when the state broke the previous record of 19,942 new cases set in January, according to state data. 

Of the 324,786 people who were tested, 12% were positive as the omicron variant washes over the state. Omicron comprised 62% of sequenced cases from New York between Dec. 9 and Dec. 22.

Hospitalizations aren’t rising as fast as cases but they are starting to climb steadily. Hospitalizations increased by 18% to 4,534 over the last week. Deaths have remained steady with about 60 New Yorkers dying from Covid per day.

Ecuador Imposes Vaccine Mandate (3:25 p.m. NY)

Ecuador’s Health Ministry has ordered the inoculation of people 5 years of age and older against Covid-19 in a bid to ward off the threat of a further spike of infections, forging ahead of the rest of the region. While a similar order is bogged down in courts in Costa Rica, Ecuador’s Health Ministry said that the decision is backed by the country’s health law. 

The government has enough vaccine doses available to enforce the move, part of a wide range of measures from the banning of large religious processions to the shuttering of brothels issued this week. Currently, 12.4 million people, or 77%, of the target population have been fully vaccinated.

Morgan Stanley Tells Workers to Mask Up (12:05 p.m. NY)

Morgan Stanley told employees who have to be in the office through the first two weeks of January to wear face coverings when not at their desks and limit large in-person meetings.

“This guidance applies to all locations (even those where everyone is fully vaccinated),” the New York-based bank said in a memo to staffers this week. “Masking is always encouraged for anyone who is at increased risk or who has a household member who is unvaccinated or at increased risk.”

A Morgan Stanley representative didn’t immediately respond to a request for comment.

Omicron Hospital Risk as Much as 70% Lower (12:01 p.m. NY)

Omicron appears to be less severe but more contagious than any other Covid-19 strain to date, the U.K. government said, as daily infections soared to another new record close to 120,000. 

An individual with omicron is 50% to 70% less likely to be admitted to hospital, compared with the delta strain, the U.K. Health Security Agency said Thursday. They are also between 31% and 45% less likely to attend emergency departments with omicron than with delta.

However, data from the HSA also showed that while a booster improves protection, it starts to wane more rapidly than with delta, and is 15% to 25% lower from 10 weeks after the third dose. 

Italy Infections at Record (11:40 a.m. NY)

Italy recorded the highest number of coronavirus cases since the beginning of the pandemic. The first country in Europe to move into lockdown last year reported 44,595 cases on Thursday, up from 36,293 a day earlier. Patients in intensive care units rose by 13 to 1,023, still well below the peak of more than 4,000 last year.

U.K. Case Record Pressures Johnson (11:20 a.m. NY)

U.K.  cases surged to a record for a second day, piling pressure on Prime Minster Boris Johnson as he considers whether to tighten pandemic regulations after Christmas.

A total of 119,789 new cases were logged on Thursday, according to data published on the government’s coronavirus dashboard. That’s more than double the rate seen at the start of the month, and an increase of more than 10,000 on Wednesday’s caseload -- which had been a daily record.

New Wave Taking Hold in U.S. (11:00 a.m. NY)

Another wave of Covid infections is taking hold in the U.S., powered by the fast-spreading omicron variant. On Wednesday, daily cases topped 250,000 for the second time this week, data compiled by Johns Hopkins University and Bloomberg show.

Even so, the hospitalization rate in the nation has been relatively stable in recent days. Preliminary studies from overseas show omicron may be less likely to land patients in the hospital than the delta strain.

Serbia Finds First Omicron Case (10:50 a.m. NY)

Serbia detected its first omicron case on Thursday after health authorities said the strain will inevitably spread to the Balkan country. Serbia’s rate of new infections has been declining this month but the government has warned that another wave of Covid cases is possible.

Yale Delays Start of Term (9:40 a.m. NY) 

Yale University is delaying the start of the spring semester and moving the first few weeks of classes online as the Covid-19 omicron strain spreads. The school’s spring break will also be shortened by one week.

After a relatively quiet start to the fall semester, several colleges including Harvard, Stanford and Duke have announced plans to begin the term starting in January online.

Merck Pill Gets U.S. Clearance (9:23 a.m. NY)

Merck & Co.’s Covid-19 pill was cleared by U.S. regulators, giving high-risk patients another at-home treatment option at a time when the omicron variant is causing cases to surge.

The drug, molnupiravir, received emergency authorization on the heels of Pfizer Inc.’s competing pill that was cleared Wednesday, Paxlovid. Together, the treatments promise to provide a new way to keep a sharp rise in infections from overwhelming U.S. hospitals.

Molnupiravir, developed by Merck with partner Ridgeback Biotherapeutics LP, is intended to treat Covid in non-hospitalized people 18 and older at risk of developing severe illness. A study showed it reduced the risk of hospitalization or death among adults with mild to moderate disease by 30%. 

Slovenia Tightens Restrictions (9:19 a.m. NY)

Private gatherings on Christmas and New Year’s will be limited to family members of up to three different households.

German ICU Occupancy Seen Surging (9:13 a.m. N.Y.)

Germany may see 8,000 Covid-19 patients in intensive-care units simultaneously next spring, Spiegel magazine reported, citing calculations by the Max-Planck-Institut. Currently, the country has about 4,400 ICU patients with Covid, and 85% of all intensive care beds occupied.

Three Sinovac Doses Fails to Protect (6 p.m. H.K.)

Two doses and a booster of the vaccine made by China’s Sinovac didn’t produce sufficient levels of neutralizing antibodies to protect against the omicron variant, a laboratory study found.  

A booster shot from Germany’s BioNTech SE significantly improved protective levels of antibodies against omicron for those who are fully immunized with the vaccine known as CoronaVac, according to the study from the University of Hong Kong and the Chinese University of Hong Kong. 

AstraZeneca Booster Works Against Omicron (5:45 p.m. HK)

The vaccine, created by Astra and Oxford, saw neutralizing antibodies increase to similar levels as those after two doses against the delta variant with a booster shot, the company said. A third dose produced higher levels of neutralizing antibodies than those found in individuals who had recovered naturally from the alpha, beta and delta strains.
