WASHINGTON — The so-called COVID-19 delta variant which was first detected in India now represents more than 20% of coronavirus infections in the U.S. in the last two weeks, or double what it was when the Centers for Disease Control last reported on the variant’s prevalence.

Dr. Anthony Fauci, the nation’s top infectious disease expert, warned that the U.S. could be following the United Kingdom’s course, where the variant has become the dominant strain due to rapid spread among youth.

Fauci says indications are that the COVID-19 vaccines remain effective against the variant.

The variant is accounting for half of new infections in the regions that include Iowa, Kansas, Missouri, Nebraska, Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming.

HERE'S WHAT ELSE IS HAPPENING:

HONOLULU — Uncertainty remains about when Hawaii will drop its requirement for vaccinated arriving travelers to have a negative coronavirus test to avoid quarantine.

Hawaii Lt. Gov. Josh Green wants the state to drop the testing requirement for fully vaccinated travelers ahead of the July 4th holiday, but Gov. David Ige is reluctant.

Ige would not commit to dropping the travel test during a Monday news conference. The governor said earlier this month that testing requirements for vaccinated domestic travelers would end once 60% of Hawaii residents are fully vaccinated.

Lt. Gov. Josh Green said there could be confusion and conflict if the state doesn’t drop the requirements soon.

JERUSALEM — Israel’s prime minister says the country is in the grip of a “new outbreak” of the coronavirus after a spike in cases in the past week, most of them minors with the highly infectious Delta variant of COVID-19.

Naftali Bennett said Tuesday after touring Israel’s main international airport that masks would be mandatory in Ben Gurion Airport and there would be more stringent testing of incoming travelers.

“We made an initial decision to treat this like a new outbreak, and our aim is to sever it,” he said. Bennett called on Israelis to avoid all non-essential summer travel abroad.

Israel’s Health Ministry reported 125 new coronavirus cases Tuesday, the highest daily number since late April. Over 55% of the country’s 9.3 million citizens have received two vaccine doses, but Bennett said several of the new cases reported were in vaccinated individuals.

MOSCOW – The mayor of Moscow announced new coronavirus restrictions on Tuesday, saying that “the situation with the coronavirus remains very difficult” in the Russian capital.

The country’s state coronavirus task force reported 6,555 new COVID-19 cases in Moscow on Tuesday and 16,715 new infections across Russia, both tallies twice as high as a month ago.

Moscow Mayor Sergei Sobyanin banned all entertainment and sports events at which more than 500 people are present.

Starting next Monday, all restaurants, cafes and bars in Moscow will only allow in customers who have been vaccinated against COVID-19, recovered from the virus within the past six months or can provide a negative coronavirus test carried out within 72 hours prior to the visit. To prove their eligibility, customers will need to obtain a QR code at one of several government websites.

Coronavirus infections surged in the Russian capital two weeks ago, prompting the city authorities to order mandatory vaccinations for workers in retail, education and some other service sectors. Russians have been widely resistant to vaccinations and only less than 13% of the population has received at least one shot of a coronavirus vaccine.

She also told Scottish lawmakers that changes to current restrictions will be postponed by three weeks to July 19 as a result of a sharp spike in new infections that are largely due to the delta variant first identified in India.

She said 2,167 cases have been recorded in Scotland in the past 24 hours, the highest level since Jan. 8 when the U.K. as a whole was in the midst of a catastrophic second wave of the pandemic.

The U.K. as a whole recorded 11,625 new cases on Tuesday, the highest daily figure since Feb. 19.

She said her government will make a final assessment nearer the time to see whether this could include the lifting of social distancing rules both indoors and out. l as outdoors.

ISTANBUL — Turkey’s president has announced the country’s first local vaccine in development against COVID-19 would be called TURKOVAC.

The first dose of the vaccine’s third phase trial was administered to a male volunteer Tuesday in a videoconference by the health minister, professors and Turkey’s president. The health minister said Phase 1 and 2 trials showed the vaccine’s safety and immune response.

TURKOVAC is using an “inactivated virus” technology and was developed at Erciyes University. Other vaccine developments continue in Turkey. Turkish President Recep Tayyip Erdogan has said it is imperative to have a local vaccine that Turkey would use in the country and export to others.

Turkey is currently using vaccines from China’s Sinovac and Pfizer-BioNTech. Russia’s Sputnik V will also be used. More than 43,5 doses have been administered with the age category lowered to 25 on Tuesday.

Health Minister Fahrettin Koca said the vaccine is the “pride of the nation.”

PORTLAND, Maine — A program to help the U.S.’s bus companies survive the coronavirus pandemic that was championed by a Maine senator is now accepting applications.

Republic Sen. Susan Collins co-wrote the Coronavirus Economic Relief for Transportation Services grant program and said this week that the program is now open. The program is slated to provide $2 billion in coronavirus relief to bus, motorcoach and other passenger vessel companies.

The pandemic has hit the nation’s approximately 3,000 private bus lines hard. Nearly all of them were shut down in the early stages of the pandemic and many have struggled to recover since.

“Bus and motorcoach companies, ferries, and tour boats sustain good-paying jobs and provide critical transportation services. The COVID-19 pandemic took an enormous toll on these businesses, many of which are small and family owned,” Collins said.

Collins co-authored the proposal with Democratic Sen. Jack Reed of Rhode Island. The senators said that every bus and vessel company that meets eligibility criteria and submits a completed application will receive a grant.

AMSTERDAM — The European Union’s medicines regulator has approved two new manufacturing sites for the COVID-19 vaccine developed by BioNTech and Pfizer.

The move announced Tuesday by the European Medicines Agency will help increase production of the vaccine that has formed the backbone of many European nations’ vaccination programs.

The European Center for Disease Prevention and Control says that 242.6 million doses of the Pfizer-BioNTech vaccine have been distributed to European nations and nearly 223 million shots have been administered.

The EMA says its human medicines committee approved a site in Reinbek, Germany, that is operated by Allergopharma and another in the Swiss town of Stein that is operated by Novartis Pharma.

Last month, the EMA recommended expanding the use of the Pfizer-BioNTech vaccine to children aged 12-15.

Limits on indoor gatherings like weddings and funerals are gone. So is a broad requirement that the unvaccinated be masked indoors. Michigan is among the last states to lift capacity caps, which has frustrated the business community.

MANILA, Philippines — The Philippine president has threatened to order the arrest of Filipinos who refuse COVID-19 vaccination and told them to leave the country if they would not cooperate with the efforts to contain the pandemic.

President Rodrigo Duterte, who is known for his public outbursts and brash rhetoric, said in televised remarks Monday night that he has become exasperated with people who refuse to get immunized then help spread the coronavirus.

“Don’t get me wrong. There is a crisis being faced in this country. There is a national emergency. If you don’t want to get vaccinated, I’ll have you arrested and I’ll inject the vaccine in your butt,” Duterte said.

“If you will not agree to be vaccinated, leave the Philippines. Go to India if you want or somewhere, to America,” he said, adding he would order village leaders to compile a list of defiant residents.

A human rights lawyer, Edre Olalia, raised concerns over Duterte’s threat, saying the president could not order the arrest of anybody who has not clearly committed any crime.
