All times Eastern:Jan 13, 10:05 amOhio State University researchers discover new variantScientists at the Ohio State University’s Wexner Medical Center and College of Medicine announced Wednesday that they have discovered a new variant of the novel coronavirus.The new strain carries a mutation identical to the variant that was discovered in the United Kingdom late last year, but researchers said it likely arose in a virus strain already present in the United States. The researchers also reported the evolution of another U.S. strain that acquired three other gene mutations not previously seen together in SARS-Cov-2, the virus that causes COVID-19, according to a press release.The Ohio State University Wexner Medical Center has been sequencing the genome of SARS-Cov-2 viruses in patients with COVID-19 since March to monitor the evolution. The new variant was found in one patient from Ohio, and researchers do not yet know the prevalence of the strain in the population, according to the press release.Meanwhile, the evolving strain with the three new mutations has become the dominant virus in the state’s capital, Columbus, during a three-week period in late December and January.“This new Columbus strain has the same genetic backbone as earlier cases we’ve studied, but these three mutations represent a significant evolution,” Dr. Dan Jones, the study’s leader and vice chair of the Ohio State University’s division of molecular pathology, said in a statement. “We know this shift didn’t come from the U.K. or South African branches of the virus.”Like the U.K. strain, researchers said the mutations in the Columbus strain are likely to make the virus more infectious.“At this point, we have no data to believe that these mutations will have any impact on the effectiveness of vaccines now in use,” said Peter Mohler, a co-author of the study, chief scientific officer at the Ohio State University Wexner Medical Center and vice dean for research at the College of Medicine. “It’s important that we don’t overreact to this new variant until we obtain additional data.”The researchers will hold a press conference on the matter later Wednesday, according to the press release.Jan 13, 6:24 amJapan declares state of emergency in seven more prefecturesJapanese Prime Minister Yoshihide Suga declared a state of emergency in seven additional areas on Wednesday, as COVID-19 cases continued to climb.The latest state of emergency was declared for the prefectures of Osaka, Hyogo, Kyoto, Aichi, Gifu, Fukuoka, and Tochigi.The move comes one week after Suga declared a state of emergency in Tokyo and three neighboring prefectures due to rising infections and a growing death toll.A state of emergency declaration gives the governors of those respective regions the authority to ask residents for cooperation in efforts to curb the spread of the virus. There are currently no legal ramifications for non-compliance.Under the state of emergency, which takes immediate effect and is expected to end Feb. 7 for all 11 prefectures, Suga said governors will ask residents to refrain from dining out and to stay home after 8 p.m. unless for essential reasons. They will also ask companies to decrease the number of employees commuting to work by 70%.Suga said bars and restaurants will be asked to stop serving alcohol by 7 p.m. and to close by 8 p.m. Governors may disclose the name of the businesses that don’t comply, while those that do will be given 1.8 million Japanese yen ($17,000) per month.Spectator events will be limited to an audience of 5,000 people. Schools will not be asked to close, according to Suga.Suga’s predecessor, Shinzo Abe, declared a nationwide state of emergency relatively early in the pandemic in April, which lasted for a month. At that time, residents were asked to reduce person-to-person contact by 80% and to practice “jishuku,” or “self-restraint,” by staying at home and closing non-essential businesses.The Japanese Ministry of Health, Labor and Welfare registered 4,521 newly confirmed cases of COVID-19 as well as 51 additional deaths from the disease on Tuesday, bringing the country’s cumulative total to 295,257 cases with at least 4,144 deaths.Jan 13, 4:42 amUS sees deadliest day yet from COVID-19There were a record 4,327 new deaths from COVID-19 registered in the United States on Tuesday, according to a real-time count kept by Johns Hopkins University.Tuesday’s tally overtakes the country’s previous all-time high of 4,194 fatalities from the disease, which were registered on Jan. 7, Johns Hopkins data shows.An additional 215,805 new cases of COVID-19 were also confirmed nationwide on Tuesday, down from a peak of 302,506 newly confirmed infections on Jan. 2. It’s the eighth consecutive day that the country has reported more than 200,000 new cases, according to Johns Hopkins data.COVID-19 data may be skewed due to possible lags in reporting over the holidays followed by a potentially very large backlog.A total of 22,846,808 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 380,796 of them have died, according to Johns Hopkins data. The cases include people from all 50 U.S. states, Washington, D.C., and other U.S. territories as well as repatriated citizens.Much of the country was under lockdown by the end of March as the first wave of the pandemic hit. By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country’s cases then hovered around 20,000 for a couple of weeks before shooting back up over the summer.The numbers lingered around 40,000 to 50,000 from mid-August through early October before surging again to record levels, crossing 100,000 for the first time on Nov. 4, then reaching 200,000 on Nov. 27 before topping 300,000 on Jan. 2.Jan 13, 3:57 amTexas surpasses two million total casesTexas has become the second U.S. state to have a total of more than two million diagnosed cases of COVID-19.The Lone Star state surpassed the grim milestone late Tuesday, with a cumulative tally of 2,014,645 confirmed cases. California currently has 2,795,978, according to a real-time count kept by Johns Hopkins University.Copyright © 2021, ABC Audio. All rights reserved.
