U.S. Cases Increase 0.9%; California, Arizona Slow: Virus Update

(Bloomberg) —

California and Arizona reported positive trends on new cases after battling a surge in infections last month. New Jersey, concerned about recent violations of social-distancing rules among young revelers, reduced crowd limits for indoor parties.

Eli Lilly & Co. will begin testing its Covid-19 antibody drug in nursing homes, a treatment with potential to protect vulnerable groups that vaccines may not cover. Global coronavirus cases surpassed 18 million, with the pandemic now adding a million infections every four days.

Iran’s virus death toll may have been almost three times larger than official counts, the BBC reported, while Hong Kong said it had the fewest number of new cases since July 22.

Engineered decoys trap virus in test tube study; healthcare workers at high risk even with protections

By Nancy Lapid

(Reuters) – The following is a brief roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.

Engineered decoys trap virus before it can enter cells

The new coronavirus enters cells by attaching to a protein on the cell membrane called the ACE2 receptor. Scientists have now developed a decoy version of ACE2 that lures the virus and traps it, preventing it from infecting human lung cells in test tubes. “We have engineered our ACE2 Trap to bind 100 to 1,000 times tighter to the virus than normal ACE2 that is on victim cells. This provides even more potent blockage that is comparable to neutralizing antibodies,” Dr. James Wells of the University of California

Virus curfew imposed on Australia’s second-biggest city

Australia imposed an overnight curfew on its second-biggest city Sunday and banned people from moving more than five kilometres from home in a bid to control a growing coronavirus outbreak that is infecting hundreds daily.

Declaring a “state of disaster”, Victoria Premier Daniel Andrews said Melbourne would move to Stage 4 restrictions until September 13 given “unacceptably high” levels of community transmission.

The harshest rules in Australia to date will see city residents face a curfew from 8 pm to 5 am for the next six weeks. Only those carrying out essential work, or seeking or providing care, will be allowed out.

“The time for leniency, the time for warnings and cautions is over,” Andrews said.

“If you are not at home and you should be, if you have the virus and are just going about your business, you will be dealt with harshly. Lives are at stake.”

One of the first school districts in the country to reopen its doors during the coronavirus pandemic did not even make it a day before being forced to grapple with the issue facing every system actively trying to get students into classrooms: What happens when someone comes to school infected?

On the first day of classes Thursday, a call from the county health department notified Greenfield Central Junior High School in Indiana that a student who had walked the halls and sat in various classrooms had tested positive for the coronavirus.

Administrators began an emergency protocol, isolating the student and ordering everyone who had come into close

How many COVID-19 virus mutations are there?

The quick answer is a lot, but only one strain is concerning doctors right now: The science world has been buzzing with troubling news that the virus that causes COVID-19 may have mutated in such a way to make it more transmissible. A preliminary study from April 30 and another on June 12 suggested that the virus variant, called G614, harbors a feature that allows the virus to more easily infect cells and therefore spread more rapidly. The concern rose even more last week when Anthony Fauci, MD, head of the National Institute of Allergy and Infectious Diseases (NIAID), broached the idea during an online chat. Here are 13 ways this coronavirus pandemic is different from all epidemics in history.

A mutation that speeds up COVID-19’s spread might explain why the virus—known as SARS-CoV-2—has so rapidly moved through North America and Europe, where the G614 mutated version is predominant. The

Florida Has Record Deaths Again; Vaccine Progress: Virus Update

(Bloomberg) — Almost 10,000 people in the U.K. have been given an experimental Covid-19 vaccine from AstraZeneca Plc and the University of Oxford, a key step toward finding a shot that will help control the pandemic. Johnson & Johnson wants to start Phase 3 trials of its vaccine in September.

The U.S. economy suffered its sharpest downturn on record and the number of Americans filing for unemployment benefits rose for a second straight week. President Donald Trump raised the notion of delaying the next U.S. election scheduled for November.

Mexico’s economy also sank the most on record. Germany reported the highest number of new cases in about six weeks and its economy shrank by a record 10% in the second quarter.

Germany reported the highest number of new coronavirus cases in about six weeks, with the rate for new infections above a key threshold for a sixth consecutive day. Its economy shrank by 10% in the second quarter.

The number of Americans killed by the virus exceeded 150,000 on Wednesday as death tolls surged to records in some of the hardest-hit and most populous states. Mexico’s economy sank the most on record.

Ga. Democratic Senate candidate’s wife has virus

ATLANTA — Georgia Democratic Senate candidate Jon Ossoff says he’s in isolation with his wife, who contracted COVID-19.

The 33-year-old candidate said his wife, Dr. Alisha Kramer, has mild coronavirus symptoms and that he’s showing symptoms, too. He said he was tested Saturday and is awaiting results while self-quarantining.

Ossoff’s campaign communications director, Miryam Lipper, said on Twitter that he “has not held or participated in an in-person campaign event in over a month and will remain in isolation until medical professionals clear both him and” his wife.

Ossoff, a young media executive known for breaking fundraising records during a 2017 special election loss for a U.S. House seat, is in a competitive race against Republican U.S. Sen. David Perdue. The 70-year-old incumbent is a close ally of President Donald Trump and is seeking a second term in November.
