Coronavirus: What's happening around the world on Aug. 5

The latest:

• Total number of coronavirus deaths in Canada passes 9,000.
• Top court rules Brazil must protect Indigenous in pandemic.
• Former Colombian president Alvaro Uribe reportedlytests positive for coronavirus.
• Blood donor study suggests more than 120,000 Quebecers have been infected with coronavirus.
• Health Canada recalls more than 50 hand sanitizers in evolving list.
• First Alaska cruise of season cut short after passenger tests positive.
• Australia's Victoria state enacts strict lockdowns to curb coronavirus spread.
• Canadian federal ministers announce next steps to procure COVID-19 vaccine.
• 32 per centof Canadians may hold off on getting eventual vaccine, survey shows.

U.S. testing for the coronavirus is dropping even as infections remain high and the death toll rises by more than 1,000 a day, a worrisome trend that officials attribute largely to Americans getting discouraged over having to wait hours to get a test and days or weeks to find out the results.

An Associated Press analysis found that the number of tests per day slid 3.6 per centover the past two weeks to 750,000, with the count falling in 22 states. That includes places like Alabama, Mississippi, Missouri and Iowa where the percentage of positive tests is high and continuing to climb, an indicator that the virus is still spreading uncontrolled.

Amid the crisis, some health officials are calling for the introduction of a different type of test that would yield results in a matter of minutes and would be cheap and simple enough for millions of Americans to test themselves but would also be less accurate.

"There's a sense of desperation that we need to do something else," said Dr. Ashish Jha, director of Harvard's Global Health Institute.

Widespread testing is considered essential to containing the outbreak as the United Statesapproaches a mammoth five million confirmed infections and more than 157,000 deaths out of over 704,000 worldwide.

Testing demand is expected to surge again this fall, when schools reopen and flu season hits, most likely outstripping supplies and leading to new delays and bottlenecks.

Some of the decline in testing over the past few weeks was expected after backlogged commercial labs urged doctors to concentrate on their highest-risk patients. But some health and government officials are seeing growing public frustration and waning demand.

In Iowa, state officials are reporting less interest in testing, despite ample supplies. The state's daily testing rate peaked in mid-July but has declined 40 per centin the last two weeks.

"We have the capacity. Iowans just need to test," Gov. Kim Reynolds said last week.

The number of confirmed infections in the U.S. has topped 4.8 million, with new cases running at nearly 60,000 a day on average, down from more than 70,000 in the second half of July.

Chicago's mayor on Wednesday announced that the nation's third-largest school district will not welcome students back to the classroomafter alland will instead rely only on remote instruction to start the school year.

The city's decision to abandon its plan to have students attend in-person classes for two days a week once the fall semester starts Sept. 8 came amid strong pushback from the powerful union representing Chicago teachers.

When Chicago officials announced their hybrid-learning plan last month, they said it was subject to change depending on families' feedback and data tracking the spread of the coronavirus. On Wednesday, Mayor Lori Lightfoot attributed the change in plans to a recent uptick in confirmed cases of COVID-19 in the city.

Meanwhile, New York City will put up COVID-19 quarantine checkpoints at key entry points to ensure that incoming travellers from 35 states with outbreaks comply with the state's 14-day quarantine mandate, Mayor Bill de Blasio said on Wednesday.

The measure underscores the determination in what was once the pandemic's epicentreto prevent a resurgence of cases being seen elsewhere. While cases are down five per centnationally, they soared last week in Oklahoma, Montana, Missouri and 17 other states.

"Travellers coming in from those states will be given information about the quarantine and will be reminded that it is required, not optional," de Blasio told a news briefing. He added thatunder certain circumstances, fines for not observing the quarantine order could be as high as $10,000 US.

Also on Wednesday, the first cruise in an already decimated southeast Alaska cruise season came to an earlyend when a small ship carrying 36 passengers had to return to Juneau because one of the guests had tested positive for COVID-19.

Once the Wilderness Adventurer returns to Juneau, the city says all 36 guests will quarantine at a hotel, and the 30 crew members will quarantine on the ship.

The study, conducted by Hma-Qubec in collaboration with the Institut national de sant publique, confirmed that 2.23 per cent of 7,691 people who donated blood between May 25 and July 9 had contracted COVID-19.

Based on the sample data, the study extrapolates that 124,880 Quebecers aged 18 to 69 had been infected between the start of the pandemic andearly July. In the same time period, the study saidthat Quebec's Health Ministry had recorded fewer than 40,000 Quebecers ages 20 to 69 as confirmed cases.
