(CNN)As governments scramble to contain new surges of Covid-19, the World Health Organization announced on Monday that a new initiative will supply 120 million affordable, rapid antigen tests to low- and middle-income countries. The tests, which will cost just $5 and deliver results in 15 to 30 minutes, rather than hours or days, could save thousands of lives.

They also have the potential to transform the way governments react to the pandemic, enabling officials to more quickly detect and respond to outbreaks before they spread.”High-quality rapid tests show us where the virus is hiding, which is key to quickly tracing and isolating contacts and breaking the chains of transmission,” Tedros Adhanom Ghebreyesus, WHO director general, said. “The tests are a critical tool for governments as they look to reopen economies and ultimately save both lives and livelihoods.”The news, which came as the world eclipsed 1 million Covid-19 deaths, is a small ray of hope in the fight against the virus.Also on Monday, President Donald Trump announced a plan to ship 150 million rapid coronavirus tests purchased by the US federal government to states in the coming months, marking a pivot away from his previous claims that increased testing would lead to more cases.Read MoreYOU ASKED. WE ANSWEREDQ: What’s the difference between rapid diagnostic tests and other viral tests? A: Rapid diagnostic tests, which do not need to be sent to labs for analysis, can deliver results within an hour or less based on a quick swab of the nostrils. They look for antigens, or pieces of coronavirus proteins, and perform best when a person is tested in the early stages of infection when the viral load is highest.But those tests can be less accurate than the diagnostic tests being used most widely, which use a method called PCR — considered the “gold standard” for detecting the coronavirus. The PCR test looks for signs that the virus is in your body, by detecting the presence of its genetic material in a swab sample from your nose or throat. The test is time-intensive though, and it can take anywhere from a day to a week to get the results back from a laboratory. Send your questions here. Are you a health care worker fighting Covid-19?

WHAT’S IMPORTANT TODAYTurmoil plagues Trump’s pandemic response teams on eve of debatePresident Donald Trump heads into Tuesday’s first crucial debate with Joe Biden as the US government’s coronavirus mitigation effort is in turmoil, Stephen Collinson writes. In a sign of the discord plaguing the administration’s Covid-19 response, CDC Director Robert Redfield and Dr. Deborah Birx did not appear at Trump’s event on Monday announcing the rollout of rapid testing. But his new favored counselor, Dr. Scott Atlas — a neuroradiologist who joined the White House Coronavirus Task Force in August and has drawn the ire of public health officials who say he is telling Trump what he wants to hear about the pandemic — got a speaking role. Dr. Anthony Fauci, the government’s top infectious disease expert, who has been marginalized by Trump, was asked by CNN’s Brian Stelter at an event on Monday whether there was acrimony behind the scenes. “Most are working together. I think you know who the outlier is,” Fauci said.Pre-Election Day push for stimulus deal is underwayHouse Speaker Nancy Pelosi and Treasury Secretary Steven Mnuchin, who have cut several major deals during the pandemic, are trying one final time to ease a bitter standoff on Capitol Hill over a pre-Election Day package to provide relief to millions of Americans reeling from the economic crisis.Pelosi and Mnuchin have spoken several times in recent days, including Monday night, and plan to again on Tuesday. And while most on Capitol Hill are deeply skeptical a deal can be reached, both Pelosi and Mnuchin have aligned interests: The speaker is facing growing pressure from vulnerable House Democrats, particularly freshmen, to cut a deal immediately, while President Donald Trump wants a legislative accomplishment to tout in the final weeks of the campaign. l FDA pauses Inovio’s vaccine trialBiotechnology company Inovio’s planned Phase 2/3 coronavirus vaccine trial has been put on a partial hold, the company announced on Monday. The US Food and Drug Administration notified Inovio that it has additional questions about its planned Phase 2/3 trial of the vaccine candidate INO-4800, including questions about the device to be used as part of delivering the vaccine in the trials. This partial clinical hold is not due to any adverse events, the company said. Some context: Inovio’s Covid-19 vaccine is being funded, in part, by the US Department of Defense, the Bill & Melinda Gates Foundation, and The Coalition for Epidemic Preparedness Innovations. The company has not received funding from Operation Warp Speed, the Trump administration’s initiative to fast-track the development and delivery of a Covid-19 vaccine.ON OUR RADARA former top adviser to Vice President Mike Pence has said the CDC was pushed by the administration to play down the risks of the coronavirus pandemic in reopening schools for in-person classes.
