The decision to exclude Sweden, from the lifting of travel restrictions between Nordic countries Finland, Denmark and Norway, following the coronavirus pandemic, "has created wounds that will take time to heal," the country's Foreign Minister Ann Linde told CNBC.

A decision not to implement a strict lockdown like its neighbors has meant that Sweden, which has seen a far higher number of coronavirus cases and deaths, has been left out of an easing of travel restrictions between the countries.

Minister Ann Linde said "people that have been very used to working as if there were no borders, have been given a very clear wake-up call that different nations (are being treated differently) and I think this will, in many people, create wounds that could be difficult to heal." Holly Ellyatt

9:06 a.m. Beijing time China's capital city had gone more than 50 days without domestically transmitted cases when a new cluster of cases emerged late last week, and were traced back to a major wholesale produce market in Beijing.

As of Tuesday, China's National Health Commission reported another 31 confirmed cases of local transmission in Beijing.

The city has started to reinstate some restrictions that had been relaxed in recent weeks. While these measures are less strict than the blanket bans imposed in February, they are still likely hit economic activity again. Evelyn Cheng, Christine Wang

7:20 p.m. ETAmazon is testing a wearable device at its Seattle-area warehouse that lights up and beeps if workers aren't following social distancing rules, according a memo obtained by CNBC.

Starting Wednesday, the device will be rolled out at Amazon's Kent, Washington facility. The device is a clear plastic sleeve with a clip that features an LED light and audio system, according to a memo seen by CNBC.

When workers are too close to one another, the wearable emits a loud beeping noise and the light flashes.

An Amazon spokesperson confirmed the company recently began a small-scale pilot of the wearable device at one of its warehouses. The spokesperson added that the company will use feedback from teams testing the device "to continue to iterate." It comes as Amazon has also experimented with cameras equipped with social distancing software. On Tuesday, the company announced it's rolling out "Distance Assistants" at a handful of facilities across the U.S. A camera is hooked up to a monitor and a local computing device that alerts users as they walk by whether they're maintaining proper distancing.Annie Palmer

6:25 p.m. ET Dexamethasone, a steroid that one study says effectively reduced death among Covid-19 patients, is a "good first step" to finding a cocktail of drugs that can treat the disease, Oxford University professorMartin Landray told CNBC.

"It's very likely that we'll end up with a situation where a combination of drugs are used, just as we see in HIV, just as we see in heart disease, in many other areas of medicine," said Landray, who co-led the study that found the drug to improve survival among patients. "But this is the first step. It's a good first step."

The drug is cheap, widely available in most countries and appears to be effective in treating some symptoms of the disease, Landray said. He said he hopes that researchers find other drugs that also attack other aspects of the virus and the disease it caused.Will Feuer

5 p.m. ETTexas Gov. Greg Abbottsaid that the state has seen an increase in coronavirus cases since Memorial Day most likely due to people who didn't follow recommended social distancing practices.

The state reported an additional 2,622 cases of Covid-19 on Tuesday, a new daily high, he said. Abbott pointed to an increase in testing in state nursing homes, correctional facilities as well as some reporting delays as reasons behind jumps in daily case numbers.

However, he added that some counties have reported higher positivity rates stemming from people under 30 years old, indicating they may be going to "bar-type settings" or were infected at Memorial Day celebrations, Abbott said. "We think we can also accurately say there has been an increase especially beginning around the Memorial Day time period and going through a few weeks after that an increase in people testing positive because they may not be practicing all these safe standards," he said. He reminded residents to continue wearing face masks, washing their hands and maintaining a distance from other people.Noah Higgins-Dunn

1:04 p.m. ET Texas Covid-19 hospitalizations are up roughly 66% since Memorial Day as the state continues to reopen.

There are now 2,518 patients hospitalized with a coronavirus infection across the state's hospitals, according to data from the Texas Department of State Health Services. At least 10 states in total are showing a rise in hospitalizations, according to a CNBC analysis of data from theCOVID Tracking Project.

In recent weeks, some state and federal leaders have downplayed a recent rise in cases and hospitalizations across the U.S., tying it to an increased in testing. Infectious disease specialists note that the U.S. and other parts of the world will likely continue to see a rise in cases until there is a proven drug or effective vaccine.Berkeley Lovelace Jr.

12:28 p.m. ET Americans who can't afford the vaccine to prevent Covid-19 will get it for free, Trump administration officials announced.

Some commercial insurers have also expressed "eagerness" to cover the vaccine without a co-pay, a senior administration official told reporters during a press briefing, meaning those with insurance may also not have to pay anything out of pocket.

U.S. health officials and researchers have been fast-tracking work on vaccine development, aiming to produce 300 million doses of a potential vaccine by January. Because of the pandemic, U.S. officials are investing in multiple stages of research even though doing so could be for naught if the vaccine ends up not being effective or safe.Berkeley Lovelace Jr.

11:40 a.m. ET Dexamethasone, a cheap and widely available steroid, could have an "immediate impact" on how doctors treat Covid-19 patients, former Food and Drug Administration Commissioner Dr.Scott Gottliebsaid.

A new study found the drug to effectively improve survival among severely sick Covid-19 patients.

"It's going to probably have an immediate impact on what doctors are doing in the ICU setting," Gottlieb said on CNBC's "Squawk Box" in response to the news."This is an important finding. It's going to change dogma."

The researchers of the study said it is the first drug to appear to improve survival among Covid-19 patients. There are still notreatments approved by the FDA to treat the disease, though Gilead's remdesivir has received an emergency use authorization.Will Feuer

11:23 a.m. ET Tenet Healthcare says the spike in Covid-19 cases in states like Arizona is not impeding the rebound in elective surgery at its hospitals, which are back to 95% of pre-coronavirus levels this month.

"We're busy with Covid, but we're not overwhelmed.... and we've put a lot of focus on really insuring Covid care zones are being separated from coded safe zones, and communicating that actively into the community and to the physician community, in particular, so they feel comfortable," said Tenet COO Saum Sutaria on an update call with analysts.

Sutaria noted that new Covid-19 patients in markets where cases are rising tend to be younger, in their mid-30s to mid-60s, and require less intensive care treatment.

Tenet shares rose nearly 6% in opening trade but gave up those gains late morning.Bertha Coombs

9:50 a.m. ET One in five people worldwide isat risk of developing severe cases of Covid-19, scientists have estimated.

A team of researchers from the U.S., the U.K. and China estimated that 1.7 billion people or 22% of the global population are at "increased risk" of developing severe symptoms if infected with the coronavirus.

People were considered to be at increased risk if they had one or more chronic health conditions associated with greater vulnerability to the virus, such as diabetes or cardiovascular disease.

In North America, 28% of the population, or 104 million people, had at least one underlying condition that put them at increased risk of developing severe Covid-19 if they caught the virus, according to the study.Chloe Taylor

9:41 a.m. ET Treating Covid-19 patients with the generic steroid dexamethasone cut death rates by about a third for those with the most serious cases of the virus, according to data from a UK-led clinical trial.

9:22 a.m. ET This year's CNBC Disruptor 50 listincludes at least 18 companies that say demand for their core products has more than doubled since the coronavirus crisis unleashed itself across the world. That's because many use artificial intelligence and machine learning, which are speeding the development of medical treatments to fight the virus.

Others are in the health-technology field supporting at-home testing, such as Healthy.io, which provides FDA-approved remote urinalysis, and Heal, a six-year-old start-up that provides at-home doctor visits through telemedicine.

C3.ai, a company that is so defined by artificial intelligence that it changed its name from C3 IoT a few years ago, has taken a leading role in using the technology to fight Covid-19.

The three-time Disruptor 50 company teamed up with Amazon Web Services in April to create a Covid-19 "data lake," which unifies data sets, updates them in real-time and offers researchers a clearer starting point for generating usable insights.

Tempusbuilt a drug discovery-and-development platform designed to be disease-agnostic. So when the pandemic hit, it was in a strong position to pivot and support efforts to slow the spread and to find short-term and long-term treatments.

Tempus brought a test to market in April and launched a research project examining 50,000 coronavirus-positive patients to find the most effective treatments and other insights. Lori Ioannou
