Among the states that have reported the most new cases in the past seven days are Wisconsin, Idaho, South Dakota, Iowa, and Kansas, which are also reporting a coronavirus positivity rate of over 15 percent.
The positivity rate is the percentage of all tests given that test positive for the coronavirus.
The World Health Organization (WHO) advised governments in May that positivity rates should remain stable at 5% or less for at least two weeks before business reopens. A total of 27 states and Puerto Rico have rates above that level, according to JHU.
But some states are still seeing improvements. Maine, Vermont, Massachusetts, and New York all have positivity rates below 1
The formula for reducing deaths and cases
Smart testing and measures such as walking away, avoiding crowds, wearing masks, and hand washing are key to flattening the virus curve, Adm. Brett Giroir, a member of the White House coronavirus task force, told CNN’s Jake Tapper on Sunday.
“We are working every day. We have a formula to reduce deaths, reduce cases, but we must all be disciplined and diligent to make sure we obey every single day,” he said.
In response to the coming heartbreaking milestone of 200,000 coronavirus deaths, Giroir said “every death is a tragedy” and the task force is working every day to bring them down.
The CDC acknowledges that the coronavirus spreads through the air
The guide previously stated that Covid-19 was primarily thought to spread among people within 6 feet of each other and through respiratory droplets “produced when an infected person coughs, sneezes or talks.”
The guide, updated on Friday, still says Covid-19 is commonly spread among people in close contact with each other. But he also says the virus is known to spread through respiratory droplets “produced when an infected person coughs, sneezes, sings, talks or breathes.”
Infection can occur if the particles are inhaled “into the nose, mouth, airways and lungs,” the guide says.
“There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances greater than 6 feet (for example, during choir rehearsals, in restaurants, or in dance classes. fitness), “the page now says. “In general, indoor environments without good ventilation increase this risk.”
Donald Milton, a professor of environmental health at the University of Maryland who studies how viruses are transmitted, told CNN that the CDC’s new language was a “major improvement.”
Milton was one of the lead authors of a July letter signed by 239 scientists. They urged the World Health Organization to be more open to the likelihood that people could contract the virus from airborne droplets. The WHO later released a report detailing how coronavirus can pass between people, including through the air during some medical procedures and possibly in crowded indoor spaces.
“I am very encouraged to see that the CDC is paying attention and moving with science. The evidence is piling up,” Milton wrote in an email to CNN.
Dr. Abdul El-Sayed, an epidemiologist and public health expert, told CNN’s Wolf Blitzer on Sunday that the guide formalizes the CDC’s previous recommendations.
“What it means to people is that those masks are of paramount importance,” he said. “They are the most important way to stop those aerosols from leaking out of our mouth and nose and then into other people’s mouths or noses.”
The study finds further links between the pandemic and mental health
As Covid-19 intensified in the United States, stress and depression levels have also intensified, according to a study published in the journal Science Advances.
The study of over 6,500 people found that several factors may have made people’s stress worse.
The biggest risk for depression symptoms was a pre-existing mental health diagnosis before the pandemic, the researchers found.
But symptoms of stress and depression were also associated more with personal exposure rather than public outreach, suggesting that “concerns about contracting the disease outweighed concerns about pandemic-related disruptions in daily life,” the researchers said.
“About a quarter of the sample (23.5 percent) reported having been exposed to COVID-19 (for example, symptoms were diagnosed),” the researchers wrote in the report released Friday.
Employment also had a big impact, with those who lost their jobs suffering the most, according to the study.
The “data suggests that people who continued working during this early phase of the pandemic were less depressed than people who were not working, even though they were at greater risk of contracting the virus,” the researchers said.
Those who “remained employed as” essential “workers may have given new meaning to the respondents’ work, reducing the risk of depression.”
The researchers said that another factor in pandemic-related stress is the frequency with which participants were exposed to conflicting information from the news and social media.
People were immersed in the news for an average of seven hours a day, they found, and acute stress increased over time.
But consistent, accurate and reliable news reports may be one of the best ways to control stress, the researchers suggested.
