“Aerial viruses, including COVID-19, are highly contagious and easily spread,” the site now says.
Previously, the CDC page Govit-19 was mainly thought to spread about 6 feet between those in close contact – and “by respiratory droplets formed when the victim coughs, sneezes or speaks.”
These particles can cause infection “when inhaled into the nose, mouth, airways and lungs”. “This is considered to be the main way the virus spreads.”
“There is evidence that water droplets and airborne particles can be suspended in the air and inhaled by others, and travel distances beyond 6 feet (e.g. during singer training, in restaurants or fitness classes),” says Page now. “In general, indoor environments without good ventilation increase this risk.”
CDC has also added new measures to protect you and others.
Previously, the CDC recommended maintaining a “good social distance” of about 6 feet, washing hands, regularly cleaning and disinfecting surfaces, and covering your mouth and nose with a mask while others are around.
Now, it says “stay at least 6 feet away from others as much as possible” and continues to guide people to wear a mask and regularly clean and disinfect. However, it now says that people should stay indoors and be isolated when they are sick and “use air purifiers to help reduce germs in the air indoors.”
It states that masks and other preventive measures should not be changed.
The update also changed the language around asymptomatic transmission, from saying “some without symptoms can spread the virus” to “those who are infected but not showing symptoms can spread the virus to others.”
Scientists have volunteered to acknowledge aerial transmission
For months, scientists have been speculating about the possibility of the corona virus spreading through virus particles in the air, and have pushed health organizations to admit it.
In April, a valuable scientific team wrote in a letter to the White House that research shows that the corona virus can be spread not only through sneezing or coughing, but also through speech or breathing.
“At the present time [coronavirus] Specific research is scarce, and the results of available studies are consistent with the aerosolization of the virus from normal respiration, “said Dr. Harvey Feinberg, former dean of the Harvard School of Public Health and chairman of the NAS ‘Standing Committee on Emerging Infectious Diseases and 21st Century Health Threats.
“Currently available research supports that possibility [coronavirus] It can spread through bio-aerosols generated directly by patients’ breathing, ”the letter said.
“Current guidance from many international and national organizations focuses on hand washing, maintaining social distance and water droplet precautions,” the scientists wrote in a letter published in the journal Medical Infectious Diseases.
“Most public health organizations, including the World Health Organization, do not recognize airborne contamination, except for aerosol formulation procedures performed on health systems. Handwashing and social disassembly are appropriate, but in our view, micro droplets released into the air by infected people are not sufficient to provide protection from infectious respiratory infections,” they said. Added.
On Sunday, Donald Milton, an environmental health professor at the University of Maryland, who was one of the primary authors of the letter, examined how viruses spread, saying the CDC’s new language was a “big improvement.”
“I’m very excited to see CDC focus and move with science. Evidence is accumulating,” Milton wrote in an email to CNN.
“It’s time for the WHO to acknowledge these advances in science,” Milton said.
