Top scientists from leading research institutions publish letter in the journal Science citing “overwhelming evidence” that airborne transmission is a “major route” for SARS-CoV-2, urging scientific community to clarify the terminology used related to aerosols

Scientists affiliated with leading research institutions across the U.S. publish open letter in the journal Science that the scientific community must clarify the terminology used related to aerosols and droplets, and employ a more modern size threshold, rather than the existing one based on 1930s-era work. Authors include experts from the University of California San […]

Senator Tim Kaine questions Centers for Disease Control (CDC) Director Robert Redfield on the CDC removing guidance on its website pertaining to airborne spread of COVID-19.

WASHINGTON, D.C.— On September 24th, 2020, in a Senate Health, Education, Labor, and Pensions (HELP) Committee hearing titled “COVID-19: An Update on the Federal Response,” U.S. Senator Tim Kaine pressed Centers for Disease Control (CDC) Director Robert Redfield on the CDC removing guidance on its website pertaining to airborne spread of COVID-19. Kaine asked about […]

US Centers for Disease Control (CDC) updates web page to say airborne virus through aerosols is the PRIMARY path for transmission of COVID: ““This is thought to be the main way the virus spreads.”

CDC (temporarily) changes web page to say: Airborne viruses, including COVID-19, are among the most contagious and easily spread. Covid-19 most commonly spreads between people who are in close contact with one another, and now says the virus is known to spread “through respiratory droplets or small particles, such as those in aerosols, produced when […]

WHO releases report acknowledging coronavirus can pass from one person to another through the air, still denying it as major path of transmission.

WHO released a report in reply to the 239 scientists, that detailed how the coronavirus can pass from one person to another, including through the air during certain medical procedures and possibly the air in crowded indoor spaces. https://www.who.int/publications/i/item/modes-of-transmission-of-virus-causing-covid-19-implications-for-ipc-precaution-recommendations https://www.npr.org/sections/goatsandsoda/2020/07/09/889526937/who-report-aerosols-not-likely-to-be-significant-source-of-covid-19-transmission

239 scientists from 32 countries write in open letter that evidence suggests “beyond any reasonable doubt” that the virus spreads indoors through aerosols, urging the WHO to address this in their recommendations.

https://www.the-scientist.com/news-opinion/scientists-urge-consideration-of-airborne-sars-cov-2-transmission-67702 Mounting evidence suggests that tiny viral particles that linger in the air in indoor spaces are a significant source of coronavirus infection, according to 239 experts who wrote an open letter to the World Health Organization (WHO) urging the agency to issue appropriate warnings about the risks posed by the particles, known as aerosols. The letter was published […]

Expert panel tells White House coronavirus can spread through talking or even just breathing

Dr. Harvey Fineberg from US National Academy of Sciences reports that results of available studies are consistent with aerosolization of virus from normal breathing, in response to request concerning the possibility that SARS-CoV-2 could be spread by conversation, in addition to sneeze/cough-induced droplets. Currently available research supports the possibility that SARS-CoV-2 could be spread via […]
