Auger, K.A., Shah, S.S., et al. 2020. “Association Between Statewide School Closure and COVID-19 Incidence and Mortality in the US.” JAMA. 2020;324(9):859–870.

Question  Was statewide school closure associated with decreased incidence and mortality for coronavirus disease 2019 (COVID-19)? Findings  In this US population–based time series analysis conducted between March 9, 2020, and May 7, 2020, school closure was associated with a significant decline in both incidence of COVID-19 (adjusted relative change per week, −62%) and mortality (adjusted relative change […]

COVID-19 cases could be related to the gender of a country’s leader. The findings show that COVID outcomes are systematically better in countries led by women. Female leaders were found to be locking their countries down far sooner than their male counterparts. https://www.weforum.org/agenda/2020/07/women-leaders-policymakers-covid19-coronavirus/

Key Messages from the Evidence Summary: • There is a paucity of evidence describing clusters or outbreaks of SARS-CoV-2 infection in condos, apartments and hotels. Available studies and media reports are summarized below. • Epidemiological investigations of multi-residential building and hotel outbreaks in the primary literature and reports in the media suggest droplet and contact […]

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

Erath, Byron, Andrea Ferro and Goodarz Ahmadi. 2020. “Aerosols are a bigger coronavirus threat than WHO guidelines suggest – here’s what you need to know.” The Conversation, July 9, 2020.

When someone coughs, talks or even breathes, they send tiny respiratory droplets into the surrounding air. The smallest of these droplets can float for hours, and there is strong evidence that they can carry live coronavirus if the person is infected. Until mid-July, however, the risk from these aerosols wasn’t incorporated into the World Health […]

ARTICLE: 239 Scientists: “It Is Time to Address Airborne Transmission of Coronavirus Disease 2019 (COVID-19)”

Lidia Morawska, Donald K Milton Clinical Infectious Diseases, Volume 71, Issue 9, 1 November 2020, Pages 2311–2313, https://doi.org/10.1093/cid/ciaa939 https://academic.oup.com/cid/article/71/9/2311/5867798 We appeal to the medical community and to the relevant national and international bodies to recognize the potential for airborne spread of coronavirus disease 2019 (COVID-19). There is significant potential for inhalation exposure to viruses in microscopic respiratory […]

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 […]
