Maurice de Hond herhaalt in zijn stuk van vandaag -‘Journalistiek in coronatijd is als Erica Terpstra bij de Dalai Lama‘- (20 september) de Lancet COVID-19 Commission Statement inzake aerosolen (small particles). Helaas ontbreekt een link naar de complete Lancet Commission Statement. Onderstaand de betreffende Lancet aerosolen bevindingen plus een link naar de volledige tekst.
15. Identifying the dominant modes of COVID-19 transmission is an urgent public health priority. There is growing consensus from the aerosol science and infectious disease communities that aerosol inhalation is a key contributor to COVID-19 transmission. The US Centers for Disease Control and Prevention (CDC) and WHO have widely communicated a narrowed scope of possible transmission routes, limited to large droplets expelled by coughs and sneezes, and contact with contaminated surfaces. However, this notion is based on an incorrect assumption that 5 μm particles settle out of the air within 2 m (6 ft). Basic aerosol physics shows that people shed an entire continuum of particles when they cough, sneeze, breathe, or talk. Some of these are very large particles that do settle out of the air quickly because of gravity (influencing the 2 m [6 ft] distancing rule), but the vast majority are smaller particles that stay aloft for between 30 min and several hours, and travel beyond 2 m (6 ft). Mitigating airborne transmission is especially crucial for reducing the risk of superspreader events. These events appear to occur mainly or exclusively indoors, although large outdoor events are often preceded or followed by indoor crowds at bars, pubs, and restaurants.

Lancet COVID-19 Commission Statement on the occasion of the 75th session of the UN General Assembly
Executive summary
The Lancet COVID-19 Commission was launched on July 9, 2020, to assist governments, civil society, and UN institutions in responding effectively to the COVID-19 pandemic. The Commission aims to offer practical solutions to the four main global challenges posed by the pandemic: suppressing the pandemic by means of pharmaceutical and non-pharmaceutical interventions; overcoming humanitarian emergencies, including poverty, hunger, and mental distress, caused by the pandemic; restructuring public and private finances in the wake of the pandemic; and rebuilding the world economy in an inclusive, resilient, and sustainable way that is aligned with the Sustainable Development Goals (SDGs) and the Paris Climate Agreement. Many creative solutions are already being implemented, and a key aim of the Commission is to accelerate their adoption worldwide.
The origins of COVID-19 and averting zoonotic pandemics
The COVID-19 pandemic is the latest—but certainly not the last—emerging infectious disease, preceded by HIV/AIDS, Nipah, severe acute respiratory syndrome coronavirus, H1N1 influenza, Middle East respiratory syndrome coronavirus, Zika, Ebola, and others. These diseases are zoonoses, resulting from pathogens being transmitted from animals to humans. To protect against zoonoses, we require new precautions, such as ending deforestation and protecting conservation areas and endangered species. The origins of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are yet to be definitively determined, but evidence to date supports the view that SARS-CoV-2 is a naturally occurring virus rather than the result of laboratory creation and release. Research into the origins of SARS-CoV-2 should proceed expeditiously, scientifically, and objectively, unhindered by geopolitical agendas and misinformation.

In de Lancet Commission Statement wordt (weer) gerept van ‘the 2 m [6 ft] distancing rule‘. Wat bevreemd-opvallend nog steeds een verre van algemeen aanvaarde rule is. De WHO blijft 1 meter voldoende vinden. Het RIVM blijft 1,5 meter voldoende vinden.
