Project Clean Access is about providing scientifically backed solutions to help create a safer environment. This literature review focused on gathering evidence of the different modes of transmission, as well as data on how successful various intervention measures have been.
The following video summarises the key findings from the literature review:
For those who cannot see the video, the key findings and associated sources are repeated here:
- The primary methods of transmission are thought to be aerosol, droplet, and fomites [WHO 2020]
- 20% of transmission is thought to be from asymptomatic people and up to 40% is from presymptomatic people [WHO 2020]
- Social distancing (worldwide average) has reduced cases by 13% [Islam 2020]
- 1-2 m likely not ‘safe’ in most scenarios, sneezes can travel as far as 8 metres (https://edhub.ama-assn.org/jn-learning/video-player/18357411) [Bourouiba 2020]
