An open letter to Dr Tedros Adhanom Ghebreyesus, Director General, WHO; Duncan Selbie, Chief Executive of Public Health England and Dr Robert Redfield, Director of CDC, from concerned doctors and scientists.
Dear Dr Ghebreyesus, Mr Selbie and Dr Redfield,
We are writing to you to ask that you urgently review and update your guidance on the transmission of SARS-CoV-2.
We know a great deal more about SARS-CoV-2 than we did at the beginning of the outbreak, and there is now very convincing evidence from world experts in a number of relevant fields, that this virus spreads by aerosolised droplet nuclei as well as by large droplets and contact spread. Current countermeasures, i.e. social distancing, facemasks, surface cleaning, and handwashing are not able to stop outbreaks in enclosed indoor environments, which can only be satisfactorily explained by airborne spread over distances greater than 2 metres. We would point out that the European Centre for Disease Control does include aerosol spread in its guidance.
The pandemic is accelerating: over 10 million known cases and half a million deaths to date. If we do not give the general public, employers, trade unions, governments and civil society consistent and dependable advice on all of the ways the virus spreads, including by aerosols indoors, we will face many more deaths and will not defeat this virus.
Millions look to you for guidance during this time, fearing illness and death for themselves and their loved ones. We owe it to them to provide accurate, reliable and up to date information about the virus so they are in the best position to protect themselves from it.
