Supported by leading members of the global scientificand medical community, the petition is designed to not only increase global awareness among the public on the crucial role indoor environmental quality plays in physical health, but also to call emphatically on the WHO to drive meaningful policy change; a critical necessity during and after the COVID-19 crisis.

One of the leading forces in the charge for a globally recognised 40-60%RH guideline for public buildings, Dr Stephanie Taylor,  MD, Infection Control Consultant at Harvard Medical School, ASHRAE Distinguished Lecturer & Member of the ASHRAE Epidemic Task Group commented: “In light of the COVID-19 crisis, it is now more important than ever to listen to the evidence that shows optimum humidity can improve our indoor air quality and respiratory health.

'It is time for regulators to place management of the built environment at the very center of disease control. Introducing WHO guidelines on minimum lower limits of relative humidity for public buildings has the potential to set a new standard for indoor air and improve the lives and health of millions of people.”

The group of scientists urges the public to read and sign the petition, which can be found here: http://40to60rh.com/
