Scientists urge WHO to review indoor air quality in wake of Covid-19
Professor Dr Akiko Iwasaki PhD, The Waldemar Von Zedtwitz Professor of immunobiology and professor of molecular, cellular and developmental biology at Yale, and an investigator for the Howard Hughes Medical Institute said: “90% of our lives in the developed world are spent indoors in close proximity to each other.
“When cold outdoor air with little moisture is heated indoors, the air’s relative humidity drops to about 20%. This dry air provides a clear pathway for airborne viruses, such as Covid-19.
“That’s why I recommend humidifiers during the winter, and why I feel the world would be a healthier place if all our public buildings kept their indoor air at 40 to 60% RH.”
