A science journalist analyzes data showing that a virus’s transmission rate drops by 40% with each new mask technology. If the baseline transmission rate is 3.5, what is the rate after three successive improvements?

A Science Journalist Reveals How Mask Technology Slashes Virus Transmission Rates In recent years, the role of masks in controlling airborne virus transmission has come under intense scientific scrutiny—and one striking revelation centers on how successive generations of mask technology dramatically reduce transmission risk. Drawing on real-world data, a leading science journalist analyzed transmission rates and confirmed a powerful trend: with each new advancement in mask design, the virus’s ability to spread drops by approximately 40%. ### From Baseline to Breakthrough: The Science Behind Improved Masks If the baseline transmission rate of a virus is 3.5 (meaning one infected person infects 3.5 others on average), then each generation of mask innovation cuts this rate by 40%. That means the transmission rate is multiplied by 60%—or 0.6—with every technological leap.
