#CoronavirusUpdate 2021/7/29🇯🇵 A physicist argues by using a brilliantly crafted animated scale to show how #StateofEmergency measures #緊急事態宣言 “cannot be used over and over again” because its effectiveness is limited without hard #lockdown measures.

Dr. @ryseto updated his infographic after 3,177 cases were confirmed in Tokyo on July 28, saying "SoE declaration which can have some effect by just 'declaring" cannot be used over and over again," suggesting the declarations have not been enough.
Earlier on, he also used his infographic to show how #VoC (Variant of Concern) has been replacing the original strain of #COVID19 in #Asia. It shows a more strong measure is needed or otherwise we will be crushed by the 'apparent shift' in the equation.
Dr. Seto explained that he specifically assumed the #DeltaVariant in his image and that the avg # of people infected by an infected person (R0) is determined by the infectivity of the virus and the restrictions that are in place and/or the level of self-restraint enforced.

Dr. Seto then explained that the ‘angle’ of the slope remains constant because it does not change depending on total # of infected people. However, “when a highly infectious variant strain spreads, the entire slope becomes steeper,” therefore requiring a more restrictive measure.
