sandervdw zei:De Spaanse griep is gestopt omdat een mutatie minder dodelijk was dan de vorige versie. Niet door groepsimmuniteit.
De Pest is ook nooit door immuniteit gestopt. Er zijn niet minder zieken gekomen, er zijn gewoon minder doden gevallen omdat de zwakkeren allemaal al gestorven waren.
Die bron mag je me toch eens tonen dan. Want ik lees toch iets anders in the time.com:
“The end of the pandemic occurred because the virus circulated around the globe, infecting enough people that the world population no longer had enough susceptible people in order for the strain to become a pandemic once again,” says medical historian J. Alexander Navarro, Markel’s colleague and the Assistant Director of the Center for the History of Medicine. “When you get enough people who get immunity, the infection will slowly die out because it’s harder for the virus to find new susceptible hosts.”
Eventually, with “fewer susceptible people out and about and mingling,” Navarro says, there was nowhere for the virus to go —the “herd immunity” being talked about today. By the end of the pandemic, a whopping third of the world’s population had caught the virus. (At the moment, about half a percent of the global population is known to have been infected with the novel coronavirus.)
Dat klinkt als groepsimmuniteit via besmetting.
