A genetically modified version of the Black Death could potentially wipe out life across the globe within hours, according to a scenario detailed by the Daily Mail. The hypothetical outbreak begins as an individual arrives in Los Angeles and travels downtown, with the disease spreading silently. By the following morning, the outbreak escalates, with people on the streets experiencing convulsions and collapsing.

The scenario emphasizes the rapid and devastating progression of such a bioengineered pathogen, illustrating a swift collapse of populations and societal order. The hour-by-hour breakdown suggests a disease designed for maximum transmissibility and lethality, leading to a rapid and near-total extinction event. The description highlights the speed at which the disease would manifest and spread, leading to immediate and widespread public health consequences.
