Yes, it's highly probable that a significant portion of the modern population could survive the Black Death, though it would be a devastating and deadly event.
While the Black Death, caused by the bacterium Yersinia pestis, was incredibly lethal in the 14th century, several factors contribute to increased survivability today:
-
Modern Medicine: Antibiotics are highly effective against Yersinia pestis. Early diagnosis and treatment dramatically increase survival rates. Were an outbreak to occur today, antibiotic stockpiles and rapid production capabilities would be deployed.
-
Public Health Infrastructure: We possess sophisticated public health systems for disease surveillance, quarantine, and sanitation. These measures could help contain the spread and reduce the number of infections.
-
Genetic Resistance: As highlighted in the reference material, some individuals possess genetic mutations that offer protection against the plague. For example, a mutation in the ERAP2 gene provided a 40% survival advantage during the Black Death. While not everyone carries this mutation, its presence in the modern population would contribute to overall survival.
-
Improved Living Conditions: Compared to the 14th century, we generally have better nutrition, hygiene, and sanitation. These factors bolster the immune system and reduce susceptibility to infectious diseases.
However, it's crucial to acknowledge that a re-emergence of the Black Death would still pose a serious threat:
-
Potential for Antibiotic Resistance: Overuse of antibiotics can lead to the development of antibiotic-resistant strains of Yersinia pestis, which would complicate treatment.
-
Rapid Spread: In a highly interconnected world, the plague could spread rapidly through international travel, overwhelming healthcare systems.
-
Resource Strain: A large-scale outbreak could strain healthcare resources, limiting access to treatment and potentially increasing mortality rates, particularly in regions with weaker healthcare infrastructure.
In conclusion: While not everyone would survive, our modern medical advancements, public health infrastructure, and pre-existing genetic resistance would significantly increase the likelihood of survival compared to the 14th century. However, the potential for antibiotic resistance and rapid spread necessitates constant vigilance and preparedness.
