How the word 'plague' strikes fear and panic – from 1920s LA to modern-day Siberia

**Lead**

Across centuries and continents, the word 'plague' has carried a unique, almost supernatural power to incite fear and chaos. From the frantic quarantine measures that gripped Los Angeles in the 1920s to the isolated yet alarming outbreaks that periodically surface in the vast expanses of Siberia, the term alone – regardless of the actual scale of the threat – often triggers a cascade of panic that complicates public health responses. This phenomenon, which lies at the intersection of epidemiology and mass psychology, remains a critical security concern for governments and health agencies worldwide.

**Context**

In the autumn of 1924, a small outbreak of pneumonic plague erupted in the heart of Los Angeles. The disease, transmitted through respiratory droplets, was a terrifying prospect in an era before effective antibiotics. Although the actual number of cases was limited – by some historical accounts fewer than 40 people were infected – the response was anything but measured. Local authorities imposed a strict quarantine on the affected neighbourhood, which was largely inhabited by Mexican-American residents. The area was cordoned off, with armed guards preventing anyone from leaving. News reports at the time described scenes of near-hysteria among the population, and the event became a flashpoint for racial tensions. The word 'plague' had transformed a contained health incident into a city-wide crisis, with lasting social and political repercussions.

Fast-forward nearly a century to the vast, sparsely populated region of Siberia. In recent decades, the thawing of permafrost due to climate change has raised the terrifying prospect of ancient pathogens being released. In 2016, an outbreak of anthrax – a disease often conflated with plague in the public imagination – occurred in the Yamal Peninsula, killing a child and hospitalising dozens. More specifically, cases of bubonic plague have been reported in the Altai Republic and other Siberian areas, linked to infected marmots and changing animal migration patterns. When such cases are reported in Western media, the headlines almost inevitably use the word 'plague', conjuring images of the Black Death and medieval devastation, even when the actual risk of a widespread epidemic is exceedingly low.

**Analysis**

The disproportionate fear associated with the word 'plague' is not merely a historical curiosity; it has profound implications for modern security. Public health authorities must now contend with a phenomenon known as 'epidemic of fear', where the anxiety surrounding a disease can overwhelm the capacity to respond effectively. In Los Angeles in the 1920s, the panic led to discriminatory policies and a breakdown of trust between the community and authorities. In Siberia today, the mere rumour of a plague case can disrupt local economies, particularly in tourism and agriculture, and strain already limited health infrastructure.

From a security perspective, the word 'plague' also carries a strategic dimension. Bioterrorism experts have long warned that the psychological impact of a deliberately released plague pathogen would far exceed its physical toll. The name itself is a weapon. Governments invest substantial resources in biosecurity measures, but the success of any response depends as much on managing public perception as on medical countermeasures. The modern-day outbreaks in Siberia underscore the need for robust surveillance systems and clear, calm communication strategies to prevent the word 'plague' from becoming a catalyst for uncontrollable fear.

The historical account of the 1924–1925 Los Angeles pneumonic plague outbreak draws on published epidemiological records and contemporary newspaper archives from the Los Angeles Times and other periodicals. Modern Siberian plague and anthrax cases are documented by the World Health Organization (WHO) regional office and the Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor). Analysis of the psychological impact of disease terminology is informed by research published in journals such as The Lancet and the Journal of Public Health Policy.
