The recent hantavirus outbreak on a Dutch-flagged cruise ship has unexpectedly thrown us back into the swirling currents of conspiracy theories that defined the COVID-19 pandemic. It’s a surreal feeling, like a bad dream we thought we’d woken up from, only to find ourselves right back in it. Suddenly, the familiar whispers of global plots, forced vaccinations, and secret agendas are echoing across the internet, mimicking the unsettling chorus that often drowned out clear, factual information during the darkest days of the coronavirus crisis. Even as the World Health Organization reassures everyone that the risk to the general public from the cruise ship passengers is minimal, these old narratives are refusing to stay buried.
It’s almost chilling how quickly the rhetoric reappeared. Figures like Alex Jones, a name synonymous with conspiracy theories, wasted no time in declaring this hantavirus incident as “Covid 2.0,” a deliberate “LOCKDOWN ALERT” launched by “Globalists.” His words, shared on platforms like X, painted a picture of a switch being flicked, instantly reactivating the same anxieties and suspicions. This message then cascaded through online communities, with countless posts labelling the outbreak a “plandemic” – a term resurrected from a widely discredited pseudo-documentary from 2020 that propagated numerous falsehoods about COVID-19. The human element here is the sheer speed and ease with which these narratives can resurface, tapping into a collective memory of fear and distrust, almost bypassing logical thought. We’re witnessing how a relatively contained health incident can be instantly recast as a global conspiracy, demonstrating the potent and persistent nature of misinformation.
What’s particularly striking about this resurgence is the way the narrative has been molded to fit various pre-existing beliefs and anxieties. An AFP analysis revealed a pervasive undercurrent of claims alleging a sinister plot to coerce vaccinations, enforce lockdowns, or even manipulate the upcoming US elections by justifying expanded mail-in ballots. This last point is especially poignant, as it directly connects health anxieties to political ones, aligning with the baseless claims of election deniers. Yotam Ophir, who leads the Media Effects, Misinformation and Extremism lab at the University at Buffalo, highlights this concerning trend. He explains that during the COVID-19 pandemic, health misinformation became deeply intertwined with political identity, meaning that narratives about election rigging or political manipulation can easily “prime existing beliefs.” It’s as if the pandemic created a fertile ground where these different anxieties could cross-pollinate, leading to complex, multi-layered conspiracy theories that feel more personal and politically charged than ever before. This merging of health and politics creates a particularly potent and dangerous cocktail of misinformation.
Beyond the political angles, the resurfacing theories also echo the themes of greed and control that dominated the COVID-19 era. Some posts, for example, cherry-picked past articles about potential hantavirus vaccines, combined them with older comments from figures like Bill Gates, and even referenced a fictional 1990s TV show, all to “prove” that the hantavirus was intentionally released. The alleged motives? To reduce the global population or to line the pockets of pharmaceutical companies. Even more bizarrely, some individuals claimed the hantavirus was a side effect of Pfizer’s COVID-19 vaccines. This claim twisted a legitimate document that merely listed hantavirus among many “adverse events of special interest” – events that were being monitored, not caused by the vaccine. Ophir points out that these conspiracy theories are not new; they have a long, historical lineage, tracing back to centuries-old fears of diseases being manufactured by elites. However, what has dramatically changed is the speed at which they spread, fueled by social media algorithms that act like accelerants, and sometimes, worryingly, amplified by anti-vaccine voices who have found their way into influential positions. It’s a reminder that while the core fears might be ancient, the tools of their dissemination are frighteningly modern and efficient.
And just like during the height of COVID-19, where there’s a virus, there are instantly “miracle cures” peddled by dubious sources. Hantavirus, for which there are currently no approved vaccines or known cures, and which is typically spread by infected rodents, quickly became a target for these unproven remedies. Online, certain anti-establishment physicians and even some politicians immediately began touting the anti-parasitic drug ivermectin and other medications as effective treatments. We saw this play out with former US representative Marjorie Taylor Greene, who not only called the virus a “bioweapon” designed to make pharmaceutical companies profit from “poison” vaccines, but also amplified claims about ivermectin from Texas otolaryngologist Mary Talley Bowden, a figure previously fact-checked for spreading misinformation. Bowden even went so far as to offer to sell ivermectin, while Florida Governor Ron DeSantis renewed efforts to support legislation making ivermectin available without a prescription. This reckless promotion infuriates experts like John Lednicky, a virologist at the University of Florida, who emphatically states, “There is extreme misinformation about ivermectin. Outside of laboratory tests, ivermectin has not proven effective in treating infections.” This human tendency to grasp at quick fixes, often fueled by distrust in conventional medicine, is a recurring and dangerous pattern.
Ophir wisely suggests that the promotion of these COVID-era conspiracy theories might serve multiple purposes – from currying political favor to being financially motivated. In moments of anxiety and confusion, he notes, “online influencers, social media groups, or AI-operated users, may seize the chance to make some money.” This perfectly encapsulates the human element of opportunism in the face of uncertainty. The revival of these conspiracy theories following a relatively contained hantavirus outbreak is a stark reminder that the battle against misinformation is far from over. It highlights how deeply ingrained these narratives have become, how easily they can be reactivated, and the persistent challenge of distinguishing fact from fiction in an increasingly noisy and polarized digital world. Ultimately, it’s a lament for the vulnerability of truth in the face of fear, distrust, and calculated manipulation, and a call for continued vigilance in seeking out reliable information and critically evaluating what we encounter online.
