On May 2, 2026, a cruise ship in the Atlantic Ocean reported the outbreak of Andes virus, a type of Hantavirus that already existed in the Americas and Europe. Casualties, symptoms, and the spread of the virus renewed global attention surrounding it while bringing back the memories of the initial outbreak of COVID-19.
Since then, it has been linked to how COVID-19 is transmitted between humans, leading to the spread of the pandemic. However, evidence suggests human-to-human transmission is different in both cases; the SARS-CoV-2 virus was transmitted to an average of two or more people within populations that had not previously been exposed. As for the Andes virus, the transmission on the ship happened under very specific conditions of human-to human interaction: the presence of symptomatic individuals in crowded, poorly ventilated spaces with direct and continuous contact. Some experts from the World Health Organisation (WHO) note that the current Hantavirus outbreak on the cruise ship doesn’t qualify as the next “COVID-19” pandemic. Although it signals risks for affected people, it replicates slowly, spreads mainly through close contact, and appears to be most effective when symptoms appear. Nevertheless, other experts warn about the implications of the outbreak of the virus, citing its fatal symptoms and its shift in its traditional method of transmission. This raises a crucial question about whether Hantavirus can realistically become a pandemic.
This paper examines the potential for Hantavirus to evolve into a global pandemic threat by assessing its biological characteristics, transmission patterns, mortality rates, as well as its current global situation, including geographic distribution. It also assesses whether Hantavirus meets the established criteria for a pandemic, including sustained human-to human transmission, international spread potential, asymptomatic transmission, urban transmission, and containment challenges. In addition, the paper explores potential future trajectories for Hantavirus outbreaks by analysing scenarios ranging from continued local outbreaks to expanded regional transmission, as well as the low-probability but potentially high-impact pandemic driven by mutations. The report also addresses policy implications, early warning indicators, and lessons learned from the COVID-19 pandemic to assess gaps in preparedness and response capacity.
Methodologically, this paper adopts both qualitative and quantitative approaches that rely primarily on primary data/numbers and secondary sources. It draws on reports and data from international health organizations, such as the WHO, statistical facts, along with peer-reviewed academic literature, epidemiological studies, and expert analyses. The study also employs a comparative analysis of Hantavirus and COVID-19 to identify similarities and differences in defined indicators, such as transmissibility, mortality rates, and pandemic capability. Furthermore, the paper utilises scenario-building and risk
assessment methods to evaluate potential future outbreak trajectories and preparednessindicators as well as challenges.
