Scientists Explain How Andes Virus Strain of Hantavirus Spreads From Person to Person

Recent misinformation circulating on social media suggests that hantavirus is not transmissible between humans, a claim that scientists have long refuted. Delfi's "Melo detektorius" (Lie Detector) feature aims to debunk this dangerous falsehood, emphasizing that a specific strain, the Andes virus, is indeed capable of human-to-human transmission.

Scientific consensus, supported by numerous studies over the past two decades, confirms that the Andes virus can spread through direct contact with infected bodily fluids, such as nasal secretions and saliva. Furthermore, research indicates a potential for airborne transmission, posing a significant public health concern. This is a critical distinction from other hantavirus strains, which are primarily transmitted through rodents.

Lie. Scientists have known for more than 20 years that the Andes virus is a strain of hantavirus that humans can infect humans with.

The article highlights a substantial outbreak in Argentina in 2018, which resulted in 11 fatalities and clearly illustrated the virus's capacity to spread within families and communities. Despite such evidence, the persistent spread of misinformation online necessitates a clear, science-based response to protect public health. Lithuania, like other nations, must remain vigilant against such viral threats and the disinformation that can exacerbate their impact.

From a Lithuanian perspective, understanding the nuances of viral transmission is paramount. While the Andes virus outbreak was centered in Argentina, the global nature of information flow means that such health risks, and the misinformation surrounding them, can reach any corner of the world. Delfi's role in providing accurate, science-backed information is crucial in combating public health threats and ensuring citizens are well-informed about potential dangers, regardless of their geographical origin.

This allows us to assume that the virus is transmitted through airborne droplets. This was also confirmed by another study published in 2024, which described that the virus was detected in the saliva, nasopharynx, and other bodily fluids of infected individuals.
