  Recent outbreaks of hantavirus-a very lethal and zoonotic virus – An update and counteracting strategies - PMC↗

  pmc.ncbi.nlm.nih.gov · 2026-06-03

  A PMC article discusses recent hantavirus outbreaks, highlighting its lethality and zoonotic nature. It mentions that hantavirus surveillance in the US began in 1993 in the Four Corners region (Colorado, New Mexico, Arizona, Utah). The article also references 2022 cases in Brazil (22 cases, 10 deaths) and Panama (29 cases), emphasizing the global distribution and high mortality rates associated with the virus, particularly in South America.

  Experts note that hantavirus causes relatively small numbers of cases annually in South American countries such as Argentina, Paraguay, Brazil, and Chile, but with a high case fatality rate typically between 20% and 40%, making it a public health concern. The infection can become evident in a patient between one to eight weeks after exposure. The current cruise ship outbreak most likely involves the Andes virus, which is a New World Hantavirus found in Argentina. The danger with New World Hantaviruses is their unspecific early presentation, resembling flu-like diseases, and their progression t

  The deadly hantavirus outbreak on the MV Hondius cruise ship, linked to the Andes strain, has drawn attention to how environmental disruption can increase disease risk. Published on May 8, 2026, this article suggests that deforestation, such as in the Brazilian Atlantic Forest, can contribute to outbreaks by affecting rodent populations. Scientists propose that forest restoration and increased biodiversity could help control reservoir rodent populations and mitigate hantavirus spread.
