Hantavirus cluster linked to cruise ship highlights ongoing zoonotic risk and the need for vigilance

"This incident is not indicative of a widespread travel risk, but it is a clear example of how zoonotic viruses that come from wildlife exposure can surface in confined or connected settings," said Scott C. Weaver, PhD, director of the Institute for Human Infections & Immunity at UTMB. "Hantavirus is primarily an environmental infection, and even in rare cases of human-to-human spread, it does not behave like highly transmissible respiratory viruses. The priority is vigilance, early identification, and clear, evidence-based communication.”
