Three people died following a hantavirus outbreak of the Andes strain on a cruise ship earlier this month [4].

Health officials are monitoring the situation to ensure the virus does not spread further within the U.S. population. Because the virus requires very close contact to transmit, experts believe the risk of a wide-scale epidemic is low.

Eighteen passengers were repatriated to the U.S. for medical monitoring [1]. Of those individuals, 16 are being monitored in Nebraska, and two were transferred to Emory University in Atlanta [2, 3].

Nebraska health officials said all 16 people in their state are asymptomatic [6]. In Atlanta, one of the two patients is experiencing symptoms [7]. Despite these cases, officials said the virus does not spread easily [6].

A spokesperson for the World Health Organization said, "This Is Not Covid, Nor Influenza. It Spreads Very Differently" [3]. The organization noted that the transmission mechanism differs significantly from respiratory viruses that caused previous global pandemics.

U.S. health officials said the incident will not turn into an epidemic because hantaviruses do not spread easily [4]. The monitoring process in Nebraska and Georgia remains ongoing to track any potential delayed onset of symptoms among the repatriated group.

“"This Is Not Covid, Nor Influenza. It Spreads Very Differently"”

The rapid repatriation and monitoring of passengers demonstrate a heightened state of vigilance in public health surveillance following the COVID-19 pandemic. By isolating the Andes strain—which is rarer than other hantaviruses and capable of limited human-to-human transmission—authorities are attempting to prevent a localized cluster from becoming a broader public health crisis.
