Hantavirus: US has no cases of Andes hantavirus – ABC7 Los Angeles

The United States currently has no confirmed cases of the Andes hantavirus, according to reporting from ABC7 Los Angeles. This confirmation comes amid an ongoing public health situation involving potential exposures on a cruise ship and a separate contagion investigation in South America.

In Argentina, health officials are working to identify the origin of a hantavirus contagion, as reported by The New York Times. The effort to trace the source of the outbreak is a priority for authorities in the region.

The potential for transmission has led to the monitoring of individuals in the United States who may have been exposed while traveling. WOWT reports that two additional people exposed to the hantavirus on a ship have arrived at a quarantine unit at UNMC-Nebraska Medicine.

Despite the quarantine measures for some individuals, the Centers for Disease Control and Prevention (CDC) is not requiring all cruise passengers who were exposed to the virus to isolate at home, according to BorderReport.

The process of confirming infections has encountered some diagnostic challenges. An American doctor who initially received a positive test result for the virus later stated that further testing showed no evidence that I’ve had hantavirus, according to ABC News.

Public Health Context of Andes Hantavirus

Hantaviruses are a family of viruses typically spread to humans through contact with infected rodents, particularly through the inhalation of aerosolized urine, droppings, or saliva. Most hantavirus strains are not known to transmit between humans.

The Andes strain is a significant concern for public health officials because it is the only known hantavirus capable of person-to-person transmission. This unique characteristic is why exposures in enclosed environments, such as cruise ships, trigger rigorous monitoring and quarantine protocols to prevent further spread.

When the virus affects humans, it can lead to Hantavirus Pulmonary Syndrome (HPS), a severe respiratory disease. Because the early symptoms of HPS can resemble the flu, accurate and repeated testing is essential for a confirmed diagnosis, as seen in the case of the American doctor whose initial positive result was later overturned.
