The hantavirus has returned to the news after several cases were detected on a cruise traveling from Argentina to Canary Islands, reactivating health alerts about this rare but potentially deadly infection. Specifically, this virus was also linked to a high-profile case just a year ago, the death of Betsy Arakawa, wife of actor Gene Hackman.
Both were found dead in their residence in New Mexico under initially unclear circumstances, as the bodies were in separate rooms and there were no signs of forced entry. This led authorities to conduct a thorough investigation and autopsies to determine the causes of death.
Forensic results established that Betsy Arakawa died from a pulmonary syndrome caused by hantavirus, a disease that in its early stages can be mistaken for a common respiratory infection, such as the flu. The rapid progression to severe respiratory failure explains why the diagnosis may be delayed if the disease is not suspected.
Following the discovery, public health teams inspected the residence and found clear evidence of rodent presence: nests, droppings, and remains in different areas of the property. These elements are relevant because the virus is not typically transmitted directly between people, but through particles from infected rodents, especially when inhaled in enclosed or poorly ventilated spaces.
In the same incident, Gene Hackman's autopsy determined that his death was due to a severe heart disease, unrelated to hantavirus. However, the fact that both cases occurred in the same household drew significant media and health attention, given the rare but potentially lethal nature of the infection.
This episode contributed to bringing hantavirus back into the spotlight, reminding that it can go unnoticed for days or weeks due to its incubation period and nonspecific initial symptoms.
According to the World Health Organization, seven people on the cruise have been affected, with three fatalities, one patient in critical condition, and others with mild symptoms. On board the ship are about 150 people, including Spanish passengers, who currently do not show symptoms. Health authorities consider, as the main hypothesis, that the contagion may have occurred before boarding due to the virus's incubation period.
Hantavirus is a disease caused by different types of viruses associated with rodents. Transmission mainly occurs by inhaling contaminated particles from the urine, feces, or saliva of these animals, especially in enclosed or poorly ventilated spaces. It can also occur through direct contact or, less commonly, through bites. Person-to-person transmission is extremely rare.
