Ms. Arakawa, the wife of the actor Gene Hackman, died from the effects of a disease often caused by contact with droppings from infected rodents.

Betsy Arakawa died from hantavirus pulmonary syndrome, a rare rodent-spread disease with a mortality rate up to 50% in the American Southwest, officials said.

Betsy Arakawa — the classical pianist married to Gene Hackman — died last month of hantavirus pulmonary syndrome, a rare infectious disease linked to rodents, New Mexico authorities announced Friday.

Gene Hackman died of cardiovascular disease about a week after his wife died of hantavirus, according to the New Mexico medical examiner.

The partially mummified bodies of Hackman and his wife, Betsy Arakawa, were discovered in February at their home in New Mexico.

Investigation revealed that Betsy Arakawa, a pianist and wife of actor Gene Hackman, had died from hantavirus pulmonary syndrome, a rare infectious disease.

There are at least 38 recognized species of hantavirus across the world, 24 of which cause disease in humans. It’s considered a rare virus but it’s also likely to be underdiagnosed in many areas of the world because the initial symptoms can be mistaken for cold and flu-like viral infections.

Betsy Arakawa died of hantavirus pulmonary syndrome at the age of 65, New Mexico health authorities said. Here’s what to know about the rare but deadly disease.
