An elderly man has died from Alaskapox, the first known fatality from the recently discovered virus, Alaskan state health officials have said.
The man, who lived in the remote Kenai Peninsula, was hospitalised in November last year and died in late January, according to a bulletin issued last week by public health officials.
The man was undergoing cancer treatment and had a suppressed immune system because of the drugs, which may have contributed to the severity of his illness, the bulletin said. It described him as elderly but didn’t provide his age.
Alaskapox, also known as AKPV, is related to smallpox, cowpox and mpox, health officials said. Symptoms can include a rash, swollen lymph nodes and joint or muscle pain.
Only six other cases of the virus have been reported to Alaska health officials since the first one in 2015. All involved people were living in the Fairbanks area, more than 483km (300 miles) from the Kenai Peninsula, health officials said.
All had mild cases and recovered without being hospitalised.
The man who died “resided alone in a forested area and reported no recent travel and no close contacts with recent travel, illness, or similar lesions,” the health bulletin said.
It’s unclear how AKPV is transmitted but researchers say it may be zoonotic, meaning it can jump from animals to humans. The bulletin said that tests found evidence of current or previous infection in several species of small mammals in the Fairbanks area, including red-backed voles, and at least one domestic pet.
The man said he had cared for a stray cat at his home, the bulletin said.
The cat tested negative for the virus but it “regularly hunted small mammals and frequently scratched the patient”, the bulletin said.
That opens the possibility that the cat had the virus on its claws when it scratched him. The bulletin said a “notable” scratch near the armpit area where the first symptom – a red lesion – was seen.
Health officials said there hadn’t been any documented cases of humans passing on the virus but they recommended people with skin lesions possibly caused by Alaskapox to cover the affected area with a bandage.
Other suggestions included thoroughly washing hands, avoiding sharing clothing that might have touched the lesions and to launder clothing and sheets separately from other household items.
Health authorities also urged Alaskans to follow federal health precautions when around wildlife to avoid potential Alaskapox infections.
