Alaskapox virus

Alaskapox virus is a species of the Orthopoxvirus genus, first documented in 2015 in the United States state of Alaska.[1] As of 2022, there are four reported cases of illness caused by the virus, all of which occurred in Fairbanks North Star Borough, with none resulting in hospitalization or death.[2]

Discovery

In July 2015, a woman visited a clinic in Fairbanks, Alaska, with lesions that were confirmed to contain an Orthopox virus but did not match any known members of the genus.[1] Subsequent genetic analysis established that the woman, who recovered, had been infected with a novel Orthopox virus.[1] The name Alaskapox virus was proposed after full analysis of its genome was published in 2019.[3]

Subsequent cases

In 2020, the Alaska Department of Health and Social Services announced the second known infection of Alaskapox in another Fairbanks woman.[4] Two additional cases were identified in the Fairbanks area in the summer of 2021.[5] All four known cases were mild, not requiring hospitalization.[5]

All known cases have occurred in Fairbanks North Star Borough, but it is possible that other infections have occurred elsewhere.[2]

Signs and symptoms

In the identified cases, Alaskapox virus causes small lesions on the skin that heal after a few weeks, according to the Alaska Department of Health and Social Services,[2] but the first known patient indicated the lesion took six months to fully resolve.[1] Other reported symptoms include joint or muscle pain and swollen lymph nodes.[2]

Transmission

Transmission of the virus to humans is hypothesized to be via small animals,[5][6] though it is not yet clear specifically how this occurs.[2] As of 2021, there was not established evidence of transmission among humans.[5]
