Alaskapox virus in Child
Only 4 cases of Alaskapox have been reported (in both adults and children): 1 in 2015, 1 in 2020, and 2 in 2021. All cases occurred during mid-to-late summer in forested areas near Fairbanks, Alaska. Each case was self-limited. All cases began with the appearance of a small superficial skin ulcer. Associated symptoms and signs included surrounding erythema, induration, pain, lymphangitis, and painful adenopathy. Additional symptoms included fatigue, malaise, and subjective fever.
Serologic and viral polymerase chain reaction (PCR) testing of trapped animals from Interior Alaska has revealed past and current infection in various species of small mammals, including the northern red-backed vole, shrews, and squirrels.
There is currently no evidence of human-to-human transmission.
