Borealpox virus (BRPV)^[1] (formerly Alaskapox virus; AKPV)^[2] is a species of the Orthopoxvirus genus first documented in 2015 in Alaska, United States.^[3] As of February 2024, there are seven reported cases of illness, one of which became fatal due to a weakened immune system. The first six cases occurred in Fairbanks North Star Borough and the first fatality occurred in Kenai Peninsula Borough.^[4]^[5]^[6]

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. Subsequent genetic analysis established that the woman, who recovered, had been infected with a novel Orthopox virus.^[3] The name Alaskapox virus was proposed after a full analysis of its genome was published in 2019.^[7] The name Alaskapox virus was changed to borealpox virus on March 27, 2024.

Subsequent cases

In 2020, the Alaska Department of Health and Social Services (ADHSS) announced the second known infection of AKPV in another Fairbanks woman.^[8] Two additional cases were identified in the Fairbanks area in the summer of 2021,^[9] and by February 2024, seven cases total had been reported to the Alaska Section of Epidemiology.^[10] Until December 2023, all known cases had been mild, not requiring hospitalization.^[9]^[10]

In late January 2024, a Kenai man with an immunocompromising condition diagnosed with AKPV died, becoming the first death and first reported case outside of the Fairbanks North Star Borough.^[6] The patient had stated that a stray cat had scratched him near the site the lesion appeared and that he sought medical attention due to a tender red bump in his armpit in September 2023. Despite some sources claiming that the man died directly as a result of AKPV,^[11]^[2] his death has instead been attributed to kidney failure,^[12] although it has been said that there may have been some connection between his immunocompromised status and the lesion on his arm that resulted in his death.^[13]

Signs and symptoms

In the identified cases, AKPV causes small lesions on the skin that heal after a few weeks, according to the ADHSS,^[4] but the first known patient indicated the lesion took six months to fully resolve.^[3] Other reported symptoms include joint or muscle pain and swollen lymph nodes.^[4]

Transmission

Transmission of the virus to humans is hypothesized to be via small animals,^[9]^[14] though it is not yet clear specifically how this occurs.^[4] As of 2021, there was not established evidence of transmission among humans.^[9]

<span class="mw-page-title-main">Mpox</span> Viral disease of humans and animals

Mpox is an infectious viral disease that can occur in humans and other animals. Symptoms include a rash that forms blisters and then crusts over, fever, and swollen lymph nodes. The illness is usually mild, and most of infected individuals recover within a few weeks without treatment. The time from exposure to the onset of symptoms ranges from five to twenty-one days, and symptoms typically last from two to four weeks. However, cases may be severe, especially in children, pregnant women, or people with suppressed immune systems.

Hairy leukoplakia is a white patch on the side of the tongue with a corrugated or hairy appearance. It is caused by Epstein-Barr virus (EBV) and occurs usually in persons who are immunocompromised, especially those with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). The white lesion, which cannot be scraped off, is benign and does not require any treatment, although its appearance may have diagnostic and prognostic implications for the underlying condition.

Orthopoxvirus is a genus of viruses in the family Poxviridae and subfamily Chordopoxvirinae. Vertebrates, including mammals and humans, and arthropods serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include smallpox, cowpox, horsepox, camelpox, and mpox. The most widely known member of the genus is Variola virus, which causes smallpox. It was eradicated globally by 1977, through the use of Vaccinia virus as a vaccine. The most recently described species is the Alaskapox virus, first isolated in 2015.

Camelpox is a disease of camels caused by the camelpox virus (CMPV) of the family Poxviridae, subfamily Chordopoxvirinae, and the genus Orthopoxvirus. It causes skin lesions and a generalized infection. Approximately 25% of young camels that become infected will die from the disease, while infection in older camels is generally more mild. Although rare, the infection may spread to the hands of those that work closely with camels.

Rabbitpox is a disease of rabbits caused by a virus of the genus Orthopoxvirus in the family Poxviridae, and closely related to vaccinia virus. Rabbitpox was first isolated at the Rockefeller Institute in New York in 1933, following a series of epidemics in the laboratory rabbits. It is an acute disease only known to infect laboratory rabbits as no cases have been reported in wild rabbits; it cannot infect humans.

Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About 500 miles (800 km) of Canadian territory consisting of British Columbia separate Alaska from Washington U.S. state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S.

Smallpox was an infectious disease caused by variola virus, which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date.

<span class="mw-page-title-main">Herpes meningitis</span> Medical condition

Herpes meningitis is inflammation of the meninges, the protective tissues surrounding the spinal cord and brain, due to infection from viruses of the Herpesviridae family - the most common amongst adults is HSV-2. Symptoms are self-limiting over 2 weeks with severe headache, nausea, vomiting, neck-stiffness, and photophobia. Herpes meningitis can cause Mollaret's meningitis, a form of recurrent meningitis. Lumbar puncture with cerebrospinal fluid results demonstrating aseptic meningitis pattern is necessary for diagnosis and polymerase chain reaction is used to detect viral presence. Although symptoms are self-limiting, treatment with antiviral medication may be recommended to prevent progression to Herpes Meningoencephalitis.

Chordopoxvirinae is a subfamily of viruses in the family Poxviridae. Vertebrates and arthropods serve as natural hosts. Currently, 52 species are placed in this subfamily, divided among 18 genera. Diseases associated with this subfamily include smallpox.

The monkeypox virus is a species of double-stranded DNA virus that causes mpox disease in humans and other mammals. It is a zoonotic virus belonging to the orthopoxvirus genus, making it closely related to the variola, cowpox, and vaccinia viruses. MPV is oval, with a lipoprotein outer membrane. The genome is approximately 190 kb. Smallpox and monkeypox viruses are both orthopoxviruses, and the smallpox vaccine is effective against mpox if given within 3–5 years before the disease is contracted. Symptoms of mpox in humans include a rash that forms blisters and then crusts over, fever, and swollen lymph nodes. The virus is transmissible between animals and humans by direct contact to the lesions or bodily fluids. The virus was given the name monkeypox virus after being isolated from monkeys, but most of the carriers of this virus are smaller mammals.

Since 2012, an outbreak of Middle East respiratory syndrome coronavirus has affected several countries, primarily in its namesake, the Middle East. The virus, which causes Middle East respiratory syndrome (MERS), is a novel coronavirus that was first identified in a patient from Jeddah, Saudi Arabia on 6 June 2012.

H5N6 is a subtype of the species Influenza A virus. Infected birds shed the virus in their saliva, mucous, and feces. The virus was first detected in poultry in 2013, since then spreading among wild bird populations and poultry around the world. Humans can be infected through unprotected contact with infected birds or contaminated surfaces. The virus transmits by getting into a person's eyes, nose, mouth, and through inhalation. Human infections are rare. Since 2014, at least 87 cases have occurred in humans. 29 people have died. A spike in human cases was reported in 2021. There have been no confirmed cases of human-to-human transmission. Some infections have been identified where no direct contact with infected birds or contaminated surfaces has been known to had occurred. Only one infected woman has said that she never came into any contact with poultry.
