Mpox Outbreak in Anchorage: Alaska Health Officials Report Rise in Local Cases

Anchorage Health Officials Monitor Rising Mpox Cases

A string of four mpox cases in Anchorage has caught the attention of state health officials, marking the highest annual count for Alaska since the global outbreak of 2022. While the numbers remain small in absolute terms, the circumstances surrounding these infections represent a departure from previous patterns. Unlike the cases recorded in Alaska over the past several years, these four patients reported no travel outside the state within the 30-day window before their symptoms began.

The state Department of Health issued an alert last week to notify the public and healthcare providers as three of the cases surfaced in October. A fourth case was confirmed on Thursday, according to Dr. Joe McLaughlin, the Alaska state epidemiologist. This cluster follows a quiet period for the state; between 2023 and 2025, Alaska saw only two documented cases of the viral disease, which was formerly known as monkeypox.

The Shift in Transmission Patterns

The absence of travel history among the recent patients complicates the investigation into how the virus is moving through the community. Dr. Randi Rollins, an epidemiologist with the U.S. Centers for Disease Control working alongside the Alaska Department of Health, noted that this finding does not necessarily confirm that the virus is endemic or circulating widely within the state. It remains possible that the current patients represent the end of a transmission chain initiated by a traveler, but health officials are still working to map the specific points of contact.

Mpox typically presents in two phases. The initial stage mimics a flu, characterized by fever, chills, fatigue, headache, muscle soreness, and swollen lymph nodes. This is followed by the development of firm or tender lesions. Because some individuals may bypass the initial flu-like symptoms entirely, the rash itself is often the first visible sign of infection. Recovery requires waiting for all lesions to heal, a process that can take anywhere from two to four weeks, during which time the patient remains infectious.

The lack of reported out-of-state travel does not necessarily establish that the monkeypox virus is circulating here in Alaska. They may have had exposure to somebody who traveled to Alaska, and they may be the end of that transmission line at this point. We don’t know. — Dr. Randi Rollins, CDC epidemiologist

National Trends and Vaccine Availability

The emergence of these cases in Anchorage mirrors a broader national trend. Following a lull after the 2022-2023 global outbreak, the CDC has reported an uptick in infections across the United States since March. A key distinction in the current landscape is the genetic makeup of the virus. The strain responsible for the 2022 global outbreak was identified as clade II, whereas the currently circulating virus is identified as clade I. While the clade I variation has historically been associated with higher mortality rates in Central Africa, health officials emphasize that the current version appears to be less severe.

Mpox outbreak prompts health emergency declaration

For those at elevated risk, the JYNNEOS vaccine remains the primary tool for mitigation. Approved by the FDA in 2019, the two-dose series is designed to protect against both clades of mpox as well as smallpox. State records indicate that 851 Alaskans have received their first dose since 2022, with 604 completing the series. Officials are currently encouraging those at higher risk—including men who have sex with men, those with known exposure to the virus, and certain laboratory or healthcare workers—to consult with the Anchorage Health Department or their local provider.

The Persistent Presence of Borealpox

While the focus remains on the mpox outbreak, Alaska health officials are simultaneously tracking a separate, rarer viral disease known as borealpox, formerly referred to as Alaskapox. First identified in Fairbanks in 2015, this disease is related to the pox family but maintains a different transmission cycle, primarily circulating among small mammals like red-backed voles.

Two cases of borealpox have been diagnosed this year, bringing the global total to nine. While the majority of these cases have been mild, the disease carries significant stakes for vulnerable populations. In January 2024, a Kenai Peninsula man with a compromised immune system died after contracting a genetically distinct strain of the virus. Unlike mpox, there is currently no vaccine for borealpox, though researchers are exploring potential antiviral treatments and the development of preventative measures.

As state officials continue to track the source of the Anchorage mpox infections, the focus remains on patient isolation and public awareness. With the virus capable of spreading through various forms of close contact, the current priority is to minimize further transmission while waiting for more data on whether these cases are isolated incidents or part of a persistent local chain.
