Event details

Wildlife officials are sounding the alarm, after determining several dead harbor seals found in the north Puget Sound had bird flu. It’s believed that avian influenza jumped from wild birds in the Salish Sea to local harbor seals. That’s after three adult seals tested positive for the virus in mid-August, according to a report from the National Oceanic Atmospheric Administration (NOAA). The press release was also linked in a NOAA social media post. This is as an ongoing outbreak of avian flu has affected wild populations of seabirds around Rat Island and Marrowstone Island. Katie Haman, a wildlife veterinarian with the Washington Department of Fish and Wildlife, recently recovered 1,600 dead birds in the area and said that she was trying to minimize exposure to the seals, among other mammals. “I think the fact that we only had five, I would like to think that number was lower than it could have been because we were out collecting the carcasses and hopefully reducing that the transmission,” Haman said. “I hope that we are we’re in the clear, at least in the transmission from the birds to the mammals.” Currently, evidence shows the virus is spreading directly from birds to seals and is not being spread from seal to seal. That’s important as a mammal-to-mammal spread could mean a higher risk of the virus spreading to humans. Bird flu can infect humans, but health officials say that risk is low. “The discovery of HPAI H5N1 in seals brings to light the potential for cross-species transmission and highlights the complexity of managing infectious diseases in wildlife populations,” says Kristin Wilkinson, NOAA Fisheries’ regional stranding and entanglement coordinator said in a report. Even so, beachgoers are urged to keep themselves and their pets away from animal carcasses. If you encounter sick, injured, or dead seals, call the West Coast Region Stranding Hotline at (866) 767-6114, and the Washington State Department of Health is advising residents not to touch the dead bird. On the East Coast, however, about 500 gray and harbor seals have died from bird flu around the coast of Maine. NOAA declared an unusual mortality event for the area due to the unexpectedly high volume of deaths. Last winter, an outbreak of bird flu occurred in the domestic population in commercial poultry farms, causing price spikes for eggs and meat, and forcing the euthanasia of more than 47 million chickens and turkeys. This isn’t the first instance of bird flu among local animals in Washington in 2023. In January, an outbreak forced a Monroe farm to shut down for the rest of the year. That led to a mass culling of nearly 200 ducks. In July, bird flu was found in birds and seals near Jefferson County’s Fort Flagler State Park.

Additional information
Symptoms:H5N1 is a type of influenza virus that causes a highly infectious, severe respiratory disease in birds called avian influenza (or "bird flu"). Human cases of H5N1 avian influenza occur occasionally, but it is difficult to transmit the infection from person to person. When people do become infected, the mortality rate is about 60%. Almost all cases of H5N1 infection in people have been associated with close contact with infected live or dead birds, or H5N1-contaminated environments. The virus does not infect humans easily, and spread from person to person appears to be unusual. There is no evidence that the disease can be spread to people through properly prepared and thoroughly cooked food. In most cases, avian influenza in humans develops into a serious disease that should be treated promptly in the hospital and may require intensive care, where available. The antiviral medicine oseltamivir can reduce the severity of illness and prevent death, and should be used in all cases.
