California teacher dies after being bitten by a bat inside her classroom
A central California teacher died last month after she was bitten by a bat that presumably had rabies inside her classroom, officials and a friend of the woman, marking the third such fatality in North America in recent weeks.
In the wake of Leah Seneng’s death on Nov. 22, public health officials are warning the public about the dangers of bats, which are the most common source of human rabies in the U.S. Even though fewer than 10 people in the country die from rabies each year, it is almost always fatal if not treated quickly.
Seneng, 60, found a bat in her classroom in mid-October, her friend Laura Splotch told KFSN-TV. She tried to scoop it up and take it outside but it bit her, Splotch said.
Seneng did not immediately have symptoms of rabies but she fell ill weeks later and was taken to the hospital, where she was put into a medically-induced coma and died days later, Splotch told the TV station.
“It’s devastating to see her in that state, with all the machines hooked up and everything, it was pretty upsetting and scary,” Splotch told KFSN.
According to her Facebook profile, Seneng was an art teacher at Bryant Middle School in Dos Palos, California. The Dos Palos-Oro Loma Joint Unified School District, called Seneng “a dedicated and compassionate educator.”
“We were shocked to learn that Leah’s passing was related to contracting rabies, most likely from being bitten by a bat and we are cooperating with the Merced County Department of Public Health on their investigation,” the school district said in a statement. “We live and work in a community known to have bats and other wildlife around school grounds, and we will continue to help educate our community regarding the dangers associated with coming into direct contact with any wild animal, including bats.”
Merced County confirmed the rabies exposure but, due to privacy laws, did not release the deceased’s name. The California Department of Public Health confirmed that the victim died after contracting rabies.
“Bites from bats can be incredibly small and difficult to see or to detect. It is important to wash your hands and look for any open wounds after touching a wild animal, and to seek immediate medical care if bitten,” CDPH Director Dr. Tomás J. Aragón said in a statement. “It is always safest to leave wild animals alone. Do not approach, touch, or try to feed any animals that you don’t know.”
At least two other people in North America have died of rabies after encountering a bat in recent weeks. Last month, health officials in Canada announced that a child died from rabies after being exposed to a bat in their room. About a week before that, officials announced a U.S. citizen died from rabies after being exposed to a bat in western Minnesota in July.
How is rabies spread and what are the symptoms?
Rabies is a deadly viral infection that attacks the nervous system in humans and animals, causing brain and spinal cord inflammation. It is typically spread to humans through direct contact with the saliva of an infected animal through scratching or biting.
Rabies is commonly found in bats, raccoons, foxes, skunks and some household pets. Without proper and prompt treatment after symptoms appear, rabies is nearly 100 percent fatal in both animals and humans, according to Haldimand and Norfolk Health Services, where the child was admitted.
Treatment has proven to be nearly 100% effective at preventing the disease if someone is exposed, though it must start before symptoms appear.
Bats pose a unique risk because their scratches can be hard to notice due to their small teeth, and bats cannot be vaccinated through provincial programs, health officials said.
If bitten by an animal suspected of carrying the virus, health officials advise washing the wound thoroughly with soap and water for 15 minutes and immediately seeking medical attention.
According to the CDC, the incubation period of rabies may last from weeks to months, depending on the location of exposure, severity of exposure and age.
“The first symptoms of rabies, called prodrome, maybe like the flu, including weakness, discomfort, fever, or headache. There also may be discomfort, prickling, or an itching sensation at the site of the bite. These symptoms may last for several days,” the CDC says.

Arctic tundra becoming a source of carbon dioxide emissions, NOAA warns
Foreboding environmental milestones abounded again this year in the Arctic, where experts say dramatic climate shifts are fundamentally altering the ecosystem and how it operates. One recent turning point for the region involves its carbon footprint: Where conditions in the Arctic historically worked to reduce global emissions, they’re now actively contributing to them.
That’s a major transition that could reap consequences on human, plant and animal life far beyond Earth’s northernmost arena, warned a cohort of scientists whose research appears in the National Oceanic and Atmospheric Administration’s 2024 Arctic Report Card, published Tuesday. The report is an annual assessment of the polar environment, which in recent years has become a stark alert signal marked by unprecedented and ominous observations all linked to rising temperatures from human-caused climate change.
A focus of the latest Arctic evaluation was the effects of warmer weather and wildfires on the tundra, a far-northern biome that’s typically known for extreme cold, little precipitation and a layer of permanently frozen soil, called permafrost, covering the land. Those traits collectively made the Arctic an important carbon sink for millennia, meaning the region essentially helped reduce carbon dioxide emissions worldwide by absorbing more carbon than it emitted into the atmosphere.
That has mainly been due to carbon uptake from plants, which regulate atmospheric levels of the molecule through photosynthesis, and a storage process in the permafrost, which traps carbon dioxide in the ground. But warming air temperatures in the Arctic are breaking down permafrost across the tundra, in some cases, severely. The Arctic report, for example, showed Alaskan permafrost temperatures in 2024 were the second-warmest ever recorded. That causes the soil to heat up and thaw, its carbon repositories decompose along with it.
Research included in NOAA’s Arctic report shows carbon once stored in the tundra’s permafrost is actually being released into the atmosphere. In parts of the region, it’s happening at a rate that outweighs the carbon sink and instead creates a net increase in greenhouse gas emissions — something of particular concern to climate scientists at a time when pollution from fossil fuel production has already reached a record high.
The same fossil fuels overwhelming the atmosphere and prompting ongoing admonition from top weather and climate officials at the United Nations are fueling the emissions in the Arctic, said Rich Spinrad, the administrator of NOAA, in a statement on the new report’s findings.
“Our observations now show that the Arctic tundra, which is experiencing warming and increased wildfire, is now emitting more carbon than it stores, which will worsen climate change impacts,” Spinrad said. “This is yet one more sign, predicted by scientists, of the consequences of inadequately reducing fossil fuel pollution.”
Wildfires in the Arctic have been raging at rates never seen before, and that alone drives up carbon emissions. Researchers suggest 2024 had the second-highest annual volume of wildfire emissions north of the Arctic Circle on record. Coupled with the release of carbon dioxide and methane gas from permafrost stores, they say net emissions could continue to increase in the place that climate change is heating up faster than anywhere else on the planet.
