A Surge in Animal Infections Prompts Action

Maine health officials are considering declaring a public health emergency following an uptick in mosquito-borne illnesses affecting animals across the state. On Friday, the Maine Department of Agriculture and the Maine CDC confirmed a third case of eastern equine encephalitis (EEE) in a horse from Somerset County. This follows two earlier cases in emus from Penobscot County and the detection of West Nile virus in 15 wild birds.

If approved, this would mark Maine’s first-ever public health emergency declaration for mosquito-borne illnesses. While the declaration wouldn't be as far-reaching as the COVID-19 state of emergency, it would allow municipalities to more rapidly implement safety measures, including obtaining necessary permits for prevention efforts.

Climate Change Linked to Rising Disease Risk

Health experts warn that the increase in mosquito-borne illnesses like EEE and West Nile virus may be tied to climate change. Warmer temperatures and extended falls give mosquitoes more time to breed, resulting in higher transmission rates. “Longer warm seasons are creating more opportunities for mosquitoes to spread these viruses,” noted Haris Sohail, an epidemiologist with Maine CDC, at a recent town hall.

In 2023, the state recorded 17 cases of EEE and three of West Nile virus in animals. While confirmed human cases remain rare, the growing number of infections in wildlife has raised concerns about public safety.

Protecting Yourself from Mosquitoes

Although human infections of mosquito-borne illnesses are infrequent in Maine, it’s still important to take precautions. According to the CDC, you can protect yourself by using EPA-approved insect repellents containing DEET, Picaridin, or oil of lemon eucalyptus. The CDC also advises wearing long sleeves, limiting outdoor activity between dusk and dawn when mosquitoes are most active, and eliminating standing water near your home to reduce breeding grounds.

Local residents are already adjusting their routines. “We use DEET and citronella when we’re outside, especially with the kids,” said Heather Walsen, a Portland resident who frequently visits Deering Oaks Park with her family. Others, like Ignacio Gomez from Brunswick, opt for natural repellents like lemongrass oil when working or walking outside.

Increased Public Awareness

Despite the uptick in cases, some residents admit they are more concerned about tick-borne illnesses than mosquito-borne diseases. “We do bug checks on the kids every night,” said Aaron Walsen, while acknowledging that mosquito-borne illnesses are still on their radar.

While many people who contract mosquito-borne illnesses experience mild symptoms or none at all, more severe cases can lead to disorientation, brain inflammation, and even death. Experts warn that up to 50% of people who survive severe infections could suffer lifelong complications.

With mosquito populations likely to increase due to climate changes, officials are urging the public to stay informed and cautious as Maine prepares for a new level of response to these growing health threats.
