Warm temperatures and a mild winter have created ideal conditions for fleas across Louisiana, and health experts say the increase in flea activity also raises concerns about flea-borne illnesses.
Infectious disease specialist MarkAlain Dery says flea populations appear especially active this season.
“With a milder winter and hotter summer conditions, flea swarms are very robust,” Déry said.
One illness tied to infected fleas is flea-borne typhus, a bacterial disease that can cause fever, headaches, body aches, chills, and fatigue.
While cases remain relatively uncommon, Déry says awareness and prevention are important.
“There is cause for concern, particularly when flea populations increase,” he said.
Déry says the best defense starts with flea control both inside and outside the home.
That includes treating pets, maintaining yards, and addressing flea infestations quickly before they spread.
“Abatement is key,” he said.
If symptoms develop after flea exposure, Déry encourages people to seek medical care promptly.
“A trip to the emergency room and an antibiotic regimen will generally take care of it,” he said.
Doctors say while the illness can sound alarming, most cases respond well to treatment when caught early.
For Louisiana residents already battling mosquitoes, termites, and other summertime pests, experts say flea prevention now deserves a little extra attention too.
