At Uptown Dog Park in Long Beach, dog owners were shocked to hear about the outbreak in their area.

Authorities said flea-borne typhus only makes humans sick, not animals. Feral rats, possums and cats can carry the disease.

“I’ve seen raccoons, possums, and yeah, cats, and they’re all just out and about,” said pet owner Gary O’Callaghan.

A flea on one of those stray animals can jump on pets and then be transferred onto humans.

Symptoms include fever, chills, headache, rash, vomiting and muscle pain.

  • Make sure cats and dogs are free of fleas
  • Don’t leave food outdoors
  • Don’t feed wild animals
  • Avoid debris and overgrown vegetation that may attract wild animals
  • Store trash in cans with secure lids
  • Use insect repel repellent
