New Tick-Borne Threat in California

A new tick-borne illness, Rickettsia lanei, is spreading in Northern California—already confirmed in four people, including one hospitalized in April. This spotted fever group pathogen, carried by American dog and Pacific Coast ticks, causes fever, rash, and potentially life-threatening organ damage, with global fatality rates over 50%. Often mistaken for Rocky Mountain spotted fever, it’s likely underdiagnosed. Thanks to sustained public health investment, detection tools now exist—and awareness is key. Stay safe: cover up outdoors, check for ticks, and protect your pets. Support the show:Get a discount at https://solipillow.com/discount/dnn.
