Disease-bearing ticks thrive as climate change heats up US

Blood-sucking ticks can spread Lyme disease and are extending beyond their traditional north-eastern range

Growing up in north-eastern Ohio, Kimberly Byce spent much of her childhood running around in the woods, with the greatest threat being mosquito bites or sunburn. She can't remember her parents ever uttering the word tick". And yet, in adulthood, disease-laden ticks now blight her family's life.

Byce's husband Trent Beers has been struck down by Lyme disease twice in the past year, initially misdiagnosed after suffering back pain so bad he couldn't emerge from bed, drenched from night sweats and his mind a fog of confusion. Their sons Arbor, four, and Abbott, seven, were struck down by raging fevers initially thought to be related to coronavirus, but subsequently confirmed to also be from Lyme disease.
