Scientists have discovered a new illness similar to Lyme disease, spread by ticks and resistant to antibiotics, raising fears about growing numbers of people succumbing to debilitating symptoms. Like Lyme disease, the new disease causes headache, fatigue and muscle aches, along with a recurrent fever which returns despite initially appearing to have been cured.The new illness, which has yet to be named, is feared to be less responsive to antibiotic treatment than other tick-borne diseases.Stella Huyshe-Shires, of Lyme Disease Action, said: "We know this new disease, caused by the recently identified bacteria Borrelia miyamotoi, is in the UK. To date it has only been found in a handful of ticks, but it will sound alarm bells."The difficulty about this bacterium is that it causes a relapsing fever so can be misdiagnosed as flu, and those patients run the risk of more serious consequences." ..
