The
NYTimes is reporting that a new bacteria called "Borrelia miyamotoi" and carried by deer ticks, is being studied as a cause for recurring fevers. Lyme disease, also carried by the ticks, has long been known to cause fatigue and joint pain...but not fevers.
...
While most Lyme victims are cured by a two-week course of antibiotics, some have symptoms that go on for years and believe they have persistent infections that the antibiotics did not reach. Most medical authorities...take the position that “chronic Lyme disease” does not exist...They oppose the solution demanded by some self-proclaimed victims: long-term intravenous antibiotics...
So if you seem to be constantly fighting off a recurring feverish state, you might wish to have your doctor investigate this new bacteria. But I'd have to be pretty sick before I'd demand "long-term intravenous antibiotics."
