Trench fever is a clinical syndrome caused by infection with Bartonella quintana; the condition was first described during World War I. Contemporary B quintana disease, commonly referred to as urban trench fever, is typically found in homeless, alcoholic, and poor populations. 2.3% of female population self-reported having Trench fever in Italy 2010. Fever is NOT the disease but is your body fighting the disease, so if you lower the fever you make it harder for the body to fight the bacteria/virus and more likely to get serious complications from the germ.
Erythromycin and azithromycin are both used to treat trench fever. Four weeks of treatment are usually necessary. Inadequate treatment often results in a relapse. In fact, relapses have been reported to occur as long as 10 years after the first episode. Researchers at Great Ormond Street Hospital have in the past claimed tackling a Trench fever with medicine before it is allowed to run its course, may slow recovery time, because the temperature can help to kill the bacteria causing the illness.
