Trench fever, also known as quintana fever or Wolhynian fever, is an infectious disease caused by the bacterium Bartonella quintana (formerly
Rickettsia quintana). This disease gained notoriety during World War I when it afflicted soldiers in the trenches, earning its distinctive name.
Trench fever is primarily transmitted through body lice (Pediculus humanus corporis) that serve as vectors. The causative agent of trench fever is Bartonella quintana, a gram-negative aerobic bacterium. This bacterium is transmitted to humans through the feces of infected body lice, which can contaminate open wounds or be rubbed into the eyes or mouth during the lice’s feeding process. The lice act as vectors, carrying the bacteria and facilitating its spread among human hosts. Sources:
Trench fever was first recognized as a distinct disease during World War I when it affected soldiers on both sides of the conflict, particularly those fighting in the trenches of Flanders and France. The disease earned its name due to its association with the poor living conditions and lice infestations common in the trenches. It was responsible for a significant number of casualties among European troops, with an estimated one million cases reported among the Allied forces alone. Sources:
Trench fever has been reported in various regions around the world, particularly in areas with poor sanitation and overcrowded living conditions. During World War I, it was prevalent among soldiers fighting in the trenches of Flanders, France, Poland, Galicia, Italy, Macedonia, and other European fronts. Today, cases of trench fever are still occasionally reported, primarily among homeless and refugee populations, where body lice infestations are more common. Sources:
Trench fever is caused by the bacterium Bartonella quintana, which is transmitted to humans through the feces of infected body lice. The bacteria can enter the body through open wounds, mucous membranes, or even through the lice’s bite site. Once inside the human host, Bartonella quintana can infect various cell types, including endothelial cells and erythrocytes, leading to a systemic
infection. Sources: The primary symptoms of trench fever include sudden onset of fever, headache, intense pain behind the eyes, weakness, sore muscles and joints, shin pain, and dizziness. The fever often occurs in a cyclic pattern, with febrile episodes lasting 5 days followed by afebrile periods of a few days, earning it the nickname “five-day fever.” Other symptoms may include malaise, relapsing fever, and prolonged fatigue. Sources: Diagnosing trench fever can be challenging due to its non-specific clinical findings. However, a combination of clinical symptoms, exposure history, and laboratory tests can aid in the diagnosis. Laboratory tests may include serology for detecting antibodies against Bartonella quintana, as well as molecular techniques like polymerase chain reaction (PCR) to identify the presence of bacterial DNA.

Trench fever is typically treated with antibiotics, such as doxycycline, gentamicin, or ciprofloxacin. The duration of treatment may vary depending on the severity of the
infection and the patient’s response. In addition to antibiotics, supportive care measures like fever management, hydration, and rest may be recommended to alleviate symptoms. Sources: The primary preventive measure against trench fever is controlling body lice infestations and maintaining good personal
hygiene. This includes regularly washing and changing clothes, using insecticides or other lice-control methods, and improving living conditions to reduce overcrowding and unsanitary environments.
Public health strategies focused on vector control, improving sanitation, and raising awareness can also help prevent the spread of trench fever. Sources: While trench fever is generally non-fatal, it can lead to severe complications in some cases. These may include endocarditis, bacillary angiomatosis, and chronic
infections. Patients may also experience prolonged fatigue, weakness, and recurrent fevers, even after completing antibiotic treatment. Additionally, co-
infections with other diseases, such as syphilis, can complicate the clinical course and treatment of trench fever. Sources:
Trench fever is a prime example of the intersection between public health and medical entomology. Understanding the role of body lice as vectors in the transmission of Bartonella quintana is crucial for developing effective prevention and control strategies. Medical entomologists study the biology, behavior, and ecology of lice, as well as their interactions with human hosts and potential disease agents. This knowledge is essential for designing targeted interventions, such as vector control measures and
hygiene education programs. Sources: Ongoing scientific research on trench fever and Bartonella quintana continues to unravel the intricacies of this disease. Recent studies have focused on understanding the pathogenesis, virulence factors, and immune response to Bartonella quintana
infections. Additionally, researchers are exploring new diagnostic techniques, treatment options, and potential vaccine development. The availability of advanced molecular tools and genomic analysis has facilitated the study of this fastidious bacterium, providing insights into its evolution and epidemiology. Sources:
Trench fever is sometimes confused with other louse-borne diseases, such as epidemic typhus and relapsing fever. However, these diseases are caused by distinct pathogens and have different clinical presentations and epidemiological patterns. It is essential to differentiate trench fever from these diseases to ensure appropriate diagnosis and treatment. Comparative studies of these vector-borne illnesses can provide valuable insights into their pathogenesis, transmission dynamics, and potential control measures. Sources:
Trench fever had a significant impact on the soldiers and civilian populations during World War I. The disease added to the already challenging conditions faced by troops in the trenches, contributing to physical and psychological hardships. The widespread nature of the epidemic sparked debates about military
hygiene, living conditions, and the treatment of soldiers. Moreover, the disease became a subject of literary works and personal accounts, capturing the experiences of those affected by this “forgotten fever.” Sources: While trench fever was once primarily associated with wartime conditions, it has not been eradicated. Today, cases continue to occur sporadically, particularly among homeless and refugee populations living in overcrowded and unsanitary conditions. These urban and marginalized communities can experience outbreaks of trench fever due to body lice infestations, highlighting the ongoing public health challenges posed by this disease. Sources:
Trench fever, a disease with a rich historical legacy, continues to be a public health concern in various parts of the world. The role of body lice as vectors and the persistence of unsanitary living conditions contribute to the ongoing occurrence of this disease. While advancements in diagnosis, treatment, and prevention strategies have been made, further research and vigilance are necessary to mitigate the impact of trench fever, particularly in vulnerable populations. Interdisciplinary collaboration between medical professionals, entomologists, and public health experts is crucial for developing comprehensive strategies to combat this forgotten fever and ensure the well-being of affected communities.Trench Fever: Causes, Symptoms, Treatment & Prevention
