Summary
Infections caused 87% of fevers in a Kinshasa study. Malaria was the most common cause, affecting half of patients, while tuberculosis occurred in 15% of inpatients.
Area of Science:
- Infectious Diseases
- Internal Medicine
- Epidemiology
Background:
- Fever is a common symptom with diverse etiologies.
- Identifying the primary causes of fever is crucial for effective clinical management and public health strategies.
- Previous studies in sub-Saharan Africa highlight the prevalence of infectious causes of fever.
Purpose of the Study:
- To prospectively investigate and identify the etiological agents responsible for fever in adult patients.
- To determine the relative frequency of different causes of fever in a hospital setting in Kinshasa, Zaire.
- To provide data that can inform diagnostic and treatment protocols for febrile illnesses in the region.
Main Methods:
- A prospective study was conducted on 300 adult patients presenting with fever.
- Patients included both inpatients and outpatients at Kinshasa Teaching Hospital.
- Data collection focused on identifying the underlying causes of fever for each participant.
Main Results:
- Infection was identified as the predominant cause of fever, accounting for 87% of cases.
- Malaria was the most frequent febrile illness, diagnosed in approximately 50% of patients.
- Tuberculosis was observed in 15% of the hospitalized patients.
- Non-infectious causes, such as connective tissue diseases and neoplasms, were found to be rare.
Conclusions:
- Infectious agents are the primary drivers of fever in the studied adult population in Kinshasa.
- Malaria represents a significant public health burden, being the leading cause of febrile illness.
- The findings underscore the importance of diagnostic efforts focused on infections, particularly malaria and tuberculosis, in febrile patients in this region.
