Summary
Visceral leishmaniasis (VL) is increasing in Tunisia, spreading geographically and affecting young children most. Improved diagnosis shortened delays and reduced the lethality rate of this important public health issue.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Context:
- Visceral leishmaniasis (VL) poses a significant public health challenge in Tunisia.
- Previous studies highlighted its presence, but recent epidemiological shifts required updated data.
Purpose:
- To update the epidemiological and clinical features of visceral leishmaniasis in Tunisia.
- To analyze trends in incidence, geographical distribution, and patient demographics.
Summary:
- A retrospective analysis of 1,096 VL cases diagnosed between 1996 and 2006 revealed an increasing incidence rate (1.04/100,000 inhabitants).
- Children under 5 were most affected, with disease spreading from northern to central and southern regions.
- Rural cases predominated, and a reduced diagnostic delay (54 days) contributed to a lower lethality rate (2.9%).
Impact:
- The findings indicate an expanding geographical distribution and increased incidence of VL in Tunisia.
- Environmental factors like irrigation and agriculture may favor vector and reservoir proliferation.
- This study underscores the need for continued surveillance and control strategies for VL in the region.

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:21Antiprotozoal Agents
Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:29Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
