Cutaneous Leishmaniasis Cases Drop in Northwest Libya: New Study Reveals Promising Trend

Northwest Libya Sees Decline in Leishmaniasis Cases Since 2019

A new peer-reviewed study published in the Libya Medical Journal has revealed a significant decline in cutaneous leishmaniasis (CL) cases across northwest Libya, offering hope in the fight against one of the region's most persistent parasitic diseases. The research, which tracked infections from 2019 to 2026, found that overall case numbers dropped from 238 reported instances in 2019 to substantially lower figures in recent years — a trend health experts attribute to improved awareness and vector control efforts.

The study focused on three key districts: Sabratha, Al-Elajilat, and Al-Jamil, all located in the northwestern coastal belt of Libya. Sabratha recorded the highest number of cases throughout the investigation, followed by Al-Elajilat and Al-Jamil. These areas remain endemic zones where the disease continues to pose a serious public health challenge, particularly for children and young adults under 20.

What Is Cutaneous Leishmaniasis and Why Does It Matter?

Cutaneous leishmaniasis is a vector-borne parasitic disease caused by protozoa of the Leishmania major and Leishmania tropica species. The disease is transmitted through the bite of infected female sandflies, which thrive in the warm, arid climates of North Africa's coastal regions.

CL causes skin lesions ranging from small nodules to large, disfiguring ulcers. While rarely fatal, the disease carries a heavy social burden. Lesions often heal slowly over months, leaving permanent scars that carry significant stigma — especially for women and children. The World Health Organization classifies leishmaniasis as a neglected tropical disease, affecting over 1 billion people worldwide.

Key Findings From the Northwest Libya Study

  • 238 cases were recorded in 2019 across the three study districts, with numbers declining steadily through 2026
  • Sabratha had the highest infection rate, making it the primary hotspot for CL transmission in the region
  • Children and young adults under 20 were the most affected demographic group, accounting for the majority of new infections
  • Sandfly vector control programs implemented between 2020 and 2024 appear to have contributed to the declining trend
  • Improved diagnostic capacity at local health centers enabled faster detection and treatment of cases

Expert Voices: "Progress Is Real but Fragile"

Dr. Kaula A. Saad, lead author of the study and a researcher at the University of Tripoli's Faculty of Veterinary Medicine, emphasized that while the declining trend is encouraging, sustained investment is critical. "The reduction in cases demonstrates that targeted interventions — particularly sandfly vector control and community education — can make a measurable difference. However, if these programs are scaled back, we risk a resurgence," the research team noted.

The study also highlighted that treatment practices in the region remain inconsistent. While pentavalent antimonials remain the standard first-line treatment, access to newer therapies such as miltefosine and liposomal amphotericin B remains limited in northwest Libya's public health facilities.

Why This Matters for Libyans

For communities in northwest Libya, this research is more than an academic exercise — it directly affects daily life. Cutaneous leishmaniasis has been endemic in this region for over five decades, with transmission dynamics closely linked to environmental conditions, urbanization patterns, and the presence of animal reservoirs including rodents and stray dogs.

The decline in cases signals that Libya's public health infrastructure, despite years of conflict and instability, is beginning to regain its capacity to monitor and respond to endemic diseases. For families in Sabratha and surrounding areas, fewer children suffering from disfiguring skin lesions means reduced stigma, lower medical costs, and improved quality of life. The study's findings also provide a data-driven foundation for health authorities to allocate resources more effectively and expand vector control programs to emerging foci in other parts of the country.

Looking Ahead: Sustaining the Decline

Health experts recommend three priority actions to maintain the positive trend: expanding sandfly surveillance to new areas, ensuring consistent supply of CL treatments at primary health care centers, and launching community awareness campaigns — especially in schools — about prevention measures such as insecticide-treated nets and protective clothing during evening hours when sandflies are most active.
