In a groundbreaking study, researchers have shed light on the intricate dynamics between leishmaniases - diseases caused by the Leishmania parasites - and their primary vectors: sand flies.

This research, particularly relevant for Europe and its neighboring countries, highlights the ongoing risks posed by these tiny, blood-sucking insects, especially in regions bordering the Mediterranean and Black Sea.

Leishmania species such as Leishmania donovani and Leishmania infantum are notably endemic in these areas, leading to severe health implications for both humans and animals.

Visceral leishmaniasis (VL), primarily associated with L. infantum, poses life-threatening challenges if not treated promptly. Moreover, canine leishmaniasis (CanL), a significant disease impacting dogs, adds to the urgency of understanding this issue further.

Cutaneous leishmaniasis (CL), though often less severe, causes persistent skin lesions and can lead to deep social stigma and disability that impacts daily life and work capabilities.

Alarmingly, the incidence of CL is significantly higher than VL, with endemic zones prevalent in Northern Africa and the Middle East.

The research suggests that understanding the relationship between various Leishmania species and their vectors can provide vital epidemiological insights.
