Background: Visceral leishmaniasis (VL) is one of the most important neglected tropical diseases. The zoonotic form of VL is endemic in some areas of Iran. We aimed to determine the status of VL identified in humans and canines in different parts of Iran from 2013 to 2022.
Method: A national representative cross-sectional study was conducted in 10 provinces of Iran, including the national leishmaniasis reference lab. We employed the direct agglutination test (DAT) as a reliable serological method to detect anti-Leishmania infantum antibodies in humans and animal reservoir hosts. Additionally, a narrative literature review was conducted to identify relevant studies on VL seroprevalence in Iran from 2013 to 2023.
Results: The results of 21281 human and 5610 canine serum samples from 2013 to 2022 are reported. Altogether, 448 (2.1%, 95%CI: 2.0-2.3) human serum samples showed anti-L. infantum antibody levels of ≥1:3200. Of these samples, 13716 (64.5%) were collected actively, which showed a seroprevalence of 0.6% (95% CI: 0.5-0.8) and 7565 (35.5%) were collected passively, which showed a seroprevalence of 4.8% (95%CI: 4.3-5.3). Overall, 1035 (20.1%, 95%CI: 19.0-21.2) of 5160 domestic dogs (Canis familiaris) samples showed anti-L. infantum antibody levels of ≥1:320. Northwest (2.8%) and northeast (0.96%) regions had the highest human VL seroprevalence, while northwest (21.5%) and south (14.4%) regions had the highest canine VL seroprevalence.
Conclusion: Zoonotic VL, an endemic parasitic disease, is still present in several different distinct areas across Iran. While human VL cases have shown a declining trend over the last decade, the prevalence of canine VL remains significant. |
