Giardiasis is a parasitic infection caused by the protozoa Giardia and remains a significant public health concern globally. Recent advances in understanding Giardia infections in both humans and animals have provided valuable insights into genetic diversity, transmission dynamics, pathogenicity, the relationship with the gut microbiota and drug resistance mechanisms.

Studies have highlighted the zoonotic potential of Giardia, emphasizing the relationship between human and animal health. Diagnostic tools have enhanced detection accuracy, contributing to a better understanding of the epidemiology of the disease. Research efforts continue to explore effective treatment strategies against drug-resistant strains and the environmental persistence of Giardia cysts. These advancements underscore the importance of collaborative One Health approaches to mitigate the impact of Giardia infections on human and animal populations worldwide particularly in endemic areas.

The proposed topic aims to collect and collate current and relevant studies about the biology, epidemiology, diagnostic, therapeutic, and prevention measures of Giardia, focusing on one health approach. Thus, this topic seeks to highlight the importance of collaborative approaches in mitigating the impact of giardiasis on global health.

Potential sub-topics include, but are not limited to:

• General biology of Giardia

• Transmission (food, waterborne -drinking and recreational water, human to human, animal to animal)

• Host-pathogen interactions

• Clinical disease and pathology

• Epidemiology

• Diagnosis and treatment

• Parasitic co-infections and microbial interactions

• Prevention measures

In this article collection, we welcome the following article types: Original research, reviews, mini-reviews, systematic reviews.
