Current state of infection and prevalence of giardiasis in Malaysia: a review of 20 years of research.

Background: Giardiasis is a neglected parasitic zoonotic disease caused by that is often overlooked despite the damage inflicted upon humans and domestic/wild animals. Lack of surveillance studies, low sensitivity of diagnostic tools, and resistance to giardiasis treatment add to the challenge in managing giardiasis, leaving a gap that continues to render giardiasis a silent threat to public health worldwide. This situation is not much different in Malaysia, where giardiasis remains a public health problem, especially in the indigenous communities.
