Congenital Chagas disease known as a neglected tropical disease can,
however, be considered as an ecological model of multiple and complex interactions
between parasites, the pregnant woman, placenta, and the unborn child. Indeed,
congenital infection is a rather rare event, it can, however, occur and be found in any
part of the world and the lack of a well-established surveillance program means that the
diagnosis can probably be easily missed putting both the pregnant mother and the fetus,
with the newborn at risk. In this era of globalization with the ongoing European
immigration policies, Congenital Chagas disease would no longer become confined to
only poor rural areas and endemic countries, eventually becoming a significant public
health concern. Bearing this in mind, the possibility of Chagasic disease, in general,
becoming the new human immunodeficiency virus in third world African countries and
developing African nations in the foreseeable future is inevitable. The simple fact that
both the policymakers, and the health care providers are ignorant of the disease and
also lack both the technical knowledge and understanding of the disease modes of
transmission, progression, pathology, and its pathophysiology make it futuristically
possible. This chapter aims to discuss the presenting global challenge of this neglected
tropical disease, its ecological interactions and also try to better understand the
mechanisms sequentially associated with the transmission of live parasites from
maternal blood and the development of congenital infection (asymptomatic) or
congenital Chagas disease (symptomatic) in the fetus and newborns (in both endemic
and non-endemic areas).
