“…This figure is the same in both urban and rural areas (The World Bank, 2016g). It has led to a range of different problems, including the spread of diarrhoeal diseases (Inter-American Development Bank, 2011) and parasitic infections (Chew and Lew, 2008; Gutierrez-Jimenez et al , 2013; Huerta et al , 2008; Monárrez-Espino et al , 2011). These health issues invariably hamper any ambitious human development projects.…”

Purpose The purpose of this paper is to explore water management practices in four criteria – access to potable water; despoilment or pollution levels; grade of sanitation architecture; and grade of delivery architecture – in a variety of different Latin American and European nations to establish techniques that are currently been utilised in Europe that could improve water management in Latin America. Design/methodology/approach A systematic review of the available literature on water management in Europe and Latin America is performed to uncover differences and similarities in Latin American and European nations. The documents find are mostly recent, ranging from the last five years (2012-2016). Findings Some best practices from Europe cannot be applied in Latin America due to lack of funding. Fortunately, this is likely to change, as many Latin American nations’ economies are rapidly improving. Tentative recommendations include installing a system of pipeline that passes through all rural areas, and governments partnering with local businesses to provide sanitation, and regular sanitation and environmental inspections to minimise water pollution. It is also advisable for serious consideration to be given to achieving a measure of universality vis-à-vis water management standards across Latin America. Originality/value There is limited information in literature on the analysis of water management in Europe and Latin America, so this paper serves as a reference to fill the gaps, mainly in Latin America because that region is in development compared to European countries with advanced water systems.

“…Without sufficient antiparasitic therapy, what may initially be just a simple intestinal parasitic infection can later develop into severe infections resulted in severe disability with cognitive, mental and behavioral sequalae [7,8]. Children are very prone and they often encounter re-infection [9,10]. Parasitologically, this persistent infection can be maintained by several factors, and these will be the focus of this review.…”

Aim: To discuss about the specific characteristics of intestinal parasitic infection that contributes to the formation of stunting. Discussion: Intestinal parasites infection (IPI) are one of the global utmost health dilemmas, because they put certain vulnerable member of the population, e.g., children, in danger. Global prevalence rate of IPI varied from 30-60%, especially in developing countries located within the region of tropical and subtropical zone that create a definite public health burden, particularly in low- and middle-income countries, including Indonesia. Basically, IPI divided into helminths- and protozoans; each have different and unique characteristics with helminths have a more sophisticated life cycle compare to protozoan. IPI tends to be chronic and sub-clinical, due to the evasion the host's immune system. This chronic IPI affects the host, directly and indirectly, and in long term when it happen during toddlerhood, it contributes to the formation of undernourishment and stunting via certain pathways. Transmission occurs mainly via food contamination; and it is usually always related with daily socio-economic activity. Persistent transmission exists when source of infection available and practice of poor hygiene supports continuous contamination in the environment. By knowing the details of the life cycle of each gastrointestinal parasite, all stake holder can participate in communal effort to break the chain of transmission. Conclusion: The presence of infected individuals with poor hygiene practice is the main contributor to the existence of persistent transmission in certain environment and this can then play a role in the formation of stunting.

“…In parasitology, the inclusion of different diagnosis methods depends on each parasite, considering the biological and morphological variability of the microorganism to be examined. There are several qualitative and quantitative methods for parasitological diagnosis, such as Spontaneous sedimentation method of Hofmman and Lutz; Centrifugal-flotation method of Faust; Staining methods of Ziehl Neelzen and Kato Katz and Sedimentation and centrifugation method of Ritchie [7, 8]. …”

Latin America, Africa, and Asia present wide dissemination and high prevalence rates of waterborne parasitic diseases, which is a strong indicative of the fragility of public sanitation systems. In this context, parasitological analyses represent extremely relevant instruments. Several parasite diagnosis methods exist, among which Ritchie's method (1948) stands out. This method uses formaldehyde and ether, two reagents of toxicological importance that can cause damages to environmental and occupational health. The present study aimed to compare Ritchie's method modified by Régis Anécimo, without use of solvents, with the traditional Ritchie's method, routinely used for helminth and protozoa diagnosing in Brazil. Some changes were introduced in the modified method, such as controlled increase of water temperature used after stool dilution and substitution of formaldehyde and ether by a neutral detergent before material centrifugation for observation of parasites. In examined samples by both methods, multiple infections were commonly observed; the modified method presented a similar sensitivity to identify the parasites. The development of analytic diagnosis methods that minimize the use of chemical products like ether and formaldehyde represents an important tool to prevent occupational diseases among exposed professionals, as well as to preserve environmental quality through the use of clean techniques.

Intervention to prevent intestinal parasitic reinfections among Tarahumara indigenous schoolchildren in northern Mexico

Abstract: Infection/reinfection rates were similar at the schools after 20 weeks. Supervised treatment alone every semester could effectively control AL/GL infections in this indigenous setting.
