Intestinal parasitic infections and urbanization

Area of Science:

• Public Health
• Infectious Diseases
• Urbanization

Background:

• A significant portion of developing countries' populations reside in urban slums and shanty towns, a number projected to rise substantially.
• Rapid urbanization leads to increased population density in urban and suburban settings, potentially exacerbating disease transmission.
• Rural-to-urban migration introduces new populations to environments with conditions favorable for parasitic infections.

Purpose of the Study:

• To highlight the potential increase in parasitic infections due to urbanization.
• To emphasize the need for interventions in urban deprived areas.

Main Methods:

• The study reviews population trends and discusses the transmission dynamics of specific parasitic infections.
• It examines the impact of environmental conditions in urban settings on disease prevalence.

Main Results:

• Infections caused by Entamoeba histolytica and Giardia intestinalis, as well as Ascaris lumbricoides and Trichuris trichiura, are likely to increase.
• Favorable transmission conditions in urban and suburban areas heighten the risk for migrating populations.

Conclusions:

• Urgent improvements in sanitation in deprived urban areas are necessary.
• Periodic deworming treatments are recommended to reduce parasitic worm burden, particularly in school-aged children.
