Worm Infestation: Diagnosis, Treatment and Prevention

Area of Science:

• Public Health
• Infectious Diseases
• Pediatrics

Background:

• Worm infections, including Ascariasis, Trichuriasis, Hookworm, and Enterobiasis, are prevalent in low- and middle-income countries, particularly affecting children.
• In India, over 20% of children are affected by worm infestations, leading to significant health consequences such as growth faltering, anemia, and impaired academic performance.
• Larval or adult worm migration contributes to pulmonary and gastrointestinal morbidity in affected children.

Purpose of the Study:

• To review the distinctive life cycle and clinical features of various worm infections.
• To discuss diagnostic techniques and evolving treatment strategies for worm infestations.
• To highlight the importance of integrated management and identify barriers to achieving global elimination targets for soil-transmitted helminthiasis.

Main Methods:

• Review of distinctive life cycle and clinical features of various worms.
• Discussion of diagnostic techniques, including stool microscopy and the Kato-Katz technique for soil-transmitted helminths (STH).
• Analysis of current and evolving anthelminthic drug armamentarium and integrated management strategies.

Main Results:

• Moderate to heavy worm infestations are linked to adverse health outcomes in children, including nutritional compromise and suboptimal academic performance.
• Stool microscopy and the Kato-Katz technique are key diagnostic methods for worm detection.
• Efficacious broad-spectrum anthelminthics are available, and integrated management strategies are essential.

Conclusions:

• Integrated management, encompassing individualized treatment, mass drug administration, and preventive measures, is vital for controlling worm infestations.
• Addressing barriers to diagnosis, treatment, and prevention is critical for achieving the World Health Organization's (WHO) 75% coverage target for eliminating soil-transmitted helminthiasis in children.
• Effective management strategies are necessary to mitigate the public health impact of worm infections in endemic regions.
