Resumen
Las infecciones por helmintos transmitidas por el suelo, como la ascariasis, la tricuriasis y el gusano de gancho, afectan el desarrollo infantil. Si bien los antihelmínticos benzimidazoles son comunes, las preocupaciones sobre la resistencia impulsan la búsqueda de nuevas herramientas de control.
Área de la Ciencia:
- * Parasitología médica.
- * Salud mundial * Salud global es la salud mundial.
- * Enfermedades Infecciosas Pediátricas
Sus antecedentes:
- * Las infecciones por helmintos transmitidas por el suelo (STH), incluidas la ascariasis, la tricuriasis y el gusano de gancho, son frecuentes en niños en entornos de bajos recursos.
- * Estas infecciones pueden conducir a deficiencias significativas en el desarrollo físico, intelectual y cognitivo.
- * Las infecciones por STH representan una carga sustancial para la salud mundial, afectando particularmente a las poblaciones vulnerables.
Objetivo del estudio:
- * Revisar el panorama actual de las infecciones de STH y su manejo.
- * Para resaltar el papel de los antihelmínticos benzimidazol en el tratamiento y la prevención.
- * Para abordar las preocupaciones emergentes con respecto a la resistencia a los medicamentos y la necesidad de nuevas estrategias de control.
Principales métodos:
- * Revisión de la literatura sobre la epidemiología de STH, el impacto clínico y las modalidades de tratamiento.
- * Análisis de los datos sobre la eficacia de los antihelmínticos benzimidazol (mebendazol, albendazol).
- * Examen de los desafíos actuales, incluida la resistencia a los medicamentos y la sostenibilidad de los programas de control.
Principales resultados:
- * Los antihelmínticos benzimidazoles son ampliamente utilizados para el tratamiento y la prevención de las infecciones por HTS en niños.
- * Los programas de desparasitación han demostrado impactos positivos en la salud infantil y los resultados educativos.
- * Existen crecientes preocupaciones con respecto a la sostenibilidad de las actuales estrategias de desparasitación y el potencial de resistencia a los antihelmínticos.
Conclusiones:
- * Las infecciones por STH siguen siendo un problema crítico de salud pública, que requiere medidas de control efectivas.
- * Si bien los antihelmínticos actuales son valiosos, el surgimiento de la resistencia subraya la necesidad urgente de herramientas de control alternativas y complementarias.
- * La investigación continua y el desarrollo de nuevas intervenciones son cruciales para el control a largo plazo de las STH y la mejora del bienestar infantil.

01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Reservoir of Infection
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
01:24Transmission of Pathogens
Pathogens spread from their reservoirs to susceptible hosts through three main routes: contact transmission, vehicle transmission, and vector transmission. Each route involves distinct mechanisms of transfer.Contact TransmissionThis category includes direct contact, indirect contact, and droplet transmission:Direct contact involves immediate physical interaction between individuals—such as a handshake—which can spread pathogens like Streptococcus pyogenes, the bacterium responsible for...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
