Larva migratoria - Overview

Nombres alternativos

Larva migratoria cutánea; Ancylostoma braziliense

Definición:

Es una infección con larvas del anquilostoma de perro o gato.

Causas, incidencia y factores de riesgo:

Los huevos de anquilostoma se encuentran en las heces de gatos y perros infectados. Cuando los huevos eclosionan, las larvas infestan cualquier suelo y vegetación contaminados.

Cuando usted entra en contacto con este suelo infestado, las larvas se entierran dentro de la piel, causando una respuesta inflamatoria intensa que lleva a que se presente erupción y una fuerte picazón.

La larva migratoria es más común en países con climas cálidos y afecta más a los niños que a los adultos. En los Estados Unidos, los estados del sudeste presentan las tasas más altas de infección. El principal factor de riesgo para esta enfermedad es el contacto con suelo arenoso y húmedo contaminado con heces de gato y perro.
