Tiene un veneno 15 veces más tóxico que una cobra y 10 veces más potente que la quemadura con ácido sulfúrico. Su nombre se debe a que suele esconderse en grietas, zócalos y lugares de difícil acceso.

Un hombre de 52 años murió tres días después de ser picado en Benavídez, partido de Tigre. Sus síntomas fueron: fiebre alta, decaimiento, náuseas, escalofríos y una lesión necrótica en su mano.

Luego de ser atendido en varios hospitales, los médicos detectaron una hemorragia interna. Finalmente, falleció por un paro cardiorrespiratorio.

La picadura de la “araña de rincón” provoca un intenso dolor, muchas veces descripto como un pinchazo, y luego una sensación de quemazón. No es el primer caso que se detecta en los últimos años.

A principios del 2020, el ataque de este arácnido venenoso dejó en terapia intensiva a una nena de 3 años oriunda de Bahía Blanca que se salvó gracias al antídoto aplicado a tiempo.

“Es uno de los más difíciles de obtener y se distribuye en las provincias, ya que es un araña que se encuentra en todo el país, sobre todo en zonas rurales”, explicó el Director del Instituto Nacional de Producción de Biológicos del Instituto Malbrán.

“El antídoto hay que aplicarlo enseguida, de forma endovenosa, antes de que afecte a los órganos. Si llega a ellos, lo que resta es esperar que el organismo lo elimine por la orina”, señaló el médico.
