Angiostrongyliasis: A Comprehensive Guide

Angiostrongyliasis is an infection that is caused by roundworms in the kidney and alimentary tract. Since these round worms belong to the Angiostrongylus family, the infection is so named. In human beings this infection can result in eosinophilic meningitis and meningoencephalitis.

While you may find that most cases of Angiostrongyliasis are cured without much treatment, sometimes the infection can be too severe causing damage to the central nervous system. You may even hear of death in case of severe infection caused by too much nematode parasite.
