A maioria das pessoas com alterações por Ascaris é assintomática. Uma pequena proporção de pessoas infectadas desenvolve sintomas pulmonares durante a segunda semana após a ingestão de ovos, quando as larvas invadem o tecido pulmonar e provocam uma resposta de hipersensibilidade imunomediada. Os sintomas incluem tosse não produtiva, desconforto no peito, febre e eosinofilia que costuma desaparecer quando os vermes atingem a maturidade. Em casos graves, os pacientes desenvolvem dispneia e pneumonia eosinofílica (síndrome de Löffler) com infiltrados irregulares transitórios observados nas radiografias. | |||
