疾
jí
(bound form) disease; ailment
(bound form) swift; (literary) to hate; to abhor
sickness (疒) + arrow (矢) = disease that strikes swiftly
疒 is the sickness radical, framing 疾 as a disease concept. 矢 (arrow) mainly contributes the sound jí, though the image of an arrow piercing the body may have motivated the character's secondary meaning of swiftness.

tā dé le yī zhǒng guài jí, yī shēng yě bù zhī dào zěn me zhì。
He came down with a strange disease, and even the doctor did not know how to treat it.
