SINGAPORE - When Mrs Cynthia Koh's middle child, Kyler, was admitted to the National University Hospital (NUH) in 2018 at eight months old, he had a persistent fever for days.
It was only after doctors noticed Kyler's skin was a yellowish hue that they did a blood test, revealing he had beta thalassaemia major.
