My younger brother , a five years old boy, has a fever with cough but we noticed that their is a little blood inside his phlegm. is this a risk?

AURI: A little blood in the sputum is not at risk.It means his cough is severe to have a little bleeding with it. Does he have cough syrup ?

See below: Blood streaking in the phlegm could be due to a blood nose (epistaxis) that drained to the back of the throat, but it may also be due to other reasons, like a tear in the throat from hard coughing or worse . . . A bronchitis or pneumonia.. Especially if the child is having any breathing difficulty, get him seen asap.
