Are you prone to nose bleeding?
If you answer no, then does this nose bleeding come on
spontaneously?
If you answer yes, are there bleeding from the gums?
If you answer yes, it is highly likely that you are suffering from
dengue hemorrhagic fever.
The capillaries (tiniest blood vessels) are present in abundance in
the nose and the gum which leads to spontaneous bleeding if the
vessel walls are disrupted (as in dengue fever).
Other places that you may see blood includes vomiting blood,
passing out dark black tarry smelly stools, and if you are a lady,
passing out more than usual amount of menstrual blood.
