When starts the critical/danger period for a person with dengue haemorrhagic fever?
48-72 hours from the moment body temperature becomes normal (no fever). It’s important to record in a piece of paper and monitor temperature quite often, perhaps every 3 hours from the beginning. The period is called critical or dangerous since the rate of fall of blood platelets within 72 hours is still very much unpredictable and death occurs at this stage.
