Two days ill and Sudden deith

My 15 years old cousin feels breathing problem so admited in hospital at 12:30am. BP 11O/90, PR 130, TEMP 98. She given oxygen and fluid. At 2:30am she started shouting and look like abnormal so she given injection to sleep. Morning 10:00am tests like CBC  conducted. At 1:00pm doctor said that WBC is 40000 and need to shift nearest city hyderabad's hospital. But on the way at 6:00pm she found died.

Q 3. Any relation between WBC and blood cancer?
Q 4. How it is possible a healthy person die after two days of ill?

  Hi I am not a Dr but I just heard of a case similar where the young man was in college was fine then developed a temp...was taken to the hospital with breathing issues...and in less then 48 hours was pronounced dead....this young man contracted meningitis....

Not being in the medical profession I  do not know what the WBC and all would be for meningitis....

I am so sorry for ur loss.
