Your brother is really lucky to be alive! I took care of a
patient in the ICU, he came in to us comatose and he had
disseminated intra-vascular bleeding manifested by small red spots
all over his body. He was totally non-responsive to any
stimulii. Bloodwork showed elevated hemorrhaging with darn
low platelet count! I was preparing him for an Emergency
Operation when a doc came and stopped everything - the poor man had
Dengue Hemorrhagic Fever and it was too late to do anything for
him. 
He was pronounced
brain dead.
His wife couldn't take it because just that morning, they were
enjoying breakfast with their two young kids at McD's. Then
at about 9:30am, he collapsed, ambulance came at about 9:45am, and
by the time he reached my ICU at 10:10am, it was already too
late.
They had apparently gone to Thailand for a holiday and he
returned home feeling flu-like symptoms for almost an entire
week. He finally succumbed to the disease, leaving behind a
very stunned wife and two young children who were too young to
understand it all. I think the eldest child was only in
Primary 2 whilst the younger one was in kindergarten.
I felt
sooooo sad for the family and stayed behind to console the wife...
and was promptly reprimanded by my senior for 'wasting time' and
not 'organising my time properly'! 
Yeah for those who don't know the symptoms it's very dangerous
Actually for the 3rd time I didn't have fever or anything or
feel strange
I remember I was sitting in the garden and I happened to glance
down on my legs and I noticed some small red dots on my legs. That
prompted me to get my mum to see a doctor. I didn't have these red
dots before prior but I remembered it was one of the symptoms,
Ya my brother stablised immediately once they gave him a blood
transfusion
