dengue

The fever starts abruptly and is typically high
grade, then goes off for a day or two, only to
return with a vengeance, giving it the name of
“saddle back” fever, as it has two highs with a
dip in between.

Clinically, symptoms start 6 days after of infection as
malaise and headache, followed by sudden onset of fever,
intense backache and generalized pains, mainly in the
orbital and periarticular areas. After an afebrile interval
of 24 to 48 hours, there is recurrence of fever for a day or
two (‘saddleback fever’). There may be skin rash and
lymphadenopathy.
