Dengue fever is usually transmitted by mosquitoes (Aedes aegypti). However, nosocomial spread can rarely occur by other routes.
Routes of nosocomial spread of dengue:
(1) needlestick
(2) mucocutaneous contact with blood
(3) intranasal or oral mucosal contact with an aerosol, especially in a laboratory
(4) blood transfusion
(5) organ transplantation
(6) in utero (vertical to a fetus)
In theory spread to an infant via breast milk is possible but this has never been documented.
Spread can be prevented by placing the patient in contact isolation and using appropriate personal protective equipment.
Differential diagnosis:
(1) mosquito bite in an endemic area
