Frequently Asked Questions
What Is Called A ‘Breakbone Fever’?
“Breakbone fever” is a common name for dengue because severe muscle, joint, bone, and headache pain can make movement extremely uncomfortable during the illness.
How Long Does Dengue Fever Last?
Dengue fever usually lasts 7 to 10 days, though the high-fever phase typically lasts 2 to 7 days.
Can Dengue Occur More Than Once?
A person can develop it more than once because infection with one virus type does not fully protect against other types.
Which body part is most affected by dengue?
Dengue does not affect one specific body part; it primarily affects the blood system, bone marrow, and liver, causing changes that can lead to bleeding and other complications.
Can Fever Always Indicate Dengue?
Fever can result from many infections and illnesses. Dengue becomes more likely when fever occurs with symptoms such as severe headache, body pain, nausea, or rash.
