Question 1

What is dengue fever and how does it spread?

Accepted Answer

Dengue fever is a viral infection caused by one of four dengue virus serotypes, transmitted to humans through the bite of infected Aedes mosquitoes (typically Aedes aegypti or Aedes albopictus). It is not spread directly from person to person.

Can dengue fever be deadly?

Accepted Answer

Yes. Dengue can progress to severe dengue (also known as dengue hemorrhagic fever or dengue shock syndrome), which may be life-threatening. With early recognition and supportive medical care, most cases recover fully.

Question 3

Are dengue and malaria the same?

Accepted Answer

No, dengue and malaria are different diseases. Dengue is caused by a virus and spread by Aedes mosquitoes, while malaria is caused by a parasite and transmitted by Anopheles mosquitoes. Both can cause fever and flu-like symptoms.

Question 4

Can dengue fever come back after recovery?

Accepted Answer

Yes, a person can get dengue more than once. There are four different dengue virus serotypes, and infection with one does not provide long-term immunity against the others.

Question 5

What do dengue mosquito bites look like?

Accepted Answer

Dengue mosquito bites often appear as small, red, itchy bumps. These bites are typically not painful but can become irritated due to scratching.

Question 6

When are dengue mosquitoes most active?

Accepted Answer

Aedes mosquitoes that spread dengue are most active during early morning and late afternoon, especially around sunrise and sunset. They can also bite indoors.

Question 7

What are the symptoms of dengue fever?

Accepted Answer

Symptoms typically begin within 3–14 days, commonly lasting 2–7 days, and include high fever, severe headache, pain behind the eyes, muscle/joint pain, rash, nausea, and thrombocytopenia. Severe cases may involve bleeding, plasma leakage, and shock. Source: CDC Yellow Book – Clinical Presentation & Warning Signs

Question 8

Can dengue fever be cured?

Accepted Answer

No. There is no specific antiviral treatment. Management is supportive, focusing on hydration, fever management (avoid aspirin/NSAIDs), and monitoring for warning signs of severe dengue.

Question 9

How can dengue fever be prevented?

Accepted Answer

Prevention includes avoiding mosquito bites by using insect repellent, wearing long sleeves, using mosquito nets, and eliminating standing water where mosquitoes breed.

Question 10

Are dengue and yellow fever the same?

Accepted Answer

No. Although both are mosquito-borne viruses, dengue and yellow fever are caused by different viruses. Yellow fever has an available vaccine, whereas dengue vaccines have limited use and are not broadly recommended in the U.S.
