What is dengue and why should we worry about it?

Dengue is a disease caused by a virus spread by mosquitoes. It can make people very sick, with symptoms like high fever, severe headaches, pain behind the eyes, joint and muscle pain, fatigue, nausea, and skin rash. Severe dengue can be life-threatening. Since it’s common in many parts of the world, protecting against it is important.

 

What is Qdenga?

Qdenga is a new vaccine designed to prevent dengue. Unlike some older vaccines, Qdenga can be used in people who have never had dengue before, as well as those who have.

 

Who can take Qdenga?

Qdenga is suitable for both children and adults, but the exact age range for who can take it depends on health guidelines in different countries.

 

How well does Qdenga work?

Qdenga has shown good results in protecting against dengue in clinical trials. However, its effectiveness can vary depending on the type of dengue virus and if the person getting the vaccine has had dengue before.

 

How is Qdenga given?

Qdenga is given in a series of two shots separated over a three-month period. Short Notice Travel: Even if you don’t have three months before traveling, getting at least one shot is beneficial. One dose of Qdenga offers about 81% defence against all types of dengue virus until you can get the second shot. For those making last-minute travel plans, it’s still worthwhile to get vaccinated. Enhanced Protection: After receiving the second Qdenga shot, you’ll have around 95% protection starting from 30 days and lasting up to a year after vaccination.

 

Are there side effects of Qdenga?

Side effects are usually mild, like soreness where the shot was given, a slight fever, or a headache. These don’t last long and are common with many vaccines.

 

Why is Qdenga important in fighting dengue?

Qdenga is a big step in controlling dengue, especially in places where the disease is very common. It can help reduce the number of people getting sick and the severity of the illness.

 

Where is Dengue most common?

Southeast Asia: Countries like Thailand, Vietnam, the Philippines, Malaysia, and Indonesia are known for high rates of dengue.

South and Central America: Brazil, Mexico, Colombia, and other nations in these regions often report significant dengue cases.

The Caribbean: Dengue is common in many Caribbean islands.

Parts of Africa: Certain African countries, especially those in the Sub-Saharan region, experience dengue outbreaks.

Indian Subcontinent: India, Pakistan, Bangladesh and Sri Lanka have reported dengue cases.

Pacific Islands: Some islands in the Pacific, including Fiji and Samoa, also see dengue infections.

Northern Australia: Particularly in Queensland, dengue cases occur, though they are less common than in other regions mentioned.
