Dengue is transmitted by the mosquito bite called “Aedes”.

It is well distributed around the world.

Dengue fever in mild cases usually causes flu-like illness, but symptoms range from mild to severe. They typically start within a week after the mosquito bite and typically last 3 to 10 days.
In its severe form, dengue may cause dengue shock syndrome (DSS) and dengue hemorrhagic fever (DHF). These may be life-threatening and need hospitalization.
There are currently no vaccines. The best method is to avoid mosquitos bites.

Signs & Symptoms:

In mild cases, it may present with flu and mild fever, headache, gastro-intestinal upset. These symptoms settle in a few days time. In severe cases, fever is high with generalized body aches, nausea and vomiting.
Fatal complications include Dengue Haemorrhagic fever. Manifestations may be a hypovolaemic shock, bleeding from multiple sites, severe GI symptoms. Such patients must be admitted and treated aggressively.

 

Diagnosis

As it is a viral illness, there is no specific treatment. If the disease is mild, the mainstay of treatment is correcting hydration and pain killers. Non-steroidal drugs must be avoided due to the risk of bleeding.

In severe cases, hospitalization with iv fluid replacement or blood transfusion is required along with other conservative measures.
