Dengue Fever: Symptoms, Causes, Precautions & Treatment

Dengue is a mosquito-borne disease common in tropical and subtropical countries around the world. This is because the climatic conditions of these countries are very favourable for the development and survival of mosquitoes that carry the dengue virus. 

For example, in India, dengue cases peak after the monsoon. In the 1950s, severe Dengue was first reported in the Philippines and Thailand but has now spread to most of Asia and Latin America. People from other countries also develop this craze if they travel to tropical areas. As a result, dengue cases have increased drastically around the world in recent decades. 

What are the causes of dengue fever? 

Dengue is mainly caused by the dengue virus, transmitted in the human body by an infectious bite of Aedes aegypti, a female mosquito of the species. 

Aedes aegypti is native to Africa but is now found in tropical regions worldwide. Experts explain the four serotypes of the dengue virus; DEN 1, DEN 2, DEN 3 and DEN 4. 

Mosquitoes are diurnal breeders, which means they are more active after sunrise and before sunset, so special attention is needed during the period—this paragraph. 

Mosquitoes cause mild and severe dengue fever. However, only 1 out of 20 people develop severe Dengue, but doctors advise against missing any chance of a diagnosis. Newborns, pregnant women, and people who have had dengue fever in the past are at increased risk for severe Dengue. 

Although Dengue can occur in rural and urban areas, studies have shown that it is more common in rural areas. That is why the governments of the affected countries have now started educating their rural populations about the disease. 

What are the symptoms of Dengue? 

It's a flu-like illness that affects everyone; infants, children and adults. Symptoms usually appear three to 14 days after infection of the body. People often have two types of symptoms; gentle and strict. Sometimes mild symptoms are mistaken for viral fever and can be life-threatening if the tests are not done on time. People are advised to consult health specialists and doctors if they develop a fever and other related symptoms.
