In recent years, the spread of dengue fever due to lack of hygiene and climatic conditions has been rampant in developing countries.

As dengue burden rises in the country, the likelihood of more people becoming severely ill grows. Read on and know more about the reasons for dengue and the simple precautionary methods to prevent it.
What causes dengue?
Four types of dengue viruses are responsible for causing this hemorrhagic disease in man. Mosquitoes that thrive in and near human lodgings carry the viruses to people through their pricking bites. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. The infected insect then bites another person and passes the pathogen to the person’s bloodstream.
When you've recovered from dengue fever, your body develops immunity to the type of virus that struck you. It doesn’t mean that you are safe from the other three dengue pathogens. The risk of developing severe dengue fever, also known as dengue hemorrhagic fever, actually increases if you're infected a second, third or fourth time.
Know your symptoms

When affected by dengue, the temperature may rise to 104F and the patient is likely to suffer from headaches, swollen joints, nausea and muscle pain. Usually, the fever subsides in a week. In some cases, the symptoms can worsen and it can be life-threatening.
