Dengue, also known as break bone fever, is a vector-borne disease that is spread by mosquitoes. As per data collected by the National Vector Borne Disease Control Programme (NVBDCP) and National Health Profile 2018, the number of dengue cases in India has grown from 60,000 in 2009 to 1,88,401 in 2017, which is a 300% increase. Moreover, 2017 saw the highest number of deaths in the country due to dengue in a decade. Doctors are of the opinion that the months of July and November are the most dangerous for the spread of dengue, however, owing to climate change, it is also becoming a year-round threat in the country.

Read on to know all about the dengue disease, its causes, symptoms, treatment and prevention.

How does Dengue spread?

Dengue spreads through the bite of an Aedes mosquito that is carrying the dengue virus. So, the mosquito acts as an agent in transmitting the dengue disease. These mosquitos belong to a species called Aedes Aegypti and you can identify them by the white stripes on their bodies and legs. Dengue is not contagious and hence does not spread via direct contact between two people

Symptoms of Dengue Fever

According to doctors, many infected individuals don’t show any signs of dengue. However, some show mild dengue symptoms at the start that worsen with time. These signs and symptoms of dengue surface after 3 to 7 days, or sometimes even 15 days after a virus-infected mosquito bite.

The common dengue fever symptoms are as follows.

  • In the first phase, you may get a fever of up to 104 degrees Fahrenheit coupled with low heart rate and low blood pressure. Your eyes may redden and you may also develop rashes on your face. These signs and symptoms of dengue last for up to 4 days. Thereafter, your body temperature may drop and you are likely to feel better for a day or so.

  • In the second phase, your body temperature is likely to increase again and you may also start sweating. These signs of dengue usually last for a day or so.

  • In the third phase, your body temperature is likely to rise rapidly and the rashes may resurface all over your body, except your face.

Apart from these dengue symptoms, you should also watch out for:

  • Nausea

  • Loss of appetite

  • Swelling in the hands and soles of feet

  • Chills

  • Backache

  • Joint and muscle pain

  • Inflammation in the groin

Know All about Dengue Treatment

Dengue recovery takes a week or less, unless your condition is severe, in which case the disease can be life-threatening. Therefore, if you suspect having dengue, see a doctor immediately to avail dengue treatment, as self-medicating may cause further complications.

While suffering from dengue, vomiting and high fever can result in dehydration. To avoid decreased urination, dry mouth or lips, lethargy or confusion and cold or clammy extremities, doctors suggest increasing your fluid intake. For more severe cases, blood transfusion may be required due to a drop in the platelet count.

Dengue Fever Prevention - How to Avoid Dengue?

As the Aedes mosquito feeds during the day, with early morning and before dusk being peak periods, you should take special precautions during these hours.

Here are certain dengue fever prevention measures that you can implement.

  • Prevent water from stagnating and dispose waste properly. Store water in a clean, covered utensil.

  • Use mosquito repellents after reading the warning on the label, or rely on natural alternatives such as marigold, lemongrass, and other plants.

  • Use mosquito netting while sleeping if required.

  • Avoid wearing dark-coloured clothes as they attract mosquitoes. Instead, wear light-coloured, full-sleeved clothes.
