In the month of August alone, national capital Delhi has seen 477 cases against 11 cases in 2013 and 142 cases in 2014 bringing chill into the people. Here’s a take on Dengue’s reach and implications, if it is not too late for you.
Dengue, caused by Aedes mosquito, has four types – DEN-1, DEN-2, DEN-3 and DEN-4 — and even if a person gets lifetime immunity from one particular serotype, there is always a strong possibility to get the disease again from other kinds of serotypes.
Aedes mosquito has eight different types of species. Of these, Aedes aegypti and Aedes albopictus are the two most significant ones that are responsible for causing dengue, chikungunya, and many other types of diseases. WHO explained that an aedes mosquito obtains the dengue virus after it sucks in the blood of an already infected person, and spreads the disease when it bites another person with the virus inside its body.
During their earlier stages, the species breeds on fresh and clean water-contained environments close to the dwellings of humans, which have a clean urban atmosphere. This shows the difficulty if fighting these mosquito species.
Only female mosquitoes bite human beings because the blood is a necessity for them to mature eggs. These eggs have the capability to live for months and can be hatched until a five-time increase by the aedes female mosquitoes. Only a few aedes species can lay up to twelve eggs and cause an enormous dengue plague.
The Aedes aegypti has the ability to make a huge flight, ranging as high as 400 meters. Besides this, they spend most of their lifetime roaming inside and in the surroundings of human dwellings, which makes it very easy for them to spread the dengue virus and cause an outburst of the disease.
Symptoms of Dengue
Normal dengue fever starts with a flu that lasts for a couple of days or even a week. The incubation period goes on from 4-10 days, post bite from an infected mosquito and body temperature rises up to 104 degree Fahrenheit.
Other symptoms are headache, vomiting, nausea, swollen glands, joint pains and rashes.
When the condition of the patient deteriorates too much and he/she develops acute dengue then symptoms like severe abdominal pain, bleeding from gums, vomiting blood, fast breathing, weakness, and constant vomiting.
Useful ways to fight dengue
- Aedes aedypti breeds in stored waters like unchanged water inside flower vase, stagnant water in buckets, wet shower floors and toilet tanks. These situations favor the mosquitoes to lay eggs, therefore, always keep stagnant waters out of your house.
- Wear full-sleeved robes during the day as well as evening because although aedes mosquitoes can spread the disease all year long, they mainly bite at dawn and dusk time.
- Apply mosquito repellants on your robes, especially if they are made of thin fabrics because it’s easy for mosquitoes to bite through them.
- Spray mosquito repellants in and around your house as well to stay extra protective.
With new reports, saying that Delhi saw 253 fresh new cases of dengue, causing the total number of confirmed cases rising to 530, these new useful ways to stay away from dengue might come handy.
