What is dengue?
We explain what dengue is and how is the development of this mosquito. In addition, what are the symptoms of the disease it transmits.
What is dengue?
Dengue is an acute viral disease that affects thousands of people of any age . The most vulnerable population are children and the elderly. The agent that transmits this disease through its bite is the mosquito, whose technical name is “Aedes aegypti”, recognizable mainly by its long legs with black and white horizontal stripes, also has dark wings and filiform antennae.
Dengue is a disease that mainly concentrates in urban areas . It can be produced in two ways (with different severity each):
- Dengue Fever It is a flu-like illness, which can cause death but this rarely happens.
- Dengue hemorrhagic fever. It causes serious bleeding that can lead to death, it is very serious in the case of affecting children.
How does the dengue mosquito develop?
The dengue-transmitting mosquito proliferates by reproducing in shallow water tanks , for this reason it is that government information programs are carried out on ways to prevent their proliferation. In the stagnant water the mosquito deposits its eggs and larvae. The larvae are deposited vertically in the water, evolves through four different larval stages that can last several months.
One of the main measures to combat it is to eliminate all containers that contain water and are outdoors . The mosquito prefers dark sites and is usually concentrated inside homes.
The females of this specimen are stubborn mincers during daylight hours. They are able to spawn 100 or 300 eggs after two or three days of being fed with blood. Their eggs have a high drying capacity, they also strongly resist low temperatures, once the temperatures are warmer and humid, the eggs hydrate and hatch, the larvae come out.
The females bite because they have the need to feed so that the eggs in this way mature, they are obligate hematophagous. The schedule in which they are dangerously active, and their bite is much more frequent, is in the morning and late afternoon. They usually bite in the lower limbs .
What are the symptoms of dengue?
The main symptoms of the disease are: fever, high headache, nausea, vomiting, severe stomach pain, muscle and joint pain, loss of taste and appetite, measles rash on the chest and lower extremities, and continued nosebleeds, buccal or gingival
In the natural environment the most fertile water deposits of these insects are the wells, puddles and water that remains in the hollows of the trunks or stones; on the other hand in rural areas it is common to find that these mosquitoes proliferate in stagnant waters in pots, drinking fountains, buckets, puddles, vases, abandoned wells, etc. For this last point, it is indicated that programs aimed at preventing the proliferation of the mosquito indicate that a key to achieving this is to prevent water from stagnating.
