DENGUE FEVER - AWARENESS OF DENGUE

 

DENGUE FEVER - AWARENESS OF DENGUE

1-INTRODUCTION

A) What is Dengue Fever?

Dengue fever is an irresistible infection sent by mosquito and brought about by any of the four related dengue infections.

It is additionally called "break bone fever" since it might cause serious joint and muscle torment. Dengue is communicated by female Aedes mosquito. Since no immunization is accessible, anticipation is the best cure.

B) History

Dengue is one of the numerous viral sicknesses communicated by the mosquito. The sickness generally break out I dangerous scourges that spread with stunning rate as seen in 2011 in Lahore. The illness has impacted all warm regions of the planet like Pakistan, India, Sri Lanka, Bangladesh, Central Africa, Central America and China. It is a sickness of monkeys sent to them by woodland staying mosquitoes.

Episodes in human populace probably started when a portion of these mosquitoes got the infection from monkeys and cleared a path to human towns where they began rearing.

Subsequently tainted people conveyed the infection to urban communities where Aedes took over as the vector.

C) Occurrence and Geographical Distribution:

Dengue was geologically limited until the center of twentieth century. It was somewhat a minor infection. During the second universal conflict, Aedes mosquitoes (eggs) were moved all throughout the planet with freight and thought to have assumed a critical part in the spread of infection. It was first appropriately archived in 1950's during plagues in the Philippines and Thailand. It is tracked down relentlessly in neighborhood populaces (endemic) in excess of 100 nations in Asia, America and Africa. World Health Organization (WHO) has assessed that 50 to 100 million diseases happen each year.

2-SYMPTOMS:

After tainted mosquito's chomp, hatching time of 4 - 7 days is needed before the side effects show up in the patient. The indications of various sorts of dengue fever are as per the following:

a) Types of Dengue Fever

These include:

1-Asymptomatic or Undifferentiated fever.

2-Dengue Fever

3-Dengue Haemorrhagic Fever (DHF)

4-Dengue Shock Syndrome (DSS)

1-Asymptomatic or Undifferentiated fever.

This is a sort of fever which addresses influenza like side effects with gentle fever.

2-Dengue Fever

The temperature transcends 1020F with serious migraine, spinal pain, torment at the rear of the eyes and joints, with queasiness and spewing.

3-Dengue Haemorrhagic Fever (DHF)

It happens in under 5% of the patients. This is joined by broad spillage of plasma. Not very many cases show draining from nose, gums and rashes on the skin. There might be a decline in pulse, feeble heartbeat and cool limits. There is a quick decline in white platelets (WBCs) and platelets. Now and again this might prompt DSS.

4-Dengue Shock Syndrome (DSS)

At the point when a Dengue patient encounters shock, he has dengue shock condition. Both DHF and DSS patients need severe clinic observing and concentrated consideration.

3-DIAGNOSIS:

Complete blood count (CBC) showing absolute number of RBCs, WBCs and platelets per unit volume of blood is the fundamental symptomatic test.

4-DENGUE VIRUS:

Dengue fever is brought about by one of the four sorts of dengue infection, DEN-1, DEN-2, DEN-3 and DEN-4 which are called its serotypes.

a) In Human Creatures:

It enters the skin of the human through spit of contaminated female Aedes mosquito, when it chomps for a blood feast. It duplicates in the body cells, for example, WBCs and manifestations show up following 4 - 7 days.

b) In Mosquito:

At the point when a female Aedes nibbles a patient, it procures infection. It increases in the body of the mosquito and is in this way delivered in the spit. The infection doesn't bring about any sickness in mosquitoes

5-DENGUE VECTOR:

The transporter of the dengue infection is Aedes mosquito. It is dark in shading (up to 10 mm in size) with white spots on the body and legs and has sparkly wings. Both the male and female mosquito feed on plant nectar, however no one but female can nibble human as its mouth parts are intended for this reason and bear style for sucking blood. The female mosquito needs to suck blood to lay eggs.

a) Life Cycle of Aedes Mosquito and its Comparison With Anopheles:

An examination between the various phases of the existence pattern of two types of mosquitoes is given beneath:

(i) Eggs:

Female Aedes lays eggs, in the wake of having a blood supper, in clean standing water. These eggs are dark in shading, elongated in shape and are laid independently. Their number reaches from 50 - 300, contingent on the stickiness and temperature. Eggs of female Anopheles mosquito are oval in shape, laid separately on the outer layer of water.

(ii) Larvae:

In Aedes, Larvae emerge from the eggs after a brooding of 2 - 7 days, which hang upward with siphon or breathing cylinder contacting water surface. They move effectively through and through and feed on vegetation and hatchlings of different creepy crawlies.

In Anopheles, the hatchlings rest corresponding to the outer layer of water, they don't have siphon or breathing cylinder, however have pores or spiracles on body for relaxing.

(iii) Pupa:

In Aedes, the hatchlings takes care of, develops quickly and projects (sheds) its skin multiple times and turns into a pupa. The pupa is comma molded comprising of an enormous adjusted foremost part (head and chest and an extended thin, bended, sectioned midsection, it doesn't take care of however can swim effectively.

Following a couple of days, external covering of the pupa parts in the mid dorsal line and the youthful mosquito arises, which subsequent to drying its wings takes off. Grown-ups ordinarily rest with body equal, however in some cases at a point to the resting surface. It as a rule nibbles toward the beginning of the day and before nightfall.

The grown-up Anopheles is tanish in shading without any stripes. It sits pretty much at a point to the surface. It is typically dynamic around evening time. Aedes conveys the dengue infection while Anopheles is a transporter of Plasmodium which causes jungle fever.

(b) Breeding Sites:

Aedes mosquitoes breed in clean water which might collect in regular or counterfeit compartments. The regular holders incorporate tree openings, bamboo internodes and leaves while counterfeit compartments incorporate disposed of containers, food bundling, frozen yogurt cups, dishes and so forth Harmed machines, disposed of tires, scrap vehicles, boats, utensils and devices, toys, pails, room coolers, painting plate, openings in broken wall, rooftops, floors, water stockpiling tanks, barrels, containers, skillet and cans are great reproducing places. In short we ought to lessen each chance of assortment of water.

(c) Transmission of Dengue:

Aedes mosquito itself doesn't can fly over significant distance. The fast ascent in exchange and travel across the world brought about flare-ups of dengue pandemics in regions where it was already missing (however the vector Aedes is available), and can likewise be sent through blood bonding and organ relocate.

6-PREVENTIVE MEASURES AND CONTROL:

For the anticipation of this sickness it is vital that the public mindfulness crusades among masses ought to be dispatched, notwithstanding different prudent steps taken at different levels.

a) At Personal Level

Individuals can forestall mosquito's chomps by wearing garments that completely cover the skin.

Use mosquito nets which are splashed with insect spray

Apply mosquito anti-agents

b) At Household Level

Controlled splashing (Considering symptoms) of all aspects of the house, under the furnishings, in the background, dull corners, stores, and eliminating all garbage things will dispose of the resting/rearing shelters.

c) At Community Level:

The environmental factors of the house ought to be kept clean. No trash or strong waste ought to be permitted to gather at any spot. Splashing of bug spray/larvicide ought to be polished.

Plagues can be forestalled or constrained by all around facilitated local area endeavors by expanding the mindfulness about dengue fever. Individuals ought to figure out how to perceive and separate between three distinct phases of dengue fever (DF, DHF and DSS). They ought to likewise have the option to separate between the Anopheles and Aedes mosquitoes, their reproducing destinations and methods of transmission of dengue infection. They ought to know about the control measures.

Mindfulness message can be given to the majority through print and electronic media for example radio, TV, paper and so forth Educators ought to likewise assume their positive part by illuminating their understudies pretty much all elements associated with the spread of the illness, and about its control. The understudies can spread this message to their home and family and furthermore to different individuals from their territory. Khatibs of mosques should spread this message among people in general through their lessons. Market councils and associations can likewise be useful in such manner.

d) Biological Control

The utilization of synthetics these days is being debilitate in view of its perils to the climate. The organic control is being leaned toward due to its innocuous nature. Consequently, as of now the utilization of regular foes and hunters for the control of this illness is basic.

Many birds go after mosquitoes.

·         Divider reptiles (geckos), bouncing bugs obliterate various mosquitoes.

·         Certain fish are regular hunter of mosquito hatchlings in lakes.

·         Hatchlings of different bugs likewise feed on hatchlings of mosquito.

7-PATIENT MANAGEMENT

·         As in the event of other viral sickness complete rest ought to be encouraged to the patient.

·         Family specialists ought to be counseled, however there is no particular drug accessible.

·         At first paracetamol ought to be taken to control fever. Medications like ibuprofen and brufen ought to be completely stayed away from.

·         Patients should take a lot of liquid to stay away from drying out.

·         Any individual who is having fever for at least 3 days ought to counsel a specialist.

·         On the off chance that the patient feel more awful (like regurgitating, extreme stomach torment or draining the person ought to be quickly moved to the clinic for treatment.

8-GOVERNMENT'S EFFORTS TO CONTROL DENGUE

Administration of the Punjab reacted expeditiously to the pandemic. An exceptionally dynamic multidirectional crusade was begun to monitor the sickness. Educators, understudies, specialists, paramedical staff, a few Government offices and public delegates headed by the Chief Minister Punjab, participated in this mission.
