Being more vulnerable to Dengue

Friday, 30/09/2016

In order to understand people vulnerability to this disease, it is important to understand the disease itself. It is a flu-like disease, which occurs due to the bite of female Aedes mosquito infected with a dengue virus. It is not directly spread from one human to another but can be transferred from one human to mosquito when it bites. Chikungunya is rarely fatal. Symptoms are generally self-limiting and last for 2–13 days. The virus remains in the human system for 5-7 days and mosquitoes feeding on an infected person during this period can also become infected. Chikungunya shares some clinical signs with dengue and can be misdiagnosed in areas where dengue is common. Because dengue is more common

1. Symptoms

• Sudden high fever is one of the major symptoms of dengue.
• Severe headaches
• There can be pain behind the eyes
• Severe joint and muscle pain
• Fatigue
• Nausea
• Vomiting
• Skin rash, which appears two to five days after the onset of fever
• Mild bleeding (such a nose bleed, bleeding gums, or easy bruising)

2. Places affected

The disease is transmitted by the Aedes albopictus, which can withstand cooler temperatures and is found in tropics and sub-tropical regions. Following are the places which are affected by this disease, therefore making people residing her more vulnerable to this diseases.
• The Indian subcontinent
• Southeast Asia
• Southern China
• Taiwan
• The Pacific Islands
• The Caribbean (except Cuba and the Cayman Islands)
• Mexico
• Africa
• Central and South America (except Chile, Paraguay, and Argentina)

In the United States most cases occur with people who contracted the infection while traveling abroad.

3. Vulnerability

One of the main factors leading to people getting dengue is lack of awareness and negligence. Most people are unaware of symptoms and take it lightly for common viral fever. One should not ignore these symptoms are it might develop into some serious problem like dengue hemorrhagic fever, a rare complication characterised by high fever, damage to lymph and blood vessels, bleeding from the nose and gums, enlargement of the liver, and failure of the circulatory system.

Sometimes symptoms may progress to massive bleeding, shock, and death which is often known as dengue shock syndrome (DSS). People who have weakened immune systems as well as those who are dealing with second or subsequent dengue infection are more vulnerable to be at greater risk for developing dengue hemorrhagic fever.

Moreover, they keep bad and unhygienic conditions around themselves which leads to breeding of such mosquitoes.
They should follow certain measures to protect themselves from dengue:
1. Use mosquito repellents and wear clothes which cover all exposed body-parts.
2. Keep mosquito repellents.
3. Spray-repellents in all corners of the room
4. Use medicated mosquito nets.
5. Keep the surroundings clean and drain stagnant water.
6. Spray medicines in open areas to avoid breeding of such mosquitoes.
7. When affected by it, keep yourself as hydrated as possible.
8. If in doubt, seek immediate medical attention.
9. International travelling should keep in mind the place and conditions while travelling and take necessary repellents with them.

As this painful disease spreads, half a million patients are hospitalized each year now which is not good. People should increase awareness and do their share with government in reducing the statistics of this disease.
