DENGUE FEVER- SYMPTOMS, CAUSES AND TREATMENT
Dengue (DENG-gey) fever is a mosquito-borne disease that appears in tropical and semitropical areas of the world. Mild dengue causes a high fever and flu-like indications. So, the major form of it is also known as dengue hemorrhagic fever can become the reason for bleeding, a sudden drop in blood pressure (shock), and death.
Millions of instances of dengue infection take place worldwide each year. It is very common in Southeast Asia, the western Pacific islands, Latin America and Africa. This disease has been expanding to new areas, including local outbreaks in Europe and southern parts of the United States.
Investigators are working on its vaccines. There are many areas in which dengue is common. The best way to prevent infection is to avoid being bitten by mosquitoes and to take measures to lessen the mosquito populations.
Many people have no indications or symptoms of dengue infection. After that symptoms occur then people think that it is the flu. The symptoms begin after 4 to 10 days. 104 F (40 C) is the highest temperature for this, and the following are the signs and symptoms of dengue:
- Muscle, bone or joint pain
- Pain behind the eyes
- Swollen glands
Many people get better within a week or so. In some cases, symptoms become worst and can become dangerous. This is severe dengue, dengue hemorrhagic fever, or dengue shock syndrome.
Extreme dengue happens when your blood vessels are damaged. The number of your platelets also drops in it. This can go ahead to shock, internal bleeding, organ failure, and even death.
The symptoms, which typically begin within the first day or two of your fever subsiding, may include:
- Severe stomach pain
- Persistent vomiting
- Bleeding from your gums or nose
- Blood in your urine, stools or vomit
- Bleeding under the skin, which might look like bruising
- Difficult or rapid breathing
- Irritability or restlessness
Dengue fever is caused by any one of four kinds of dengue viruses. You can’t acquire dengue fever from being around a sick person. Instead of it, it is scattered through mosquito bites.
The two types of mosquitoes are common. When a mosquito bites a person contaminated with a dengue virus, the virus moves into the mosquito. If that infected mosquito bites another person, the virus then enters that person’s blood and becomes the cause of an infection.
After you’ve been cured of dengue fever, you have lasting immunity to the type of virus that infected you. It means that you can be infected again in the future by the other three virus types. Your chance of improving severe dengue fever increases if you have fever for the second, third or fourth time.
You have a risk to get dengue if
- You are living or travelling in a tropical area
- You have dengue fever in a past
In those areas where dengue is common, the dengue fever vaccine is appropriate for people ages 9 to 45 who have already faced dengue in past. There are three doses of vaccine given in 12 months. The vaccine is certified only for people who have a recorded history of dengue fever or had a blood test. The people who do not have had dengue fever in the past (seronegative), getting the vaccine appears to boost the risk of severe dengue .
Dengvaxia is not offered for travelers or for people who live in the continental United States. But in 2019, the U.S. Food and Drug Administration certified the vaccine for people ages 9 to 16 who faced dengue in the past and who live in the U.S. territories of American Samoa, Guam, Puerto Rico, and the U.S.
