What Are The Signs And Symptoms Of An Asthma Attack – Dengue fever is a disease spread through the bite of mosquitoes infected with the dengue virus. Symptoms are often flu-like but can progress to severe dengue (dengue fever), a dangerous condition. A second exposure increases the risk of serious symptoms. You can get the vaccine if you have had dengue once.
If you live in or visit an area with dengue, seek medical attention immediately if warning signs of severe dengue develop. These include abdominal pain, blood in your vomit or ulcers, bloody stools or nose, frequent vomiting or extreme tiredness or restlessness.
What Are The Signs And Symptoms Of An Asthma Attack
Dengue fever is a disease caused by the bite of a mosquito that carries one of the four types of dengue virus (DENV). The virus is often found in tropical and subtropical regions, including Central and South America, Africa, parts of Asia and the Pacific Islands.
Adhd In Women: Common Signs And Symptoms
Dengue is not transmitted from person to person except from a pregnant woman to her child. Symptoms are usually mild with your first infection, but if you are infected with another type of DENV, the risk of severe complications increases.
Dengue is most common in Central and South America, Africa, parts of Asia and the Pacific Islands. A few parts of the United States still have dengue. Those who live or travel to these areas – more than half the world’s population – are most at risk. Children and the elderly are most at risk of serious illness.
Research estimates that nearly 400 million people are infected with dengue every year, but most (about 80%) have no symptoms.
Yes, you can get a vaccine against the dengue virus after being infected. Because there are at least four strains of the virus (DENV), it is very complicated.
What Is Myelopathy? (signs, Symptoms, Risk Factors & Causes)
Your immune system has tools it can use to identify infections and fight them better. When your body is fighting bugs, you look in your toolbox to see what antidotes you have that can destroy the threat.
Antibodies are specific to attack each wound in your body, as they describe as the key to the lock. Viruses attack their own targets and destroy your immune system. Once your body learns how to fight this bug, you won’t get sick again.
Once you’ve had one of the four types of DENV, you shouldn’t be able to get it again. But the virus for this species is not compatible with other species. So if you later get infected with another type of DENV, you can use this deficiency to trick your immune system (antibody-dependent immunity).
Other reactions may be caused by antibodies from the original strain that entered your cells, but – for reasons that are not understood – did not destroy them. Then it’s in your cells without the cells knowing it’s harmful. This makes it easier for you to spread the virus and cause a more severe illness.
Signs And Symptoms Of Ptsd
Most dengue infections do not cause symptoms. If you have symptoms, a high fever (104°F/40°C) is common, including:
Symptoms of dengue fever begin to appear four to 10 days after a mosquito bite and may last three to seven days. About 1 in 20 people who get dengue have severe dengue after their initial symptoms start to fade.
Severe dengue is a symptom of dangerous dengue. Warning signs of severe dengue usually appear 24 to 48 hours after your fever goes away.
Acute dengue is a potentially fatal medical emergency. If you have dengue or live in an area where dengue is endemic, go to the nearest ER if you have any of the following symptoms:
Mesothelioma Signs And Symptoms
Dengue fever is one of the four dengue viruses. When a mosquito that carries the dengue virus bites you, the virus can enter your bloodstream and reproduce on its own. The virus itself and your immune system’s response can make you sick.
The bacteria can destroy the part of your blood that forms and damage your blood vessels. This, along with certain chemicals created by your immune system, can cause your blood to leak out of your vessels and cause internal bleeding. It causes severe dengue symptoms.
Dengue is spread by the Aedes mosquito, which also carries viruses such as Zika and chikungunya. Mosquitoes bite a person with dengue, who then bites another person, causing them to become infected.
Dengue fever is not directly contagious from one person to another like the flu. The only way to get dengue from someone else is if the fetus is infected. If you are pregnant and have dengue, you can pass it to your baby during pregnancy or delivery.
Pneumonia: Causes, Symptoms, Diagnosis & Treatment
Dengue fever is diagnosed by a blood test. Your doctor will take a blood sample and send it to a laboratory to look for signs of the dengue virus. It can also identify the four types of features you have. Your provider may use blood tests to look for other infections that cause similar symptoms.
There is no medicine to treat dengue fever. Your doctor will give you recommendations on how to manage your symptoms and how and when you should go to the ER.
Controlling your symptoms is the only way to treat dengue fever. Follow your doctor’s recommendations, which may include:
The dengue vaccine (Dengvaxia™) is only recommended if you have had dengue. You can reduce the risk of severe dengue (dengue hemorrhagic fever) if you are infected with another dengue virus in the future.
Warning Signs Of A Heart Attack
Vaccination is not recommended if you have not had dengue before. Because one exposure to dengue makes you more likely to get sick if you get another version of the virus (antibody-dependent immunity), getting vaccinated before getting dengue for the first time can increase your chances of getting infected. severe dengue fever. Your doctor will do a blood test to check for signs of previous dengue infection to confirm that you had dengue before you received the vaccine.
Vaccination is not for everyone. For example, travelers from the United States are not yet eligible. Talk to your doctor to find out if you are eligible for the dengue vaccine.
Most cases of dengue fever have no or mild symptoms, but sometimes you may have a more severe illness that requires immediate treatment.
The first symptoms of dengue are three to seven days. Most people start to get better after this, but some have life-threatening conditions that require hospital treatment.
Help To Identify The Symptoms Of Depression
Most people recover from dengue fever without any long-term complications. If you have symptoms of dengue fever, there is a 1 in 20 chance that it will worsen into severe dengue. If you have a severe case of dengue and are treated immediately at a hospital or health center, you have a more than 99% chance of recovery.
If you are pregnant and have dengue fever, it can cause miscarriage, low birth weight or premature birth. It is important to take precautions to prevent dengue during pregnancy to protect yourself and your unborn child.
Yes. Because there are at least four subtypes (types) of the dengue virus, you may get dengue more than once.
Usually you will be immune from the first infection and cannot get it again. But you can get sick with one of the other three types after that. In fact, you can get very sick if you get dengue more than once.

If you’ve had dengue in the past, you’re more likely to get seriously ill if you get another version of the virus in the future. Try to get vaccinated and take precautions to protect yourself from mosquito bites, especially if you live in an area with dengue.
If you live in an area with dengue or have recently visited an area with dengue, contact your doctor if you have symptoms of dengue. They will give you advice on how to take care of yourself and when to seek additional care.
If you have warning signs of severe dengue, even if your initial symptoms have improved, go to the emergency room immediately. Severe grief can become a real fear of life.
Never mind. Although they kill only a small proportion of those infected, malaria is more deadly than dengue worldwide.
Sexually Transmitted Infections (stis): Sexually Transmitted Diseases (stds)
Of the 400 million people worldwide who contract dengue every year, about 40,000 die from it (0.01%). Of the estimated 271 million people worldwide infected with malaria each year, approximately 627,000 die from it (about 0.3%).
It is important to remember that all diseases can be more deadly in some parts of the world than others. Children in Africa are at risk of dying from malaria, while people living in Asia are most affected by dengue.
Millions of people are infected with dengue every year. Although most cases are mild or asymptomatic, the thought of dengue can be frightening. The word “dengue” may come from the word “evil spirit” which was thought to cause it
