Do we have a vaccine for dengue?

Dengue Vaccine Across the Globe Dengue vaccine Dengvaxia (r) is approved and marketed in several countries for persons aged 9 to 45. The World Health Organization advises that the vaccination be administered only to patients who have had a verified past dengue virus infection. The vaccine has been linked to severe neurological disorders including paralysis and death. Its safety for children under 9 has not been established.

What is the best way to prevent dengue? There is no single method that will protect you from getting sick or spreading the disease, but taking simple precautions can help reduce your risk of being infected. The most effective methods include avoiding mosquito bites by using insect repellent, wearing clothing that covers skin, and installing screening on windows and doors. See our article on how to protect yourself from mosquitoes for more information.

There is no treatment for dengue fever itself, but there are medications used to manage pain and inflammation, treat high temperatures, and sleep through symptoms if necessary. A pharmacist will be able to advise you on which products are best for you based on various factors such as your tolerance to different medications and any other conditions you may have.

Does the age of someone affect how they respond to dengue vaccines? No, age is not considered when deciding whether or not to give a dengue vaccine.

Which injection is used for dengue fever?

Dengvaxia, a dengue fever vaccine, was licensed by the US Food and Drug Administration in May 2019 for use in dengue-endemic areas. It is the first vaccine approved to prevent dengue infection or disease.

Injection of the vaccine into your arm should be done in a doctor's office by someone who knows how to inject vaccines into children. The vaccine is given as two shots at least one month apart.

Children who have not been vaccinated against dengue should not receive the vaccine. Anyone who has had severe allergies to proteins found in vaccines should not receive the vaccine. Children who have not received three doses of the vaccine may not be fully protected against all four strains of dengue virus that are prevalent in their area.

Children who have received three doses of the vaccine may still get sick with dengue after they go out in public places where there are lots of people who aren't vaccinated. In this case, they would need a tetanus shot too.

The vaccine is made from the strain of virus that caused the recent epidemic in Brazil. It is hoped that this vaccine will reduce the number of cases of dengue fever in people who were not previously infected with the virus.

Is there a vaccine for dengue fever in Canada?

In Canada, there is presently no licensed vaccination for dengue fever. Travelers to dengue-prone areas should take precautions against mosquito bites, whether outside or inside buildings. These include using insect repellent, wearing long-sleeved shirts and pants, and installing screening on windows and doors. Dengue vaccines are under development but not yet available for use in humans.

For now, the best defense against dengue is awareness of the symptoms and prevention of mosquito bites. If you do come into contact with a mosquito that has bitten an infected person, take appropriate action by removing its body part where it attaches itself (usually by squeezing hard), and call your doctor.

Dengue is a viral disease spread by mosquitoes. Symptoms include fever, muscle pain, headache, nausea, vomiting, diarrhea, eyesight problems, and skin rash. Most people recover from dengue within a week to 10 days, but some may experience severe complications such as plasma leakage leading to severe hemorrhaging or death. There is no cure for dengue infection at this time.

Anyone who will be traveling to countries where dengue is found should learn about the risk factors and take measures to prevent being bitten by mosquitoes.

Dengue is found in more than 100 countries around the world.

Can dengue be transmitted through blood transfusion?

By exposure to tainted blood, a laboratory, or a healthcare environment Dengue can be transmitted by blood transfusion, organ transplantation, or a needle stick injury in rare cases. The virus is not destroyed by standard screening procedures used by most blood banks so it is possible for infected donors' blood to transmit the disease to recipients.

Blood products are screened for viruses including Dengue before they are released by laboratories that comply with standards set by the American Red Cross and other blood agencies. These processes attempt to remove any potential contaminants that could lead to transmission of diseases such as Dengue fever after transfusion. In addition, donors are asked about symptoms of infection every time they give blood and none have reported recent travel to areas where Dengue is found.

However, because there is no cure for Dengue and because patients with severe forms of the disease may need multiple blood transfusions, it is possible that undiagnosed donors could transmit the virus. As with any viral illness, individuals who have not been previously exposed to Dengue should be monitored for signs and symptoms of infection for at least 24 hours after exposure to determine if post-exposure prophylaxis is needed. If no symptoms develop, regular blood tests can be done to see if the person has antibodies against Dengue virus.

Is hospitalization necessary for dengue?

The majority of dengue patients may be treated in hospital outpatient departments, with only the most severe cases requiring hospitalization. The World Health Organization, or WHO, has issued a recommendation on the symptoms that should lead to hospitalization in patients. They state that patients should be hospitalized if they have plasma leakage (increased volume of fluid outside the blood vessel, usually due to increased permeability of capillaries) or severe hemorrhage.

Hospitalization is also recommended for patients who develop warning signs of plasma leakage or severe bleeding. These include: rapid decrease in platelet count, persistent vomiting, restlessness, easy bruising or bleeding from any site, red eyes caused by low blood pressure, and decreased urine output.

Patients do not need to be hospitalized for simple dengue fever. Those who are well enough to be discharged can go home, but will need to stay away from work and school until it's clear they are no longer at risk of developing serious complications.

In some cases, patients may require supplemental oxygen, intravenous fluids, and blood products such as transfusions or clotting factors if they experience significant bleeding. Patients with these needs may be given special care in a specialized unit known as an intensive care unit or ICU.

Which areas of the world are the most vulnerable to dengue?

Dengue fever has been a worldwide concern since the 1960s. Many prominent tourist sites in the Caribbean (including Puerto Rico), Central and South America, Southeast Asia, and the Pacific Islands are affected by the illness. In addition, there is evidence that it is becoming established in parts of Africa for the first time.

Dengue affects more than 100 million people per year, and estimates indicate that there are now about 50 million cases per year worldwide. The disease is found from the tropics to the temperate zones around the world, but it is especially prevalent in tropical regions where the climate allows for its reproduction within the vector (the mosquito). There are four types of dengue virus: dengue 1, 2, 3, and 4. They all belong to the genus Dengue virus and family Flaviviridae. Symptoms include high fever, headache, muscle pain, nausea, vomiting, diarrhea, chills, cough, and skin rash. Some patients may need hospitalization if their conditions worsen.

In order to prevent the spread of dengue, health officials recommend reducing exposure to the virus by avoiding places with large numbers of mosquitoes (such as backyard pools) and using insecticide treated clothing and tents at home and while traveling in endemic areas. As part of global efforts to control the spread of dengue, countries report annual incidences of the disease to the World Health Organization.
