Warning signs of more severe dengue virus include the typical signs and symptoms in additional to some or all of the following: severe abdominal pain restlessness and fatigue persistent vomiting which may include blood shortness of breath nose bleeds and bleeding gums.
A small number of people who experience these symptoms will go on to have severe dengue which can include: severe bleeding extremely low blood pressure caused by blood loss shock coma death. Dengue virus in Australia Cases of dengue virus occur in northern Queensland from time to time when travellers who have been infected overseas return and introduce the virus to the local mosquito population.
How dengue virus is spread Dengue virus is not transmitted spread from person to person. Avoid mosquito bites and avoid dengue virus in commonly affected areas Protect yourself against mosquito bites to avoid dengue virus and other mosquito-borne diseases in dengue-affected areas. Suggestions include: Wear socks, long pants and long-sleeved shirts.
Loose fitting clothing makes it harder for mosquitoes to bite you through your clothes. Reapply regularly and make sure you follow directions for safe use on the label. For kids, it can be safer to spray insect repellent on their clothes rather than their skin. Apply insect repellent first thing in the morning because dengue mosquitoes bite during the day, both outdoors and inside homes and buildings. Direct spread of dengue from one person to another does not occur.
Aedes aegypti mosquitoes are not found naturally in New York State. Dengue fever symptoms include sudden onset of a fever that may last from 2 to 7 days with intense headache, joint and muscle pain, and a rash. Mild bleeding of the nose or gums may occur. The hemorrhagic form of dengue fever is more severe and symptoms may include loss of appetite, persistent vomiting, high fever, headache, difficulty breathing, and abdominal pain. This may lead to shock and circulatory failure.
Dengue fever may occur from 3 to 14 days after being bitten by an infected mosquito, but usually within 4 to 7 days. Symptoms and travel history can cause a health care provider to suspect dengue fever. Laboratory tests will be needed to confirm diagnosis by seeing if the virus or antibodies against the virus are present in the person's blood.
There is no specific treatment available. Intravenous fluids and oxygen therapy are often used for patients who become very ill.
Access to proper medical care reduces the likelihood that the disease will become more serious. Infection with one of the four strains of dengue virus usually produces immunity to that strain but does not provide protection against the other strains. There are not yet any approved vaccines to prevent infection with dengue virus.
Since cases of dengue appearing in New York are imported, preventive measures are advised for travelers going to affected areas to minimize exposure to mosquitoes. The most effective protective measures are those that avoid mosquito bites. The warning signs usually begin the first day or two after your fever goes away, and may include:.
Severe dengue fever is a life-threatening medical emergency. Seek immediate medical attention if you've recently visited an area in which dengue fever is known to occur, you have had a fever and you develop any of the warning signs. Warning signs include severe stomach pain, vomiting, difficulty breathing, or blood in your nose, gums, vomit or stools. If you've been traveling recently and develop a fever and mild symptoms of dengue fever, call your doctor.
Dengue fever is caused by any one of four types of dengue viruses. You can't get dengue fever from being around an infected person. Instead, dengue fever is spread through mosquito bites. The two types of mosquitoes that most often spread the dengue viruses are common both in and around human lodgings. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito.
Then, when the infected mosquito bites another person, the virus enters that person's bloodstream and causes an infection. After you've recovered from dengue fever, you have long-term immunity to the type of virus that infected you — but not to the other three dengue fever virus types.
This means you can be infected again in the future by one of the other three virus types. Your risk of developing severe dengue fever increases if you get dengue fever a second, third or fourth time. Severe dengue fever can cause internal bleeding and organ damage.
Blood pressure can drop to dangerous levels, causing shock. In some cases, severe dengue fever can lead to death. Women who get dengue fever during pregnancy may be able to spread the virus to the baby during childbirth.
Additionally, babies of women who get dengue fever during pregnancy have a higher risk of pre-term birth, low birth weight or fetal distress. In areas of the world where dengue fever is common, one dengue fever vaccine Dengvaxia is approved for people ages 9 to 45 who have already had dengue fever at least once.
The vaccine is given in three doses over the course of 12 months. The vaccine is approved only for people who have a documented history of dengue fever or who have had a blood test that shows previous infection with one of the dengue viruses — called seropositivity. In people who have not had dengue fever in the past seronegative , receiving the vaccine appears to increase the risk of severe dengue fever and hospitalization due to dengue fever in the future.
