DENGA is an infectious disease caused by a virus that can affect humans. If you have the virus, it can cause severe illnesses. In this article, you’ll learn more about the symptoms, how to prevent it, and the treatment options. It’s important to know what to expect before you get infected.
Symptoms
If you suspect you have the dengue virus, it is vital that you seek medical attention as soon as possible. Although there is currently no cure for the disease, the symptoms can be treated and managed with supportive care. These treatments include maintaining adequate blood volume and reducing fever. You may also want to take acetaminophen for aches and fever. However, be sure not to use NSAIDS because these medications may increase the risk of bleeding.
People of all ages are at risk of contracting dengue fever. The disease is typically contracted from a mosquito bite. The Aedes mosquito, which also spreads Zika and chikungunya, is a major vector for dengue infection. People who have been infected with this virus often exhibit symptoms of a flu-like illness. The symptoms are not life-threatening, but they can be debilitating. In most cases, patients with the disease will require bed rest and fluids.
In rare cases, a person may develop dengue shock syndrome. In this case, the person develops low blood pressure and a weak pulse. They may also experience cold skin and restlessness. If the symptoms persist, they should seek medical attention immediately. In severe cases, dengue may even lead to organ failure and death.
The best way to prevent catching dengue is to avoid mosquito bites. You can do this by wearing protective clothing to minimize exposure. In addition, apply permethrin to your clothing and shoes and cover your sleeping area with mosquito netting. If you are unable to stay indoors, it is also recommended to use mosquito repellent that contains DEET.
In most cases, laboratory tests can detect the presence of dengue fever. However, they cannot accurately predict the progression of the disease and its severity. In addition, a diagnosis of dengue fever requires a detailed review of a patient’s past health history, recent travels, and vaccination history. While there is no cure for dengue fever, symptomatic treatment and supportive care can help reduce the mortality rate to less than one percent.
If you suspect you have the dengue virus, contact your local emergency room or call NHS 111. Tell your doctor that you’ve been traveling in tropical regions and experienced dengue fever symptoms. Although there is no specific cure for the virus, you can relieve your symptoms by staying hydrated and taking painkillers. Avoid taking NSAIDs during the course of dengue, because these drugs can make bleeding worse.
Transmission
DENV (dengue virus) infection is spread from human to human by mosquitoes. Transmission is facilitated by contact with a symptomatic person, pre-symptomatic person, or asymptomatic person. The virus can be transmitted up to two days before or after symptoms are visible.
Transmission is most common through mosquitoes, especially Aedes aegypti. These mosquitoes breed in man-made and natural containers. They can infect humans, especially young children. Female mosquitoes can infect multiple individuals at once, so there is a high risk of clusters of infected individuals.
The simplest and most reliable way to diagnose DENGA infection is to test for the virus in a sample of the person’s blood. The virus is detectable by analyzing a specific protein, called NS1. Commercially produced rapid diagnostic tests can detect NS1 levels and provide a result within 20 minutes. They don’t require specialized equipment or staff. Nevertheless, it is best to consult a medical professional if you suspect that you have the disease.
Prevention
The most effective prevention of dengue fever is to avoid being bitten by a mosquito. You can do this by keeping away from the area where mosquitoes breed and lay their eggs. You should also empty water-holding containers. If you have to sleep in an area without screens, you should use mosquito nets to prevent mosquito bites.
The vector for dengue infection is the Aedes aegypti mosquito, which is common in the region. This mosquito carries the dengue virus and feeds almost exclusively on humans. It is found in rural areas as well as urban areas. In the Americas, Aedes aegyptian mosquitoes are widely distributed, and their population has increased in the past few decades.
If you develop dengue fever, the first step in treatment is to contact your healthcare provider. The treatment for this illness usually involves intravenous fluids and electrolytes, and blood transfusion in severe cases. If you experience any flu-like symptoms, stay indoors and avoid mosquito bites to help prevent the disease from spreading.
Although the majority of cases are asymptomatic, severe dengue can cause respiratory distress and organ damage. It can be fatal in rare cases. Because there is no effective vaccine or specific treatment for dengue infection, prevention is the only way to avoid contracting the disease. The symptoms will last from four to ten days after being bitten by an infected mosquito. Most sufferers recover completely in a week or two. However, in more severe cases, the disease may lead to serious complications such as dengue hemorrhagic fever or dengue shock syndrome.
The Aedes aegypti mosquito is the main vector for dengue. It also transmits chikungunya and Zika fever viruses. Infected mosquitoes bite other people, and the virus is spread through their bite. Although it is not contagious like the flu, pregnant women are at high risk for dengue infection.
While the fatality rate is below one percent, early detection is crucial to preventing the disease. Proper prevention and vector control measures are the most important steps in preventing the spread of denga.
