Dengue ( डेङ्गी | /ˈdɛŋɡi/ ) is a debilitating viral disease of the tropics, which is transmitted by mosquitoes, that causes sudden fever and acute pains in the joints. A mosquito-borne tropical disease which is caused by DENV (Dengue Virus) is known as dengue fever.
People from more than 110 nations are found to have been infected by the dengue virus in the past, and more than forty-two percent (42%) of the world’s current population, which is more than 3 billion people, live in areas facing higher chances of dengue. Dengue is a leading cause of illness in these areas, and each year, around 410 million people get infected with dengue, and, among them, about 110 million get sick from infection and 25,000 die from severe dengue. The greatest risk of dengue occurs in the Indian subcontinent (Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka), Southeast Asia, Southern China, Taiwan, The Pacific Islands, The Caribbean (except Cuba and the Cayman Islands), Mexico, Africa and Central and South America (except Chile, Paraguay, and Argentina).
It takes four to fifteen days for the symptoms to appear once infected. Typical symptoms of the fever are: high fever, headache, muscle pains, pains in the joint, vomiting, and a kind of a skin rash. The recovery process may be as long as a week. Infected individuals who do not take care of this problem may give rise to dengue hemorrhagic fever which is severe and more dangerous. The consequences of this new fever can be bleeding, decrease in the levels of blood platelets, leakage of blood plasma, or dengue shock syndrome that may cause the occurrence of dangerously low blood pressure.
Which Mosquito Species Cause Dengue?
Several species of female mosquitoes, mainly Aedes aegypti, spread dengue. Aedes Aegypti is often known as the yellow fever mosquito that can spread dengue fever, Mayaro, Zika fever, chikungunya and yellow fever viruses. This species of mosquitoes have white markings on their legs and a marking in the form of a lyre on the upper surface of their thorax. Researchers have found out that this mosquito species came from Africa and have their habitats in tropical, subtropical and temperate regions of the present-day world.
There are only a few ways to diagnose the dengue fever or the dengue hemorrhagic fever.
NAATs can help diagnose individuals with diseases related to the dengue virus in case of suspicion. These tests are the laboratory diagnosis methods which are mostly preferred by medical professionals.
Medical professionals need to perform NAATs on serum specimens collected within 7 days after the onset of the symptoms.
An important tool to diagnose the disease, IgM antibody testing may assist professionals identify additional infections.
Molecular as well as serologic diagnostic testing needs to be performed in cases where the infections are suspected to have occurred in areas where other possible cross-reactive flaviviruses circulate.
This method of detecting IgG by enzyme-linked immunosorbent assay (ELISA) in a single serum sample is not as useful as the previous methods because researchers have found out that an individual can detect it forever after the infection by the dengue virus.
Since this disease is spread through the bite of an infected mosquito, the best way to prevent dengue fever is by not letting mosquitoes bite you. You can also buy insect repellants, such as Odomos Non-sticky Mosquito Repellant Cream, from our website.
Another thing you can do is get vaccinated. If you are interested in getting vaccinated with Dengvaxia which is licensed and available in only a few countries for people aged between 9 and 45 years. However, the World Health Organization suggests that the vaccine should be given only to individuals who have been infected by the dengue virus in the past. Talk to one of our healthcare providers and find out if you can get vaccinated in Nepal.
The most convenient ways to protect yourself from this possibly dangerous dengue virus are to use mosquito repellent seven while you are indoors; to wear long-sleeved shirts and long pants tucked into your socks when you are outdoors; to use air conditioning when indoors if possible; to make sure to secure your window and door screens; and, to check if the windows and doors do not have holes. Most people in developing and underdeveloped nations prefer to use mosquito nets as their places are not screened or air-conditioned.
Adults are advised to dress their children in clothes that cover their arms and legs completely. They should also cover strollers and baby carriers that come with mosquito netting. Similarly, when using an insect repellent on the young children, adults should always follow the instructions given on the labels, and if the children are younger than 3 years old, they should not use products containing oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD). However, the repellant should not be applied to a child’s hands, eyes, mouth, any cuts, or skin if they have any kind of irritation. Parents must apply the insect repellant onto their hands first before applying it to a child’s face.
Any medical professional who has some understanding of this disease will recommend you to purchase Environmental Protection Agency (EPA)-registered repellents along with one of the active ingredients mentioned below:
EPA-registered insect repellants can also be used by pregnant and breastfeeding women when they are used as directed by a medical expert. You can talk to an expert at 24Seven by registering with us here.
As there are no specific medicinal products to treat the infection caused by the dengue virus, you are advised to use pain killers with acetaminophen and not consume any medicinal items containing aspirin which may worsen the bleeding. In addition, infected individuals should not forget to rest, consume as much fluids as possible, and take consultation about your condition with a doctor. If the start feeling severely ill even after the fever goes down, you must go to a hospital which can check your body for complications.
