Can you get dengue again after suffering from it once?

What is dengue fever?

Dengue is a virus-based infection majorly predominant in the tropical regions of the world. The female Aedes mosquito is the vector that transmits dengue causing virus cells from infected people to healthy people through blood-sucking bites. The virus then transfers from the vector and enters the host to rapidly reproduce dengue causing virus. Dengue is commonly classified in 4 different serotypes, which are: DENV 1, DENV2, DENV3, and DENV4. DENV 3 and 4 are the most occurring forms of the virus.

How do you get dengue?

Insect bites: the virus that causes dengue can be transmitted by the bite of infected female mosquitoes of the species Aedes aegypti and, to a lesser extent, the species Aedes albopictus

Mother-to-child: possible transmission from mother to child during pregnancy or childbirth

Rare cases of transmission via blood products, organ donation, and transfusions

How common is dengue fever?

Research estimates that nearly 400 million people get infected with dengue each year, but most (about 80%) have no symptoms.

How to protect yourself from dengue

The Spread of Dengue fever can be reduces by targeting the mosquitoes that transmit the disease:
Prevent mosquitoes from accessing egg-laying habitats
Dispose of waste properly and remove artificial man-made habitats
Cover, empty, and clean domestic water storage containers regularly
Apply insecticides to outdoor water storage containers
Use personal household protection such as window screens, long-sleeved clothes, insecticide-treated materials, coils
Apply insecticides during outbreaks as an emergency vector-control measure

Dengue fever – Symptoms

Symptoms

Severe dengue

First, the fever typically falls to 99.5 to 100.4°F (37.5 to 38°C). Severe symptoms may then appear 24–48 hours Trusted Source later, or around 3–7 days Trusted Source after the person starts to feel unwell. They include:

Dengue Fever Complications:

When should we do a dengue test?

Dengue fever is a viral infection spread by mosquitoes, which easily spreads from person to person. A dengue fever test is conducted to detect the infection of the dengue virus. It is mostly used for people who have symptoms of illness and/or have recently traveled to an infected area. It is recommended to have a dengue test if you have –

Prevention and control

If you know you have dengue, avoid getting further mosquito bites during the first week of illness. Virus may be circulating in the blood during this time, and therefore you may transmit the virus to new uninfected mosquitoes, who may in turn infect other people.
The proximity of mosquito vector breeding sites to human habitation is a significant risk factor for dengue. At present, the main method to control or prevent the transmission of dengue virus is to combat the mosquito vectors. This is achieved through:

Prevention of mosquito breeding:

Personal protection from mosquito bites:

Using of personal household protection measures, such as window screens, repellents, coils and vaporizers. These measures must be observed during the day both inside and outside of the home (e.g.: at work/school) because the primary mosquito vectors bites throughout the day;

Wearing clothing that minimises skin exposure to mosquitoes is advised;

Community engagement:

Educating the community on the risks of mosquito-borne diseases;

Engaging with the community to improve participation and mobilization for sustained vector control;

Active mosquito and virus surveillance:

Active monitoring and surveillance of vector abundance and species composition should be carried out to determine effectiveness of control interventions;

Prospectively monitor prevalence of virus in the mosquito population, with active screening of sentinel mosquito collections;

Vector surveillance can be combined with clinical and environment surveillance.

In addition, there is ongoing research amongst many groups of international collaborators in search of novel tools and innovative strategies that will contribute in global efforts to interrupt transmission of dengue. The integration of vector management approaches is encouraged by WHO to achieve sustainable, effective locally adapted vector control interventions.

Epidemiology:

It is the fastest spreading mosquito-borne viral disease globally, affecting greater than 100 million humans annually. Dengue also causes 20 to 25,000 deaths, primarily in children, and is found in more than 100 countries. Epidemics occur annually in the Americas, Asia, Africa, and Australia. Two transmission cycles maintain the dengue virus: 1) mosquitoes carry the virus from a non-human primate to a non-human primate, and 2) mosquitoes carry the virus from human to human. The human-mosquito cycle occurs primarily in urban environments. Whether the virus transmits from human to mosquito depends on the viral load of the mosquito’s blood meal.

Dengue Treatment (Mosquito Management)

24×7 Pest Management Services technician will prepare a Dengue Management Treatment plan that’s right for you. Our plan begins with a thorough property inspection.
A combination of treatments to break the mosquito’s life cycle, preventing larvae from becoming breeding, biting, and potentially disease-carrying adults. Frequency & Chemical to be used depends upon the level of infestation; Regular treatment is required to control Mosquitoes.
