Aedes mosquitoes predominantly cause the transmission of Dengue virus. These mosquitoes generally dwell in the areas with and elevation below 1,000 m (3,300 ft.) and having latitudes within 35° South and 35° North. Early morning and evening hours are two typical timings at which Aedes mosquitoes are more likely to bite. However, they can possibly bite at other day timings, and hence, a spread of infection may occur. The reports of World Health Organization (WHO) (2012) disclose that around 390 million sufferers from dengue disease do exist around the globe and 96 million necessitate medical treatment. About 500,000 victims of the severest category of dengue hemorrhagic fever require hospitalization every year. About 40% of the population of the world live in dengue-prevalent regions.

Dengue is the main disease triggered by dengue virus that is placed in the host and known internationally as one of the most significant vector-borne diseases by the female Aedes aegypti mosquito. As a fast SPR-based approach, anti-dengue identification of the virus in serum samples was proposed (Jahanshahi et al., 2014). They reported that they could rapidly and conveniently use their method, defined as 10 min identification of the im-munoglobulin M-based dengue diagnostic test. As ligands on SPR receptors, they used various dengue virus serotypes. They found 83-93 percent sensitivity and required to indicate SPR angle difference for increasing dengue serotype in specimens to be 100 percent specificity to 1 ml.

The mosquito vector spreads the dengue virus, with the majority of infections occurring in Latin America and Asia [65]. Dengue virus has four serotypes that can cause anything from mild dengue fever to severe dengue shock syndrome in humans [66]. The main diagnostic procedures are still nucleic acid or protein/serological based due to the small sizes of dengue viruses.

Dengue is a viral infection caused by the dengue virus, which is transmitted to humans through the bite of an infected Aedes mosquito. Symptoms of dengue include high fever, severe headache, joint and muscle pain, nausea and vomiting, and rash. In severe cases, dengue can lead to dengue hemorrhagic fever, which can cause bleeding, low platelet count, and even death. Prevention of dengue is mainly focused on controlling the population of Aedes mosquitoes, which can be done by eliminating their breeding sites, such as standing water in containers. Personal protective measures include using mosquito repellent and wearing long-sleeved clothing. There is no specific treatment for dengue, and treatment mainly involves relieving symptoms and providing supportive care. In severe cases, hospitalization may be necessary. Dengue is a significant public health problem in many tropical and subtropical countries, including India, Indonesia, Brazil, and Thailand. As dengue is a mosquito-borne disease, it can be difficult to control, and outbreaks can occur suddenly. In conclusion, dengue is a serious viral infection that can cause severe illness and death. It is transmitted by Aedes mosquitoes and can be prevented by controlling the population of mosquitoes and personal protective measures. There is no specific treatment for dengue, and treatment mainly involves relieving symptoms and providing supportive care.

There are knowledge gaps in the epidemiology and clinical practice with regard to dengue worldwide. After decades, vector control programs have failed, especially in low- and middle-income areas such as Asia, Latin America, and the Pacific countries. Similar challenges that existed decades ago, including the elimination of vector breeding containers, environmental management, larvicide abatement of water storage receptacles, and use of chemical fogging, still exist. Measures must be taken together and over a long period of time to produce the expected effects (Katzelnick et al. 2017). In Brazil and developing countries, once the epidemic is controlled, government officials abandon control practices, and actions are discontinued (Pereira et al. 2021). With regard to clinical practice in cases of dengue, although a decrease in mortality rates has been observed worldwide in recent decades, severe dengue remains a harmful disease and there is a gap between developed and developing countries. Shock, hemorrhage, and major organ failure can occur with severe dengue virus infection; however, the frequency of these manifestations varies, and the relative contribution of pre-existing anti-dengue virus antibodies, virus characteristics, and host factors including age and comorbidities are not well understood (Katzelnick et al. 2017; Sharp et al. 2022)

Clinical progression of a typical dengue infection can be divided into three stages. Stage 1, classic dengue fever, or simply dengue fever (DF) characterized by several symptoms including headache, eye-pain, myalgia, arthralgia, some manifestations of hemorrhages, rash, anorexia, nausea and diminishing leucocyte counts. Some patients previously infected with the dengue virus can develop stage 2, dengue hemorrhagic fever (DHF) that may present extreme abdominal pain, constant vomiting, hypothermia (cold clammy skin), hemorrhages intensified by increased vascular permeability, narrow pulse pressure, rapid and weak pulse as well as experiencing irritability and confusion. Complications resulting from such symptoms lead to stage 3, dengue shock syndrome (DSS) which can be detected by a rapid and weak pulse, narrow pulse pressure (≤20 mmHg), anxiety and clammy skin. Some DF/DHF patients’ condition can suddenly deteriorate and falling into DSS, with a very clear risk of fatality (Günter et al. 2009; Castillo-Macías et al. 2017; McFee 2018).
