Abstract
Dengue fever (break-bone fever) is a viral disease transmitted by Aedes mosquitoes. It is caused by the Dengue virus, which is a single positive-stranded RNA virus belonging to the Flaviviridae family. Dengue fever is prevalent in tropical and subtropical areas and is a significant public health concern in many countries, including`g Nigeria. The disease is characterized by symptoms such as high fever, headache, body aches, nausea, vomiting, swollen glands, and rash. In severe cases, dengue fever can lead to complications such as bleeding, organ impairment, and dengue shock syndrome. Diagnosing dengue fever can be challenging, especially in areas where it is endemic. In endemic locations, diagnosis is often made clinically based on the patient's reported symptoms and a physical examination. Tourniquet testing, which involves applying a blood pressure cuff and counting any petechial hemorrhages, can help in the diagnosis. Laboratory methods, including full blood count, cell culture, nucleic acid identification (PCR), and serology, can be used to confirm the diagnosis. Preventing dengue fever involves controlling the mosquito vector and protecting oneself from mosquito bites. Measures such as eliminating mosquito breeding sites, using insect repellents, wearing protective clothing, and using bed nets can help prevent mosquito bites. Vaccination against dengue is also available, with the Dengvaxia vaccine being used in some countries. There is no specific antiviral treatment for dengue fever. Management focuses on supportive care, maintaining a healthy fluid balance, and relieving symptoms such as fever and pain. Severe cases may require hospitalization and intensive medical care. In Nigeria, dengue fever is often misdiagnosed or overlooked due to similarities with other febrile illnesses like malaria. This can lead to underreporting and inadequate management of dengue cases. Increasing awareness among healthcare professionals and the general population is crucial for early detection and appropriate management of dengue fever in Nigeria. In conclusion dengue fever is a viral disease transmitted by mosquitoes, primarily Aedes species. It is a significant global health concern, including in Nigeria. Early diagnosis, prevention measures, and supportive care are essential in managing dengue fever and reducing its impact on public health. This review is aimed at discussing the current issues of Dengue fever with focus on Nigeria.
