Dengue Mosquito-borne viral disease that occurs in the tropics and subtropics.
Anyone infected with the virus a second time has a significantly higher risk of developing serious illnesses.
Symptoms include a high fever, headache, rash, and muscle and joint pain. In severe cases, there is severe bleeding and shock, which can be life-threatening.
Treatment includes fluids and pain relievers. Severe cases require hospital treatment.
The prognosis for dengue is generally reasonable. The disease’s worst symptoms usually last for a week or two, and most patients make a complete retrieval within a few weeks. Typical dengue fever is fatal in less than 1% of cases; However, hemorrhagic fever is malignant in 2.5% of cases
What is Dengue Fever, and How it Spreads?
The dengue virus transmitted by some Aedes mosquitoes and is considered one of the world’s greatest threats as the world’s urban landscape expands.
In addition to increasing desirable habitats for container-breeding species, the virus has four strains (multiple serotypes), making it difficult for healthcare professionals to handle.
The chikungunya virus has symptoms similar to fever and confers immunity to future chikungunya infections in bitten people. Unfortunately, with multiple strains of , a person is more likely to be hospitalized or die if they are infected with more than one serotype.
People who already infected or have weakened immune systems should take even more stringent precautions.
Requirement for Dengue Virus Disease
Dengue virus infection a “routine” reportable disease and must be reported in writing by doctors and pathology departments within five days of diagnosis.
Dengue Fever Throughout History
The earliest record of a Dengue-like illness comes from the Jin Dynasty (265-420 AD) in China. There is also some evidence that diseases similar to fever erupted in the 17th century. However, three epidemics that appeared at the end of the 18th century marked the arrival of the disease now known as dengue.
Two of these outbreaks involved a condition similar in terms of symptoms and course to , and both occurred in 1779, one in Cairo and the other in Batavia (now Jakarta) in the Indies. Dutch (now Indonesia). Dutch doctor. David Byron.
Identification of Dengue Virus Disease
Dengue fever classically presents itself as an acute febrile illness with a sudden onset. It is highly debilitating with the turmoil that lasts 3 to 5 days, myalgia (especially back pain), arthralgia (hence “bone fracture”), retroorbital pain, anorexia, gastric pain, Intestinal disorders, intestinal rashes, and increased vascular permeability.
There a high subclinical rate of mild illness in children compared to adults and a low mortality rate compared to DHF in children and adults.
Recovery from infection with one virus serotype results in immunity but does not protect against disease with other serotypes.
Dengue Fever Hemorrhagic Fever
Dengue fever hemorrhagic fever is a severe complication of infection with the dengue virus. It occurs mainly in children and characterized by sudden onset of fever, hemorrhagic phenomena, and thrombocytopenia.
Its most simple form can lead to shock , which has a high mortality rate. The death rate from DHF without acquired immunodeficiency syndrome (DSS) is usually between 1 and 5 percent.
Dengue hemorrhagic death believed to caused by an immune surge when a person with antibodies to subsequently infected with a different serotype of the virus from a previous infection.
