Dengue fever is a viral illness transmitted by the Aedes mosquito. It is a leading cause of illness and death in tropical and subtropical regions, with an estimated 400 million infections occurring annually worldwide. The disease is characterized by the sudden onset of high fever, severe headache, joint and muscle pain, and rash. In severe cases, dengue fever can progress to dengue hemorrhagic fever, which can lead to hospitalization and death.
There is currently no specific treatment or vaccine for dengue fever, and the only way to prevent the disease is to control the mosquito population and prevent mosquito bites. Research into dengue fever has therefore focused on identifying the mechanisms of the disease, developing methods for its prevention and control, and searching for potential treatments and vaccines.
One area of research in dengue fever has focused on understanding the immune response to the virus. The immune system plays a crucial role in determining the severity of the disease, and understanding how the immune system responds to dengue infection could lead to the development of treatments to improve immune function and reduce the severity of the disease.
Another area of research has focused on the development of vaccines for dengue fever. Several vaccines have been developed and are currently in various stages of clinical trials, including one that has been licensed for use in several countries. These vaccines have the potential to significantly reduce the burden of dengue fever, particularly in areas with high transmission rates.
In addition to these efforts, research is also being conducted on methods to control the mosquito population and prevent the spread of dengue fever. This includes the use of insecticides, mosquito nets, and other methods to reduce the number of mosquitoes in an area.
Overall, dengue fever research has made significant progress in recent years, and the potential for the development of treatments and vaccines offers hope for those affected by the disease. However, much work remains to be done to fully understand the disease and to effectively control and prevent its transmission.
Dengue Fever and Climate Change
Less than half of the respondents 43. Clinical Infectious Diseases, 2016. The virus may also be detected by testing for a virus-produced protein, called NS1. IgG antibody levels take longer to develop and remains in the body for years. Respiratory Medicine, vol 7. Submit your questions or research papers. The overall alarming increase in case numbers over the last two decades is partly explained by a change in national practices to record and report dengue to the Ministries of Health, and to the WHO.
Dengue fever and its epidemiological characteristics: a study from Eastern India
. This is an open access article distributed under the terms of the Data Availability: All relevant data are within the manuscript and its Funding: The author s received no specific funding for this work. Hitchens, Dengue: Its history, epidemiology, mechanism of transmission, etiology, clinical manifestations, immunity and prevention. The American region alone reported 3. The Transportation and LandUse program, led by Professor Eric Goldwyn, examines transit-infrastructure projects, land-use policies, and complementary data sets to understand how public agencies build, manage, and pay for capital projects, like subway expansions, bicycle lanes, and high speed rail. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. Mosquitoes are also vectors transmitters of several viruses that can …show more content… It is one of the most rapidly rising mosquito transmitted infections in the world and has been identified as a re-emerging disease in Southeast Asia.
Knowledge, awareness and preventive practices of dengue outbreak in Bangladesh: A countrywide study
So, an emphasis should be provided on health education programme especially on dengue disease to increase community knowledge and awareness towards Aedes mosquitoes and DF prevention countrywide. Emergence of dengue virus 4 genotype II in Guangzhou, China, 1010: Survey and molecular epidemiology of one community outbreak. The correlation matrix demonstrated the existing relationships between the pairs of variables. But it also represents government recognition of the burden, and therefore the pertinence to report dengue disease burden. Care was taken to confirm the accuracy and uniformity of the data. Toma, Cold acclimation and overwintering of female Aedes albopictus in Roma. The respondents were given an explanation of the objectives and benefits of the study.
In addition, the increased risk of developing hemorrhagic disease or dengue shock when reinfected with the virus is consistent with the possibility that some serotypes produce more severe disease. Subsequent infections secondary infection by other serotypes increase the risk of developing severe dengue. Other species within the Aedes genus can also act as vectors, but their contribution is secondary to Aedes aegypti. PLoS ONE 16 6 : e0252852. Center for Disease Control and Prevention. A five-year study in five Asian countries investigated the efficacy of measures designed to bring this disease under control. Methods: Total 82 patients 63 male, 19 female admitted with diagnosis of dengue fever were analysed in details from clinical features… Expand.
[PDF] A Study on Clinical Presentation of Dengue Fever in Children
There are currently four main serotypes of dengue: DENV-1, DENV-2, DENV-3, and DENV-4. The first infection with the virus will confer life-long immunity against the offending serotype, but not against the other three Weaver and Vasilakis, 2009. The last section covered 8 questions on knowledge and awareness regarding dengue prevention. There is an ongoing need to adhere to other disease preventive measures such as well-executed and sustained vector control. Incidence of dengue illness was 1. It affects the tropical and subtropical regions of the world.
In 2012, an outbreak of dengue on the Madeira islands of Portugal resulted in over 2000 cases and imported cases were detected in mainland Portugal and 10 other countries in Europe. Several additional dengue vaccine candidates are under evaluation. Vaccination against dengue The first dengue vaccine, Dengvaxia® CYD-TDV developed by Sanofi Pasteur was licensed in December 2015 and has now been approved by regulatory authorities in ~20 countries. . For severe dengue, medical care by physicians and nurses experienced with the effects and progression of the disease can save lives — decreasing mortality rates to less than 1% in majority of the countries. Depending on the time of patient presentation, the application of different diagnostic methods may be more or less appropriate. Proceedings of the National Academy of Sciences of the United States of America, 2013.
In 2020, dengue affected several countries, with reports of increases in the numbers of cases in Bangladesh, Brazil, Cook Islands, Ecuador, India, Indonesia, Maldives, Mauritania, Mayotte Fr , Nepal, Singapore, Sri Lanka, Sudan, Thailand, Timor-Leste and Yemen. Hemorrhagic fever will affect over half a million people each year, contributing to 25,000 yearly dengue-related deaths reviewed by Jing et al. It is caused by four serotypes of dengue virus. The genetic differences between the four main serotypes are significant for several reasons. However, they require specialised equipment and training for staff to perform these tests. First, variables of interest were assessed using univariate analysis.
American Journal of Tropical Medicine and Hygiene, 2006. Manna , +2 authors S. It requires management by medical professionals. Severe dengue has a higher risk of death when not managed appropriately. American Journal of Tropical Medicine and Hygiene, 1987. Knowledge, attitude and preventive practice KAP towards dengue fever in different regions of Bangladesh. IgM antibodies are detectable ~1 week after infection and remain detectable for about 3 months.
Distribution and outbreaks Before 1970, only 9 countries had experienced severe dengue epidemics. Maternal transmission The primary mode of transmission of DENV between humans involves mosquito vectors. For Dhaka region, a total of 210 samples were collected, 100 from Dhaka metropolitan area and remaining 110 from outside of Dhaka metropolitan area i. 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. Early detection of disease progression associated with severe dengue, and access to proper medical care lowers fatality rates of severe dengue to below 1%. WHO World Health Organization.
