An Overview of Dengue Fever

Abstract

Context: Dengue fever has been reported in 129 countries worldwide, including 100 countries in the Mediterranean region, South America, and Southeast Asia. It results in approximately 40,000 deaths each year, and there have been significant outbreaks of dengue fever in these areas in recent years. Approximately 50% of the global population is presently susceptible to acquiring the dengue virus, which is classified as an emerging and re-emerging ailment that is likely to impact several nations in the foreseeable future. Evidence Acquisition: Despite the significant harm inflicted upon human health and the economic conditions of countries in recent years, dengue continues to be classified as a neglected disease, without the requisite attention and concerted efforts by countries to effectively manage it. Any actions taken in this domain are inherently constrained. Consequently, due to the significance of dengue fever, this study aims to comprehensively examine this matter. Results: The disease used to be effectively managed in regions like the countries of the American continent and Singapore, but it has made a resurgence. Between 2008 and 2010, the number of cases in the regions of America, Southeast Asia, and the Western Pacific rose from 0.2 million to 2.2 million. These reports exclusively consist of officially documented sick cases. Multiple outbreaks have been documented in Asia, encompassing countries such as China, Pakistan, Taiwan, and Malaysia, as well as in South America, including Brazil and Mexico. Dengue fever cases have been documented in several Middle Eastern nations, including Yemen, Saudi Arabia, and southern Iran. Local transmission of the disease has begun in Europe, with France and Croatia reporting cases of local transmission. Annually, a minimum of 500,000 individuals experience serious illnesses requiring hospitalization. Approximately 2.5% of individuals who contract the condition die from it. Every year, numerous severe cases of dengue fever are documented, resulting in at least 20,000 deaths. Conclusion: Dengue fever is a complex systemic disease. Assessing the complete range of the disease burden of dengue fever will be crucial to properly comprehend the serious medical and economic repercussions it has on patients and the general public.
