Dengue fever, a viral illness transmitted primarily by Aedes mosquitoes, is a growing global health concern. With an estimated 390 million infections annually, it poses a significant threat to human populations in tropical and subtropical regions. This arbovirus, belonging to the Flaviviridae family, is characterised by sudden onset of fever, severe joint and muscle pain, rash, and other flu-like symptoms.

Dengue fever is primarily transmitted to humans through the bite of infected Aedes mosquitoes, most commonly the Aedes aegypti species. The process of catching dengue fever begins when a female Aedes mosquito, already infected with the dengue virus, bites an individual. These mosquitoes are typically active during the day, with peak activity in the early morning and late afternoon. When an infected mosquito feeds on a person's blood, it injects the dengue virus into the bloodstream. Once inside the human body, the virus begins to replicate and spread. The individual bitten by the infected mosquito may not immediately experience symptoms, as there is an incubation period that typically ranges from 4 to 10 days. During this time, the virus multiplies within the body. As the infection progresses, symptoms of dengue fever may start to manifest. These symptoms can include high fever, severe headaches, joint and muscle pain, rashes, and in some cases, bleeding from the gums or nose. It's important to note that dengue fever cannot be directly transmitted from one person to another. Instead, the virus relies on the mosquito vector to continue its transmission cycle. Preventing dengue fever involves a multi-faceted approach, including reducing mosquito breeding sites, using insect repellents, wearing protective clothing, and implementing public health measures to control mosquito populations. In regions where dengue is endemic, these preventative measures are crucial to minimizing the risk of contracting this potentially debilitating disease.
Individuals residing in or traveling to regions where dengue fever is endemic are at risk of contracting the disease. This includes tropical and subtropical areas of the world, such as Southeast Asia, the Pacific Islands, the Caribbean, and parts of Central and South America, where the Aedes mosquito vectors thrive. Dengue fever does not discriminate based on age or gender, making anyone within these areas susceptible. In particular, those who do not have prior exposure to the virus or have not been vaccinated are at a higher risk of infection. Moreover, travelers from non-endemic regions who visit dengue-prone areas can also be at risk, as they lack pre-existing immunity. Pregnant women and individuals with certain medical conditions may face a higher risk of severe dengue complications, so they should take extra precautions to avoid mosquito bites and seek medical attention promptly if they develop symptoms. Community efforts to control mosquito populations and raise awareness play a vital role in minimizing the risk of dengue fever for everyone living in or visiting these high-risk areas.
Dengue fever presents a wide range of symptoms, which can vary in severity. Typically, the disease starts with a sudden high fever, often reaching up to 104°F (40°C), accompanied by severe headaches, intense joint and muscle pain, and pain behind the eyes. Additionally, individuals with dengue fever may experience a characteristic rash, which can spread across the body and sometimes be accompanied by mild bleeding from the gums or nose. Fatigue, weakness, and abdominal pain are also common symptoms. While most cases of dengue fever are mild and can be managed with rest and hydration, severe forms of the disease, known as dengue hemorrhagic fever and dengue shock syndrome, can lead to life-threatening complications, including bleeding disorders and organ failure. Timely medical evaluation and care are essential to monitor and manage symptoms and prevent complications in severe cases.
