    Dengue is caused by any one of four related viruses transmitted by mosquitoes. Dengue has emerged as a worldwide problem only since the 1950s. The principal symptoms of dengue fever are high fever, severe headache, severe pain behind the eyes, joint pain, muscle and bone pain, rash, and mild bleeding (e.g., nose or gums bleed, easy bruising).

    There are a number of concerning dengue epidemics currently ongoing around the world. Médecins Sans Frontières (MSF) recently reported that an outbreak in Honduras has resulted in nearly 800 cases of severe dengue in 2019, more than 80% of which are children 15 years old or younger. Approximately 95% of these cases were reported from a single region in the country (Cortes). Jamaica has also reported increases in dengue cases in 2018 and 2019. There were an estimated 986 total dengue cases in 2018, which was more than four times the yearly total in 2017 (215 total cases). During both December 2018 and January 2019, the number of reported cases exceeded the epidemic threshold for those months. To address the rise in cases, the Jamaican Ministry of Health established an Emergency Operations Center on December 27, 2018 and declared a dengue outbreak on January 3, 2019. Currently, according to PAHO estimates, there were a total of 981 cases reported in the first 5 weeks of 2019 in Jamaic...

    Characterized by flu-like symptoms including high fever, headache, joint pain, and rash, dengue is spread by bites from Aedes aegypti and Aedes albopictus mosquitoes. While other diseases including Zika and chikungunya are also spread Aedes aegypti, dengue is considered the fastest-spreading vector-borne viral disease worldwide. Generally, symptomsbegin within a week of infection and can last between 3 and 10 days. Infections can sometimes cause potentially lethal complications, including dengue hemorrhagic fever and dengue shock syndrome. Dengue fevercan be caused by dengue viral serotypes 1-4, but infection with one serotype does not provide any immunity against infections caused by other serotypes. In fact, subsequent infections are actually associated with an increased risk of developing severe dengue disease. This key detail is important to note when discussing challenges facing dengue control programs. Compared to just 9 countries reporting severe dengue epidemics prior to 197...

    Aedes mosquitoes are highly resilient and can adapt well to different environments, making it difficult to control vector populations and interrupt transmission. Female mosquitoes can lay thousands of eggs in many different types of places, from water containers to septic tanks and toilets. Additionally, eggs can survive without water for months, so even if control measures were able to remove all larvae, pupae, and adult mosquitoes in a particular location, the population could quickly re-emerge once dessicated eggs remaining in the environment are exposed to water. Meta-analyses conducted by the Special Programme for Research and Training in Tropical Diseases (TDR) have assessed interventions aimed at controlling dengue transmission. Placing screenson windows and doors has been shown to be a popular and effective in impacting dengue transmission. Other interventions such as indoor residual house spraying have also been explored and found to be efficient in standalone studies, but...

    Once a disease that appeared to affect only 9 countries just a few decades ago, dengue is now endemic in areas that affect nearly half the global population. The longer-term global rise in dengue incidence, along with the increased occurrence of localized outbreaks—despite the availability of a vaccine—highlights the challenge facing dengue control efforts worldwide. Mitigating the global burden of dengue faces a number of barriers, including the ability of Aedesmosquito populations to flourish in spite of various control measures, difficulties in detecting and diagnosing dengue cases, and the unique epidemiological characteristics that limit the efficacy of available vaccines. Continued dedication to surveillance efforts, particularly syndromic surveillance, and advanced research and development for more effective vaccines could fill existing gaps that currently limit the ability to control the spread of this disease. Outbreak Observatory aims to collect information on challenges a...
