Dengue is a global and regional threat causing a major additional public health burden for all communities amidst the COVID-19 pandemic. This neglected tropical disease has a wide clinical spectrum which includes both severe and non-severe clinical manifestations. Dengue continuously spreads as a mosquito-borne viral disease throughout the Asia Pacific Region, and is no respecter of national borders. Nearly 75% of all dengue cases worldwide occur in Asia and the Pacific. National leaders recognize that preventive measures need to be taken at the regional level in order to protect people within their borders. ASEAN is a driving force in preparedness against dengue and all regional health threats.

Official figures as of June 27 put the number of infections at 52,601 and deaths at 190.

The WHO website says one modeling estimate indicates 390 million dengue virus infections per year (95% credible interval 284-528 million), of which 96 million (67-136 million) manifest clinically (with any severity of disease). Another study, on the prevalence of dengue, estimates that 3.9 billion people are at risk of infection with dengue viruses. Despite a risk of infection existing in 129 countries, 70% of the actual burden is in Asia.
The number of cases is increasing as the disease spreads to new areas including Europe. The threat of a possible widespread outbreak of dengue now exists in Europe; local transmission was reported for the first time in France and Croatia in 2010 and imported cases were detected in three other European countries. In 2012, an outbreak of dengue in Portugal’s Madeira archipelago resulted in over 2,000 cases, and imported cases were detected in mainland Portugal and 10 other countries in Europe.
Cases are now observed on an almost annual basis in the native populations of many European countries. Among travellers returning from low- and middle-income countries, dengue is the second most diagnosed cause of fever after malaria.
In 2020, dengue continues to affect many countries, with reports of increased 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.
The largest number of dengue cases ever reported globally was in 2019. All regions were affected, and dengue transmission was recorded in Afghanistan for the first time.
