Despite their tiny size, diseases spread by mosquitos and other insects kill around 700,000 people every year.
SIGN THE PETITION TO MAKE A REALITY
World Mosquito Day
August 20, 2023
Mosquitos cause more death and disease than any other animal on the planet1
They are responsible for the spread of many deadly diseases, like Dengue, Malaria, Yellow Fever, Japanese Encephalitis and Zika. 1

Once infectious mosquitos can transmit dengue for the rest of their lives5
Mosquito transmission of dengue causes an estimated 40,000 deaths worldwide each year4
Mosquitos are spreading and invading new geographical areas7
Bites from infected Aedes species mosquitos transmit the dengue virus to humans4,5
Mosquito-borne disease suitable areas are expected to increase as a result of climate change8
Rising global temperatures by 2080 could put 1.4 billion more people at risk of dengue and malaria8
Dengue fever is also spread by mosquitos, called Aedes aegypti and Aedes albopictus.9
These mosquitos are present in many regions globally meaning almost half the world's population is at risk of dengue.11
By supporting World Mosquito Day and World Dengue Day, you can help to raise the worldwide profile of this potentially devastating disease.
This World Mosquito Day, make World Dengue Day a reality.
World Mosquito Day is recognized every year on August 20.
On this day in 1897, a scientist called Sir Ronald Ross discovered malaria in the stomach of a mosquito.
His work confirmed that mosquitoes were able to spread deadly diseases to people. 12
We now know that, as well as malaria, mosquitos spread many other diseases as well, including dengue fever.5

for World Mosquito Day
A day 120 years in the making. 12
More than a century after Sir Ronald Ross's discovery, mosquito-borne diseases are still both widespread and difficult to treat. Even with global efforts to curb their impact on vulnerable populations, these diseases cause hundreds of thousands of deaths each year.
Shine a spotlight on one of the world's deadlist creatures13
World Mosquito Day presents us all with an opportunity to raise awareness of the dangers of one of the world's deadliest creatures.
A global effort is needed to fight the global threat of disease14
World Malaria Day has helped spur initiatives that have cut annual malaria deaths in half since the year 2000. Help make a similar impact on dengue by signing the petition for World Dengue Day.
Dengue has spread to more than 120 countries and counting2
As reported by the WHO, dengue is spreading to new areas including Europe and explosive outbreaks are occurring.5
World Dengue Day was proposed by the International Society for Neglected Tropical Diseases15, Asian Dengue Voice and Action (ADVA) Group and dengue scientists around the world.
The aim is to acknowledge the global burden of dengue and drive efforts to make it a vaccine preventable disease.16,17
"The priority at global level would encourage regions to prioritize it, hopefully lifting it out of its Neglected Tropical Diseases status, creating more avenues for dengue related research and coming up with internationally accepted public health interventions." 9Sana Saleem (Ministry of Health Maldives)
"I believe that the establishment of a World Dengue Day could be a first step towards the creation of International plans to control the disease." 6Dr. A. Mosca (Medical Entomologist, Italy)
"For those in dengue areas, sharing more information about avoiding mosquito bites especially among school children, for example through radio, TV or even school itself, will be very beneficial in avoiding as many infections as possible." 6F. Weston (Parent, London)
"For my experience, education and sensitisation yield the best results in disease control - a global campaign is an important step in disease awareness and control."Dr Kenneth Arkoh Amoquandoh (Disease Control Officer, Ghana Health Services)
"Dengue is responsible for thousands of deaths each year, but resources for research, treatment, and prevention are still insufficient. It is necessary for people around the world to know the importance of dengue for this scenario to change." 8Dr. Raphael Ximenes (Postdoctoral Fellow, University Health Network, Canada)
"I believe that a World Dengue Day will allow the populations of endemic regions and decision makers to be aware of the public health importance of Dengue." 10Lassane Koala (Medical Entomologist at IRSS, Burkina Faso)
"Dengue is still and always will be a severe health problem in Indonesia. It causes thousands of deaths every year as well as millions of dollars lost for medical treatment. I myself was once hospitalized for dengue, and it was a terrible experience. I don’t want this misfortune to happen to other people." 10Hadian Sasmita (National Nuclear Energy Agency, Indonesia)
"World Dengue Day is one of the best ways to sensitize people about this disease and bring decision makers to take action." 10Zoumana Isaac Traore (World Health Organisation, Mauritania)
"In my opinion, the message of preventing Dengue is brought around the World, not only in developing countries, but also in the developed one." 10Nguyen Thao (Institut Pasteur, Vietnam)
"The increased focus on dengue provided by a World Dengue Day would have many varied and positive effects." 7Pr. Eliningaya J. Kweka (Tropical Pesticides Research Institute in Arusha, Tanzania)
