World Dengue Day
June 15 · Level 7 · #862 of 2238
Dengue is a viral infection spread by mosquitoes, and this day is a reminder that it can be prevented. Doctors and researchers use it to explain how to avoid bites and why the fight works best when whole communities join in.
How it is celebrated: health ministries and research institutes hold talks and awareness campaigns, and volunteers go street by street helping residents clear out anything that holds water, from old tyres to saucers under flower pots.
The Aedes mosquitoes that carry the virus bite mostly in daytime, and a bottle cap of rainwater is enough for them to breed in.
