How did Singapore manage dengue?
The Singapore dengue programme relies predominantly on source reduction and larviciding using Bti, which are implemented throughout the year through community and programme efforts. In the first 6 months of 2019, approximately 60% of vector habitats were found in residential premises, rising to 70% in cluster areas.

Change water and scrub the insides of flower vases once a week.
Is dengue a genetic disease?
The four dengue viruses are similar — they share approximately 65% of their genomes — but even within a single serotype, there is some genetic variation. Despite these variations, infection with each of the dengue serotypes results in the same disease and range of clinical symptoms.
How can we prevent dengue case?
5 Ways to Avoid Dengue Fever Are:
- Reduce Mosquito Habitat: The mosquitoes which breed dengue thrive in stagnant water containing objects like tires, plastic covers, flower pots, pet’s water bowls, etc.
- Stay in well-screened houses:
- Use Mosquito Repellents:
- Wear Protective Clothing:
- Sleep Under Mosquito-net:
How do you control arthropods?
These include physical measures such as heat or cold; chemical poisoning (insecticides); dehydration; or biological interference with the arthropods’ development in some way or another, by chemical repellents, by trapping by attractants, whether sexual or food, by destruction of their habitat, by preventing their …
How do you control insect vectors?
Insecticides, larvicides, rodenticides, Lethal ovitraps and repellents can be used to control vectors. For example, larvicides can be used in mosquito breeding zones; insecticides can be applied to house walls or bed nets, and use of personal repellents can reduce incidence of insect bites and thus infection.
Who invented dengue vaccine?
A vaccine to prevent dengue fever discovered by a Saint Louis University researcher in 1997 and now licensed worldwide by Sanofi Pasteur has been approved for use in Mexico.
