Justify
Impact on populations
elderly, young children, and individuals with underlying health conditions, might be more susceptible to severe complications from chikungunya infection.
Rapid spread
Aedes have high reproductive rate
- increased travel, and global warming may contribute to the expansion of the mosquito's habitat, leading to the rapid spread of the disease.
Medical importance
To differentiate Chikungunya from dengue fever, the study addresses a critical gap in knowledge, especially in regions where both diseases are endemic
no treatment for chikungunya and no vaccine to prevent it. Only treatment to manage the symptoms will be given
Risk of re-emergence
Chikungunya can re-emerge in areas where the Aedes mosquitoes are present, leading to recurring outbreaks.
