Why some chikungunya virus infections may turn chronic

Chikungunya virus, transmitted by infected Aedes mosquitoes, causes high fever and severe joint swelling and pain in affected individuals.

Understanding the mechanisms behind chronic chikungunya is crucial for developing better treatments and management strategies. This finding is particularly important for Puerto Rico and tropical regions where Aedes mosquitoes are prevalent.
