Why are chikungunya and mpox spreading locally now?
Chikungunya has seen its first local case in Hong Kong in October 2025, likely due to the presence of infected mosquitoes in the area. Mpox, previously linked to specific risk groups, is now spreading within communities in the UK and US, possibly because of increased travel and changing social behaviors. Seasonal factors and climate conditions also play a role in mosquito activity and virus transmission.
