On August 2nd， media reports indicated the presence of the Asian tiger mosquito (Aedes albopictus) in several northern provinces.
In response， experts have pointed out that the risk of Chikungunya virus transmission in northern regions is relatively low. While mosquito repellents such as sachets and mugwort may offer some efficacy， they are not a guarantee. Therefore， strengthening personal protection against mosquito-borne diseases and minimizing mosquito bites is crucial.
Chikungunya fever is an acute infectious disease caused by the Chikungunya virus， transmitted through the bite of a mosquito. Its primary clinical features include fever， joint pain， and rash. The disease is predominantly prevalent in Southeast Asia， South Asia， and Africa.
Relevant experts have further elaborated that after infection with the Chikungunya virus， key symptoms in patients include sudden high fever (temperature exceeding 39°C)， symmetrical polyarthralgia， and rash， with most cases being mild. However， more severe illness can occur in high-risk groups， such as infants， individuals over 65 years of age， and those with underlying health conditions like hypertension， diabetes， or heart disease.
To enhance personal protection， it is advised to wear light-colored， long-sleeved clothing and long pants when outdoors to reduce exposed skin. It is also recommended to avoid prolonged stays in shaded areas， tall grass， or near water bodies， as these are common habitats for mosquitoes.
