China's CDC Warns of Rising Vector-Borne Disease Risk as Dengue, Chikungunya Cases Spike in South

According to Jin10, China's National Disease Control and Prevention Administration issued a public health alert on July 16, warning that vector-borne disease outbreak risks have increased as summer progresses. Mosquito breeding activity has intensified and human mobility has grown, raising concerns over dengue fever and chikungunya virus clustering outbreaks in southern provinces, with heightened risks of imported cases triggering local transmission.

Respiratory tract infectious diseases nationwide remain at low circulation levels, though rhinovirus and parainfluenza virus show moderate activity. COVID-19 continues at low prevalence. Recent flooding in multiple regions has compounded risks, potentially creating conditions for vector-borne disease proliferation and gastrointestinal illness spread in affected areas.
