China CDC warns summer mosquito breeding and higher population mobility have increased the risk of vector‑borne disease outbreaks; imported cases raise local transmission risk, and southern provinces face elevated risk of dengue and chikungunya clusters. Nationwide respiratory infections are at low circulation overall; rhinovirus and parainfluenza show activity and COVID‑19 remains at low circulation. Entering the July–August rainy season, widespread floods may cause sanitation problems, threaten food and drinking‑water safety, alter vector and host‑animal activity, and raise intestinal, respiratory and insect‑borne disease risks in affected areas.
