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.
