It insisted in increasing information campaigns about this issue, keeping constant monitoring and taking immediate action to prevent infection outbreaks, especially in schools.

Besides record rainfall, this fall China is having very low temperatures. For example, Beijing on Sunday reported temperatures below zero, the lowest ones in 52 years.
