guangdong province reported 775 cases in 6 days

guangdong province has entered the dengue fever epidemic season, and the risk of epidemic transmission is gradually increasing. in august, guangdong reported 1,220 cases of dengue fever, an increase of 987 cases from july.

according to the guangdong centers for disease control, from september 9 to 15, the province reported 775 new cases of dengue fever, an increase of 73 cases from last week. among them, 768 were local cases and 7 were imported cases. there were no new severe cases or deaths.

during these six days, foshan reported 296 local cases of dengue fever, becoming the city with the most reported cases among prefecture-level cities in guangdong province during the same period. at present, foshan has taken a series of measures to strictly prevent and control the dengue fever epidemic. zhao wei, an emergency management expert in guangzhou and director of the biosafety research center of the school of public health of southern medical university, said that dengue fever in guangzhou is mainly transmitted by aedes albopictus. guangzhou has experienced heavy rains for many days, which is conducive to the growth and reproduction of aedes mosquitoes, and the density of aedes mosquitoes (breteau index) is directly related to the risk of dengue fever, so rainfall will increase the risk of dengue fever outbreaks. "from the past, guangzhou's summer and autumn seasons are the peak seasons for dengue fever every year, which is superimposed with the rainfall in guangzhou. recently, the dengue fever epidemic in southeast asia has been relatively serious, and there is a high risk of local transmission after being imported into guangzhou." on september 20, the guangzhou cdc issued a reminder that guangzhou has entered the dengue fever epidemic season. 97 streets and towns in 11 districts of guangzhou city involve local cases of dengue fever, and 32 streets and towns in 11 districts involve imported cases of dengue fever.
