Guangzhou CDC: Earlier than in previous years, the number has increased
Dengue fever in Guangzhou is mainly caused by local transmission caused by imported cases. According to the Guangzhou Center for Disease Control and Prevention, since the beginning of this year, the imported dengue fever epidemic in Guangzhou has come earlier than in previous years, and the number of imported cases has increased compared with last year.
The deputy director of the Guangzhou Center for Disease Control and Prevention said: "The epidemic in Southeast Asia and the dengue fever epidemic in South America is now more serious, and it will be heavier than in previous years, the second point is because the passenger flow of our international routes continues to rise, which also brings us greater import risks, and the third point is that this year is the earliest year since 1961, Guangzhou entered the summer, and the summer will enter on March 23, and the high temperature will also lead to the breeding of mosquitoes." ”
"There were imported cases in January this year, which is also related to the epidemic in Southeast Asia and South America just mentioned, because there is a relatively large increase in the local area, and the number of second cases is very large, there are more than a dozen, and we already have more than a dozen imported cases, but they have all been completely dealt with, and there are no secondary local cases. ”
According to the monitoring of Guangzhou CDC, from January this year to now, the density of adult mosquitoes in Guangzhou is higher than the same period in the past three years, so the city CDC predicts that in May this year, or even earlier, there will be a high probability of dengue fever cases in Guangzhou.
At the time of the disease, it is more painful than a broken bone, and if it is serious, it will be fatal
Dengue fever is an acute vector-borne infection caused by the dengue virus, also known as "broken bone fever" because of its severe pain, dengue fever does not "spread from person to person" and is mainly transmitted through the bite of Aedes mosquitoes.
Aedes mosquitoes generally hide in small stagnant water or containers on front and back balconies, rooftops, including aquatic plants, flower pot bases, water storage containers, water dispenser water trays, and discarded tires.
Aedes mosquitoes are often active in: 7-10 a.m. and 4-7 p.m.
