After the official announcement of the summer
The weather in Guangdong is thunderous
Sudden cliff-like cooling
But nevertheless
All kinds of mosquitoes still insist on "starting work"
In addition to disturbing sleep in the middle of the night
Mosquitoes can also transmit infectious diseases such as dengue
Recently, dengue fever outbreaks have occurred in many countries
Guangdong also released a "mosquito map"
Remind the public to take precautions against dengue fever
Shenzhen released this year's first "mosquito map"
On April 22, the Shenzhen CDC released the results of the city's Aedes mosquito density monitoring in the first half of April (January-15). Of the 425 monitoring points set up in the city, 32 were unqualified, accounting for 7.53%. Among the unqualified monitoring points, there were 3 medium density and 29 low density. All three medium-density monitoring points are residential areas.
The picture above is not only a map of Shenzhen mosquito "black spots" but also a "risk map" of dengue fever. Moderate density indicates a certain risk of dengue transmission.
The following figure is the "performance table" of mosquito monitoring in each district. The higher the score, the more qualified monitoring points and the higher the "safety factor".
There is no specific drug for dengue treatment, no vaccine to prevent it, and once it develops into a severe case, it can cause death due to the failure of vital organs.
