After the rainstorms, mosquitoes increased
Diseases transmitted by mosquitoes
"Dengue fever" is not to be underestimated
It is essential to remember what this mosquito looks like
aedes
April 23rd
The Chinese Center for Disease Control and Prevention issued a reminder
When the rainy season arrives, precipitation increases
With the vector Aedes mosquito breeding in large numbers
Dengue fever also spread
At the same time, recently
Guangdong CDC also reminds:
Recently, there has been a large flow of inbound and outbound flows
A new round of strong convection "debuts"
The weather is hot and mosquitoes are frequent
Special vigilance is required for dengue fever
Dengue fever is mainly transmitted through the bite of Aedes mosquitoes
Dengue fever is an acute insect-borne infection caused by dengue virus. Because it causes severe pain, it is also known as "broken bone fever". Dengue fever does not spread from person to person and is mainly transmitted through the bite of Aedes mosquitoes, commonly known as Aedes versime.
In addition to Xinjiang, Qinghai, Inner Mongolia, Heilongjiang, Jilin and Ningxia, other provinces (autonomous regions and municipalities directly under the central government) in mainland China have the distribution of "spotted mosquitoes", and the transmission of dengue fever can theoretically occur. However, in the past, mainland dengue fever mainly affected southern provinces such as Yunnan and Guangdong.
Aedes mosquitoes generally hide in small stagnant water or containers in front of and behind houses, on balcony rooftops, including aquatic plants, flower pot bases, water storage containers, water dispenser water trays, discarded tires, etc.
Aedes mosquitoes are often active in: 7~10 a.m. and 4~7 p.m.
How can I tell if I have dengue fever?
Dengue fever is similar to influenza in that it is easy to confuse fever, fatigue, and pain. However, influenza generally occurs after contact with patients, and it is more likely to occur in winter and spring, and is often accompanied by respiratory infection symptoms such as sore throat, runny nose, cough, and sneezing.
Dengue fever has the following clinical manifestations:
1. Fever (up to 39°C): It is the most common symptom of dengue fever infection, and you feel very tired, sometimes with anorexia, nausea, stomach ache and diarrhea.
2. "Three pains, three reds": headache, orbital pain (feeling that the eyes are on fire), generalized musculoskeletal and joint pain (back pain), and flushing of the face, neck, and chest.
3. Skin rash: On the 3rd to 6th day of the disease, some patients will have a rash on the face and limbs, which is itchy and does not peel off, and will subside after 3-4 days.
4. Bleeding manifestations: Nosebleeds, bleeding gums, menorrhagia, subcutaneous bleeding, blood in the urine and other manifestations occur in individual cases after 5-8 days of fever.
Most people are infected with dengue fever
Symptoms are mild or asymptomatic, and the prognosis is good
Only a small number of patients will develop severe disease
Or even death
Guangzhou CDC: May or even earlier
Cases of dengue fever are likely
The Guangzhou Center for Disease Control and Prevention revealed on the 19th
Since the year
Dengue fever imported outbreak in Guangzhou
Came earlier than usual
And the number of imported cases has increased compared to last year
Qin Pengzhe, deputy director of the Guangzhou Center for Disease Control and Prevention, said that there were imported cases in January this year, which is related to the epidemic in Southeast Asia and South America, because there is a relatively large increase in the local area. At present, there have been more than a dozen imported cases, but all of them have been completely dealt with so far, and no further local cases have appeared.
According to the surveillance of Guangzhou CDC
From January of this year to now
Adult mosquito density in Guangzhou
That's higher than the same period in the last three years
Guangzhou CDC Prediction:
In May of this year
And even earlier
There is a high probability of dengue fever cases in Guangzhou
The Chinese Center for Disease Control and Prevention reminds that at present, Southeast Asia, South Asia, and Latin America, such as Indonesia, Malaysia, Thailand, Singapore, Bangladesh, Cambodia, Laos, Brazil, Argentina, Colombia, Paraguay and other countries have entered the epidemic season of dengue fever. When you travel to these areas, you must take mosquito prevention measures.
6 ways to prevent dengue fever
No stagnant water, no mosquitoes
No mosquitoes, no dengue fever
Guangdong CDC reminder
The prevention of dengue fever should be done in the following aspects
①
Turn over pots and cans, and clean up stagnant water frequently
Regularly "turn over pots and cans"
Such as flower pots, bottles and other containers that are prone to water accumulation
Aquatic PlantsRegular Watering
Or it is recommended to change to soil culture
②
Mosquito prevention and mosquito control, equipment in place
Install screen doors and windows at home, and hang mosquito nets when sleeping
Mosquito repellent and mosquito repellent equipment such as mosquito coils, mosquito repellents, and electric mosquito swatters are always available
③
Reduce exposure during high-risk periods
Mosquito infestation is frequent, reduce going out during periods
If you need to go out
Try not to spend time outdoors in shady places such as trees and grass
④
Wear a battle shirt to protect against mosquito bites
When you're out and about
Long-sleeved clothing + long pants (preferably light-colored) + insect repellent
⑤
Leaving the province, the whole process is mosquito prevention
Before you leave
Find out if the area is a dengue fever endemic area
Be prepared for mosquito protection
Mosquito prevention throughout the tour
If you have symptoms of "heat, pain, redness, and rash", you should seek medical attention in time
⑥
Take the initiative to declare and self-report the itinerary
Travel abroad
If you have a fever before entering the country, you should report it to customs immediately
If there are symptoms
Remember to inform your recent travel and residence history when you see you
