Guangdong disease control experts answer your answer

1. Popular status and trend

Q:

Recently, the departure of dengue fever in many countries, Singapore, Brazil and other countries are particularly serious. What are the reasons behind it?

A::

Since the beginning of this year, Singapore, Brazil and other countries have seriously developed fever, which may be:

First, the new crowns are popular, and countries have invested a large number of public health personnel and resources to respond to the epidemic of new crown pneumonia, and mosquito media control personnel have decreased. At the same time, insufficient supply of pesticides and other supplies and facilities has led to a large number of mosquito breeding, and the risk of dengue fever increases.

The second is global warming. According to reports, there are warm, rainy and humid weather in Brazil, Singapore and other countries, which will help mosquito breeding and virus spread.

Third, dengue fever has been localized in these countries and regions, and there are local cases all year round. Once the temperature and humidity increase, the density of mosquito media will increase, resulting in an increase in dengue heat cases.

Q:

As early as May, Guangdong Province reported the first case of dengue fever overseas input cases. What is the current outbreak in the province? Is there a new change or development trend compared to previous years?

A::

According to the epidemic data released by the Guangdong Provincial Commission for Health and Health, as of May 31, 2022, Guangdong Province reported a total of 1 case of overseas input cases in the Revolution, which was the lowest level in the same period in the past 10 years.

Since 2020, affected by the joint prevention and control measures of new crown pneumonia, dengue fever input cases have been significantly reduced, which has led to a significant decrease in the dengue fever in the province. In 2020, it decreased by 99%compared with 2019 and 71%decreased in 2020 compared with 2020.

Q:

What is the current situation of dengue fever in my country? Is there soaring? Is the current risk of overseas input high?

A::

According to the epidemic data released by the National Disease Prevention and Control Bureau, as of May 31, 2022, a total of 4 cases of dengue fever reported by the country, a decrease of 75%compared with the same period last year (16 cases).

In Guangdong's entry flights, the proportion of flights from high dengue fever in Africa and Southeast Asia is relatively high, and the risks of dengue fever will continue to exist from overseas. However, due to my country's entry and control over the entry of overseas immigration, the risk of local dengue fever epidemic is low.

2. How to prevent dengue fever

Q:

What are the typical symptoms of dengue fever? Dengue fever infection, influenza, and new coronal virus infection will all show symptoms such as fever and muscle pain. How can the three be distinguished?

A::

Typical symptoms of dengue fever are: sudden high fever, obvious fatigue, "three pain" (headache, or orchem, muscle, joints, and skeleton pain), "three red signs" (noodles, necks, chest flushing) Several congestive rashes or dotted bleeding rash).

Popular cold can cause high fever and muscle soreness. At the same time, symptoms of upper respiratory infection such as sore throat, cough, and runny nose. No rash, severe symptoms of poisoning in the whole body, influenza virus spreads through the respiratory tract, fast transmission speed, and a large number of similar patients will occur in a short period of time.

The new coronal virus infection is mainly manifested by fever, dry cough, and fatigue. Some patients may have symptoms such as nasal congestion, runny nose, sore throat, muscle pain, and smell (taste).

Based on clinical symptoms, it is difficult to distinguish from infectious diseases such as dengue fever and influenza. Laboratory testing is the key to diagnosis. For cases of suspected dengue fever, the monitoring of virus NS1 antigen detection must be carried out in time to achieve early diagnosis, early reporting, early isolation, and early treatment of cases.

Q:

As an individual, what measures must be taken to prevent dengue fever?

A::

Anti -mosquito and mosquitoes are the key to preventing dengue fever. Clearing water is the basis for mosquito preventing mosquitoes.

(1) Clear water

Clear or inverted water -saving containers on the balcony rooftop of the front house; the planting water planting plants should be replaced regularly, at least once every week, and water change. The tray and other stagnant water; put all the jars and bottles used in the covered trash can or inverted in rainproof places; clean up the accumulation of debris and old garbage in all corners of the house and the front of the house; Bamboo tube and tree hole; discard the abolition of tires should be discarded in time, and temporarily be idle, sand filling, sand filing or putting on the mosquito. (2) Mosquito extinguishing insects

Family mosquito -extinguishing electrical mosquito coils, electric heating mosquitoes, electric mosquito shoots, etc.; Use mosquito coils, and use instructions to repel mosquitoes and mosquitoes, put mosquito coils on the ventilation direction;

(3) Anti -bite

Families can use gauze doors, screens, mosquito nets and other anti -mosquito equipment; try to wear light -colored long -sleeved tops and trousers as much as possible; spray on the exposed skin and clothes, apply mosquito repellent (such as mosquitolamine, mosquito repellent, etc.) And according to the product description; avoid staying in the dark places such as shade, grass, gazebo, etc. in the shade of the shade of trees, grass, and gazebo during the frequent period of mosquitoes.

June-October is the traditional high-incidence season for dengue fever. If the people have discomfort, they will seek medical treatment as soon as possible. If fever, headache, skeletal muscle pain, joint pain, rash and other symptoms, pay attention to preventing mosquito preventive measures and seek medical treatment early.
