Trypanosomiasis is the transmission vector of American trypanosomiasis, which can cause irreversible harm to human health and can be called a "new type of AIDS". Patients with potential trypanosomiasis can avoid life-threatening risks if promptly diagnosed and treated.
This is also the reason why the Guangzhou Municipal Center for Disease Control and Prevention "looking for insects and finding people".
"New AIDS", with an incubation period of twenty or thirty years
According to the article, the cone bug is named because the head is narrow and cone-like, the adult body is about 25 mm long, oval-shaped, the tail tip is flat or flat, dark or dark brown, and the lateral edge of the abdomen has red or yellow spots. The larvae and adults of the triatomine bug will suck human blood, because they specialize in biting people's faces, and like to look for areas with thin skin, such as lips, eyelids, etc., so they are also called "kissing worms".

Trypanosomiasis is the vector of American trypanosomiasis and the global spread of trypanosomiasis should be noted.
The Shanghai Municipal Health and Family Planning Commission issued a paper in 2012 that Trypanosomiasis in the United States can cause changes in the heart, digestive tract and peripheral nervous system in the clinic, and the case fatality rate is high. With the integration of the global economy in recent years, the frequency of population movements has increased. The disease also spread from the Americas to Asia.
△ In 2011, it began to spread globally
The disease is transmitted in two ways, either through patients or storage hosts→ cone bugs → humans, and through blood transfusion, vertical mother-to-child transmission, or in the setting of organ transplantation and laboratory accidents. There are currently at least 40 known species of blood-sucking cone bugs that may cause transmission of the disease.

In addition, trypanosomiasis is extremely occult, with a hidden period of up to 20 to 30 years; the diagnosis rate of trypanosomiasis is low, there is no vaccine to prevent it, and there is no specific drug in the late stage of the disease, so some scholars even call it a "new type of AIDS".

Cone bugs mostly hide in gaps in walls or wooden objects, such as old wooden houses, flower pots and next to wooden piles in farmhouses, and go out at night. At night, they are also easy to find in barns, chicken nests, etc. where there are woodlands or fields.

The Guangzhou Municipal Center for Disease Control and Prevention said that through this investigation, it is hoped to clearly understand the distribution of cone bugs in China, cooperate with corresponding measures, and strive to minimize the harm.
Secure delivery to rewards
Just for more people to find worms
After the news was released, some netizens questioned, "What if I am bitten during the capture process?" Some netizens even said, "You have to catch a few cone bugs, raise a nest, and then you will get rich." ”
In response to this matter, the staff of the Guangzhou Municipal Center for Disease Control and Prevention said that at present, trypanosomiasis has not been found in Guangzhou, and calling on the public to "find insects and find people" is to grasp the vector status of the disease through "finding insects" and provide a basis for the implementation of efficient and accurate prevention and control; "finding people" can enable people in need to be diagnosed and treated in time to avoid life-threatening risks. A person in charge of the Cdronic Center of Nansha District, Guangzhou, said that since the publication of the article, it has received a number of calls from citizens, and 2 insects suspected of "cone bugs" have been sent to the Guangzhou CDC for identification.
For the practice of offering a reward of 8 yuan and the doubts of netizens, the person in charge said that it was to improve the enthusiasm of the public to "find insects and find people". Once the public finds the suspected "cone bug" bugs, they will not let them catch them directly, but ask them to take pictures, load them with mineral water bottles or other lidded containers within their capabilities, and then contact the personnel in charge of this work at the CDC in their districts. The staff will send the bugs to the Guangzhou Municipal Center for Disease Control and Prevention for identification, and rewards will be given after confirming that they are cone bugs.
How to prevent it?
According to the recommendations given by the Shanghai Municipal Health and Family Planning Commission, the main means of prevention of trypanosomiasis are as follows:
1. Improving living conditions and housing structure, such as applying lime and other paints to the walls of buildings, repairing and replacing roofs, etc., or spraying insecticides indoors, can prevent cone bugs from breeding and roosting indoors.
2. Eliminate the animal storage host as much as possible. Tourists should avoid sleeping in simple dwellings and use mosquito nets or insecticides.
3. In order to avoid the spread of blood transfusion, the blood bank should carry out blood trypanosoma serology, and 1:4000 gentian violet can be added to the blood 24 hours before the transfusion to kill trypanosomes. In addition, blood donors, organ providers and pregnant women should be promptly serological tested.
4. Anti-trypanosomiasis should be carried out as soon as possible in the acute stage, and the drugs used for treatment mainly include benzidazole or nifurmus.
