Recently, an article about trypanosomiasis circulated online. According to the online article, a small insect called the cone bug will spread the new type of AIDS, and Guangzhou is currently "catching" this small worm with a bounty of 8 yuan per insect. In Guangxi, before the end of September, citizens who catch cone bugs can receive a reward of 20 yuan per piece.

The whole city offers a reward for cone bugs
What exactly is the worm?
On July 5, the WeChat public account of the Guangzhou Municipal Center for Disease Control and Prevention (Guangzhou CDC i Health) issued a document calling on Guangzhou residents to "find insects, find people" - find cones and bugs, find potential patients with American trypanosomiasis. For residents who find cone bugs, after confirmation, the CDC will provide a reward of 8 yuan per animal and health consulting services.
What exactly is the "sacred" of the trypano bug? On July 16, the Autonomous Region Center for Disease Control and Prevention held a media interview meeting and did a popular science popularization of this "wanted" little bug.
What is Atrium bugs
According to Yang Yichao, director of the Institute for Parasitic Disease Control and Control of the Autonomous Region Center for Disease Control and Prevention, at present, the national key research and development plan: "The dynamic distribution of invasive vector organisms related to important tropical diseases and their pathogens in the construction of resource banks" is under study. Trypanosomiasis is one of the research projects. Many provinces across the country have participated in the research on this topic, including Guangxi and Guangdong. This is also the reason why Guangzhou issued a bounty to "catch" the cone bug.
As early as 2016, the Autonomous Region Center for Disease Control and Prevention has released a "reward list" on a small scale to look for Guangxi cone bugs. Judging from the insect bodies collected so far, there are triatomine bugs in Nanning, Yulin, Qinzhou, Beihai, Hepu, Ningming and other places.
The triatomine bugs in Guangxi are the red-banded cone bugs, which look like "stink bugs" and have adult bodies about 2.5 cm long, slightly oval in shape, dark or dark brown in color, and red or yellow spots on the thorax, wings and ventral margins. There is a suction mouthpiece in front of the head, which is elongated when feeding and can directly puncture the subcutaneous blood vessels to suck blood.
Trypanos bugs range from nymphs to adults.
Yang Yichao said that trypanosomiasis loves to suck the blood of some vertebrates, especially mammals, and people are naturally not spared. And it likes to pick places with thin skin, such as eyelids, faces and lips, so the trypanos bug has the name of "kissing bug".

Will it infect the "new AIDS"?
It is understood that after the Guangzhou Disease Control Department issued a reward order for catching insects, there are also citizens in Guangxi who are concerned about this matter. At present, the AUTONOMOUS CDC has received about ten health consultation calls about the insect, and cases of bites have also been found.
Dr. Shi Yunliang, director of the Institute for Parasitic Disease Control and Control of the Autonomous Region Center for Disease Control and Prevention, said that there were previous cases of trypanosomile bites in Guangxi: a citizen living in the Wuyi Road area of Nanning City was bitten by a cone bug when he was asleep. Usually, the symptoms of being bitten are a series of allergic reactions, such as local redness, swelling, the appearance of plaque, and pain at the place of being bitten.
So, does trypanosomia really infect the "new AIDS"?
Shi Yunliang explained that the trypano bug itself is not fatally toxic, but because of its "eating habits", it will make it a vector of pathogens and infect some diseases.
The "new HIV" recently mentioned online is actually Trypanosomiasis of america. Previously, trypanosomiasis was mainly endemic in Central and South America, and was discovered by Dr. Chagas, hence the name Chagas disease. Trypanosomiasis is a parasite, and just as malaria can be found in mosquitoes, trypanosomiasis is transmitted by biting a human by sucking blood from a host with trypanosomes.
Trypanosomiasis is known as the "new HIV" because it is difficult to detect, and it also has a long incubation period and is difficult to treat. There are currently no preventable vaccines or drugs for the disease, and its incubation period can be as long as 20 to 30 years, and by the time it is discovered, the patient is usually terminally ill. But the difference between the two is that AIDS is a virus transmission, the patient's immune system is seriously damaged and then dies; the pathogen of American trypanosomiasis is a parasite, after the pathogen invades the human body, causing damage to the heart, intestines and other digestive organs, irreversible and difficult to cure.
Shi Yunliang said that according to the record, the incidence of American trypanosomiasis is the most serious in Latin America, but with the facilitation of transportation, the disease is spreading, and there are already cases in Japan and South Korea, near China. But there is no need for the public to panic, and no such imported cases have been detected in China.

Guangxi issued a reward order
Reward 20 yuan / only
Yang Yichao said that the current research is precisely to understand the distribution of trypanosomiasis in China, and to formulate corresponding measures as soon as possible to minimize the harm.
It is understood that Guangxi's "bounty" for trypanosomiasis is still underway. Yang Yichao said that the found cone bugs like to hide in places where wood is densely stacked, such as old wooden houses, farm firewood piles, and in addition, poultry breeding places, such as chicken and duck cages, have also found cone bugs. Cone bugs prefer shade and often hide under the tiles of houses and in the corners of walls.
Cone bugs found in wood.
Trypanosus bugs love to be active at night, and may to November in Guangxi is their active period. If the public sees the cone bug, it can be packed in a mineral water bottle, poke a few small holes for it to breathe, and after recording the time and place of capture, they can contact the Autonomous Region CDC to "receive the reward".
It is understood that the "bounty" for trypanosomiasis ends at the end of September. Members of the public who catch cone bugs will receive a reward of $20 per piece, and up to 5 trypanos bugs caught by the same person in the same place will receive a reward, that is, a maximum of $100.
Yang Yichao reminded the public that when "catching" the cone bugs, they should do a good job of protection and not be bitten by the insects. The public should also raise awareness of self-protection, and if bitten by trypanosomiles, they should immediately go to the hospital for medical examination without delay.
