Vinchuca kissing bug

Triatoma infestans

需要看医生很少致命，但被咬了要去看医生。

咬伤

The vinchuca, also called the kissing bug, is a blood-sucking bug found in South America. It is the most important carrier of a parasite that causes Chagas disease, and it is common in homes in the Southern Cone region.1

怎样认出它

Darwin called it the great black bug of the Pampas.1
It is soft and wingless.1
It is about an inch long, roughly 2.5 cm.1
Before feeding it is thin; after sucking blood it becomes round and bloated.1

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它对人有多危险？

对人的危险: 严重被咬了要去看医生。死亡非常罕见。

It is the most important carrier of the parasite Trypanosoma cruzi, which can lead to Chagas disease. The parasite is passed on through the bug's faeces, not through feeding. Darwin is speculated to have died from chronic Chagas disease. A regional control programme, the Southern Cone Initiative managed by PAHO, works to control it.1

如果它咬人

被毛毛虫的蜇毛扎到：用胶带把毛粘掉，再清洗皮肤。不要揉。
被咬：清洗并冷敷。如果感到不适或容易出血，就去看医生。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

Charles Darwin wrote about being attacked by one on 26 March 1835, during the Beagle survey voyage.1

Transmission of the parasite happens through its faeces, not through the act of feeding.1

Transmission rates are higher in areas with few bugs, because bugs in crowded areas interrupt each other's meals and often do not get a full blood meal.1

It tends to displace other Triatominae vectors of Chagas, such as Panstrongylus megistus and T. sordida.1

Brazil's spread of this bug between 1955 and 1964 is likely due to immigrants moving north from the south.1
