We have started to monitor the distributions of species of Triatoma and Paratriatoma in Southern California, using light traps. During the season of 2007 (June-August), we exclusively collected
specimens of Triatoma protracta and Paratriatoma hirsuta. At most localities, only single specimens of T. protacta were found, but entomologist Chris Conlan, who is running a light trap at his house in San Diego Co. supplied us with hundreds of specimens collected over a 2 month period of time.

Dr. Rassi in Goiania reports that two months after Magdal received his implantable defibrillator the device fired, resetting his heart's rhythm. When last examined in September, he was doing very well.

Thanks so much for your wisdom. I read somewhere they can carry up to 50 different parasites infections. Check this out.

It's the poop it leaves from which the infection springs. As I recall, there can be some irritation from that poop's reaction to the skin. People often scratch that after the fact and it can become inflamed (with the broken skin then letting in the infection) but I do not recall having read about a hallmark rash.
I'm sure there may be links somewhere to photos of the kinds of irritation, though. There may be a foundation site for Chagas.
As the bites usually happen during the night, people are usually unaware.
