This is a topic I can speak on with some authority....I had Chagas Disease. Caught it in Honduras.
Long story short...I left the country and went back 18 months later to fly a MEDRETE...basically a medical team sent in to remote areas to screen and treat the locals. This particular team I was flying happened to be screening for Chagas. After seeing some of the people brought in who had had the disease for years, I asked the docs about it, thought about how many times I had slept under thatch and woken up with bites on my face. So I got tested then and there. And popped a positive.
I had to go tthrough a fairly intensive treatment protocol, but I became parasite-free. The article is wrong in that respect. They can kill the bugs, they just can't reverse any damage done. Luckily, in my case, no heart damage was detected. I still get a heavy screening every year to look for problems, but after 11 years, I doubt anything will pop up.
I shudder to think of what my life would be like if I hadn't been the one flying those docs around on that particular MEDRETE....
Now. Onto the real issue....
The bug that carries this disease is very prevalent in the US. Most places call it an assassin bug. It just doesn't carry the parasite, and Chagas Disease was unheard of in the United States.
Until the explosion of illegal immigration in the last 10 years.
This is a decades-long chronic disease, and illegal immigrants who receive no medical screening are bringing it with them into the US. Chagas-positive assassin bugs have been found in Georgia, Texas, New Mexico and even Illinois. A baby in Texas was diagnosed positive after her mother noted swollen bug bites on her face after sleeping in her crib with a window open.
Nasty stuff....
