Chagas Disease: Small Parasitic InsectsAre Responsible For Spreading This Disease to the USA

By Graeme Dinnen


An illness being incorrectly dubbed the "new AIDS" is being spread by parasitic insects from Latin America northwards to the United States.





Chagas Disease (also called American Trypanosomiasis) is carried by a small black wingless beetle called the Triatoma bug that sucks human blood in the area around the lips. As a result it has come to be known as the "kissing bug". The disease can also be spread from human to human through organ transplantation, from a mother to her developing foetus and even blood transfusions. It can also spread through the ingestion of contaminated foods.





How is Chagas Being Spread?

Requiring no passports at the US border, these bugs are incredibly difficult to detect. Chagas disease has infected over 300 thousand people in the United States and somewhere in the area of 8 million people globally. Once confined to South and Central American countries, the disease is spreading through infected travellers going north to the USA or other countries such as the UK and Europe by infected carriers. The beetle feeds round the lips of sleepers, earning it the nickname "the kissing bug". Once fed it releases a parasite called Trypanosoma cruzi. A waking person scratches the eggs and unwittingly smears them under their fingernails and into the pores and mouth.





Chagas Disease Symptoms



Chagas Disease has a long incubation period and uses considerable stealth to avoid detection. There are only two stages - acute and severe. Common symptoms in the acute stage include general illnesses, high fevers, dermal conditions, brain toxicity, unusual irritations in the digestive tract or a swelling in typically just one eye. Then a remission may set in for up to a few years, but don't be fooled - it's only becoming more virulent. Sufferers will then start to experience constipation and painful digestive issues. At this point the heart and intestines swell until they burst, causing sudden death.





Can Chagas disease be prevented?

Antiparasitic treatments for Chagas Disease will help delay or even perhaps prevent the condition developing. As usual prevention is always better than trying to find effective remedies once the condition has set in. Known in Latin America as a disease of the poor, there's a resultant stigma attached to the condition and consequently there isn't much money invested in finding new treatments.
