Blood transfusion was formerly the second-most common mode of transmission for Chagas disease, but the development and implementation of blood bank screening tests has dramatically reduced this risk in the 21st century.

However, in regions where the sylvatic habitat and its fauna are thinned by economic exploitation and human habitation, such as in newly deforested areas, piassava palm culture areas, and some parts of the Amazon region, a human transmission cycle may develop as the insects search for new food sources. Trypanosoma cruzi can also be transmitted through blood transfusions, organ transplantation, transplacentally, and in laboratory accidents.


Retrieved 24 February For example, pacemakers and medications for irregular heartbeats, such as the anti-arrhythmia drug amiodaronemay be life saving for some patients with chronic cardiac disease, [43] while surgery may be required for megaintestine.

Infectious diseases — Parasitic disease: If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. In Central America and Mexico, the main vector species lives both inside dwellings and in uninhabited areas.

In both zones, Chagas occurs almost exclusively in rural areas, where triatomines breed and feed on the more than species from 24 families of domestic and wild mammals, as well as humans, that are the natural reservoirs of T.

For more information see: Drugs of choice include azole or nitro derivatives, such as benznidazole [41] or nifurtimox. Management uniquely involves addressing selective incremental failure of the parasympathetic nervous system. Later studies showed squirrel monkeys were also vulnerable to infection. Public domain Public domain false false. Dense vegetation such as that of tropical rainforests and urban habitats are not ideal for the establishment of the human transmission cycle. Isr J Med Sci.


The disease was named after the Brazilian physician and epidemiologist Carlos Chagaswho first described it in N Engl J Med. Until recently, however, Chagas disease was considered a contraindication for the procedure, since the heart damage could recur as the parasite was expected to seize the opportunity provided by the immunosuppression that follows surgery.

For example, intracellular amastigotes destroy the intramural neurons of the autonomic nervous system in the intestine and heart, leading to megaintestine and heart aneurysmsrespectively.
