Health Policies to Control Chagas Disease Transmission in European Countries
In Chagas-endemic areas, the main mode of transmission is through an insect vector called a triatomine bug. Archived from the original on 9 May 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.
Aches, pains, and generally flu-like symptoms are also not uncommon after initial infection. With the exception of blood derivatives such as fractionated antibodiesall blood components are infective.
United Kingdom Health Protection Agency. The clinical manifestations of Chagas disease are due to cell death in the target tissues that occurs during the infective cycle, by sequentially inducing an inflammatory responsecellular lesionsand fibrosis.
Safety Every product meets or exceeds U. In Central America and Mexico, the main vector species lives both inside dwellings and in uninhabited areas.

It was first identified by Brazilian hygienist and bacteriologist, Carlos Chagas, in Nifurtimox and benznidazole are the only available medicines with proven efficacy against Trypanosoma cruzi infection in acute, congenital infection and early chronic infection.
Isolated cases exhibit central nervous system involvement, including dementiaconfusion, chronic encephalopathy and sensory and motor deficits.
It is hoped that it will be commercially available by Guidance on the Microbioolgical safety of human organ, tissues and cells used in transplantation. Triatominae harbored a flagellate protozoan, a new species of the genus Trypanosomaand was able to demonstrate experimentally that it could be transmitted to marmoset monkeys that were bitten by the infected bug.
Sincethe number of reported cases has alarmingly dii, particularly in Spain and, chagaw a lesser extent, in Italy and Switzerland  — .
Vaccination with Trypanosoma rangeli has produced positive results in animal models. To understand the magnitude of the problem, some economic studies have calculated the chagass cost of the disease worldwide at around 7,, American dollars per year which is mainly due to cardiovascular disease and early mortality.

The information was validated when the directive, legislation, protocol, or document was obtained and accordingly, it was checked to see if the document contained a specific mention about how to control T. It is estimated that 6. Archived from the original on 1 October Moreover, in countries where a directive already exists, we have not evaluated the correct implementation of the directive or policy.
Dense vegetation such as that of tropical rainforests and urban chagss are not ideal for the establishment of the human transmission cycle. Regarding congenital transmission, several studies have reported a rate of seroprevalence in Europe from 1. For the rest of the European countries, the official directives either exclude donations only in patients confirmed to be infected, or do not apply any measure.
Archived from the original on 10 June Autonomic disease imparted by Chagas si eventually result in megaesophagus, megacolon and accelerated dilated cardiomyopathy.
