Do you know about - tour condition - Chaga's Disease
Health South! Again, for I know. Ready to share new things that are useful. You and your friends.Some of us travel to Central and South America for assorted reasons. Some go to volunteer at a curative hospital or to help out in a poor rural community. Others go for jungle and environmental adventures.
What I said. It isn't outcome that the actual about Health South. You read this article for information about that need to know is Health South.How is tour condition - Chaga's Disease
While in rural areas of Central and South America, there lurks a danger found in the trees or maybe the housing you are staying in, it's called the Triatoma or "kissing" bug.
These insects often carry for life the parasite, Trypanosoma cruzi. T. Cruzi is a comma shaped flagellated toady and the cause of an acute and persisting disease called Chagas.
The triatoma bug can be found in poorly constructed homes, with cracks and crevices in the walls or those with thatch roofs. They can also be found in palm trees and the fronds.
Usually at night while sleeping, the insect feeds on population or other mammals. While feeding the insect defecates and the infected feces gets rubbed into the bite wound, eyes abrasions or other skin wounds.
The toady invades macrophages at or near the site of entry. Here they transform, multiply and rupture from the cells 4-5 days later and enter the blood stream and tissue spaces.
Initial infection with Chagas is typically asymptomatic. Acute disease may manifest symptoms after a incorporate of weeks.
Reddening of the skin (Chagoma) or edema nearby the eye (Romana's sign) may be seen, albeit uncommon.
Fever, malaise, enlarged liver and spleen are part of the acute syndrome. 10% of population invent acute myocaditis with congestive heart failure. This acute disease can be fatal.
After a latent period which may last for years, the infected man may invent persisting disease (20-40%). The most serious consequences are cardiomyopathy (in determined areas it's the important cause of death in men less than 45 years of age) and megacolon/megaesophogus.
Trypanosoma cruzi can also be transmitted via congenital transmission (mother to baby), straight through blood transfusions and organ transplants, and some cases of transmission straight through feces contaminated food.
About 150 mammals beside humans may serve as reservoirs of the parasite. Dogs, cats, opossoms and rats are among the animals.
Diagnosis for Chaga's is by finding the toady in a blood sample or by antibody detection.
There is no vaccine for Chaga's, so preventive measures should consist of insecticide spraying of infested houses.
Insecticide-impregnated bed nets may sell out the risk of infection for travelers who cannot avoid camping, sleeping outdoors, or sleeping in poorly constructed houses in endemic areas.
Nifurtimox or benznidazole is used to treat in the acute phase. These drugs are available in major hospitals in endemic areas.
Heart failure and arrhythmias in Chagas' disease are treated as they are in other patients with similar cardiac problems.
It is estimated that at least 100,000 population are infected with T.cruzi in North America, mainly immigrants from endemic countries.
