How do I know if I have Trypanosoma cruzi?
During the acute phase of infection, parasites may be seen circulating in the blood. The diagnosis of Chagas disease can be made by observation of the parasite in a blood smear by microscopic examination. A thick and thin blood smear are made and stained for visualization of parasites.
How is Trypanosoma cruzi transmitted to humans?
When people become infected by the parasite Trypanosoma cruzi, they can get Chagas disease. The feces of insects called triatomine, or “kissing” bugs, transmits the parasite to humans. These bugs feed on the blood of animals and humans at night, and then they defecate.
How long do Chagas disease symptoms last?
Chagas disease has an acute and a chronic phase. If untreated, infection is lifelong. Acute Chagas disease occurs immediately after infection, and can last up to a few weeks or months. During the acute phase, parasites may be found in the circulating blood.
What are the stages of Chagas disease?
There are three phases of the disease: acute, indeterminate and chronic. In acute infection, symptoms can occur immediately following infection and can last approximately 2 months.
What kills Trypanosoma cruzi?
To kill the parasite, Chagas disease can be treated with benznidazole or nifurtimox. Both medicines are nearly 100% effective in curing the disease if given soon after infection at the onset of the acute phase, including the cases of congenital transmission.
How do I know if I was bitten by a kissing bug?
Bite Marks Kissing bugs are so named because they like to bite around the mouth or eyes. You’ll often see 2-15 bite marks in one area and maybe redness and swelling. It might be hard to tell them apart from other bug bites, minor skin irritations, or infections.
How long does it take to get Chagas disease?
Signs and symptoms of the chronic phase of Chagas disease may occur 10 to 20 years after initial infection, or they may never occur. In severe cases, Chagas disease signs and symptoms may include: Irregular heartbeat.
What happens if a parasite bites you?
Parasites are not a disease, but they may spread diseases that can be fatal. However, many parasitic infections are treatable and preventable. If a person is experiencing a skin rash, abdominal pain, diarrhea, or other symptoms of a parasitic infection, they should speak with their doctor.
Does Chagas cause death?
Chagas disease causes approximately 10,000 deaths per year globally. Up to 30% of infected people develop symptoms. Chagas disease can cause: Stroke.
Is Trypanosoma cruzi curable?
Trypanosoma cruzi infection is curable if treatment is initiated soon after infection. In chronic patients, antiparasitic treatment can potentially prevent or curb disease progression and prevent transmission, for instance, mother-to-child infection.
When should you get tested for Chagas disease?
The optimal time to diagnose Chagas disease is during the acute phase of the illness, when the chance of eradicating the Trypanosoma cruzi (T. cruzi) infection with antitrypanosomal drugs is the highest.
