Guadalajara, Jalisco. - The Chagas disease is a public health problem both because its transmitter is an insect of Mexico and Jalisco are endemic, but also because its long-term effects are devastating.
The effect of this disease caused by a bug bite , affects all striated muscles of the heart, esophagus and large intestine, the researcher said the Mexican Social Security Institute (IMSS) in Jalisco, Alberto Villasenor Sierra.
The expert explained that the world has 7.7 million infected people in 21 endemic countries, including Mexico.
He added that an important point about this zoonosis (a disease transmitted from animal to human) is that in the United States, one in 30 000 blood donors carry the parasite responsible for this pathology.
The main mechanism of transmission of Chagas disease , is the sting of a triatoma is colloquially known in Mexico as nosed bug or kissing bug feeds on blood and he said the specialist.
When chopping , the Animal excrement and it frees content is the parasite trypanosome cruzi once in the host, is located in striated muscles that, due to be carefully irrigated blood vessels are an excellent habitat for feeding and reproduction, detailed .
He emphasized that the injury that causes the sting of this bug is very characteristic, both known as chagoma, this is a big welt, five to seven centimeters in diameter in the center hole can be seen easily visible.
It is also very painful, children often wake up crying hard when bitten by one of these bugs, he said.
He explained that this comes after an acute or indeterminate phase lasting three to eight weeks, in which symptoms such as headache and muscle pains (myalgia), fatigue, loss of appetite and sometimes fever.
After this, between 10 and 30 percent of those affected will develop the chronic phase of the disease that progresses slowly and leads to damage and destruction of heart muscle, esophagus and large intestine, mainly.
Thus, this 10 to 30 percent of people who were bitten by the bug may develop dilated cardiomyopathy, which results in erratic operation of this important body and risk of death, or have difficulty swallowing food for the damage muscles in the esophagus, said the expert.
Still others said, will have problems in the large intestine are given a megacolon and this causes abdominal distention (swelling) and chronic constipation, among other discomforts.
On the other hand, he said, there are times when the bug even without itching , damage occurs, this happens when in contact with mucous membranes, especially at the level of the conjunctiva (eye) or in the mouth. He added that there are tools to diagnose the disease and it is best to grasp it in its acute phase, ie when it has not caused the damage on a gut level that is described here because they are irreversible.
A study of blood with very specific reagents can capture the presence of antibodies against the parasite and once confirmed the finding, which is applicable to drug treatment and is prescribed for two weeks.
