Seroprevalence and maternal-fetal transmission rate in the Potosí health facilities.

<p>Seroprevalence and maternal-fetal transmission rate in the Potosí health facilities.</p

Maternal - Fetal transmission ratio and controls carried out on children less than one year of age born from positive mothers.

<p>The Maternal-Fetal transmission ratio is calculated with the total number of congenital Chagas cases per year, over the number of children born from positive mothers tested at birth. The ratio decreases as the number of annually tested children increases.</p

Total of pregnant women screened and seroprevalence 2004–2009.

<p>The 1^st phase includes the departments of Cochabamba, Tarija, and Chuquisaca, with a large seroprevalence in Chagas disease. The 2^nd phase additionally includes the departments of Santa Cruz, La Paz and Potosi, with a lower seroprevalence. The average prevalence decreases as the total of women screened increases in less endemic areas.</p

Cases diagnosed according to the method used and time of follow up.

<p><b>2004–2009.</b> Most of the congenital cases were diagnosed by micromethod before six months of age (micromethod at birth and micromethod control).</p

Follow up of children born from positive mothers between 2004 and 2009.

<p>Children tested at birth increased due to the inclusion of big maternities in the program; however, the number of children followed after birth, did not increase proportionally.</p

Pregnant women screened compared with pregnant women registered in health facilities and seroprevalence (2009).

<p>In the 6 endemic departments of Bolivia, the number of women tested is greater than the number of women registered in each hospital. This fact is due to numerous failures in clinical records that lead to repeat testing in prenatal controls.</p
