“Many countries, including the United States, Sweden and Germany, count an infant exhibiting any sign of life as alive, no matter the month of gestation or the size, but according to United States some other countries differ in these practices.
“All of the countries named adopted the WHO [World Health Organization] definitions in the late 1980s or early 1990s, which are used throughout the European Union.
“However, in 2009, the US CDC issued a report that stated that the American rates of infant mortality were affected by the United States’ high rates of premature babies compared to European countries.”
