Elevation of the liver enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT) is common in acute dengue illness, occurring in 65–97% [2], [3], [4], [5] of dengue patients, peaking during the convalescent period of illness (days 7–10) [2], [4], [6]. This evidence concerns the gene GPT and dengue disease.
