your still well within the normal range on both and yes any type of infection, virus such as colds, flu even injuries that cause your white blood cells to increase will impact both the alt and ast numbers, both enzymes are highly sensitive to fluctuations in other bodily functions in addition fever in and of itself will generally drive the number up as to will any medications you may have taken such as cold medicines.
