that number is a short hand way of expressing a large number it is read as 1.9 times 10 to the 5th power (aka 10 times 10 times 10 times 10 times 10) so the number in the common numbering system is 190,000 IU/mL to that is how many copies of the virus circulating in your blood. For your comparison my viral load before my most recent treatment was 2.4 million IU/mL or 2,400,000 or 2.4 E+6 same number expressed in different ways.
Or you can Google scientific notation
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9.
But anyway viral load is on no significance except to confirm you are infected with hep c. Viral load has no correlation to severity of illness.
