The figures provided by the WHO claim that 66.6% of the world’s population is infected with herpes simplex type HSV-1, which commonly causes cold sores.

Genital herpes is much more difficult to handle. To cope with the initial outbreak, you may need to take a 2 mg dosage per day for up to 10 days. With the recurrent episodes, the therapy typically lasts for 3 days with a 1 mg daily dosage split into two intakes.
