Which two types of genital herpes simplex virus are recognized?

The two recognized types of genital herpes simplex virus are HSV-1 and HSV-2. HSV-1 is commonly associated with oral herpes, which can lead to cold sores or fever blisters around the mouth. However, it can also cause genital herpes through oral-genital contact. HSV-2 is primarily responsible for genital herpes and is mainly transmitted through sexual contact. Together, these two types represent the primary and most clinically relevant strains of the herpes simplex virus. Understanding the distinction between these types is crucial for diagnosis, treatment, and prevention strategies related to herpes infections.

The other options provided do not correspond to the recognized types of the herpes simplex virus, as HSV-3, HSV-4, HSV-5, and HSV-6 are not categorized under genital herpes. HSV-3 is known for causing chickenpox and shingles, while HSV-4, 5, and 6 are related to other viral infections and diseases.
