Which type of herpes simplex virus usually produces genital infections?

Herpes simplex virus type 2 is primarily associated with genital infections. This virus typically leads to the development of painful blisters and ulcers in the genital and anal areas. The transmission usually occurs during sexual activity, making this a relevant factor in public health education concerning sexually transmitted infections.

While herpes simplex virus type 1 can cause oral herpes (cold sores) and occasionally lead to genital infections through oral-genital contact, it is predominantly known for affecting the mouth and lips. Types 3 and 4 do not typically contribute to genital infections, as they are associated with chickenpox (type 3) and Epstein-Barr virus (type 4), respectively. Therefore, the specificity of herpes simplex virus type 2 in causing genital infections makes it the correct answer.
