The causative agent of genital herpes, HSV-2, is enveloped. The biological significance of this viral envelope in the context of transmission is that it makes the virus:

A. Highly resistant to environmental desiccation and disinfectants
B. Highly susceptible to drying, requiring direct moist contact for transmission
✓
C. Capable of surviving on fomites for several weeks
D. Impervious to host antibodies

📝 Explanation

The correct option is Highly susceptible to drying, requiring direct moist contact for transmission. Enveloped viruses derive their lipid bilayer from host cell membranes. This envelope is fragile, making the virus susceptible to drying and detergents, thus requiring direct intimate contact for successful transmission.

📖 Additional Information

  • Highly resistant to environmental desiccation and disinfectants
  • Highly susceptible to drying, requiring direct moist contact for transmission
  • Capable of surviving on fomites for several weeks
  • Impervious to host antibodies

The correct option is Highly susceptible to drying, requiring direct moist contact for transmission. Enveloped viruses derive their lipid bilayer from host cell membranes.
