Document Summary
Genital tract acquired there, shed in genital secretions. Mucosal events during transmission every body surface is covered by epithelium, squamous or. This layer protects from pathogens infectious agents must transverse this. Ulcer caused by herpes ulcers in mucosa, then virus can pass the layer. Dc sign receptor gp120 binds to dc sign. Receptor identifies sugar molecules on pathogens gp120 covered with sugar get into dendritic cell. Three types of general patterns found in viral infections. Amount of virus present in host over time. Herpes initial infection; infection cleared but virus able to enter certain cell poplations that prevents them from immune attack. Type 3 initial infection; infection partially controlled by virus continues to replicate; Viruses that cause type 1 often more damaging to tissues than viruses of type 2 and 3. If damaing to tissues and type 3 virus then hos probably will die.
