Describe the disease caused by herpes simplex 1 virus (HSV-1) as well as how it is spread. Based on the disease characteristics, is HSV-1 capable of lysogeny?
What will be an ideal response?
Answer: The incubation time of HSV-1 is short (3-5 days) and the virus primarily infects epithelial cells around the mouth and lips, causing cold sores that heal without any treatment in 2-3 weeks. HSV-1 can be acquired either through direct contact or through saliva. After initial infection, HSV can become lysogenic in the nervous system, entering a lytic cycle periodically. The conditions that result in the virus becoming lytic are not well understood, but seem to be related to stress and immune system function.
