Question

The herpes simplex virus type 1 (HSV-1), which produces a cold sore (fever blister), has an incubation period of

a) 2 to12 days.
b) 0 to 3 months.
c) 20 to 30 days.
d) 3 to 6 months.

Answer 1

The incubation period for herpes simplex virus type 1 (HSV-1), which causes cold sores, is 2 to 12 days. The virus remains latent in the body and can reactivate, leading to recurrent sores even after initial symptoms resolve.

Step-by-step explanation:

The incubation period for herpes simplex virus type 1 (HSV-1), which produces cold sores or fever blisters, is a) 2 to 12 days. HSV-1 is highly contagious and is known for its ability to become latent for long periods, residing in the trigeminal nerve ganglia between recurring symptoms. The virus may be reactivated by triggers such as stress or environmental conditions, leading to the development of lesions. These sores can spread through direct contact and may occur repeatedly due to the virus's persistent presence in the body despite resolution of the visible lesions.
