What does herpes simplex virus 1 typically look like?

Herpes simplex virus 1 is characterized by red, blister-like lesions that typically appear around the facial area, particularly near the lips and mouth. This presentation aligns with the nature of the virus, which is commonly associated with oral herpes outbreaks. These lesions often cluster together and can be painful or cause a burning sensation, which further supports the identification of option B as the correct answer. The visual aspect of red cluster blister-like lesions is indicative of the active viral infection and reflects the common symptoms experienced during an outbreak of this type of herpes.

In contrast, the other options describe symptoms that do not correspond with herpes simplex virus 1. Red lump lesions on the arms, itchy rashes on the torso, and yellow crusted scabs on the scalp are associated with different dermatological conditions or infections that do not share the typical characteristics of HSV-1. Therefore, understanding the visual presentation and common locations of lesions caused by the herpes simplex virus is crucial for correct identification.
