What is the primary cause of herpes simplex type 1?

The primary cause of herpes simplex type 1 is its highly contagious nature, particularly its transmission through direct contact with lesions. This virus is commonly contracted when an individual comes into contact with an active sore of an infected person, usually through kissing or sharing personal items like utensils or lip balm. The lesions can be present during an outbreak, which makes them a direct source of the virus.

While there are other modes of transmission, such as respiratory droplets and contaminated surfaces, they are not the primary means through which herpes simplex type 1 spreads. Airborne transmission is also not a typical route for this virus. Understanding that herpes simplex type 1 is primarily spread through direct contact with infected lesions is crucial for prevention and management strategies in athletic training and other contexts.
