Is there any way that herpes type 1 is caused by food? how can I protect myself now?

Hi.

HSV-1 is primarily transmitted through direct contact with the herpes sores, saliva, or mucous membranes of an infected person. This often occurs through activities such as kissing, sharing utensils, or other forms of close personal contact. It's less commonly transmitted through objects, but it's still possible, especially if contact is made shortly after the infected person touches them.

There's no evidence to suggest that HSV-1 can be caused by food. However, sharing food or utensils with someone who has an active outbreak can be a mode of transmission. If your friend has an active cold sore, it's wise to avoid sharing utensils, glasses, or food.

1. Shared Household Items:

   • Toilets: HSV-1 is not typically transmitted through toilet seats. The virus does not live long on surfaces, especially not on non-mucosal surfaces like toilet seats.
   • Washing Machines: You can safely share a washing machine. HSV-1 does not survive well outside the human body, particularly in the environment of a washing machine with detergent and water.
   • Cutlery and Dishes: These can be a mode of transmission if shared immediately after use by an infected person, particularly during an active outbreak. It's advisable to wash dishes and cutlery thoroughly, which is generally sufficient to eliminate the virus.

2. Living with Someone with HSV-1:

   • Personal Hygiene: Maintain good hygiene practices, like washing hands regularly and not touching your face or mouth.
   • Avoid Direct Contact with Sores: Avoid direct contact with any active sores.
   • Awareness During Outbreaks: Your friend may be more contagious during an active outbreak (when cold sores are present), so extra precautions during these times are sensible.

HSV-1 is a common and manageable virus. Many people live with it without significant issues. Your friend may consider antiviral medications if outbreaks are frequent or severe.
