How long herpes simplex lives on dry surface?

The longevity of herpes simplex virus on dry surfaces depends on various factors, including the specific surface material, environmental conditions, and viral strain. While it can survive for certain periods, its infectivity gradually declines over time. Here's a general estimate:

Hard, non-porous surfaces (e.g., doorknobs, countertops, stainless steel): Up to several hours to a few days.

Soft, porous surfaces (e.g., clothing, carpets, tissues): Typically less than an hour, as the virus may get absorbed or trapped within the material.

In general, herpes simplex virus tends to be more stable on smooth, non-absorbent surfaces and in cooler, dry environments. Exposure to direct sunlight and hot temperatures can shorten its lifespan.

It's essential to practice good hygiene, including regular handwashing, to reduce the risk of transmission. Avoid touching your eyes, nose, and mouth with unwashed hands. If you suspect a surface may be contaminated with herpes simplex virus, it's advisable to disinfect it according to recommended guidelines.
