Understanding The Cold Sore Virus

A cold sore, also known as herpes labialis, is a common viral infection caused by the herpes simplex virus (HSV-1).

This virus is highly contagious. Once infected, the virus tends to remain dormant within the body, and it can become reactivated under certain conditions, leading to the development of cold sores.

The herpes simplex virus is typically spread through direct contact with an infected individual.

This can occur through activities such as kissing, sharing utensils, or touching the affected area.

It’s important to note that the virus can also be spread through oral secretions, even in the absence of visible sores.

Effectiveness Of Dishwashers In Killing Viruses

One common query when it comes to preventing the spread of viruses is whether dishwashers are effective in eliminating them.

Let’s delve into the functioning of dishwashers in virus elimination and examine the scientific studies and research on dishwasher sanitation.
