The best known chronic infection involves Hepatitis B.

Here's why:

1. Chickenpox: While chickenpox is a highly contagious disease, it is not typically a chronic infection. Most people get chickenpox once in their lifetime and then become immune to it.

2. Herpes: Herpes is a chronic infection, but it's not the best known. There are two types of herpes simplex virus: HSV-1, which causes oral herpes (cold sores), and HSV-2, which causes genital herpes.

3. Hepatitis A: Hepatitis A is an acute infection, meaning it is short term. It does not become chronic.

4. Hepatitis B: Hepatitis B can become a chronic infection, meaning it lasts for six months or longer. It can lead to serious health issues, like cirrhosis or liver cancer. Hepatitis B is one of the most common chronic infectious diseases in the world, making it the best known among these options.
