What is this article about?

Shingles (also known as herpes zoster) is a viral infection caused by a reactivation of the varicella-zoster virus (VZV) that causes chickenpox (varicella). When someone first becomes infected with VZV, they will contract chickenpox. However, after chickenpox resolves, the virus will stay dormant in the dorsal root ganglia (nerve cells in the spine) and may reactivate later on in life. For this reason, only people who have had chickenpox are at risk of shingles. Shingles presents as a painful, blistering rash. The reactivated virus generally affects one or two adjacent dermatomes, which are areas of skin that are mostly supplied by a single nerve root branching out from the spinal cord.

Infection control is very important reminder at the work place because it can help to prevent of spreading the differntvkinds of infections like shingles or viruses. At the aged care facilities most elderly have low immune systems that can easily infected the virus. With proper knowledge of how to handle the infections properly it will help to let the elderly be infected.

Sometimes I find it really hard to make time for my learning, but I was blown away by how easy it is with the Ausmed app. I can fit it in during breaks or on the bus to work.
