4. Chickenpox
Chickenpox is also known as the varicella-zoster virus, and most people are vaccinated against chickenpox in childhood. According to the CDC, some people are still susceptible to the chickenpox virus even if they have been vaccinated against it. And, even if you have been vaccinated against the disease, you can still act as a carrier and pass it on to someone else even if you don’t show any of the symptoms yourself. There are an unlucky few people who can even get chickenpox more than once.
While it’s not a direct cause for cellulitis, people with chickenpox will be at a higher risk of developing cellulitis due to their compromised immunity, especially if they are children or the elderly.
One of the most common pieces of advice for people suffering from chickenpox is that they do not scratch their skin. Scratching can expose the skin to further infection, which can, in turn, cause cellulitis to develop.
