Viral skin infections, such as shingles, can be painful and contagious. These infections not only cause discomfort but can also lead to serious health issues if left untreated. Shingles, caused by the varicella-zoster virus (the same virus that causes chickenpox), often result in a painful rash that can spread if not managed properly. Understanding how to prevent the spread of shingles and other viral skin infections is crucial for maintaining your health and the well-being of others around you.
