What Causes Myositis?

Viral Infections

Any infection can cause myositis, but viral infections are significantly more likely to cause the disease. While fungal and bacterial infections have been the cause in past cases, these are rare experiences experts consider the exception to the rule. Viruses can sometimes invade the muscle tissue directly, damaging the muscles and leading to painful inflammation. Bacteria operates in much the same way. Even when a virus doesn't physically invade the muscles, it can still cause myositis. The virus releases substances that cause damage to muscle fibers, which in turn leads to inflammation. Human immunodeficiency virus (HIV) can cause myositis as just one of many symptoms as it attacks the body. Untreated HIV patients are also more vulnerable to inflammation and infection because of a weakened immune system. The flu and common cold are also capable of causing myositis. The effects of myositis tend to be more unpleasant than the original flu and cold symptoms.
