What Is a Brain Infection?
3. Herpes Simplex Virus
The herpes simplex virus is also common, and most people will have been exposed to it at some point. There are two main types of HSV: HSV1 and HSV2. HSV1 is well known for causing oral herpes, and cold sores, and it is a highly contagious disease. It is usually harmless and will pass without treatment, although the symptoms of oral herpes can keep on returning.
HSV2 is the cause of genital herpes, which is a sexually transmitted disease. As with the oral variety, the symptoms of herpes are likely to come and go. The symptoms can be unpleasant, but are not usually serious. The herpes simplex virus can cause serious infections in some cases, however, including brain infections.
