Overview of nine herpes viruses found by humans
1. Herpes simplex virus type 1 [HSV-1]
Facial blisters and cold sores on the face, mouth and lips are the most common symptoms of HSV-1 outbreaks. Also known as human herpesvirus-1 [HHV-1].
Surprisingly, most infections of this virus occur at the age of two and rupture through the skin barrier around the mouth or other parts of the body. Although HSV-1 is considered a herpes simplex virus and HSV-2 [see below] is considered a genital herpes virus, the distinction between them often fails. There is a lot of literature in the medical literature that, although not publicly available, viruses released from cold sores are easily transferred through oral-genital contact to establish a genital herpes infection in another person.
In addition to causing cold sores and possibly spreading to the genital area, HSV-1 is also associated with the development of severe neurological diseases such as Alzheimer's disease, Bell's palsy and trigeminal neuralgia. Recent studies have also shown that co-infection with HSV-1 and HIV [human immunodeficiency virus] can enhance the activity of both viruses in patients with AIDS and non-genital herpes lesions.
HSV-1 infects at least 50% of the world's population.
2. Herpes simplex virus type 2 [HSV-2]
Also known as human herpesvirus-2 [HHV-2]. This type is a common cause of genital herpes, which is classified as a sexually transmitted disease. HSV-2 reached its prevalence in the 1980s and 1990s, mainly because of its increased incidence among adolescents. In the field of virus classification, HSV-2 and HSV-1 are almost indistinguishable except for different clinical symptoms. However, even these differences are inconsistent because both types of herpes simplex can cause an outbreak of oral and genital herpes.
3. Herpes zoster virus [HZV]
Also known as varicella zoster virus [VZV] and human herpesvirus-3 [HHV-3]. Chickenpox is caused by the first infection with HZV. When the virus reappears later in a person's life, it causes plastic surgery. As the average age of our population increases, more and more people suffer from herpes zoster and postherpetic neuralgia [neuralgia]. This herpes virus is considered to be the most infectious virus of the known herpes virus. More than 90% of the population is infected.
HZV is associated with an autoimmune disease called lupus. In addition, the current HZV outbreak of AIDS patients is usually the earliest indicator of HIV infection.
4. Epstein - Barr Virus [EBV]
Also known as human herpesvirus-4 [HHV-4]. The main cause of infectious mononucleosis ["kissing disease"], EBV may also be the leading cause of chronic fatigue syndrome and other immune system diseases. EBV is also associated with lupus, lymphoma and other cancers. It is now believed that this virus is highly destructive and mutagenic in the body [resulting in genetic mutations].
About 75% of the population will be tested positive for EBV.
5. Cytomegalovirus [CMV]
Also known as human herpesvirus-5 [HHV-5]. CMV can cause mononucleosis and hepatitis, and may also be a sexually transmitted disease. Recent studies have shown that CMV works with other types of viruses to turn on cancer genes.
The occurrence of CMV is closely related to vascular diseases such as coronary artery disease and atherosclerosis. Even though it is usually asymptomatic, CMV may be a key factor in the development and progression of heart and vascular disease, one of the leading killers in all developed countries.
CMV affects approximately 60% of adults, but is even more common among homosexual men and is associated with AIDS.
6. Human herpesvirus-6
7. Human herpesvirus-7
8. Human herpesvirus-8
9. Human herpesvirus-9
[HHV-6, HHV-7, HHV-8 and HHV-9, respectively]
All HHVs are associated with diseases of the immune system, especially AIDS. HHV-8, also known as Kaposi's sarcoma-associated human herpesvirus [KSHV], causes a skin cancer that is most common in AIDS patients.
A new HHV has recently been discovered in AIDS patients, indicating that more herpesviruses have been found. In fact, these new types of herpesviruses may develop every year. HHV-6 and HHV-7, found in approximately 90% of the population, are two closely related viruses that are relatively new discoveries and are considered "universal" herpesviruses.
Infection with HHV-6 during childhood can lead to "baby rose rash", also known as "sixth disease." HHV-6 has recently been associated with the development of multiple sclerosis.
