Summary of the Nine Types of Herpes Infections Found in Humans
1 . Herpes simplex virus Kind 1 (HSV-1)
Fever blisters plus cold sores of the face, mouth area, and lips are the most common symptoms of HSV-1 outbreaks. Also known as Human Herpes Virus-1 (HHV-1).
Surprisingly, most infections with this virus occur by two years of age via breaks in the pores and skin barrier around the mouth or somewhere else on the body. While HSV-1 is usually thought of as the cold sore virus plus HSV-2 (see below) is thought of as the genital herpes virus, distinctions between them often fail. It is well noted in the medical literature, although not yet widely publicized, that the virus launched from a cold sore can easily transfer through oral-genital contact to establish a genital herpes infection in another person.
Besides causing cold sores and possibly spreading to the genital region, HSV-1 has also been linked with the development of serious nerve diseases such as Alzheimer’s disease, Bell’s palsy and trigeminal neuralgia. Recent research also shows that co-infection simply by HSV-1 and HIV (human immunodeficiency virus) can enhance the activity of each viruses in patients who have AIDS and non-genital herpes lesions.
HSV-1 infects at least 50% of people worldwide.
2 . Herpes simplex virus Type 2 (HSV-2)
Also called Human Herpes Virus-2 (HHV-2). This type is the usual cause of genital herpes, which is classified as a std. HSV-2 reached epidemic status in the 1980s and 1990s, mostly due to its increased incidence among teenagers. In the world of virus classification, HSV-2 and HSV-1 are nearly indistinguishable except for their various clinical symptoms. However , even these types of differences are inconsistent, since both types of herpes simplex can cause oral and genital herpes outbreaks.
three or more. Herpes zoster virus (HZV)
Also called Varicella zoster virus (VZV) and Individual Herpes Virus-3 (HHV-3).

Chickenpox results from a first time infection by HZV. When this virus recurs later in the person’s life, it causes shingles. As the average age of our population increases, more and more people are suffering repeating bouts of post herpetic neuralgia (nerve pain) as a result of shingles. This particular herpes virus is considered to be the most infectious of the known herpes viruses. More than 90% of the population is infected.
HZV has been linked to the autoimmune disease called lupus. Furthermore, HZV breakouts, which are now epidemic among individuals with AIDS, are often the earliest indicator of HIV infection.
4. Epstein-Barr malware (EBV)
Also called Human Herpes Virus-4 (HHV-4). The major cause of infectious mononucleosis (“kissing disease”), EBV may also be the primary culprit in causing Chronic Fatigue Syndrome and other disorders of the defense mechanisms. EBV has also been linked with lupus, lymphomas, and other cancers. This virus is currently considered to be quite damaging and mutagenic (causes genetic mutations) in the body.
About 75% of the population will test positive for EBV.
5. Cytomegalovirus (CMV)
Also called Human Herpes Virus-5 (HHV-5). CMV can cause mononucleosis and hepatitis and it can also be sexually carried. Recent research suggests that CMV includes a role, in conjunction with other types of infections, in turning on cancer genetics.
The occurrence of CMV will be strongly correlated with vascular diseases like coronary artery disease and atherosclerosis. Even though it is generally asymptomatic, CMV may turn out to be a key factor in the development and progression of heart plus blood vessel disease, one of the top killers in all developed nations.
CMV infects about 60% of grown ups, but is even more common amongst homosexual men and is associated with AIDS.
6. Human Herpes Virus-6
7. Human Herpes Virus-7
8. Human Herpes Virus-8
9. Human Herpes Virus-9
(HHV-6, HHV-7, HHV-8, plus HHV-9, respectively)
All HHVs are usually associated with disorders of the immune system, especially AIDS. HHV-8 is also called Kaposi’s sarcoma associated human herpes virus (KSHV), which causes a type of skin cancer that develops most often in people with AIDS.
The particular recent discovery of new HHVs that individuals with AIDS suggests that there are a lot more herpes viruses to be discovered. Certainly, new types of these herpes viruses are probably evolving every year. HHV-6 and HHV-7, both found in about 90% of the population, are two closely related viruses that are relatively brand new discoveries and are considered to be “universal” herpes virus viruses.
Infection with HHV-6 throughout childhood causes “roseola infantum, inch a. k. a. “sixth illness. ” HHV-6 has recently been associated with the development of multiple sclerosis.
