The herpes virus is one of the most prevalent viral diseases known to man. As much as eighty percent of all people, worldwide, have herpes simplex virus type 1 (HSV1), and twenty percent have herpes simplex virus type 2 (HSV2). This may sound like scary statistics, but most infected people suffer only mild discomfort. The more common form, HSV1, usually causes the occasional blister-like sores on or around the mouth. These blisters are called cold sores or fever blisters and, as most sufferers know, they are annoying and mildly painful but rarely dangerous. If the sores are left alone, they will generally heal up in five to twenty days. The less common version, HSV2, has the same symptoms except that the sores are usually found on or around the genitals. However, either type can be found in other places on the body and, in rare cases, the virus can cause serious problems. Ocular herpes (an infection of the eye) can cause blindness, and herpes encephalitis (an infection of the brain) can cause brain damage or death. We have no cure for the herpes virus at this time; once you have the virus, you have it for life. After the virus invades a new host, it incubates for two to twenty days. Then blister-like sores start to form, and in the initial breakout there can be fever, muscle aches and a general feeling of illness.
What is a virus?
Viruses are the smallest infectious agents known; too small to be seen with a normal microscope, an electron microscope is necessary to be able to see a virus. According to Oates, J.K. in Herpes: the facts (1983) " ... an average bacteria is roughly 1,000 nanometers in diameter, while viruses range in size from 300 to as little as 10 nanometers." and that " ... a human red blood cell, ... i...

With proper medical care, ocular herpes almost never results in blindness.
Shingles, herpes zoster, is a very contagious and painful rash, or blister that appears on the skin. These rashes most commonly appear on the sides of the body in stripes. The stripes are made up of many very painful blisters caused by a certain type of virus. The varicella zoster, most commonly known as the chicken pox virus attacks the nerve roots in that area. The herpes zoster virus is in the herpes family, including HSV, herpes simple virus, which causes cold sores, fever blisters, and genital herpes. (WebMD, 2011) Most people are required to get the chicken pox shot when they are children although some do not. The chicken pox shot helps to keep out the virus by keeping it dormant in the nerves. The varicella zoster virus stays in a few cells; this is how shingles appear suddenly. It appears when the dormant cells become active in the later years of life.

Bloodborne pathogens are viruses that deteriorate cells within the body. A virus is a submicroscopic parasitic organism that feeds on cells. Viruses are dependent on cells for their nutrients so the virus survive and reproduce. Every virus consists of either deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). A virus can contain a strand of one or the other, but not both. This RNA or DNA is contained within a protein shell for protection. A virus is a parasite that is dependent upon cells for metabolic and reproductive requirements. By using the cell the virus makes the host very ill by redirecting cellular activity to make more viruses.
Herpes. Herpes, a word that all of us know, something that gets made fun of by the raunchiest of comedians, a suggestion of a loose life style, a complex virus that was only recently seen as something to be feared since the early 1970’s for a target of money for pharmaceutical companies. Yet as common to be referenced by Shakespeare in Romeo and Juliet, and is a virus that is known worldwide, and almost every one has experienced in one-way or another.
Conclusion. Herpes simplex is a virus that many people contract in their childhood. It can cause lesions to form on the mouth or genitals that are both painful and irritating. Majority of the time, they only cause discomfort to the host. However, in rare scenarios, it can be life threatening.
Viruses are the simplest and tiniest of microbes, and are made up of proteins, nucleic acid, and lipids. The nucleic acids contain the genetic code that helps them grow and reproduce, but only once they find their way into a living organism. Viruses themselves are not considered living organisms because they don’t have cells, they don’t metabolize nutrients, produce and excrete wastes, and they can’t move around on their own. The remains of the nucleic acid then forms a covering, called the capsid. Once the capsid gets removed, viruses use the building materials of th...
This is an information packet about Non-Curable Sexually Transmitted Diseases (STD’s). There are several types of non-curable Sexually Transmitted Diseases: genital herpes, genital warts, hepatitis B, HIV and AIDS. Genital herpes is an infection caused by HSV-1 and HSV -2. (Describe HSV-1 and HSV 2) You can get genital herpes by having sex with someone that has it. Genital herpes can be spread by having oral sex, vaginal sex, or anal sex. It can also be spread by touching the infected area of someone that has it. Genital herpes is known to cause small painful sores or blisters. The sores can come and go, but once you have the virus you will always have it in your body. “The primary difference between the two viral types is in where they typically establish latency in the body- their "site of preference." HSV-1 usually establishes latency in the trigeminal ganglion, a collection of nerve cells near the ear. From there, it tends to recur on the lower lip or face. HSV-2 usually sets up residence in the sacral ganglion at the base of the spine. From there, it recurs in the genital area .
Hepatitis is the inflammation or swelling of the liver. The inflammation can happen from different injuries or viral forms of a disease. People who experience hepatitis have the symptoms of malaise, nausea, vomiting, loss of appetite, fever and jaundice. There are six known forms of Hepatitis which are Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E and Hepatitis G. The presence of hepatitis in the body can be very risky and cause severe death if not taken care of. Hepatitis is a severe issue that affect many people around the world like third world countries and cross contamination can occur mainly in health care places due to the exposure of patients with the disease and accidents handling blood or instruments, Hepatitis A,B,C,D,E and G are distinct diseases that differ in transmission and vaccines to prevent them or cure them.
Pathogens are a type of microorganism that spreads viral and bacterial diseases. These diseases when present in human blood and body fluids are known as blood borne pathogens, and can spread from one person to another. (Worcester polytechnic institute) The most serious types of blood borne diseases are the hepatitis B virus (HBV) and hepatitis C virus (HCV), which can cause liver damage; and HIV (human immunodeficiency virus), which is responsible for causing AIDS (acquired immune deficiency syndrome). The blood borne pathogens can be spread when the blood or body fluids (semen, vaginal fluid, breast milk, and amniotic fluid) of an infected individual comes into contact with mucous membranes or an open sore or cut on the skin of another person. Mucus membranes are located in the eyes, nose, mouth, and other areas as well. ("Bloodborne pathogens: MedlinePlus Medical Encyclopedia") Two of the most common ways that pathogens are transmitted is through the exchange of fluids during sexual intercourse or by sharing infected IV needles. (Worcester polytechnic institute)
The HBV virus is transmitted through contact with contaminated blood or other body fluids such as serum, semen and salvia. The condition following the infection can either be classified as acute or chronic HBV.

Sexually Transmitted Diseases Sexually Transmitted Diseases STDs, a.k.a venereal diseases, infectious diseases passed from one person to another during sexual contact. STDs are the most common infections known. More than 12 million people in the United States, including 3 million teenagers, are infected with STDs every year. The United States has the highest STD rate in the world about one in ten Americans will contract an STD during his or her lifetime. People who do not know they are infected risk infecting their sexual partners and, in some cases, their unborn children. If left untreated, these diseases may cause pain or may destroy a woman's ability to have children. Some STDs can be cured with a single dose of antibiotics, but AIDS cannot be cured. Those most at risk for contracting STDs are people who have unprotected sex—without using a condom, people who have multiple partners, and people whose sex partners are drug users who share needles. Static’s show that Americans between the ages of 16 and 24 are most likely of catching STDs than older adults, because younger people usually have multiple sexual partners than an older person in a long-term relationship. Teenagers may be embarrassed to tell their sexual partners they are infected Teenagers may also be embarrassed or unable to seek medical attention for STDs. This means that they only more likely to pass the disease to other young people and have a greater risk of suffering the long-term consequences of untreated STDs. STDs are transmitted by infectious bacteria, viruses, parasites, fungi, and single-celled organisms called protozoa that live in warm, moist parts of the body, like the genital area, mouth, and throat. Most STDs are spread while having sex, but oral sex can also spread disease. Some STDs are passed from a mother to her child while pregnant, when the disease enters the baby's bloodstream, during childbirth as the baby passes through the birth canal, or after birth, when the baby drinks infected breast milk. AIDS can be transmitted by blood contact such as open wounds, between people who share infected needles or received through an injection of infected blood. Some people believe that STDs can be transmitted through shaking hands or other casual contact, or through contact with inanimate objects such as clothing or toilet seats, but they can’t. Chlamydeous, is from trachoma is bacterium, is the most commonly transmitted STD in the United States.
According to the CDC, Center for Disease Control, during the first 48 hours symptoms like fever, headache, drowsiness, and could be apparent before the rash. The red, burning, itchy dots could appear all of the body including the arms, legs, head, chest, belly, and inside genitals. Blisters that are filled with clear fluid and ulcers can develop from the sores. The sores and blisters will eventually dry up and turn into scabs. The amount of spots on a person can differ per case; some have extreme amounts of blisters all of their bodies, while others barely have blisters. Warm conditions tend to irritate the rash more. The disease is easy to recognize because its main sign is rash. It is rare to get a lab for diagnosis for chicken pox although the varciella zoster virus can be diagnosed by a blood test that detects the antibodies for the
