Genital Herpes is a viral disease that is common in the United States. It’s casual agent is the herpes simplex virus type 2 but it can also be caused by herpes simplex type 1. “Humans and animals serve as reservoirs for herpes simplex but only humans demonstrate signs of the disease.”(http://www.austincc.edu/microbio/2704w/hsv1.htm) Genital herpes is mainly transmitted through any sexual activity where the genitals from both partners meet or through oral sex, when a person’s mouth comes in contact with with their partner’s infected genital. Herpes simplex has been around for thousands of years. It was first documented and named by the people of Greece. Herpes means to “creep,” which is exactly how the sores would spread from one location to another. It was in 1873 when Emile Vidal, first came to the realization that the herpes simplex virus can be transmitted from human contact with one another. Between the 1920’s and the 1930’s was when more studies started to occur on the herpes simplex virus and the discovery was made that HSV is a latent virus. Knowing this information, in 1940 ...
According to Medline Plus, the herpes simplex virus, also known as HSV, causes the infection known as Herpes. There are two types of HSV; there is Oral herpes that causes cold sores around the mouth or face and Oral herpes, or HSV 1, usually causes cold sores, however it is quite easy to transmit this disease to the genital area and can cause genital herpes. There is also HSV 2 and that is the usual cause of genital herpes, and like HSV 1, HSV 2 can infect the mouth. HSV 2 is also known as genital herpes and can affects the anal, buttocks or genital areas. This is a sexually transmitted disease, however there are other herpes infections that can affect the eyes, skin, or other parts of the body. Herpes can be dangerous in newborn babies or in individuals with weak immune systems.
Herpes Simplex is a common virus that causes infection in humans. This virus is spread in both humans and animals. However, humans are the primary reservoirs for HSV and are the only ones that experience any symptoms. There are two types of Herpes Simplex known as HSV-1 and HSV-2. HSV-1 primarily causes oral herpes while HSV-2 causes genital herpes.1 This virus is easily contracted and often during one’s childhood. Unfortunately, this virus is latent and reoccurs every so often, more so during times of stress. Herpes Simplex is a mild infection for most, however, this virus can lead to many serious complications.
There are over 100 types of HPV (Human Papilloma Virus). This virus affects the skin and moist membranes that line the body such as the mouth, throat, fingers, nails, cervix, and anus. Between 30 and 40 of the 100 viruses can affect the genital area; for the most part it causes genital warts. Human Papilloma Virus is one of the most common sexually transmitted diseases In the United States, according to various studies it is estimated that at least 50% of sexually active people will get some type of genital Hpv at some time in their lives. People can get Hpv and have the virus for years, even pass it on to their sex partners without even knowing it that is because the virus often does not show any symptoms. It is a sexually transmitted disease that can cause genital warts and cervical cancer”. (“HPV fact sheet” 2012).
Hansen’s Disease also known as Leprosy dates back to at least 4000b.c. Evidence of the disease’s presents in ancient times was found on an Egyptian papyrus dating from around 1500bc. These earlier cultures believed it was a curse or punishment from the gods. During the middle ages, the afflicted wore special clothing and rang bells to alert the uninfected of their presence. The first known origin of this disease is Egypt from here Roman Crusaders contracted the disease and brought it back to Europe and from Europe to America.
they don’t understand that type-1 herpes starts around the lips and the mouth. This still leaves them at the risk of getting the herpes virus, which leads to type-2 herpes virus also known as genital herpes.
As an undergraduate student the one word that you don’t want to hear from the doctors during a check-up or from a significant other is the word “syphilis”. This is like social suicide in addition to the obvious health issues and pictures that come to mind when hearing about this STD. A term that we have come to hear and to an extent be frightened of ever since that one crazy sex-education teacher ,back in high school, told you it was basically a death sentence if you were to catch it. Now though it’s not necessarily a death sentence it definitely is not your average chicken pox. So what exactly does this have to do with pathology? Everything! Now let’s take a moment to mentally go back in time to the earliest record of this disease.
An estimated 242,251 Canadians, and 150 million people worldwide are chronically infected with the hepatitis C virus, and more than 350 000 people die every year from hepatitis C-related liver diseases.1 Hepatitis C can lead to other serious diseases, such as liver failure, death, etc. But without any vaccines available to prevent the contraction of the disease, it may be hard to avoid. Due to disease generally being asymptomatic many people are unaware that they have it, further spreading the disease because of a lack of prevention mechanisms. Hepatitis C when developed chronically can cause serious affects on the liver, which may even lead to death. With hepatitis C being such a serious disease, it is important that more people be tested for it so they can start treatment in the early stages of the disease, as well as be aware and informed, before it becomes a chronic infection leading to serious complications.
Smallpox is a disease from the variola virus. Smallpox has caused an estimated number of 300 million deaths in the 1900s alone. Smallpox is said to have been around since the ancient Egyptian times. The disease was eradicated in the late 20th century and two samples are still kept, one in U.S.A and one in Russia. Smallpox creates bumps and blisters all over the body and has been one of the most fatal epidemics the world has seen.
Syphilis is a sexually transmitted disease (STD) caused by Treponema pallidum pallidum. Syphilis can also be passed from mother to infant during pregnancy. Syphilis can cause massive damage to body if left untreated. Known as “the great imitator” because several of the symptoms of syphilis are similar to other diseases, making it hard to pinpoint Syphilis’ origin (what is syphilis). Scientists and other professionals have come up with multiple hypotheses for the suggested origin of syphilis. There are three hypotheses currently being discussed. The first hypothesis states that syphilis was always in the Old World and syphilis probably evolved during the early Paleolithic in Africa or the Near East. According to this hypothesis, syphilis was transported to the New World by Columbus. This hypothesis is known as the “Pre-Columbus” hypothesis. The second hypothesis states syphilis was only in the New World. Syphilis was brought back to the Old World by Columbus and his crew. Columbus and crew returned to Europe, and shortly after, there was an epidemic of syphilis. This hypothesis is known as the “Columbus” hypothesis. The third hypothesis states that syphilis was present in both the Old World and the New World. This hypothesis is known as the “Unitarian” hypothesis. Evidence for these hypotheses have been collected and will be used to decide which hypothesis is more likely true or if more than one hypothesis is needed to explain the origin of syphilis. It is very likely that syphilis, when it was not viral, travelled from the Old World to the New World with Natives of the Americas during the mass migration around 16-14 thousand years ago and later on, the syphilis bacteria became viral. Also, syphilis could have been present in the O...
Chronic viral hepatitis(CVH) is a chronic inflammatory reaction of the liver due to either hepatitis B (HBV), hepatitis c (HCV) or hepatitis d (HDV) , occurring over more than 3 to 6 months. Chronic viral hepatitis is the main cause of chronic liver disease, cirrhosis and hepato cellular cancer (Porth, p962). According to a media report on “the rising burden of chronic liver disease a high price to pay ";liver disease affects more than 6 million Australians and costs the government $50.7 annually. Marriott (2013) stated that chronic viral hepatitis is still referred to as the silent epidemic due to lack or low levels of risk awareness. The manifestations and changes that occur in the liver and treatment options will be further explored to provide awareness of the condition.
Childhood vaccinations have received a lot of media in the past few years, and parents continue to question whether or not they should have their children vaccinated. This topic is a very important issue because it seems to be a trend in our society where parents are not vaccinating their children. This then leads their children becoming more susceptible to unnecessary diseases/viruses that can be prevented with vaccines. The focus of the following articles was on the association of the specific vaccines measles, mumps, and rubella (MMR), and vaccines containing thimerosal, which has been a speculated reason for the cause of autism. This contentious hypothesis has many parents failing to vaccinate their children; this is especially true of many friends and family members of mine. They believe that vaccines can cause autism, and I want to prove otherwise.
This case reveals how many people are infected with the herpes simplex virus without knowing it, and how it can affect you in unusual ways. If the patient had been aware she was infected, if she had had a prior outbreak, perhaps the doctors may have been able to resolve her condition much sooner. But herpes simplex can be a “silent” virus, invading your body with no symptoms until low immunity, hormonal changes or stress activate the virus and cause symptoms. Unfortunately, doctors do not think to test for the herpes virus for this syndrome unless the patient has an active outbreak or history of herpes.
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.

Syphilis is a sexually transmitting infection caused by Treonema pallidum, a gram negative, and anaerobic spirochete bacteria 1. Syphilis is thought to have been brought to Europe by Columbus and his sailors in the 1500’s 1. The disease is characterized by four different stages with varying symptoms depending on the stage that the disease is in1. Often syphilis is presented with another sexually transmitted infection such as chlamydia. Public education regarding safe sex is important for the prevention of this sexually transmitted infection.
