Name: Megan Dixon Causative Agent: Human Papillomaviruses Disease: plantar warts, genital warts, cervical cancer Classification of the causative agent: all HPV are non-enveloped double stranded DNA. History: More than half of sexually active adults become infected with HPV, it is that common. Virulence factors of the causative agent: HPV contain certain proteins, E6 and E7, that inactivate the host’s tumor suppressor proteins. Which ultimately result in the rapid dividing rate that can’t be regulated Mode of transmission: HPV is contracted through skin to skin contact. The most common way is through sexual intercourse. It is possible to contract the disease by merely shaking someone’s infected hand, but it is improbable. Incubation
... when “HPV inserted its DNA into the long arm of her eleventh chromosome and essentially turned off her P53 tumor suppressor gene” (Skloot 213). This allows the cancer cells to produce monstrously virulent cells, making them hard to kill.
(Attention Getter) The Center for Disease Control reports that 100% of sexually active men and women contract genital HPV
HSV-1 is spread through saliva and direct contact, such as kissing, sharing eating utensils, sharing drinks or sharing personal items. Children often contract the virus from kissing their parents and coming in contact with other children. HSV-2 is spread through sexual intercourse. HSV must be transported through bodily fluids (saliva, pus, semen, vaginal fluid) to infect cells.3 The virus is transmitted through the mucosal linings of the body or through an open wound and has an incubation period of 2-12 days.4
What is the human papillomavirus (HPV)? According to the US government’s National Cancer Institute, human papillomaviruses (HPVs) are a collection of more than one hundred viruses, many types having the ability to grow tumors or polyps that are malignant and others benign. Certain of the viruses are capable of forming genital warts. The HPVs that cause the common warts on hands and feet are different from those that cause growth in the throat or genital area (Human Papillomavirus). Professors Joe Cummins and Dr. Mae-Wan Ho inform us that some types are associated with cancer, and are called “high risk” HPVs. Of the more than one hundred types of HPVs, over thirty can be passed on through sexual contact. Most HPV infections occur without any symptoms and go away without treatment over the course of a few years. However, HPV infection sometimes persists for many years, with or without causing detectable cell abnormalities. Infection from “High risk” types of HPV is the main cause of cervical cancer. Pap smears have also led to earlier detection of these infections. Nearly all women who are sexually active will have HPV inf...
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).
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.

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.
Although this disease isnt to common there still has been some new research about this topic. About 400,000 people live with hemophilia each year while there are only about 20,000 people that live with it in America. About 400 babys are born with this disease each year in the U.S. Usually only males get this disease but it is possible for women to get it. Hemophilia is also caused by a genetic mutation. So as you can see Hemophilia is not to common.
All families should get their children vaccinated against the most common STD in America, the Human papilloma virus (HPV). As health care professionals it is essential to educate parents and adolescents about the HPV virus which can cause genital warts along with many varieties of cancers including cervical, penile and throat cancer. The vaccine will guard against four strains of the virus. Two of these strains are known to cause 70% of cervical cancer cases and the other two cause 90% of genital warts (Kara Newby, 2009). Another reason to receive the HPV vaccine is to promote sexual and reproductive health education. Two of the biggest arguments against the HPV vaccine are the high cost and that some parents feel it will make their teenagers feel invisible and may engage in more risky sexual behaviors if vaccinated.
Other ways hepatitis A can be transmitted from person to person are through direct contact with an infected person, such as sexual contact, and sharing of needles for intravenous drug use. Hepatitis A can also be transmitted by coming in contact with contaminated food or water. Also, foods that are uncooked or undercooked and have been contaminated with Hepatitis A can transmit the virus. Bennett, A. J.,2016; World Health Organization, 2017) Hepatitis A can affect a person of any age group.
Recent research shows that, there are three major means by which infections can be transmitted and they include direct transmission, indirect transmission and airborne transmission (Hinman,Wasserheit and Kamb,1995). Direct transmission occurs when the physical contact between an infected person and s susceptible person takes place (division of public health, 2011). An example is a health care worker who attends to an Ebola patient, without gloves, gown and mask plus forget to wash his or her hand with soap and hot water and or a person having flu without the use of mask or washes his hand after sneezing easily passes the infection to the other through hand shake or surface touch, living the bacteria there for another vulnerable person to also touch if the surface is not disinfected with bleach. Studies makes it clear that, the spreads takes effect when disease-causing microorganisms pass from the infected person to the healthy person through direct physical contact such as touching of blood, body fluids, contact with oral secretion, bites kissing, contact with body lesions and even sexual contact. However, measles and chicken pox are said to be conditions spread by direct
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.
