Smallpox is caused by the variola virus and is a contagious disfiguring and often deadly disease that has no existing cure or treatment. It was eradicated worldwide in 1980 by a global immunization campaign. Samples of the virus has been kept for research purposes.
Smallpox can spread several ways:
1. It can be spread by direct contact with an infected person after prolonged face-to-face contact or through the air by droplets that escape the infected person when the person coughs, sneezes or talks.
2. It can also be spread indirectly from the infected person. The virus becomes airborne and can possible spread through the ventilation system in a building.
3. From contaminated items such as clothing and bedding.
4. Potentially as a terrorist

It can also be spread by couching or breathing in the virus particles that come from the blisters. Persons who have shingles can also spread the virus to those who have not been vaccinated or who have never had the virus. Symptoms include a rash that itches which turns into fluid filled blisters and eventually into scabs. Fever, tiredness, loss of appetite, and a headache can also be present. The symptoms can last 5 to 10 days. Nursing interventions is to educate parents on the importance of immunizations and to provide calamine lotion to the infected patient to help relieve itching. http://www.cdc.gov/chickenpox/about/prevention-treatment.html Candidias is a fungal infection caused by yeast belonging to the Candida genus. Candida morally lives on skin without causing infection but an overgrowth of the organism can cause symptoms to develop. Symptoms vary depending on the area of the body …show more content…
Pediculosis are spread from person to person by close physical contact or through fomites such as combs, clothes, hats, and linen. Nursing interventions are to administer medications as prescribed and bag clothing to prevent the spreading of the Pediculosis. http://emedicine.medscape.com/article/225013-overview Neonatal Gonorrheal Ophthalmia is an infection of a newborns eyes caused by gonorrhea. It is passed to the newborn from the infected mother during a vaginal delivery. It causes swollen eyes or a yellow/green discharge from the eyes. If left untreated it can cause blindness. Gonorrhea is a common sexually transmitted disease and often does not have symptoms which make it hard to diagnosis. Nursing interventions include early screening of expecting mothers and teaching infected mothers the importance of taking the full dose of prescribed medication. http://www.eyedoctorguide.com/childrens_eyecare/neonatal-gonorrheal-ophthalmia.htmlons. Conjuctivitis, also known as “pink eye”, is an infection of the thin layer of the eye that covers the inside of eyelid and the white of the eye. It can be caused by a viruses, bacteria and
According to the Centers for Disease Control and Prevention (2013), MRSA is easily transmitted from person to person or from touching materials or surfaces that had previous contact with the infection. Using the implementation of infection control along with patient education will help in the decrease of the spread and help in the prevention in MRSA as well as get patients involved in their own care. The purpose of this paper is to present the problem of MRSA as well as include the rationale and history, review the proposed solution, integrate an implementation plan, summarize the literature review, establish an implementation plan, use a nursing theory to support the implementation plan, use a change theory to support the implementation plan, discuss how the project will be evaluated, and create a dissemination
There are two tests that doctors can use to detect gonorrhea, urine test or a swab of the affected area. The urine test can identify a disease, even when there are no signs or symptoms displayed. There is a swab test of the affected area, sometimes there are multiple test done to detect which sexually transmitted disease is present, home testing is available. When you have a home test done it is sent off to a lab to get analyzed and identify what is present. Gonorrhea is treated by several kinds of antibiotics, which are ceftriaxone, azithromycin, and doxycycline. The treatment is used for people who have tested positive for gonorrhea or somebody that had intercourse with someone that was diagnosed. When newborns are treated for gonorrhea, they are given medication in their eye. To prevent gonorrhea from returning don’t have sexual intercourse with someone that has or had gonorrhea until they get tested and it comes back
In order to understand the history of smallpox one first has to understand how diseases like it evolve. Much like other species, diseases that survive in the long run are the microbes that most effectively reproduce and are able to find suitable places to live. For a microbe to effectively reproduce, it must "be defined mathematically as the number of new infected per each original patient." This number will largely depend on how long each victim is able to spread the virus to other victims (Diamond, 198).
There is little at face value that would alert an educated individual to the severity and the danger of Syphilis – the bacterium which causes syphilis, Treponema pallidum, appears as nothing more than a simple bacterium. The bacterium is spiral in shape, and is classified as Gram Negative (meaning that the bacterium lacks a thick layer of peptidoglycan in its cell wall). Syphilis infects it's victims through a limited number of ways – the most common way, however, is by entrance through chafed, cracked skin and through mucous membranes. Because of this, Syphilis is so effectively transmitted through sexual contact and sexual activity that it is primarily known as a Sexually Transmitted Infection (STI). However, Syphilis does not limit itself to only the aforementioned modes of transportation. The disease is also effectively transmitted through blood transfusions, not to mention the passing of Syphilis from mother to child in the womb during pregnancy (CDC 2007).
the animals and cattle as well. The disease was so contagious that touching even an object that had
It began with infection mainly in the blood vessels of the human skin and mouth, resulting in different kinds of symptoms that turn into serious stages. It was spread by physical contact with human skin and mostly affected children and adults. This disease was so outrageous that it led to a vast number of deaths in New England colonies. Also, smallpox virus is transmitted through airborne infection from the oral, nasal mucus of the infected person. But mostly was spread from close contact or contaminated material of the infected person.
...or children. The specific way of transmission is difficult to identify. Most common assumptions have been that transmission has occurred through skin lesions or by sharing blood contaminated objects. Infected saliva is another source of infection especially as a non-parental infection. The virus has the ability to enter a healthy body as an airborne disease by coughing and sneezing, from mouth-to-mouth kissing, biting or by sharing chewed toys and candies [2, airborn]
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.
Many signs include a "white pupil," also known as leukocoria. Retinoblastoma can occur in either one or two eyes (Paul T. Finger, Pg. 1). This abnormal white pupillary reflex is sometimes referred to as a cat's eye reflex. Another sign of retinoblastoma is a crossed eye (Ambramson, Ch3). Leukocoria doesn't always end up as being retinoblastoma, it can even result in: congenital cataract, Toxocara canis, Coat's disease, and persistent hypertrophic primary vitreous (PHPV) (Finger, Pg.2). Retinoblastoma occurs when there's a mutation or deletion of the q14 band of chromosome 13 (Finger, Pg. 1). Symptoms can be painful if not treated quickly. Some include a red, painful eye, swelling of the surrounding eye, poor vision, dilated pupil, even extra fingers or toes, and retardation (Ambramson, Ch3).

Viruses can be transmitted in many ways. Being in contact with an infected person will most likely transfer the virus. One can also obtain the virus through swallowing, inhaling, and unsafe sex. Poor hygiene and eating habits usually increase the risk of catching a viral infection. Contracting a viral infection is followed by adverse s...
The virus cannot be transmitted directly from person to person, with that being said if a person does become infected there is no treatment for the virus. Now efforts to reduce pain and lower the fever are taken but the medications used for it have to be chosen carefully because some may increase a bleeding risk. Some of the symptoms of this virus are an abdomen and muscle pain; the whole body get the chills, fatigue, fever begins, or may have an loss of appetite; it’ll cause bleeding, delirium, headaches, nausea, vomiting, and the main reason it’s called ‘Yellow’ Fever because it may turn your skin or eyes yellow.
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.
Gonorrhea is a sexually transmitted disease (STD) that can infect both men and women and it can cause infections in the genitals, rectum, and throat (CDC, 2014). It is a very common infection, especially among young people between the ages of 15-24 (CDC, 2014). Gonorrhea can cause very serious complications when not treated, but can be cured with the right medication (CDC, 2014). Women with gonorrhea usually do not have symptoms and even if a woman develops symptoms, they are often mild and can be mistaken for a bladder or vaginal infection (CDC, 2014). Women who have gonorrhea are at risk of developing serious complications from the infection, even if they do not have symptoms (CDC, 2014). Men may also show no symptoms even if
