VIRAL INFECTIOUS DISEASE
What is viral infectious disease? Generally, viral infectious disease is contagious disease cause by the virus. Wide range of virus will cause viral infectious disease. Viral infectious disease had a very big impact on the practice of dentistry as viruses can spread easily in various routes of transmission, highly contagious and many prevention need to be taken in providing treatment to patient with viral infectious disease. Some of the famous and notable viruses will be in the family herpexviridae, paramyxoviridae, adenoviridae and retroviridae. However, in here, we will only focus on Acquired Immunodeficiency Syndrome (AIDS).
Etiology Agent
Acquired Immunodeficiency Syndrome or AIDS is cause by Human Immunodeficiency Virus (HIV) of genus lentivirus which is one part of the retroviridae family. There are two types of HIV which had been identified, HIV-1 and HIV-2. Shape and structure of HIV is roughly spherical with diameter of 1/100000 of a millimeter. HIV had a viral envelope which coats the external surface of the virus.

Tuberculosis or TB is an airborn infection caused by inhaled droplets that contain mycobacterium tuberculosis. When infected, the body will initiate a cell-mediated hypersensitivity response which leads to formation of lesion or cavity and positive reaction to tuberculin skin test (Kaufman, 2011). People who have been infected with mycobacteria will have a positive skin test, but only ones who have active TB will show signs and symtoms. Basic signs and symptoms include low grade fever, cough with hemoptysis, and tachypnea. They may also show pleuristic chest pain, dyspnea, progressive weight loss, fatigue and malaise (Porth, 2011).
Acquired Immune Deficiency Syndrome (AIDS) was first recognized as a new disease in 1981 when increasing numbers of young homosexual men succumbed to unusual opportunistic infections and rare malignancies (Gallant49).During this time, many people were contacting this disease because it was not discovered yet and people did not have knowledge about it.Scientists believe HIV came from a particular kind of chimpanzee in Western Africa. Humans contracted this disease when they hunted and ate infected animals. A first clue came in 1986 when a morphologically similar but antigenically distinct virus was found to cause AIDS in patients in western Africa (Goosby24). During this time, scientists had more evidence to support their claim about this disease. Once discovered this disease was identified as a cause of what has since become one of the most devastating infectious diseases to have emerged in recent history (Goosby101). This disease was deadly because it was similar to the Black Death, it was killing majority of the population. Since its first identification almost three decades ago, the pandemic form of HIV-1 has infected at least 60 million people and caused more than 25 million deaths ...
Candida albicans is a harmless commensal yeast which becomes pathogenic when environmental changes trigger the virulence factors of the organism. Hence Candida species are opportunistic pathogens in susceptible individuals. Oral infection caused by C. albicans known as oral candidiasis or candidosis. However, C. albicans exist in the mouths of 80% of healthy individuals. Any alteration in the environment of oral cavity can change the presence of candida from commensal to pathogenic. This translation in the status of candida is due to many predisposing factors. In the past, oral candidiasis was thought to affect mainly elderly and very young population. Recently, the incidence of oral candidiasis increased greatly with the intensification of HIV infection and immunosuppressive chemotherapy (1, 2). Oral candidiasis colonize 5% to 7% of newborn less than one month old. The infection also estimated to affect 9% to 31% of AIDS patients and nearly 20% of cancer patients (3). This review discuss the possible causes, the types of oral candidiasis, treatment and management strategies.
In conclusion, it is important for the dental staff to treat all patients as if they are infected. A patient may or may not choose to disclose any information pertaining to their disease or they may not be aware of it. It is also important for the dental staff to have immunizations done at regular intervals. The hygienist needs to make sure he or she protects him or herself as well as the patient during treatment. Discrimination against someone with a disease is illegal. With that in mind it is the clinician’s duty to be aware of diseases he or she may come into contact with and how to treat the patient.
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.
As you exit the bus, another passenger next to you starts to cough, and then you hold the handrail as you exit the bus. Since you’re late getting home, you take a shortcut through a field to get home quicker. These three simple acts just exposed you to bacteria, viruses, and insects that could cause illness or even death. Infectious diseases, also known as communicable disease, are spread by germs. Germs are living things that are found in the air, in the soil, and in water. You can be exposed to germs in many ways, including touching, eating, drinking or breathing something that contains a germ. Animal and insect bites can also spread germs.1
Human immunodeficiency virus (HIV) is a retro virus that causes AIDS. HIV is a virus that can only be contracted between human to human. HIV weakens your immune system because this virus is destroying cells that fight diseases and infection in your body. A virus can only produce itself by taking over a cell in the body of its h...
In 1665, in the Kingdom of England, there was a great disease going through the kingdom that killed over 100,000 people, it was passed throughout the population by tiny bugs that were everywhere and were nearly impossible to avoid. This epidemic is known as the Great Plague of London, 1665 and it is the strand of the Bubonic Plague that tore through London, killing about 15% of London’s population which was around 100,000 people. This Plague was one of the worst diseases to tear through Europe in the 1300’s - the 1600’s. It hit England especially hard because they were on an island and had to where to go and couldn't avoid the spreading of the disease.
Infection control is a central concept to every practice of health care providers. Its main objective is to prevent the transmission of infectious diseases from both patients and health personnel (Martin et al., 2010). In dental clinic, infection control is a continuous concern for its professionals. They have to contact patients routinely and be exposed to their blood, saliva, dental plaque and pus that may contain infectious pathogens. It is important for the dental professionals to treat these fluids as if they are infectious and special precautions must be taken to handle them. In this essay, I will highlight the scope of infection control practices in dental clinics and the ways through which infectious microorganisms are transmitted in the dental clinic. Also, I will talk about some infection control guidelines implemented in dental clinics and how they meet the needs of the patients. Finally, from a personal perspective, I will mention some factors that affect the implantation of infection control guidelines and procedures.
Infectious diseases also called as communicable diseases are caused by pathogenic microorganisms (such as bacteria, viruses, parasites or fungi), can be spread directly or indirectly from one person to another.
Infection control, a term that describes procedures taken to reduce the spread of infection. The dental office is a place where many people are treated including patients with infectious disease such as tuberculosis, HIV/AIDS, hepatitis, and many other highly contagious diseases. It is imperative that in any dental office setting the prevention of the spreading microorganisms from patient to patient, patient to staff, or staff to patient is done in high precaution. Infection control has two main objectives; to protect the patients from harmful pathogens as well as dental team members. Infections can cause or add pain, deteriorate a persons health, and in worst cases even result in death. In order to understand the infection control in a dental facility, you must understand the standard precautions required by organizations that regulate or recommend infection control, the kinds of preventive measures taken, as well as when these measures should be taken.
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.
I have researched this topic through various sources and compiled pertinent information to provide adequate information on this. topic. The sym First of all, AIDS is caused by the retrovirus HIV. HIV stands for human immunodef- iciency virus. AIDS itself stands for acquired immune deficiency.
