An infection is when microorganisms infest and reproduce into an organism's body. The microorganisms feed and benefit from the host, which potentially harms them. Two infections are viral and bacterial.
Viral infections are caused by different kinds of viruses. They have a simple structure and are tinier than bacteria by a landslide. Viruses can only survive in a host, and are unable to reproduce by themselves, instead they use the host’s DNA to multiply and repair. Most viruses are harmful to the human body and cause disease. They direct themselves to infect the cells in the liver, respiratory system, and blood. Which cause diseases like the flu, chickenpox, Aids, herpes, etcetera. Viruses are also involved in many forms of cancer. They
Tesco is a UK based Supermarket Company which was founded in 1919 by Jack Cohen, since then it has grown to become a multinational company which specialises in a lot more than just groceries, this has improved the overall profit of the company. The overall employees recorded at the end of 2015 was 476,000+, this shows that is a source of employment for nearly half a million people in the UK. The supermarkets are no longer just in the UK they also have shops based in Malaysia, India and Poland, this presents that they are increasing the size of business to a multinational company and is also a good source of jobs for people in poorer countries. In the world over 75million people travels
Tesco’s objective is to be the ‘champion for customers’, and they want to achieve this by being number one in customer satisfaction. They want to grow globally and by doing this they ‘create value for customers to earn their lifetime loyalty’. Tesco is
The B cells, T cells, Macrophage, and Antibodies are all a very large part of the immune system. There are two types of T cells, killer and helper T cells. Killer T cells find and destroy cells infected with bacteria, and helper T cells control the activity of other cells in the immune system. Then, B cells are considered the “clean up crew,” attacking any bacteria or viruses the T cell left behind. They also make antibodies, which are essential for trapping invading viruses and
The anti-social behaviour act was made in 2003. The reason for why this was made was to make the rules of anti-social behaviour better and work more efficient also to do the same with the fixed penalty notices. The rules of this act is no one that is under the age of 16 is allowed to buy spray paint due to graffiti on private properties, no group of teenagers are allowed to do anything wrong to the public and also no public drunkenness which can lead to people disturbing the peace. An example for this could be the ASBO’s.
Standard 1 for the NAEYC professional preparation is “Promoting Child Development and Learning” With the key element “Knowing and understanding young children’s characteristics and needs” the artifact in which I choose is the activity plans with adaptions done in the How Children Learn class. In my opinion this activity allowed us to think further than a typical developing child. Adaptions were to be planned for children that are gifted, autistic, and ones that may have speech and language impairment. Being able to plan activities based on the child’s own needs and developmental range is why this artifact fits well with this key element.
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.
Approximately four babies are born every second of the day in the world, that means that means that there are roughly 345,600 people that have the exact same birthday, including the same birth year. That makes you wonder, what the chances are that a pair of people in a room have the same birthday. With the application of the birthday paradox, also known as the birthday problem, these “chances” can be approximated.
The objective of the host is to "escape" from the pathogen. This can be done through the use of the immune system or by quickly dying. When a host dies with the pathogen still inside the pathogen dies as well. Resistance to invaders evolved as a result of the development of the mechanism of immunity. The development of immunity depends on the recognition of differences in chemical structures of substances.
The job of the immune system is to keep “foreign” invaders out of the body, or if one gets in, to seek it out and kill it. These foreign invaders are called pathogens, which are tiny organisms that can cause an infection in the body. Pathogens can be bacteria, parasites, and fungi (http://www.niaid.nih.gov/topics/immuneSystem/pages/whatisimmunesystem.aspx).
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.

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).
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...
Virus- An infectious agent found in virtually all life forms, including humans, animals, plants, fungi, and bacteria. Viruses touch us every day through water, food, physical contact, blood, animals, or even, the air you breathe. Although most are harmless, there are some that are not.... ...
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.
Bacterial and viral infections have many things in common. Both types of infections are caused by microbes -- bacteria and viruses, respectively -- and spread by things such as:
