You can get them from the water, either swimming in it or drinking it.nswer 1: Both viruses and bacteria can enter the body different ways.

virus HIV can be transmitted in many ways, such as vaginal, oral sex, anal sex, blood transfusion, and contaminated hypodermic needles. Both the virus and the syndrome are often referred to together as HIV/AIDS. People with HIV have what is called HIV infection.

How Infection Works Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease, which typically happens in a small proportion of infected people, occurs when the cells in your body are damaged as a result of infection, and signs and symptoms of an illness appear.iruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system’s antibodies and other cells to target the invader.

Overview Infectious diseases are transmitted from person to person by direct or indirect contact. Certain types of viruses, bacteria, parasites, and fungi can all cause infectious disease. Malaria, measles, and respiratory illnesses are examples of infectious diseases.

Section 10: Chain of Infection Portal of entry. The portal of entry refers to the manner in which a pathogen enters a susceptible host. The portal of entry must provide access to tissues in which the pathogen can multiply or a toxin can act. Often, infectious agents use the same portal to enter a new host that they used to exit the source host.

Information on the different types of viruses and types of viral infections Types of Viral Infections. Viruses can affect any part of the body or body system, and can cause infections such as the common cold, flu, gastroenteritis, chicken pox or herpes. The most common type of viral infections involves the respiratory tract. viral infection is any type of infection that is caused by a virus, which is even smaller than bacteria and is encapsulated by a protective coating, so it is more difficult to kill than bacteria. Viral infections involve a dormant virus getting into a living cell and re-writing the cell's genetic codes with its own.

- They then travel up the urethra to the bladder. Sometimes, bacteria escape the bladder and urethra, traveling up the ureters to one or both kidneys. Pyelonephritis is a potentially serious kidney infection that can spread to the blood, causing severe illness.

- Once the virus or bacteria is in it can travel in the blood to any cell in your body. Once it reaches the cell of choice it can enter by tricking the cell into thinking it is food or using a entry way that nutrients, molecules and other proteins use to get in to the cell.

- 2. Genitourinary: This portal of exit is the route of sexually transmitted diseases, including syphilis, gonorrhea, chlamydia, and HIV. Schistosomiasis, a parasitic disease, and leptospirosis, a bacterial infection, are both spread through urine released into the environment.

Intracellular Infection by Salmonella Most bacteria can live inside the human body without causing any symptoms of disease. Bacteria that do cause disease are called pathogenic.. The invasion of the body by pathogenic bacteria is referred to as infection. Some types of bacteria, such as Salmonella and Listeria, live inside human cells.They are called intracellular pathogens.The ability of intracellular pathogens to hide inside the host cells shields them from the immune system.t present, we do not know how the bacteria escape from the host cell to infect other cells. Intracellular Infection by Salmonella Animation Background. Bacteria are small, single-celled organisms whose genetic material is not enclosed in a special nuclear membrane.

Routes of transmission Different pathogens have different modes of transmission. For example respiratory pathogens are usually airborne and intestinal pathogens are usually spread by water or food. The main routes of transmission are listed below. Person-to-person Touch

Germs: Understand and protect against bacteria, viruses and infection Infection, often the first step, occurs when bacteria, viruses or other microbes that cause disease enter your body and begin to multiply. Disease occurs when the cells in your body are damaged — as a result of the infection — and signs and symptoms of an illness appear.

Viral Infections Some viruses spread through the blood-stream or the nerves, attacking cells throughout the body. For instance, HIV, the human immunodeficiency virus that causes AIDS, attacks certain cells of the immune system that are located throughout the body.ost viruses do not cause serious diseases and are killed by the body's immune system—its network of natural defenses. In many cases, people never even know they have been infected. But unlike bacteria, which can be killed by antibiotics, most viruses are not affected by existing medicines.

How Long Can HIV Live Outside of the Body? 1 There must be a route of transmission, such as through certain sexual activities, shared needles, occupational exposure or transmission from mother to child. 2  There must be a means for the virus to reach vulnerable cells within your body, either through a rupture or penetration of the skin, absorption through vulnerable mucosal tissue, or both.

How infections get into the body? I would like to know all the ways that infections can get into the body (in as much detail as possible) I know the basics: food and water skin but anything else or more detail would be great thanks xxxx. Follow.hen harmful microbes, or germs, enter the body, they multiply and cause disease. This is called infection. Your body's defenses usually do a killer job of squelching harmful microbes. But sometimes germs multiply faster than the body can handle -- and you get sick.

Dropped frames/disconnecting/lag? Read this first! In some rare cases, dropped frames can be caused by an old network adapter driver doing a poor job of handing the high speeds being consumed. It's not a bad idea to just check to see if there are any new drivers for your network adapter, just to be sure.

Hepatitis B The virus is transmitted by exposure to infectious blood or body fluids. Infection around the time of birth or from contact with other people's blood during childhood is the most frequent method by which hepatitis B is acquired in areas where the disease is common. In areas where the disease is rare, intravenous drug use and sexual intercourse are the most frequent routes of infection.

- In most meningitis infections, bacteria or viruses spread through the blood. An infection can begin in one part of the body, such as your throat or lungs, before moving through the tissue and into the blood.
