Discuss The Common Sources Of Infection

Nosocomial infections refers to infections acquired during hospitalization, with symptoms usually occurring within forty-eight hours after admission.

Poor hand hygiene - spread of germs from one patient to another or spread for hands to surfaces.

The sources of infection can be divided in two main groups. These are exogeneous and endogeneous sources. A source of the infection is

A virus is a capsule containing genetic material, even smaller than bacteria. The main task of virus is to reproduce. However, viruses need a suitable host to

Common sources of infection include food, water, sick people (colds and flu or winter vomiting virus), animals and poor housing

Provide some examples of sources of infection for novel diseases, including the mode of transmission for WNV. Why is this concern?

In this assignment I am going to explain how infections are caused by, bacteria, viruses, fungi and parasites. I will then explain how pathogenic microorganisms grow and spread.

Food production led to the causes of many things, some such as germs carried by farmers usually, technology, and literacy. Infections and diseases were led by various animals, being around them or being involved with them caused this. Some of the major diseases we get as humans are smallpox, tuberculosis, flu, plague, measles, malaria, and cholera. These are evolved and mainly gotten from animals, usually animals like house pets or farm animals, since humans interact with them more than other kinds of animals. Germs and microbes pass through victims and spread around fairly simple or not simple at all. Usually, the easiest way for a germ to spread is through waiting to be passed to another victim. As if someone who is “sick” is contagious and

Respiratory (airborne infections breathed in), digestive (within foods/ drinks), blood circulation (via broken skin/ wounds), body fluids (sexually transmitted diseases, cross contamination, poor hygiene).

The spread of infection requires three elements. The first is; A source of infecting microorganisms: This could be an exogenous infection which arises from microorganisms external to the individual and do not exist as normal flora. They usually have a preferred portal of entry like the gastrointestinal for Salmonella. Another source is endogenous infections which can occur when part of the client’s flora becomes altered and an overgrowth results e.g. Yeasts infection. Second requirement is means of transmission for the microorganism, which also explains the three primary modes of pathogen transmission. For example, vertical transmission is when a pathogen is

Answer: Innate immune system or nonspecific resistance is also known as first line of defense. It’s nonspecific that means not design to target any specific microorganisms. Response time for innate immune system is very quick compare to adaptive immune system. These infections inhibited by the substance that change the humoral or cellular component of the host that mediated non specific resistance. They are not specific means they provide protection against a spectrum of organism. And they are vitamin, minerals, fatty acid and microbial product. These substances are major part of our diet. We consume food and get from it. Diet has both

infection, it is important that we ventilate settings by opening windows slightly. It is also important

Kissing, sneezing, sharing/ touching an object, such as a doorknob, soon after an infected person, you might be exposed to infection. Transmission occurs when you touch your mouth, nose, or eyes before thoroughly washing your hands. Germs can also be spread through contaminated blood products, medical supplies or sexual

The serological surveys revealed that about 60-80% of animals older than one year are seropositive to BVDV. The seropositivity may be attributed to the using of BVDV vaccines or the existence of PI animals (Baker 1995).

Chance plays a role in all infectious diseases. A person could be in the wrong place at the wrong time. What happens after depends on the amount of host factors. All infectious diseases start at the surface of the host. The only exception is certain intrauterine transmitted infections. The initial barrier is the skin, respiratory tract, or the gastrointestinal tract. The specific surface involved relates to how the microorganism reaches the host.
