The presence of pathogen doesn’t mean that an infection will occur. We can assume each element of the process represents a separate “link” to the chain of infection. The ‘portal of exit’ is the means by which the germ can escape from the reservoir. Thoroughly washing your hands is one of the easiest ways you can break the chain.

Non-human portals of exit for germs include items of equipment that haven’t been properly cleaned, such as commodes, bed mattresses, pillows and reusable equipment. If any of the links in the chain are missing then an infectious disease is unlikely to be transmitted to a new person. The ‘place’ can be a person – a patient/client or a member of staff – but it can also be any part of the surrounding area of a health care setting, furnishings in the patient’s/client’s room and the equipment we use in health care.

An individual’s genetic makeup may either increase or decrease susceptibility. For TB, it’s Mycobacterium tuberculosis. Specific immunity refers to protective antibodies that are directed against a s… Direct transmission occurs when there is direct contact with the infectious agent that leads to different diseases. For example, persons with sickle cell trait seem to be at least partially protected from a particular type of malaria. The first and most important link in the chain of infection is the infectious agent or pathogen which can be: The ability of any pathogen to thrive depends on three factors: A reservoir is the principal habitat (host) where a pathogen lives, flourishes and reproduces. This means that the germs that have been moved from the reservoir now invade the person (the ‘host’). Acute clinical cases are more likely to be diagnosed and treated which means that the patient's contacts and normal activities will normally be restricted.

When the bacteria invade the body, they produce a poison (toxin) that causes painful This means that even if some harmful germs enter the body, the person can ‘fight them off’ and stay well. The way to stop germs from spreading is by interrupting the chain. The final link in the chain of infection is a susceptible host. The portal of entry is the ability of infectious agents to enter the reservoir. Portals of entry into the human body include: The last link in the chain of infection is the susceptible host. In this ‘sequence’, all elements must be present for an infection to occur. The portal can vary from one infection to another (for example diarrhoeal infections are usually passed on via the patient's faeces).Germs can even be spread around on the tiny flecks of skin that peel off our bodies throughout the day and which form part of the dust that settles on all kinds of surfaces.

If we manage to break this cycle, and sever any one part of the chain, we can successfully prevent the spread of infection. This happens as a result of a sequence of events that take place between the infectious agents, the host and the environment – in a process known as the ‘chain of infection’.

In humans, there are two forms of reservoir: acute clinical cases (in which someone is infected and is displaying signs and symptoms of the disease), and carriers (where someone has been colonised with an infectious agent but is not unwell). This is how the germs move, or spread, from one place to another. / Chaîne d'infection. A health care worker comes along and touches the commode, and some of the germs move onto her hands. 3.
