BacteriaBacteria are microscopic single-celledorganisms that thrive in diverse environments. They can live within soil, inthe ocean and inside the human gut. Humans’ relationship with bacteria iscomplex. Sometimes they lend a helping hand, by curdling milk into yogurt, orhelping with our digestion. At other times they are destructive, causingdiseases like pneumonia and MRSA.Virus Viruses areeven smaller than bacteria and require living hosts.
Such as people, plants oranimals to multiply. Otherwise, they can’t survive. When a virus enters your body, it invades some of your cells and takes over the cellmachinery, redirecting it to produce the virus.FungiFungi are living organisms. They used to be grouped together with plantsbut they are distantly related. They are perhaps more closely related toanimals than to plants.
Fungi consist of molds, yeasts and mushrooms.ParasiteA parasite is an organism that lives in anotherorganism, called the host, and often harms it. It is dependent on itshost for survival – it has to be in the host to live, grow and multiply. Aparasite cannot live independently.

– Cryptosporidiosis.- Toxoplasmosis.1.3An infection means that germs are in oron the body and make you sick, which results in signs and symptoms such asfever, pus from a wound, a high white blood cell count, or pneumonia. Germs canalso be in or on the body, but not make you sick.
This is called colonization 1.4The difference between a systemicinfection and a localised infection. A systemic infection affects the bloodstream such as the flu or high blood pressure or a disease which affects theentire body.
Where as a localised infection is one particular part of the body.1.5Poor practices that could lead to aninfection would be poor infection control measures. Meaning that the PPEguidelines are not being followed appropriately.A poor practice for an example wouldbe not changing your gloves before attending to another patient or not washingyour hands before and after personal intervention or food handling.2Understand the transmission of infection2.
1Oxygen and moisture is required to encouragemicro-organisms to grow and survive.2.2An infectious agent can enter the bodythrough, airborne, through skin contact such as cut, wound. A infectious agentcould enter the body through the nose, mouth and eyes. Also through genitals ora insect bite or open spot. 2.
3Common sources of infections can be airborne,animals, people, surgical sites, people who are carriers, the environment.Objects, bodily fluids such as blood, urine, faeces, sexually transmitted orskin contact.2.4 Infectious agents are transmitted to a personfrom sharing towels, touching objects soon after a infection person has touchedthem.Examples could be using a ward telephoneafter an infected person has used it with their hand after not washing themfrom doing personal care. Another way could be sneezing on the key board of acomputer then you typing on the keyboard and then rubbing your eyes.2.5Key factors that will promote infections tooccur would be not washing hands before and after interaction with infectionperson.
Not cleaning the environment and objects thoroughly and regularly. Notfollowing COSHH procedures and using correct cleaning products. Not adhering toPPE policy’s.
