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.

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.
