Answer:
A few harmful microbes, for example less than 1% of bacteria, can invade our body (the host) and make us ill. Microbes cause infectious diseases such as flu and measles.
There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease. Different diseases are caused by different types of micro-organisms. Microbes that cause disease are called pathogens.
It is important to remember that:
A pathogen is a micro-organism that has the potential to cause disease.
An infection is the invasion and multiplication of pathogenic microbes in an individual or population.
Disease is when the infection causes damage to the individual’s vital functions or systems.
An infection does not always result in disease!
To cause an infection, microbes must enter our bodies. The site at which they enter is known as the portal of entry from the host.
