Microbes can spread and pass diseases in a number of ways:
1) By direct contact: physical contact (touching etc) with an infected person; sexually-transmitted diseases are passed on this way.
2) By indirect contact: touching something which an infected person has touched eg a towel, door knob, cup etc.
3) By inhalation: breathing in droplets containing microbes which have been produced by sneezing or coughing eg flu, TB, pneumonia.
4) By contaminated food or drink: eating food or drinking water which has been infected by microbes eg typhoid, cholera.
5) By animal vectors: animals can pass microbes on to humans by biting them eg fleas, mosquitoes.

A disease that cannot be spread from person to person is non-communicable. For example, lung cancer can make a person cough. But they won't give me cancer from coughing (though the cough can still spread viruses or bacteria). A person's Heart disease is not "catch-able".
The disease which is spread from person to person is called infectious disease. For example flu is a viral disease through which the other person is infected from the patient
