There are many diseases that are caused by microbes but not all diseases are caused by them, for example diseases like malaria, typhoid, cholera and AIDS are caused by microbes but diseases like diabetes, hypertension and many cancers are not caused by them at all.
Yes that’s true, not all the diseases in this world are caused by microbes. Diseases caused by microbes are their interactions with our body that are harmful to us. some of them are fatal and others can be controlled. Vaccines, Antibiotics and other chemical substances are to control disease.
