Infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful. But under certain conditions, some organisms may cause disease. Examples of infectious diseases are Flu, Measles, Dengue, smallpox, tuberculosis, cholera, HIV and AIDS, Meningitis, Malaria, etc. The specialty of these emerging infections since the past century can be discussed at Infectious diseases conference 2020 which is scheduled in London, UK.
