Cordial welcome from Science Access to participants, from all around the world to attend the 2nd World Congress on Infectious Diseases (Infectious Diseases-2019) during March 4-6, 2019 in London, UK. Theme of the conference includes “Research Advances of Infectious Diseases and Strategies for Prevention”. Science Access (SA) is initiated to meet a need or to pursue collective goals of the scientific community, especially in exchanging the ideas which facilitate growth of research and development. Microorganisms like viruses, bacteria, parasites and fungi are cause Infectious diseases. The diseases can be spread, directly or indirectly, from one person to another. Zoonotic diseases are infectious diseases of animals that can cause disease when transmitted to humans. Microorganisms that cause disease are collectively called pathogens, which cause disease either by distracting the bodies & stimulating the immune system to produce a protective response, resulting in high inflammation, fever and other symptoms. Infectious diseases can be spread from one person to another, for example through contact with bodily fluids, by aerosols (through coughing and sneezing), or via a vector, for example a mosquito. Infectious diseases are one of the leading causes of worldwide deaths.
