Infectious Diseases

Infectious diseases are illnesses caused by microscopic organisms which can be spread from person to person or from animal to human. They can be mild and resolve quickly, or can be severe and can even be life-threatening. Taking preventative steps such as proper hygiene, immunizations, and getting timely medical care can help reduce the risk and spread of infectious diseases. Infectious diseases can have a significant impact on global health and public safety, and have been responsible for major epidemics in the past. They are an important factor in the global burden of disease, thus understanding and addressing infectious diseases is important for public health and safety.
