* Infectious diseases are known as communicable diseases or contagious diseases or transmissible diseases. These diseases results from infection, this infection may come from pathogenic biological agents in an individual or host organism.
* It is caused by pathogens that include viruses,bacteria,fungi,protozoa,multicellular parasites and aberrant proteins.That means without pathogens no infectious epidemic can occur.
* The transmission of pathogens can occur through physical contact and contaminated food,body fluids,objects,airborne inhalation or through vector organisms.These diseases can transmit through contact of an ill person or their secretion,thus called contagious.
* Infectious disease results from the interplay between those few pathogens and the defenses of the host or individual they infect.
* The transmission of the infectious diseases may occur through several different mechanisms. Aerosolized droplets,spread by sneezing,talking,coughing or even singing can cause respiratory diseases and meningitis.
* Contaminated food and water can cause gastrointestinal diseases.Vector transmission is also a cause.These vectors may be mechanical or biological.Housefly is an example of mechanical vector. It contaminates its appendages with bacteria from feces and leaves them on the food prior to consumption.
* The best way to prevent or slowdown the transmission is to recognize the characteristics.Enough precaution must be taken in the epidemic.
* Infection from most of the pathogens does not result in death,it requires immune mechanisms to kill or inactivate the pathogen. Antibodies and Lymphocytes must be taken to acquire immunity.
* The network of the health departments must be expended,the information exchange is important to avoid hazards.Health departments must share their informative notes about each other's progress and researches.The risk factors must be identified quickly.
* Training about infectious diseases epidemiology must be provided across the world so that all the nations can get the benefit.Education about the disease and awareness on the international level is important.

There are number of diseases those are transmitted through contact.It seems very difficult to take control over infectious diseases as these are originating continuously but prevention is the safest measure.By making use of predictive models the hazards can be reduced.Infectious diseases 3d animation and infectious diseases 3d medical illustrations are extremely beneficial in knowing more about the problem as they provide knowledge in an entertaining mode.
