Infectious Diseases Specialist
An infectious disease is a condition that typically occurs from an external bacteria or virus that invades the body. These external elements are called pathogens and can also cause ailments in other species and animals. Since the pathogens can be passed on from the afflicted person to another, these are also called communicable diseases or contiguous diseases. There are various ways in which these transmittable diseases can be passed on from one individual to another. These include touch, water, air and food. Sometimes an understanding of how a disease transmits can help in actually treating the disease and also in stopping the spread of the problem to other people. For example, if you know that conjuntivitus is caused by touch, it is possible to maintain a distance from those who have the condition so as not to contract the disease. Some pathogens that are transmitted through air are therefore more difficult to control. Spread of diseases cause by them is more rampant.
It also depends on the longevity and survivability of the pathogen in specific conditions that causes the spread or halt of a communicable disease. With vaccinations that have been developed over the years, the pathogens also mutate in a manner that new strains of pathogens develop, creating a scenario where we today have various emerging infectious diseases that we have never seen before. The issue has reached such alarming extent that we now have transmittable disease specialist who continue to research the various strains of specific bacteria and viruses.
New infectious diseases can occur due to a combination of mutations that may occur. Predicting these mutations and understanding the strains of viruses that can surface in the future is difficult. The infectious diseases list is extremely long since a large number of conditions actually arise from external pathogens that invade the human body. While a large amount has been done on transmittable diseases that are known, there is little research that has been done conclusively on the kind of issues that the world is likely to face in the future. This is not to say that there is no research that is happening today on these issues but the fact that the scope is extremely large and requires billions of dollars for funding.
New communicable diseases sometimes tend to cerate a panic in the population. This is mainly because of the fact that people are not aware of the specific symptoms, causes and treatment options available. In most cases a new condition is detected only after a few cases have bee discovered and caused havoc. The lack of predictability of the manner in which these pathogens shall develop caused alarm among people when something like this occurs. However, an infectious disease there is also work being done to reduce the time that it takes in developing a new vaccination.
