An illness resulting from pathogens is called infectious disease of contagious disease, these infectious diseases are something from which everyone should be aware because they are contagious and anybody could receive the bacteria through direct contact. The infections include viruses, bacteria, fungi, protozoa and other parasites. These infections can be transmitted in many ways such as physical contact, through contaminated food, touching contaminated objects and through inhaling such virus because these are also airborne. As mentioned above these are also contagious and can be transmitted if an infected person gets into contact with others, these can also be transmitted through intercourse, and however they do not require quarantine. In quarantine diseases the spread of the disease is believed to be quite dangerous therefore the infected person has to be in complete isolation so that it does not get transmitted. The quarantine is not only applicable to humans but also animals.
There are different kinds of transmissions such as respiratory diseases and meningitis can be transmitted through sneezing, coughing, talking, kissing and even singing. Gastrointestinal diseases can be infected by ingesting contaminated food or water whereas sexually transmitted infectious disease can be acquired if the person gets into contact with bodily fluids mostly through sexual activity. Getting into contact with a contaminated object which is also known as fomite can also transmit the disease. Diseases can also be transmitted through a vector, vectors pick up an infection from outside the body and transmit it, an example for this can be a housefly which can sit on dirt and then contaminate food and water by sitting on the rim of the glass or sitting on food. If it is the fly in question then the virus never enters the body of the fly, vectors are of two kinds biological and mechanical, and the former example was of a mechanical vector whereas a biological vector enter the body and deliver the virus. These viruses can be malaria, encephalitis, Lyme disease and African sleeping sickness. These biological vectors can be mosquitoes, ticks, fleas and lice.
Those want to work in infectious disease units then they must start with practical experience by working in health clinics so that they can encounter patients that have serious infections such as AIDS and HIV, these patients can be found in huge numbers therefore they are a great way to start practicing on them as they can gain a lot of experience by working in this particular department where people with such infectious diseases reside.
