Discuss the routes of infection by describing the following events/phases that take place: ingestion, inhalation, cutaneous, genital, and injury
· Respiratory tract
– Another name for the common cold is an upper respiratory infection. It occurs when one of 200 different cold-causing viruses is breathed in and enters the respiratory tract into the lungs. Rhinoviruses are the most common of the viruses that cause colds. Coughs, influenza and other airborne infections are also contracted in this fashion.
· Breaks in the Skin
– One of the many functions of the skin is to act as a barrier against infection. However, if you have a bug bite, scratch or puncture wounds by needles, the germs that your skin is meant to keep out can enter your bloodstream. In addition, cuts, scrapes or sores in mucous membrane that lines the mouth or nose, provide a route for infection to enter. Common infections that start through the breaks in the skin are Cellutitis and Impetigo
· The Digestive Tract
– Food, drink or other infected products infection with bacteria or a virus can be swallowed and infect the stomach or bowels. Most people have experienced an upset stomach at one point in their life, which sometimes reveals itself in the form of diarrhea and/or vomiting. A common example of this is bacterial gastroenteritis, otherwise known as food poisoning. You can get food poisoning if you eat meat or poultry that came in contact with bacteria during processing; if your produce has touched water, during growing or shipping, that contained animal or human waste; or from improper food handling.
· Urinary and Reproductive Systems
– Pathogens can also enter the body through the urinary system, as is the case of a urinary tract infection, or the reproductive system, as is the case with sexually transmitted diseases. The infectious agent may remain localized or may enter the blood stream. For example, sexually transmitted diseases most commonly infect the genitals, which HIV, the AIDS virus, is carried in bodily fluids and can be transmitted in saliva, seminal fluid or blood.
