The Microbial Threat: Entering Human Hosts

Infectious diseases are a global hazard that put every nation at risk. Throughout history humans have struggled to control infectious diseases and we will continue to do so into the foreseeable future.  WIth scientific advances many diseases have been rendered obsolete. But dangerous bacteria adapts, evolves and continues to survive.

An Invisible Enemy

The increasingly interconnected world of international commerce and travel has made every nation susceptible to infectious diseases.  Microbial pathogens do not recognize geographic or political borders. They arrive without warning, constituting a grave threat to the health of humans. They can enter human hosts 4 ways:

Respiratory tract

MIcrobes gain entry to the respiratory tract by inhalation through the nose or mouth. This makes respiratory illnesses far more contagious than most.  Examples include the common cold, flu, and respiratory infections.   

Gastrointestinal Tract

Eating contaminated foods can provide entry for microbes to infect the gastrointestinal tract. Contaminated foods are often of animal origin, but all foods can become contaminated. An example of such a bacterial infection is salmonella, which attacks the intestines and causes severe gastrointestinal symptoms.

Urogenital Tract

Bacteria that infects the urogenital tracts most often cause urinary tract infections.  These are usually caused by bacteria from the intestinal flora. Eschericia coli causes about 70% of all infections, and Staphylococcus Saprophyticus causes about 10% of infections.

Breaks in Skin Surface

Cuts and other breaks in the skin provide access for bacteria to enter the body.  The staphylococcus bacteria is a type of germ commonly found on the skin or in the nose of even healthy individuals.  Most of the time these bacteria cause no problem to the host. But when there is a cut or abrasion, these bacteria invade deeper into your body. Staph can enter your bloodstream, joints, bones, lungs or heart.

Protecting Yourself From the Microbial Threat

Keep in mind that only around 1% of bacteria are harmful.  But we all know from experience how much damage that 1% can do! When you know how it thinks and the ways it invades, you can better protect yourself.  Hand washing, proper hygiene, treatment of wounds and other proactive measures will help significantly.  We can help you assess your risk of microbial exposure.  Contact us to talk to an expert today.
