Microbes are constantly around us. They can be found in air, soil, water, and even in our own body. Some microbes are beneficial, while others - only harm. Secondly these harmful not so much.
Infection - this is when germs get inside us, began to multiply and caused a reaction in the body.
To start an infection, you need three things:
Source Victim (sensitive persons) and the transmission path.
A source
The hospital germs can sit on sick people, medical personnel and visitors.
People can get sick and spread germs. More people can be colonized by microbes. Then they will not get sick, but will spread the infection.
Inside the hospital germs can live not only in humans but also in the environment:
- On dry surfaces such as medical equipment and furniture;
- On wet surfaces and biofilms;
- At various catheters and tubes that are inserted into the sick person;
- The dry dust or dirt with a damp, somewhere near running water;
Victim
This perceptive person. It is not vaccinated, or he was not ill this infection and do not get stability. Maybe he has a weak immune system. The infection penetrates into it, will begin to multiply and cause some kind of reaction.
It happens that a strong immune system, but the infection enters the body in an unnatural way. For example, through intravenous catheter, urinary catheter or through an incision during surgery.
Increase the susceptibility to infection, some diseases and conditions:
- diabetes;
- crayfish;
- organ transplantation;
- antibiotics, corticosteroids, chemotherapy.
If you pre-calculate these risks, we can not allow the infection to attack humans.
transmission path
Microbes do not crawl and do not attack. They are attached to the person or the place where settled.
Inside hospitals microbes can move through direct contact (touch) via spray, or by air at different sections and punctures.
Contact It occurs when, for example, the health care worker touches the microbial source, and then, unable to process the hand touches a person's susceptibility.
Spray fly after coughing or sneezing. Usually spray fly no further than a couple of meters. If splashes get into the eyes, nose or mouth, the sensitive person can get sick. Thus transmitted, e.g., pertussis or meningitis.
by air Germs are transmitted after they flew together with small droplets and then dried droplets. Or if the microbes were living somewhere in the air. By Air contagion spreads further. So it can be transmitted tuberculosis or measles.
Through cuts and punctures transmitted HIV and viral hepatitis.
