Prevention of infectious diseases
We know about „black death” from historical sources. Modern scientists believe that this is a plague – a deadly disease caused by bacteria. In the fourteenth century, they were not able to heal it, besides, we did not observe the hygiene rules known to us today, which is why the disease easily spread. That is why an epidemicepidemic happened, that is mass infections of a large number of people. No wonder that the word epidemic is still scary.
Today, thanks to the achievements of medicine, many diseases are no longer as dangerous as they used to be. You can protect yourself against a lot. Prevention of diseases is called prophylaxis.
How to prevent infections?
One of the ways to prevent infectious diseases is vaccinesvaccines. They consist in the introduction of dead microorganisms into the body. Their presence does not harm the body, which at the same time learns to defend against them. In the case of invasion of living microorganisms, defensive mechanisms will already exist within the body. Some vaccines need only be given once to prevent a disease lasting a lifetime. Other vaccinations, for example against tetanus or tuberculosis, need to be repeated if you want to remain immune. Vaccinations against tetanus, rubella, measles and mumps are obligatory and must be given to every child. Thanks to vaccinations, these diseases are much rarer in our country. Others, for example against influenza, are voluntary – you can buy them in a pharmacy and take them after being examined by a doctor. After vaccination, antibodiesantibodies appear in your blood. They stay in the blood for a long time and destroy pathogenic microorganisms if they get into the body again.
Other ways to prevent infection are:
observing the rules of personal hygiene,
avoiding contact with sick people (including hugs, drinking from one cup),
strengthening the body's immunity through a healthy lifestyle,
avoiding the consumption of meats not subjected to veterinary or inspection controls.
What if you get sick?
But what to do when an infection occurs? Diseases can spread easily – so we have to limit it. Remember to always sneeze or cough in a handkerchief or on the arm above the elbow – never on your hands. A sick person should avoid contact with healthy people. This will protect our loved ones from getting sick.
Remember that you should regularly ventilate the room in which the person is staying, even in cold weather. Research shows that this way of cleaning the air is much better than air conditioning and strengthens the natural resistance to disease.
Summary
We should prevent infectious diseases and their spread.
One of the most important ways to prevent infectious diseases is preventive vaccination.
Mass infections with infectious diseases are called epidemics.
