Virus or bacteria, how to tell?

Virus or bacteria, how to tell?

Especially in autumn and winter seasons, the most common diseases are upper respiratory tract infections. To be able to define the causative agent of these infections can make the right diagnosis, make the necessary treatments and avoid unnecessary treatments. I want to talk about it, why the separation of viruses and bacteria is important.

Viruses are very tiny creatures that can only be seen with an electron microscope. They usually spread from person to person. In children, 80-90% of upper respiratory infections are caused by viruses. Viruses have no specific treatment (except chickenpox virus and influenza virus). The use of antibiotics in a virus-related disease is useless, in fact, it can do more harm than good because it can cause the reproduction of resistant bacteria.

How to remove the virus from the body? It is excreted by the body's immune system.
What is Bacteria? Bacteria are micro organisms that are many times larger than viruses of different types and are visible with light microscopy. Bacteria are the agents of upper respiratory tract infection much less frequently. Common bacterial infections - beta hemolytic streptococcus (throat infection), mycoplasma that infect the respiratory system, or bacteria that are secondary to viral infection.
Antibiotics against bacteria work (such as pneumonia after influenza infection), but since bacterial resistance is an important concept today, it is important to select antibiotics well and to use the correct and recommended dosage. The use of antibiotics under the supervision of a doctor is absolutely essential.

However, since most upper respiratory infections are virus-dependent, most will recover without antibiotics.
It has now been shown that most of the ear infections are due to viruses, and if the child is not high-fever and does not appear very ill, it is recommended to observe for at least two to three days without antibiotics.
Unfortunately, it is not always easy to identify the causative agent of the virus and the bacteria. However, with the care and patience of both physicians and parents, it is often possible to prevent misdiagnosis and unnecessary drug use. Parents' awareness about virus bacteria separation is also very important.
