Do all viruses make you sick.

Viruses are relatively simple in structure. They consist of one or more molecules. Are sometimes surrounded by a protein coat. The molecules contain the genetic material – i.e. the DNA or RNA – with the information for their multiplication. Unlike bacteria, viruses neither consist of their own cells nor do they have their own metabolism. They have no energy production of their own. No possibility of protein synthesis. Therefore, strictly speaking, they are not living beings.

Viruses are tiny, only about 20 to 300 nanometers in size. This is why they cannot be seen under an ordinary light microscope, but require an electron microscope. Viruses occur in many different forms. Some viruses look almost like tadpoles with a long tail, others are round or even rod-shaped.

Do all viruses make you sick?

Not all viruses in our environment affect humans. And not all viruses that infect humans actually make us sick. Because our immune system often reacts quickly. Fights the invaders with success. Nevertheless, there are important diseases that are caused by viruses.

Where do viruses occur?

Viruses invade animal, plant or human cells. They use these living cells as "host cells". They can also persist in the environment, sometimes for a very long time, and remain contagious. However, if they do not find a new host cell, they die sooner or later.

How do viruses multiply?

To multiply, viruses also need host cells. As soon as the pathogens enter our body – i.e. we are infected – the viruses begin to multiply. The virus attaches to the host cell. Lets it produce the building blocks it needs. Once the genetic material of the virus is released, the host cell is forced to produce numerous virus particles and assemble them into new viruses. The host cell then dies and thousands of viruses are released, which immediately start looking for a new host cell. Host cells can be red and white blood cells, but also liver cells, muscle cells and others. As long as we are ill, we continue to excrete the pathogens, often for some time afterwards.

What works against viruses?

It is not easy to fight viruses with medication. Antibiotics, for example, are ineffective against viral diseases. There are so-called antiviral drugs, but these only help against individual types of viruses. However, once our body's defenses have dealt with the pathogen, we are in many cases immune to the virus. We cannot then infect ourselves with the same pathogen a second time.

How do viruses ensure their survival? Viruses are flexible: the flu virus (influenza virus), for example, is constantly changing its face. Gets past the body's own defenses more easily this way. That is why the flu vaccine only protects us for one year, because by the time the next wave of influenza comes around, the transformation artist may have already changed its appearance again. The vaccine is adapted annually to the characteristics of the flu viruses that are currently on the way or expected.

What viral diseases are there?

Viruses can cause harmless illnesses such as a common cold or cold sores. Most of the gastrointestinal infections in this country are also caused by viruses. But serious infections such as HIV/AIDS or liver inflammation (hepatitis) are also triggered by viruses. Viruses also cause many of the so-called classic childhood diseases such as chickenpox, measles or rubella.
