Viruses Attack Humans

Viruses attack humans

Introduction

As we learned in class, viruses are microscopic protein capsules that have at least one nucleic acid (DNA or RNA) and they do not have cells.

It is a particle much smaller than a bacterial cell, viruses enter the host cells and kidnap the enzymes and materials of these host cells to produce more copies of themselves, as the US author explains, they do not reproduce alone, to do so They use the genetic information of the cell they invade, inject their genetic material and multiply generating the death of the cell.

Developing

Viruses can attack from human beings to bacteria, but not all cause effect on systems of all species, since each virus can only infect one or a few of these. Some of these may be influenza or HIV.

Each virus is different and because of that, its form of infection varies. Some are transmitted through breathing, others by consuming food, also sexual (due to the exchange of body fluids) or by blood contact (such as a mosquito bite). In this way, each virus has a specific treatment, there are vaccines to prevent some of them and others have treatments to attack them; But at the same time, several do not have these tools, since virologists have not found the right ones, because not all are so easy to treat. Antibiotics are not effective against them, since these are designed to attack bacteria. 

The difference between a bacterium and a virus is that the first is a unicellular being that reproduces in a asexual way and the second as explained above, colonizes cells to multiply.

While some bacteria are beneficial, viruses are simply infectious.

Today, the world is facing a pandemic caused by the "COVID-19", better known as the Coronavirus, although generalizing, "Coronavirus" is a word that encompasses a family of these, which cause different diseases such as even A common cold. The COVID-19 has several theories of contagion and origin, but the main one is that it was originated in Wuhan, China due to bats, through zoological transmission. 

conclusion

At the same time there are investigations that claim that it was created in a laboratory in that city, but WHO explains that there is not enough evidence to support these hypotheses. To date there are 2,416,135 confirmed cases worldwide, since this virus is very easy to spread.

It still does not have a treatment, but if you are working in laboratories to achieve it and preventive measures have been taken at a global level. To avoid these viral infections, the indications given by the specialists and always be alert, but never anxious; Because stress and nerves have never brought solutions.
