Why are Viruses Hard to Kill and Tough to Treat? like COVID-19

Virus are among the biggest threats to humanity, with the current pandemic showing how these virus can shut down countries, halt entire industries and cause untold human suffering as they spread through communities. Here i am going to tell you Why are Viruses Hard to Kill and Tough to Treat? like COVID-19. Let's see

1. Hard to Kill & Cure

Viruses have also evolved in such a way that they are difficult to kill. They are very hard to cure as we see Corona virus. Viruses don't really do anything, they are effectively inert until they come into contact with host cell. "But as soon as that happens, they switch on and come to life".

2. Odd Thing

The very odd thing of these infection agents is part of what makes them very difficult to defeat. They are harder to target with drugs. The viruses are not alive, the fact is that "they are not alive means they don't have to play by the same rules that living things play".

3. Bacteria Vs Virus

As we know , Antibiotics, which are used to fight bacteria's infection, attack bacteria's cell walls, block proteins production and stop bacteria from reproducing. But they are not effective against viral infections, because viruses don't carry out any of those processes on their own. Rather, viruses need to invade and take over host cells to replicate. But a virus cannot break into just any cell in the body. Instead one of its proteins will bind to another protein-which then allows the virus to hijack certain cells. With this outbreak, the coronavirus so-called spike protein primarily fits "locks" that are present on lung cell, which is why COVID-19, the diseases it causes is mainly a respiratory illness.

4. In Simple Words

It is basically act like a thief inside the cell, stealing all the cellular machinery and re purposing those machines to make more of the virus. Viruses are sneaky and they are often able to fly under radar and cause a lot of damage before any alarm are triggered. By the time an immune response kicks in, it's often too late.

5. Anti Viral Drugs 

Anti Viral drugs are also challenging to develop because they need to work very specifically to combat certain viruses. That's different from antibiotics, which can treat a variety of bacterial infections. And because viruses have different "keys" to break into cells, there are fewer common targets for drugs to block infections.

Even when antiviral drugs are available for some viruses, they don't necessarily cure the infection. Drugs used to treat HIV, for instant are effective at suppressing virus replication but don't eradicate it. Seasonal influenza can be treated with an antiviral medication, which can help shorten the duration of the illness but it's common to be able to detect the virus after a patient recovers.

 6. Completely Cured Virus as of Now

The only Virus that can truly be cured by drugs is Hepatitis C only. It means it is very Hard to kill and tough to teat a viral infection. Many countries are on the way to invent a drug for COVID-19, but as of now no drug or vaccine are there.

Conclusion

"Viruses just want to make more of themselves and find new hosts to infect", "its truly like survival of the fittest". Many health agency put their best effort to control this virus, but to date no result. Now it is suggested that we all to live with corona till the vaccines are made. we have to change our habits and follow social distancing each and every time, that is the only way to move ahead

As of Now Corona doing same with our Earth
