Viruses are known as small biological units, a lot tinier than bacteria. Whilst a bacterium may be created from a few thousand proteins, most viruses amount to as few as 10 to 100 proteins.
And, not like bacteria, viruses cannot replicate themselves on their own. This is why they are not believed in as living items. Viruses can only replicate themselves by colonizing the cells of a host, like us, and that is what makes them hazardous.
Once inside the body, except if a virus can be swiftly destroyed by our immune system, it will try to break into cells and hijack our proteins to reproduce their genome (the total of an organism’s DNA). This is why it is difficult to create cures to kill viruses – antivirals.
Scientists can mark microbial infections utilizing antibiotics that infect the proteins in bacteria. But because viruses use our proteins, antiviral therapies infecting these proteins can create harmful side effects. This means that efficient antivirals must be explicitly targeted so they only strike those proteins we know are crucial for the virus. That way scientists can minimize any possible damage to the general health of the patient.
