If you are talking about virus as in illnesses, then it is because they are immune to antibiotics and mutate.
If you are talking about Computer Viruses they are hard to totally eliminate as they constantly mutate
We cure viruses by reformatting the computer's CPU.
you don't...
It's cure is three live viruses mixed together.
Absolutely NO. Antibiotics are strictly for bacterial infections. Antivirals are used for viruses but do not cure them rather they just inhibit their reproductive abilities.
One major problem that makes a viral infection so hard to cure is that they mutate so rapidly. It also hard to find drugs that will work. Tamiflu is an antiviral that acts against an enzyme that the virus needs to break out of the host cell and spread but many viruses are so simple that there are very few ways to stop them.
Viruses are nonliving and that fact makes it hard for us to come up with antivirals.
bacteria and they don't cure viruses
viruses
The ability of viruses to hide in the host's DNA. The fact that viruses can hide very well inside your dna.
prevenion is better than cure
No. HIV is a virus, we currently do not have the ablility to cure ANY viruses, not just HIV.
Viruses are difficult to cure because they invade host cells to replicate, making it challenging to target them without harming the host cells. Additionally, viruses can mutate quickly, leading to the development of resistance against treatments. This complexity makes it challenging to develop a universal cure for all viruses.
