Why making of antiviral medicines are difficult?
Designing safe and effective antiviral drugs is difficult because viruses use the host’s cells to replicate.
This makes it difficult to find targets for the drug that would interfere with the virus without also harming the host organism’s cells..
Which of the following is a viral infection?
Viral Infections Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, Ebola, and COVID-19. Viruses are like hijackers.

How do antiviral drugs fight viral diseases?
Antivirals interfere with an important enzyme of the influenza virus, called neuraminidase. The drugs keep the virus from escaping from one cell to infect a neighboring cell. They are most effective if started within a day or two of the onset of symptoms.
How does an antiviral drug work?
Antiviral drugs work by stopping the infection process. Depending on the virus and medicine, the blocking of the process can occur at many different locations. One drug prevents the virus from fusing to the healthy cell by blocking a receptor that helps bind the virus to the cell.

What is the limitation in making antiviral drugs which does not apply to antibacterial drugs?
As viruses lack cellular structure and metabolic activities, antiviral driugs are difficult to prepare. Moreover viruses use its host’s metabolism; therfore can’t be targeted easily. So, even if you give some drugs, it may not be effective next time.
What do antibiotics mean?
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic.

Why is it difficult to make antivirals Class 9?
It is difficult to make antiviral medicines than making antibiotics because viruses have few biochemical mechanisms of their own. They enter the host cells and use their machinery for their life processes. So, antiviral medicines will work against the host body.
