Antiviral Medicine
The War Against Viruses
-
However, virus may be not completely eradicated and some may be dormant in cells.
Viral infections still claim lives of millions of people each year and is responsible for even greater number of illness.
Thus the development of effective treatments against these viruses is considered the most important issue in modern medicine.
Viruses that live within a host cell is difficult to target and antibiotics are no use for them, this is because antibiotics target the cell wall which viruses dont have.
It is also a problem because viruses, once they inhibit a host cell, can multiply very quickly and mutate fast, bringing along the problem of new virus strains into the equation.
Prophylactic treatment - is a prevention against viral disease
Vaccines stimulate the body to prepare antibodies along with memory cells which give immunity to the person.
New vaccines are needed to be researched and produced as mutation of viruses has lead to new strains being discovered.
The main strategy is using antivirals- which stops new viral particles to be created. Some work by targeting the DNA, some block enzyme activity of host cell.
AIDS: A Viral Pandemic
AIDS - anti immune deficiency syndrome is caused HIV, the human immunodeficiency virus
Transmitted through sexual or parentarel exposure to fluids like blood, semen, mucus that contains HIV.
Characterized by the failure of the immune system causing the person to be threaten with other diseases
HIV primarily effects the white blood cell which are called CD4+ T cells. They bind to the specific receptor on the cell surface and penetrate the cell

The RNA is released into the host cell and then enzyme transcriptase controls the synthesis of the viral DNA from the RNA. The DNA then integrates with the cell's DNA and replicates with it when the cell divides.
