Antibiotics
They don't. Antibiotics are targetted at bacteria. There are also antifungals and a very few, quite new, not 100% effective anti-virals.

Drug resistance in bacteria can be harmful to humans because it can result in less effective treatments for infections. Higher doses may be needed to treat infections, and so treatment may have more risks. In some cases, antibiotics may no longer be effective at all.
Yes, they can cure bacterial infections but they cannot cure viruses. :)
No Penicillin is not effective on viral infections.

Viral Infections canno't ever be treated bacause viruses are not alive. They come in contact with a cell and inject their DNA into the cell. They canno't be treated, but however can be controlled with pills and creams.
There are treatments for HIV but no cures. There are a number of antiretroviral medications that prohibit viral replication and can delay the effects of HIV or its associated infections and conditions (like AIDS).
There are no antibiotics that are effective against viruses. In fact, they should never be used unless a secondary bacterial infection is present and this is best determined by culturing the drainage, whether it is from the nose, throat, blood, or sputum. Because some Dr.'s have overprescribed antibiotics, many of the common bacteria have developed resistance.
For the most part, no. Antibiotics work for bacterial diseases but are not effective against viruses. Viral infections require time and rest to overcome. Exceptions: Antiretroviral medications hinder the multiplication of the HIV virus, and there are certain medications that will lessen the severity of influenza in individuals who are especially vulnerable.
No, antibiotics are only effective against BACTERIAL infections and a cold is a VIRAL infection.
Antibiotics can cure almost all bacterial infections. There are a few drugs that can treat viral infections. Many viral infections can be prevented by vaccinations. Many viral infections do not have a cure.
Viral infections have not been cured. Bacterial infections usually can be.
Both bacterial infections and viral infections can be contagious or not contagious. Some viral infections are not spread from human to human or are only rarely spread that way. TB is a contagious bacterial infection.
Other viral infections may also strike the patient, including croup, bronchitis, laryngitis, or viral pneumonia.
