Antibiotics do nothing to treat a viral infection. However, in some cases a physician thinks a patient needs a bacterial infection treated in order to throw off a viral infection.
Antibiotics only cure bacterial infections. Antibiotics will not cure a viral infection.
So it can be properly treated; for example, if you think someone has a bacterial infection, you would treat that person with antibiotics. If that person actually has a viral infection, they should be receiving anti-virals, not antibiotics. Antibiotics have not affect on viruses.
Anti biotics will not cure a virus .
No. Antibiotics are given to them only when they are ill with a bacterial or viral infection. Cows have antibodies and immunoglobins, but not antibiotics.
No, antibiotics are made for bacteria. A virus is something else all together. However, it is not uncommon for someone to be sick with a viral infection, such as the flu, and then get sick with a bacterial infection immediately after due to their immune system being stressed. In those cases, antibiotics may be given.
Antibiotics are given, even though the infection is viral, to prevent infection while the body heals.
Antibiotics only work against BACTERIAL infections. A VIRAL infection is not a BACTERIAL infection. A bacteria is a small complex living cell - antibiotics kill bacteria A virus is a simple strand of DNA in a protein coat - antibiotics have no effect on viruses.
Sometimes doctors will prescribe them to either prevent or treat a secondary infection. Some examples are lung or ear infections that may develop as a result of an initial viral infection.
