About an antibiotic　抗生物質について

You may have been taking antibiotics and other drugs to treat your cold. However, you are thencomplicated by bronchitis or pneumonia. Why does it happen?

The considerable reasons may be, the bacteria or virus is very strong; the drugs you are taking are not effective enough; or your resistance to the illness is very weak. In infectious diseases caused by bacteria or viruses, these three factors interact with each other to affect the disease status. In a viral infection, because there is less effective medication, it is very important to keep your strength up. In a bacterial infection, keeping strength up is important as well, even so it is more important to use antibiotic correctly.

However, it is not easy to choose [effective antibiotic]. Before making decisions, doctors must analyze what is the disease-causing bacterium and which antibiotic is the best to fight it effectively. In fact, there is not one antibiotic that is predictably effective against all types of bacteria. Especially, antibiotic resistant bacteria, disease-causing bacteria have become resistant to antibiotics, is an increasing common problem for public health now.
