Bacterial from Viral
Although the prospects of returning to a world without antibiotics may be grim, there is still time to do something about it.
Bacteria by Using Antibiotics Less
Parents can take heart from the results of several recent studies. One study examined children who harbored strains of Streptococcus pneumoniae that resisted antibiotics. They found that, without receiving another antibiotic for six months, the number of strains of bacteria that resisted antibiotics decreased dramatically from 50 percent to about 5 percent. So if parents and doctors use antibiotics only when children really need them, the number of children that harbor resistant Streptococcus pneumoniae will decrease.
Other studies were performed in Iceland, Finland, and Japan, where, similar to the United States, the number of children that harbored resistant Streptococcus pneumoniae was alarmingly high. In response to this problem, each of these countries launched national campaigns to decrease antibiotic use.
