Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus. However, antiviral medications and vaccines are specific for viruses.

Why do some antibiotics not work on bacteria?
That's called antibiotic resistance. Some bacteria can naturally resist certain kinds of antibiotics. Others can become resistant if their genes change or they get drug-resistant genes from other bacteria. The longer and more often antibiotics are used, the less effective they are against those bacteria.
What happens if antibiotics don't work for bacterial infections?
In some cases, the antibiotic-resistant illness can lead to serious disability or even death. Resistance can happen if the bacterial infection is only partially treated. To prevent this, it is important to finish taking the entire prescription of antibiotics as instructed, even if your child is feeling better.
What is it called when antibiotics are unable to kill bacteria?
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.
Can your body fight bacterial infections without antibiotics?
Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics. We rely on antibiotics to treat serious, life-threatening conditions such as pneumonia and sepsis, the body's extreme response to an infection.
How long does it take for antibiotics to work for bacterial infection?
Antibiotics start working almost immediately. For example, amoxicillin takes about one hour to reach peak levels in the body. However, a person may not feel symptom relief until later. "Antibiotics will typically show improvement in patients with bacterial infections within one to three days," says Kaveh.
What happens if antibiotic course is not completed?
You should always finish a course of antibiotics, even if you start to feel better. If you do not finish the course or miss several doses, the infection may return. Never keep antibiotics you've taken in the past with a view to using them again if you're unwell in the future.
Why didn't the antibiotics work for Addie?
Addie's doctors had run out of the most common antibiotics used to treat these serious bacteria so, in desperation, they turned to an antibiotic known as colistin. Colistin is very powerful, but it is also so highly toxic to the kidneys and other organs that doctors rarely use it.
What is the major contributor to the increase in antibiotic resistance in bacteria?
Antibiotic resistance is accelerated by the misuse and overuse of antibiotics, as well as poor infection prevention and control. Steps can be taken at all levels of society to reduce the impact and limit the spread of resistance.
In which of the following circumstances can bacterial resistance to antibiotics occur?
Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm. Bacteria can do this through several mechanisms.
Can bacterial infections be treated with antibiotics?
Antibiotics are used to treat or prevent some types of bacterial infection. They work by killing bacteria or preventing them from reproducing and spreading. Antibiotics aren't effective against viral infections, such as the common cold, flu, most coughs and sore throats.
How can you prevent infections with resistant bacteria?
There are many ways that drug-resistant infections can be prevented: immunization, safe food preparation, handwashing, and using antibiotics as directed and only when necessary. In addition, preventing infections also prevents the spread of resistant bacteria.
