Antibiotics do not work against viral infections becausea)viruses live...
Explanation:
Antibiotics are drugs that are used to treat bacterial infections. They work by targeting specific biochemical pathways that are unique to bacteria. These pathways are essential for the survival of bacteria, but are not present in human cells. Therefore, antibiotics can selectively kill bacteria without harming human cells.
Why antibiotics don't work against viral infections:
Viruses are very different from bacteria. They are much smaller and simpler in structure, and they do not have the same biochemical pathways as bacteria. This means that antibiotics, which are designed to target bacterial pathways, are ineffective against viruses.
How viruses work:
Viruses are essentially packets of genetic material (DNA or RNA) surrounded by a protein coat. They cannot reproduce on their own. Instead, they must invade a host cell and hijack its machinery in order to replicate themselves. Once inside a host cell, a virus will use the cell's own machinery to produce more viral particles, which can then infect other cells.
Why antibiotics are not effective against viruses:
Antibiotics are designed to target specific biochemical pathways that are unique to bacteria. These pathways are not present in viruses. Therefore, antibiotics have no way to target the virus itself. They may be able to kill any bacteria that are present in the body, but they will not have any effect on the virus.
The dangers of overusing antibiotics:
Overusing antibiotics can lead to the development of antibiotic-resistant bacteria. When antibiotics are used excessively, bacteria can evolve to become resistant to them. This means that the antibiotics will no longer be effective against these bacteria. This is a major public health concern, as antibiotic-resistant bacteria can be very difficult to treat, and can lead to serious infections that are resistant to all known antibiotics. Therefore, it is important to use antibiotics only when they are needed, and to follow the instructions of the doctor or pharmacist carefully.
