Viral infections including flu or common cold show symptoms similar to bacterial infections. But antibiotics do not help in treating viral infections. Severe viral infections are treated with antiviral drugs.
While most viruses are pathogenic and harmful, just like bacteria, not all viruses are bad. Some viruses, called bacteriophages, can kill harmful bacteria.
Infections caused by viruses at a young age are also very important for babies to ensure the proper development of immune systems.
Thanks to advances in scientific research and advances in technology, we are able to understand more about the complexities of the vast microbial world that is invisible to our eyes yet form an integral part of our lives.
