Why do you suppose that viral illnesses are more difficult to treat than bacterial illnesses?
Many human illnesses are caused by infection with either bacteria or viruses. Most bacterial diseases can be treated with antibiotics, although antibiotic-resistant strains are starting to emerge. Viruses pose a challenge to the body’s immune system because they hide inside cells.
How do you think the treatment for viral and bacterial illnesses differ?
As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren’t effective against viruses.

Can your body fight bacterial infections without antibiotics?
Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.
Why a virus is considered non living?
Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
How long do viral infections last?

What drugs kill viruses?
Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit its development.
Why is it difficult to develop drugs to treat viral infections?
Viral diseases cannot be cured by antibiotics, as they reproduce inside the host cells. It is very difficult to develop antiviral drugs, as they might damage the host cell whist killing the virus .
How do you tell if it’s viral or bacterial?
Your doctor often can diagnose you through a medical history and physical exam. The doctor may order blood or urine tests or a spinal culture to help pinpoint a viral or bacterial infection.
How does your body fight off viruses?
Via interferons. Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses. Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.
Can a viral infection become bacterial?
Darville highlighted the possibility of bacterial infection in viral otitis media, and McCullers said human metapneumovirus, rhinovirus, respiratory syncytial virus and parainfluenza all can lead to secondary bacterial infections.
