Bacterial or Viral? Your Guess Is Dangerous

 When you get sick, it’s likely you don’t consider what actually made you sick. A pesky virus, some yucky bacteria, pollution, stress, or not getting your full 8 hours can blend together into one diagnosis: sick. And while pin-pointing the exact cause of a mild cold is not necessary for everyone, completely ignoring the root cause is not healthy either. In fact, there is one critical distinction everyone must learn to recognize: viral versus bacterial.

​

A virus is a non-living microscopic fragment that cannot survive without a living host. Because it is not technically alive, it invades our cells to survive and forces them to reproduce the virus (think COVID or influenza). Bacteria, on the other hand, are living organisms that can survive outside a host, and while mostly harmless or even helpful, some can cause serious damage known as infections through open wounds, the mouth, and nose (think food poisoning or strep throat).

​

Both viruses and bacteria are around us in staggering quantities all the time, harmless. When we need to pay attention is when you or someone you know becomes sick. Knowing the indicators of a viral sickness versus bacterial infection could not only massively help the individual, but your entire community. The reason for this is what has come to be known as antibiotic resistance. In 1928, Penicillin, essentially the first antibiotic was discovered. Since then, antibiotics have transformed the medical world and saved millions of lives, as before their invention, a minor injury could be fatal if introduced to the right bacteria.

​

However, antibiotics have been treated as a one stop cure, which they are not. They do not work on anything besides bacteria, especially not viruses. Yet, many providers and patients recommend or request antibiotics for viral illnesses, like the flu. When this happens, not only is good bacteria killed in the body for no reason, the genetically resistant bacteria are able to survive, reproduce, and quickly become the entire population of bacteria, creating what is known as superbugs. These antibiotic resistant bacteria can wreak havoc by sharing this code with harmful bacteria, who are then unaffected by the current antibiotics, and require much larger, more potent doses to eliminate

 

For many, they don’t realize they are building resistance, so they continue taking unnecessary antibiotics and the cycle continues. Antibiotic resistance renders once-curable bacterial infections difficult or impossible to treat. This leads to severe, prolonged illnesses, higher mortality rates, and increased medical costs due to the need for expensive second-line drugs and extended hospitalizations.

​

We have the chance to reverse this trend, however, through education, informed decisions, and thoughtful conversations with healthcare providers. For starters, here are a few major differences between viral and bacterial illnesses. Viruses often have more widespread symptoms such as a runny nose, coughing, and fever, whereas bacterial symptoms can be more localized like redness or swelling in a specific area. It’s pretty hard to tell them apart on symptoms alone, so you should always consult with a provider before making any decisions. Some more preventative measures are: never demand antibiotics, take antibiotics exactly as described and never “save them for later”, and keep good hygiene (hand washing and safe food practices).

​

If we pay attention and stay educated, we can keep harnessing the power of antibiotics for the positive, but if we don’t, we risk losing one of modern medicine’s greatest achievements entirely.
