One illness that I’ve heard since childhood is pneumonia. I’m unsure if it’s just a Southern thing or an older generation’s caution, but it seemed like an endless list of things that could cause pneumonia. The main one I can recall was going outside with wet or damp hair, especially if it showed any slight chill in the air. Another popular one amongst my grandparents was going outside without putting something on your arms. Nothing like a good Southern myth! More accurately, according to the CDC (2021), causes of pneumonia are viruses, bacteria, and fungi. In the United States, common causes of viral pneumonia are influenza viruses, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19). Common causes of bacterial pneumonia are streptococcus pneumoniae (pneumococcus) and, especially in kids, mycoplasma pneumoniae (CDC, 2021). Depending on where you contract the illness, there are also several different types of pneumonia; this can also help determine which bacteria, fungi, or virus caused the illness. The bacteria and viruses that most commonly cause pneumonia in the community are different from those in healthcare settings. However, clinicians are not always able to find out which germ caused someone to get sick with pneumonia (CDC). According to the CDC, here are the definitions and distinct differences in the different forms of pneumonia:
- Community-acquired pneumonia is when someone develops pneumonia in the community (not in a hospital).
- Healthcare-associated pneumonia is when someone develops pneumonia during or following a stay in a healthcare setting. Healthcare settings include hospitals, long-term care facilities, and dialysis centers.
- Ventilator-associated pneumonia is when someone gets pneumonia after being on a ventilator, a machine that supports breathing.
Either form of pneumonia contracted can cause serious health issues and often be fatal. So, it’s best to take all precautions, both factual and mythical. I still don’t go outside with wet hair to this very day, and I’ve never had pneumonia. I guess Southern remedies have some truth to them.
