Understanding pneumonia: causes, signs, and prevention
As winter approaches, concerns about catching colds, coughs, flu, and pneumonia tend to rise. While these illnesses can occur any time, their prevalence in colder months increases. Knowledge is key to prevention, so here’s essential information about pneumonia, including its types, causes, symptoms, and protective measures.
What is pneumonia?
Pneumonia is an infection that causes inflammation in the air sacs of one or both lungs. It can range from mild discomfort to severe, life-threatening illness, especially dangerous for infants and young children.
Pneumonia is typically caused by germs such as bacteria and viruses present in the environment. Normally, a strong immune system wards off these pathogens, but when immunity is compromised, infections develop.
- Community-Acquired Pneumonia (CAP): Contracted outside healthcare settings, often after viral infections like the flu. It’s the most common form, especially prevalent in winter, often requiring hospitalization.
- Hospital-Acquired Pneumonia (HAP): Develops in hospitalized or healthcare-visited patients, often more severe and caused by resistant germs.
- Healthcare-Associated Pneumonia: Contracted in outpatient clinics, dialysis centers, or nursing homes.
Symptoms vary from mild to severe, influenced by age, health status, and infection type. Common signs include:
- Chest pain during breathing or coughing
- Mental confusion in seniors over 65
- Cough with or without phlegm
- Fatigue and weakness
- Fever, chills, sweating
- Low body temperature
- Nausea, vomiting, diarrhea
- Difficulty breathing
Mild cases mimic flu or cold symptoms but last longer. Infants may show irritability, vomiting, difficulty feeding, or respiratory distress.
Pneumonia itself isn’t contagious, but the germs causing it are. These pathogens spread via coughs or sneezes, inhaled by others, leading to infections.
Prevention is critical. Vaccination against pneumonia, good hygiene practices, avoiding smoking, and maintaining a healthy lifestyle strengthen your defenses. Adequate sleep, balanced diet, and regular exercise support immunity.
