When dealing with respiratory infections, illnesses that affect the air‑way and lung tissue. Also known as lung infections, they range from a simple sore throat to severe pneumonia that can require hospitalization.
Most viruses, tiny particles that hijack cells to multiply trigger colds, flu, and COVID‑19, while bacteria, single‑cell organisms that can invade lung tissue are behind strep throat, bronchitis, and bacterial pneumonia. Recognizing whether a virus or a bacterium is at work is crucial because antibiotics, drugs that kill or stop bacterial growth only help with bacterial cases and can be harmful if misused on viral infections. Prevention relies heavily on vaccines, biologic preparations that train the immune system—flu shots, COVID‑19 boosters, and pneumonia vaccines cut the risk of severe disease dramatically. Good hygiene, adequate rest, and avoiding smoke further lower the chance of catching or spreading an infection.
Understanding the link between symptoms, the responsible pathogen, and the right therapy lets you act quickly and avoid complications. Below you’ll find a curated collection of articles that break down specific infections, compare treatment options, and offer practical steps you can take right now to protect your lungs and breathe easier.
