💡TL;DR: Yes, pneumonia can be contagious when it is caused by a virus or bacteria, and it spreads at close range in cough and sneeze droplets. Viral cases are contagious for several days. Bacterial cases usually stop spreading about 24–48 hours after effective antibiotics. Walking pneumonia (Mycoplasma) can

💡TL;DR: A peak flow meter is a small home tool that shows how open your airways are by measuring how fast you can blow out (L/min). Check it daily and compare the highest of 3 blows to your personal best to guide your asthma action plan. Green 80–

💡TL;DR: Bronchitis irritates the airways and is usually viral; pneumonia infects the lung's air sacs and tends to be more severe. Expect bronchitis to improve in 1–3 weeks and pneumonia to take 1–2+ weeks, with fatigue lingering. Antibiotics usually don't help acute bronchitis,

💡TL;DR: A NIOSH‑approved N95 respirator that seals well is the best protection for wildfire smoke. Expect to pay about $1–$3 per disposable N95, while reusable P100 respirators cost roughly $30–$150 and replacement filters $8–$20 per pair. Cloth or simple surgical masks won’t protect you

💡TL;DR: If you are wheezing, first decide if it is an emergency, then use the fastest safe steps to open your airways. Mild wheezing with easy breathing can often be calmed at home with rescue inhalers, nebulizers, or breathing exercises, while severe shortness of breath, blue lips, or noisy

💡TL;DR: Most sore throats are viral and get better in a few days; only about 5–15% of adults and 20–30% of children have strep (CDC). Strep usually starts suddenly with severe throat pain and fever and no cough, while viral sore throats build more slowly with cough

💡TL;DR: Croup = a barky upper‑airway cough that peaks over 1–2 nights, RSV = a wet cough with wheeze that runs about 1–2 weeks, and whooping cough = long coughing fits with a whoop that can last for weeks. Nearly all children encounter RSV by age 2 (CDC), while

💡TL;DR: After COVID-19, a new or returning low fever, a cough that worsens instead of easing, and new shortness of breath within 1–3 weeks can signal walking pneumonia. See your doctor to confirm with a chest X-ray; don’t assume it’s just long COVID. Most people feel

💡TL;DR: Recurrent croup means more than two barky-cough episodes in a year or croup showing up outside the usual age window (about 6 months to 3 years). It can be a risk signal for asthma, but most children do not develop chronic asthma. Practical next steps: watch for wheeze
