💡TL;DR: Most upper respiratory infections (URIs) are contagious because they are caused by viruses that spread easily through droplets and on your hands. You are usually most contagious in the first 2–3 days of symptoms and can spread infection for about 3–10 days overall. Stay home while

💡TL;DR: ALS gradually weakens the breathing muscles, so most people start with noninvasive ventilation (a BiPAP mask) when symptoms appear. A tracheostomy with a ventilator can extend life by a median of about 21 months after surgery, but it usually means 24/7 dependence on the machine and caregivers

💡TL;DR: Most babies, children, and adults with RSV get better with supportive care alone and never need an antiviral drug. Ribavirin is an older antiviral that is reserved for rare, very high-risk cases, such as some hospitalized infants and severely immunocompromised adults. Because it is expensive, difficult to administer,

💡TL;DR: Most people with RSV are contagious for about 3 to 8 days after symptoms start, and you can begin spreading the virus 1 to 2 days before you feel sick. Babies, toddlers, older adults, and people with weak immune systems can shed RSV much longer, sometimes for 3

Is There a Test for RSV? 💡TL;DR: Doctors can test for RSV with a quick nose swab that looks for the virus in your mucus. Testing is usually reserved for infants, older adults, and people with high-risk conditions or severe breathing problems, not for every mild cold. Rapid tests

💡TL;DR: Incentive spirometers are devices you slowly inhale through to exercise and reopen your lungs, while peak flow meters are devices you blow into to measure how fast air leaves your lungs. Use a peak flow meter mainly for day-to-day asthma or lung function monitoring, and an incentive spirometer

💡TL;DR: Chest percussion therapy machines use vibrations or gentle thumps on your chest to loosen thick mucus so you can cough it out more easily. They are usually prescribed for chronic lung or neuromuscular conditions when coughing alone is not enough. Vest systems and handheld percussors can cost from

💡TL;DR: Nebulized furosemide means inhaling the diuretic Lasix as a mist to see if it can ease shortness of breath, but it is an experimental, off-label treatment rather than a standard therapy. Generic furosemide tablets are inexpensive, often costing under $10 per month for many patients, while there is

💡TL;DR: COVID-19 can trigger new or worse asthma in a small minority of people, but most people recover without long-term breathing problems. Studies suggest adults who have had COVID-19 are roughly twice as likely to be diagnosed with asthma in the following months as those who were never infected,
