Wow that sounds like a scary disease! I have been coughing for a month or so and it won't stop so it looks like i must have a mild case of hyperhemoptsis! The coughing up blood and mucus would be scary and having all those symptoms. The RNA genome also allows it be very scary and unpredictable especially with it being an airborne disease that can spread so easily. Towards the end does not sound fun especially coughing so much and not being able to breath. Yay that sounds like such a simple solution to be able to keep these patients alive and healthy again!
