A grandmother and two teenagers survived an apparent murder-suicide that left a husband and wife dead inside a home in Aldie, Va., the Loundoun County Sheriff's Office said.
6 doctors agreed: Croup: Croup is usually self-limiting, lasting 5-7 days, but as with any other respiratory infections, cough is usually the last symptom to go away. Postinfectious cough can last up to several weeks, and it can trigger brochospasm especially if the child has asthma.
Adult croup patients usually sense the starting of a respiratory infection of the upper airways during the croup incubation period of two to four days. In this period, a low-grade fever, rhinorrhea and a mild cough are the only symptoms that appear. Later on, inflammation, erythema and exudate are caused because of release of inflammatory factors resulting in cough. The cough of croup resembles the sound made by seals and makes a harsh barking noise.
