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.
In these cases, your cough may last for 3 to 8 weeks. With Bordetella pertussis, the bacterium that causes whooping cough, your cough can linger for months, even though the bacteria that triggered your symptoms have been eliminated.
