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.
The incubation period which is the time span between the infection and the visibility and severity of the symptoms for the whooping cough is about 7 to 10 days, but in worst cases it may go on for as long as 21 to 25 days. The answer to the question of how long does the whooping cough last is also dependent on the prevention that is taken. Proper vaccination and medication with avoiding the use of any cold food (edibles or beverages) can prevent the severity and will help in reducing the days of healing.
