Occupational asthma is characterized by variable airflow limitation or hyper-responsiveness or inflammation due to causes and conditions attributable to a particular occupational environment and not to stimuli encountered outside the workplace. During the period 1995-1997 in Israel, 164, 197 and 191 persons died of asthma each year, respectively. The crude annual asthma mortality rates in Israel per 100,000 population in 1996 were 2.32 among men and 4.58 among women
However, there are some indications that asthma mortality has begun to decrease in certain subpopulations in Israel. Mortality among Israeli asthmatic women decreased in 1997 compared to 1996 and 1995 (while mortality among men continues to rise) the overall hospitalization rate in 1990 was 150 per 100,000. There is no particular treatment for occupational asthma. Prevention is better for occupational asthma, if occupational asthma is not correctly diagnosed early, and aren't protected or removed from the exposure, it can cause permanent changes to your lungs. Avoid or reduce exposure to irritants that can trigger symptoms in most asthmatics such as smoke or cold air. Researches are going in International Study of Asthma and Allergies in Childhood (ISAAC) about Asthma.
