The classic disease prevention system for asthma is based on prima ry, secondary, and tertiary prevention. Primary prevention is based on risk reduction. So, it works by eliminating occupational and behavioural factors which promote development of asthmatic symptoms. Secondary prevention seeks to restrict disease progression by using screening tools. This makes it easier and more cost-effective to control asthma than when symptoms start appearing. Tertiary prevention seeks to lessen the disastrous effects produced by asthma on body. It can also include modification of behavioural and environmental factors to bring quality in life. Much research is done to scrutinize the impact of asthma on society. The cost of asthma to society is staggeringly huge. The relationship between asthma prevalence and society is well established.
