Prevalence of Asthma in WA 3Prevalence of Asthma in WA, Australia, and WorldIntroductionPatterns and types of asthma may be changing but admission in hospital rate is increasing in few of the western countries. Most of the prevalence studies indicate that it is maximum in children although their studies are based on some cumulative data collective from some western countries. There is an estimate that worldwide 300 million people suffer from asthma, with around 2, 50,000 deaths annually, all these deaths are premature and can be easily avoided. As per few types of research, it is estimated that asthma patients will increase by 100 million by 2025. Few workplace conditions like gases, fumes and dust exposure are generally responsible for 11% cases of asthma out of which 70% have allergies due to some or the other reason. It is anessential that asthma becomes the global priority because it is the biggest burden of disease and should be taken on top most priority by the governments (Shin and Lee 2017). We must also focus on various factors which are stopping us from giving proper care to low income groups andthis can be done by strengthening our technologies efficiently. In Australia and Westerns Australia, it is most common in children, few types of research show that there is no change in the data of asthma among adults, but there are reports showing an increase in numbers of cases of asthma among children. Government is equally working on to decrease this data by organizingmany awareness camps such as National Asthma Campaign. In 1981 a research was conducted in Busseltone, Western Australia both the protocols objective and subjective were included in thestudy, a total of 6000 people were asked to attend the survey out of which 3590 turned up (Shin and Lee 2017). Later in 1990 again the same research was conducted to know whether the data

Some studies show that it can be either genetic or non-genetic factor which can cause asthma. There are two things to be distinguished triggers and causes of asthma.
Prevalence of Asthma in WA 5Asthma is also associated with many other factors like smoking and air pollution as it is an airway inflammatory disease which involves both impaired airflow and airway inflammation. Most important triggers of asthma are second hand smoke and ciggerete smoking (Shankardass et al. 2015). Around 25% of 35% asthmatic people are smokers. Prolonged exposure to these triggers in asthmatic patients tends to decrease the lung functionality leading to severe health conditions. The purpose of this study is making such people aware of the negative effects of smoking and SHS on their health so that it can be controlled in the early age (Shankardass et al. 2015). Below table shows the mechanism of damage from smoking and airway.Table 1. Examples of Mechanisms of Smoking andAirway Damage in AsthmaMechanisms References
