A new study in the USA has revealed that the reason of increase in the Asthma in children in some areas of Newyork can be cockroaches. During the study it was observed that in some areas of Newyork the rate of asthma in children was 19 %, it means that one child out of every 5 children is suffering from asthma. while in other areas the disease rate is 3 or less than 3 %.. In the past heavy traffic, smoke from factoriesand other external sources of pollution were considered the causes of the disease. However, now the researchers from Columbia University say that the areas where the rate of asthma in children is high, the proportion of anti-bodies in their blood against the proteins of cockroaches may be doubled. It means that cockroaches are more in their homes ans children are possibly suffering from allergy to cockroaches.. In addition , where there high rate of asthma disease prevails, then cockroach created allergen will be higher too in their homes in the dust of households. The author of the study Mathew Parzano Viski says that observations of the study reveals that cockroaches can be the reasons of asthma . He added that allergen created by cockroaches is the definite reason of higher rate of asthma in Newyork city and its surrounding areas. .
