Long-Term Outcome of Individuals with Borderline Thrombocytopenia

Childhood asthma is a serious global public health problem. According to the World Health Organization [1], asthma is the most common chronic disease in children. In some areas of the world the incidence in children is over 50% [1]. Although no single specific cause of asthma has been found, a number of predisposing factors have been identified and are the targets of ongoing clinical investigations. Lower respiratory tract infection (LRTI) caused by respiratory syncytial virus (RSV) in infancy has been identified as one such potential risk factor.
