It sounds also alittle like what my son has. It is called RSV ask your doctor about it. It does cause long term asthma and u may be put on a nebulizer like my son. The best thing to do it give him the meds as soon as he starts to show symtoms like coughing or sneezing. That is what usually is the beginning of my son't outbreaks. Your local hospital also should be able to direct you to a local asthma support group. Best of luck.
