 [ Symptoms ] contagious period for cold i have been sick with a cold off and on for about 2 months the last time i got sick was about week ago i am going to visit my sister and her newborn is it safe to do so [ Disease ] a cold only lasts a week so i am concerned that you have been sick for two months you are either getting back to back colds or there is another reason for your symptoms since i have no way of knowing exactly what you have or when you contracted your cold i really cannot tell you if you are contagious or not
