isn't it a bit much having 3 colds in 4 months? . had the first cold nov8 five days after a flu shot; dec9 was the 2nd head cold; jan gave me a break; feb10 i came down w/ a sore throat followed by cough body aches and chills adding a head cold on feb13; previously i had gotten one cold earlier last year and none before my arrival in puerto rico on jan'09; i'm a female 58 yo
there are over 200 different cold viruses. the more people contact that you have the more likely you will get one of them. especially in the fall and winter months. i do not think that three cold in four months is that unusual.
