Doesn't "cause" it: But some viruses that cause lung infection may start as what appears to be a cold. Moreover, colds often turn into bronchitis which is mistaken for a lung infection. Finally, some people have poor immune defenses (smokers for instance) and get both colds and pneumonia more commonly.
