O98: Maternal infectious and parasitic diseases classifiable elsewhere but complicating pregnancy, childbirth and the puerperium

O98.3: Other infections with a predominantly sexual mode of transmission complicating pregnancy, childbirth and the puerperium

There are diseases that are particularly transmitted during sex. These diseases are also called sexually transmitted diseases. They are usually caused by specific pathogens. The pathogens can for instance be transmitted via vaginal fluid or semen. The pathogens may also be transmitted from a sick mother to her new-born child when she gives birth.

Your illness is making the pregnancy, the birth or the weeks after the birth more difficult. You may also already have had this kind of disease before your pregnancy. Your illness may then also have got worse due to the pregnancy, the birth or the weeks after the birth.
