The Dutch Institute for Health Care Improvement revised guideline, 'Sexually transmitted diseases and neonatal herpes' summarises the current scientific position on the diagnosis and treatment of a great number of sexually transmitted diseases (STD) and neonatal herpes. Symptomatic treatment of suspected Chlamydia trachomatis infection and gonorrhoea without previous diagnosis is not recommended. Treatment can be started immediately, once samples have been taken. Risk groups eligible for screening or proactive testing on C. trachomatis infection include: partners of C. trachomatis-positive persons, visitors of STD clinics, women who will undergo an abortion, mothers of newborns with conjunctivitis or pneumonitis, young persons of Surinam or Antillean descent, young women with new relationships and individuals whose history indicates risky sexual behaviour. A period of 3 months can be adopted between a risky contact and the HIV test (this used to be 6 months), unless post-exposure prophylaxis was used. For the treatment of early syphilis no distinction is drawn between HIV-infected and non-HIV-infected persons. It is no longer recommended that women in labour with a history of genital herpes are tested for the herpes simplex virus. Virological testing of the neonate is only advised if the mother shows signs of genital herpes during delivery.
