Chapter 12 – Sexually Transmissible Infections (STIs)

Summary of chapter

The term sexually transmissible infection (STI) is used to describe infections that are solely or commonly spread through sexual contact. Most STIs are asymptomatic or minimally symptomatic in their infectious stages, which increases the likelihood of onward spread of the infection. Most STIs are simple infections and easily treated.

A comprehensive public health approach to the management and control of STIs includes health promotion and education, access to clinical care, screening and testing, contact tracing, treatment, surveillance, notification and vaccination. A full discussion of these elements is beyond the scope of this publication, which is designed to provide a basic practical clinical approach to the diagnosis and management of STIs.

For a full discussion about STIs, see Australasian Sexual Health Alliance – Australian STI Management Guidelines for use in Primary Care website.

The STIs we will consider in this chapter are:

Chlamydia Gonorrhoea Mycoplasma genitalium infection Trichomoniasis Genital herpes Genital warts Hepatitis A Hepatitis B Hepatitis C Syphilis Human Immunodeficiency Virus

Genital symptoms may have causes other than STIs, although these are not discussed in this chapter. Candida and bacterial vaginosis are discussed in Chapter 4: The Vagina and Vulva (see Bacterial Vaginosis), and Pelvic Inflammatory Disease (PID) is discussed in Chapter 13: Pelvic Inflammatory Disease.
