Sexually transmitted infections (STIs)
• More than 1 million sexually transmitted infections (STIs) are acquired every day worldwide
• Each year, there are an estimated 376 million new infections with 1 of 4 STIs: chlamydia, gonorrhoea, syphilis and trichomoniasis.
• More than 500 million people are estimated to have genital infection with herpes simplex virus (HSV)
• More than 290 million women have a human papillomavirus (HPV) infection
• The majority of STIs have no symptoms or only mild symptoms that may not be recognized as an STI.
• STIs such as HSV type 2 and syphilis can increase the risk of HIV acquisition.
• In some cases, STIs can have serious reproductive health consequences beyond the immediate impact of the infection itself
