Utilising the latest epidemiological facts from BC, we now have supplied answers to the seven typical STI questions lately asked during the news.
1. is STIs actually increasing? Those that?
Yes, STIs are on the rise. Apart from HIV, other sexually transmitted infection were growing in BC.
Chlamydia is the most common STI in BC, and consistently build: In 2017, there had been 15,646 covers of chlamydia reported in BC (325 circumstances per 100,000 anyone), such as problems of both penile and extra-genital chlamydia.
