Why are some common STI's neglected over others?
Gwenda Hughes from the Centre for Infectious Disease Surveillance and Control at Public Health UK spoke about the surveillance of neglected STI's this morning.
On average every year, there are around 358 million new infections of four curable STI's, which one do you think is the highest number?
Syphilis, Chlamydia, Gonorrhoea, or Trichomoniasis?
6.6 Million Syphillis infections, 78 Million Gonorrhoea, 131 Million Chlamydia and at the highest; 143 million Trichomoniasis.
Caused by the parasite Trichomonas vaginalis, it is nine times more prevalent in women and with the associated risk factors of lower socio economic factors, lower levels of education and increased number of partners.
With poor specificity on wet smears, limited surveillance data, and knowledge gaps in racial ethnic disparity target groups, this is an STI that would benefit further research.
In Sydney we do see limited infections, and this is more common in rural Australian settings, and higher amount in Aboriginal Torres Strait Islanders.
Lymphogranuloma Venerum (LGV) - is commonly tested in Australia with positive rectal CT infections, but one point I thought was interesting the presentation was in Germany that out of 154 MSM with positive CT infection not only had 17% had LGV rectally, but 15% had pharyngeal LGV.
Would this number be similar in Australia with the Sydney study (David Templeton) showing 3 out of 75 positive LGV with rectal CT.
Could we do pharyngeal LGV testing with positive CT Pharyngeal PCR swabs?
