Sexual use: screening, sampling and prevention
This documentary entry combines infections whose transmission can be sexual. An infection may be silent; symptoms alone do not allow for choice or interpretation of screening. The relevant samples depend on the exposures and the sites concerned.
The distinctions that change reading
Sampling sites
A blood or urinary test does not automatically cover all agents and sites.
Prevention
The means available differ according to infection: barrier protection, vaccination, drug screening and prevention when indicated.
Practical issues
Is the absence of symptoms sufficient to exclude an STI?
No. Screening can be relevant even without visible signs.
Before interpreting a sheet
Find the agent's name, the indicated routes and the primary source. Then check the date and territory of this source. A section helps to compare; it does not determine a person's medical conduct.
