[Chlamydia carrier--symptomless or unfaithful?].

: While chlamydia is the most common cause of sexually transmitted infection both in Finland and globally, it is not possible to determine the traditionally understood incubation period or the time to the development of clinical symptoms. Although the knowledge about the disease burden of chlamydial infections has grown and its diagnosis and treatment have dramatically improved, there is no indication of chlamydia epidemics calming down. Well over 10000 yearly cases are still diagnosed in Finland. Active testing or screening still remains essential.
