Objective: Find out whether the circadian rhythm has an impact on incidence of STD by compiling statistics on the average number of cases of STD in Latvia between 2001 and 2019 and comparing with foreign studies.
Material and methods: In 2020, data collected by the Centre for Disease Prevention and Control (CDPC) on the average number of cases of sexual-ly transmitted diseases (gonorrhoea, chlamydiosis, syphilis, scabies) in Latvia broken down in months and seasons during the period between 2001 and 2019, and acomparison has been made with eight foreign studies.
Findings: Upon differentiating between incidence of gonorrhoea, chlamydiosis, syphilis, and scabies from 2001 until 2019, broken down by months, the highest incidence is observed in December which be-gins to decline until March. In April there is arise in the incidence of STD, while it begins to drop in May again until it reaches its lowest point in June. Upon differentiating between the number of cases of gonorrhoea, chlamydiosis, syphilis, and scabies form 2001 until 2019, when broken down by seasons, it was established that the lowest incidence of STD is in the third quarter (summer) whereas the highest incidence is in the fourth and first quarters (fall and winter).
Conclusions: The impact of the circadian rhythm on the incidence of STDs in Latvia cannot be denied. Save for the study conducted in Scotland, the rise of STD incidence during the fourth quarter in common in all studies, just like in Latvia. It can be explained by the endogenous, annual rhythm of human reproduc-tion and higher levels of testosterone, as well as more frequent visits to medical facilities after summer. In Latvia arise of incidence was observed in the first quarter, which was not registered in the studies of other countries. Such discrepancy can be explained by late clinical diagnostics. The lowest incidence of STDs in Latvia is in the third quarter, because the summer is short in Latvia and people visit medical facilities less frequently then leaving examination of their health for the fall.
