It is suggested by CPS infection in the European Union that, in the past 10 years, the European chlamydia patients has doubled, 3/4 of the emerging infectious diseases occur in young group with the age of 15-24 years old, most are females.
ECDC has declared their chlamydia monitoring result, which involves the STD infection status in its EU members for the past 20 years. As the first STI comprehensive report, some great countries like France, Italy and German are not included into the statistical data, and other countries, especially Former Soviet Republics, its statistical data may be underestimated. And the major chlamydia infection data is provided by the following countries: Denmark, Norway, Sweden and England.
In the years of 2000-2009, it is showed by the countries with a continuous report about STI that, chlamydia infection incidence has doubled (from 143 cases/100,000 people in 2000 increase to 332 cases/100,000 people in 2009), among them, 60% are female. In 2009, the European incidence is 185 cases/ 100,000 people. ECDC suggests that, the real incidence is much higher than this number, and chlamydia also rank first in STI. And people around 20 - 24 years old are the major group (from 38% in 2000 increase to 41% in 2009), and the next age group is 15 - 19 years old, its infection rate increase from 25% in 2000 to 34% in 2009. ECDC think that this increase is owing to a strengthen monitoring service towards the lower age group.
ECDC emphasizes that it takes cautious to account for the age and sex distribution, because this detection is mainly direct at young group, which strongly influence the result. On the other hand, ECDC indicates that female has a higher incidence than male. It is suggested that female left their chlamydia disease untreated will cause great damage for them, because no symptoms manifest in female, which even cause their infertility problem.
