The above figures exclude data from other sources other than sexual health clinics. Health workers believe numbers have risen dramatically since 2008 especially in cases of chlamydia.
The numbers for those being checked for the infection is staggering and represent a 14% rise on the previous year. Official figures show the largest increase in testing for chlamydia is among the youngest age group. The latest statistics saw a dramatic rise of 21% in tests on young men aged 16-24 and in young women of the same age there was an increase of 16% recorded in the same period.
A sexual health clinic source is speaking out anonymously because of her concerns of youngsters putting themselves at risk. She paints a bleak picture of irresponsible behaviour.
"There are more young boys and girls aged 12 and 13 having sex these days than ever before," she said.
"I don't know why they are starting so young but we see the fallout. (Could this also be part of the reason?)
"The knock-on effect is that cases of underage pregnancies and kids having chlamydia and other STIs rise. In many clinics the staff can't cope with the numbers.
"We are seeing a lot of teens with STIs or coming in for abortions.
"I have been told stories about 'daisy-chaining' where groups of teenagers from both sexes go to someone's house while the parents are out and swap partners until every boy has been with every girl.
"The problem is often fuelled by alcohol which they consume at parties and sometimes younger teens can be forced into having sex.
"If they're thought to be mature enough then patients don't need to have their parents with them when they're being treated for STIs or having abortions.
"They can also tell them not to send anything to their GP or house.
"The kids can get the bus into town for an abortion during the day and get back up the road for their dinner without their parents ever knowing."
Tory health spokesperson Mary Scanlon MSP said teens must be educated about the dangers of practices such as daisy-chaining.
That's nonsense. It's sex education which has stimulated the very young to experiment to this degree, along with the fact that they can dictate to health professionals that they don't want parents to be informed. Who decides if an under 16-year-old is mature? I thought all under 16-year-olds were called children and until they reach the age of 16 they are the full responsibility of their parents.
These children have no barriers to sex. There is no punishment for behaving in this manner at such a young age. For many of us over say 40, the very thought that your parents would be told or find out was enough to make you run a mile. As for acquiring an STI, I would have been mortified, even when a young adult.
Sex education in schools hasn't produced good sexual behaviour in children - certainly not going by these figures - so isn't it time it was given less of a priority and more time spent on learning how to read, write (plus spell) and add well enough to gain adequate employment when they leave education?
