Young people aged 15 to 24 are the biggest contributors to new HIV / AIDS infections, the National AIDS Council said.
The AASB said that of the 52,000 deaths caused by HIV / AIDS in 2017, 17,000 were young people.
Deputy Director John Kimigwi said early pregnancies reported at Kilifi five months ago increased from 13,000 to 17,850.
He said the number is alarming and is contributing to the spread of HIV and AIDS in the county, which is classified as a country of high poverty.
"In the country, we continue the war on HIV, but we still have challenges," he said.
Mr. Kimigwi spoke at the International Day of Condoms held Wednesday at Pwani University.
Maureen Mwangovya, member of Kilifi's Executive Committee on Gender, Culture and Youth, also attended the event.

The king and queen of condoms in Kenya were also present and showed how to use condoms.
The deputy director said that it was necessary to define a strategy to reach young people to reduce the spread of HIV.
"We need to work together to develop strategies to help young people under the age of 24 to have their lives and health healthy," Kimigwi said.
The CEC said the new statistics on early pregnancy were alarming because they clearly indicated that young people were having unprotected sex.
She added that if no action was taken in the next five years, that number would destroy the younger generation.
"It is important to reduce the number of teenage pregnancies, as young people aged 15 to 19 are increasingly contracting HIV / AIDS," she said.
In Kilifi, she said that HIV / AIDS among youth was 38% and the majority of those affected were girls.
Thousands of condoms have also been distributed in the region.
