The camps manned by medical officers and Community Health Providers (CHPs) are providing HIV services, and distribution of condoms.
"We are trying to say, young people, this is not a joke, it is something we can work together. Let us have fun, but now we are responsible for our lives".
Data notes that though Kenya has made sufficient progress in the war against HIV, the progress is threatened by the number of young people being infected by HIV.
At least more than 75 percent of new infections in the country, representing about 22,000 cases, is among young people aged is among young people aged 18 and 34.
Kenya has the seventh burden of HIV globally, with 1.4 million people living with HIV.
New HIV infections reduced by 78.2 percent (101,448) in 2013, to 22, 154 in 2023.
At least 75 percent of new infections occur among adolescents and young adults aged 15 to 34 years, according to 2022 data.
"We want to ensure young people are having fun, but in a responsible manner. We have been providing services and giving condoms for those who are sexually active and trying to insist they're safer," she added.
Additionally, young girls are acquiring HPV, which causes cervical cancer.
Masha added that the majority of young people do not know that unprotected sex puts them at risk of cervical cancer when they acquire HPV.
"The whole of the week we are educating them (young people) that it is not only pregnancy, it is not only HIV but other diseases that come with unprotected sex," said Masha, during youth sensitisation at the Naivasha rally.
Prof Mugo said HPV causes about 99 per cent of cervical cancer, reported at a tender age of 25 years.
The researcher pleaded with parents to take their children for HPV jab, to prevent cancer.
"My conversation with parents and guardians is that it is irresponsible to fail and get girls vaccinated. Cervical cancer is not a disease to wish to anybody. It bleeds and kills, and needs not to happen," said Prof Mugo.
She added, "For younger women, please go for screening, we can prevent it in outpatient clinics".
