The Internet has become an important tool for many people with health concerns [1,2] specially for adolescents [3,4]. Concerns about confidentiality, coupled with the stigma and shame associated with some conditions, specially sexually transmitted infections and other Health related problems make the internet a safe enviroment for adolescents to seek for information. This is thought to lead to an under-utilization of traditionally providers as the primary care health services.

These consultations, often made by young people, include sexual and reproductive health problems [5] and mental health disorders [6]. This can be a major problem, since the under-utilization of primary care services for certain topics and the search for advice on the Internet that is not usually trusted can subsequently lead to health complications that may require more expensive specialized medical interventions. long-term and, therefore, can translate into an increase in healthcare costs [7].

School programmes as Salut i Escola, have had as an objective all these years, to provide a more readily access to health care practitioners in order to improve their health related problems, doubts in sexual orientation, mental Health issues, drug related consultations and prevention of high-risk sexual behaviors by collaboration with educational centers and the community health services present in the territory.

Nowadays, with all the Advanced Technology we dispose, and because of the enormous amount of unstructured online content and the importance and difficulty of determining health information quality[8], it is almost obligatory to try to provide access to verified and make this study a tool to engage with adolescents and rovide them with accedd to trustful information.

Therefore, the Salut i Escola program together with the software of a well known company AGH Health, have been tried to minimize hesitation in seeking health advice through a chat application called Xatjove [9]. This is an asynchronous mobile text-based communication agent that connects users with healthcare professionals. These professionals provide appropriate guidance and advice to users in order to help them take Health related decisions.

As an anonymous digital health intervention, XatJove has the potential to address cost ineffectiveness caused by under-utilization health services in terms of shameful and stigmatized disorders.

According to a pilot study on e-Consultation (then known as WebGP), some of the top ten reasons for consultation of patients using this virtual tool included cystitis and problems with contraception (in women) [10]. It is known that if ignored, these conditions can lead to more serious, unwanted and costly complications (lack of contraception can lead to unwanted pregnancies and sexually transmitted infections) [11,12]. The fact that users routinely reported these problems through interventions health services such as e-Consultation is a positive sign in terms of an increased use of health services for sensitive but important conditions.

At the current time of the health crisis caused by the Covid-19 pandemic and to reduce the risk of infection, it makes more sense than ever to try to avoid face-to-face consultations of nursing professionals in institutes and also the visits of young people. to Primary Care Centers (CAPs). Great care must be taken that this does not mean a reduction in consultations on topics related to the health and school program. In addition, the health crisis is expected to lead to an increase in the need for emotional support by young people and agile tools are needed that use technologies that this sector of the population dominates and uses on a regular basis [13].
