Aim.

Describe the incidence, transmission mechanism, and nutritional and psychological consequences of SARS-CoV2 / COVID-19 in children.

Methodology.

A systematic review of information about the transmission and pathogenic mechanism of SARS-CoV-2 in children aged 7 and 14 years was carried out, in search engines such as Crosref, PubMed, and journals indexed in SciELO, using keywords such as: children, SARS- CoV-2, COVID-19, transmission, incidence. Given that the consequences are very diverse in the health of children, more emphasis is placed on aspects such as the negative impact on a nutritional and psychological level.

Results.

Cases of SARS-CoV-2 and / or COVID-19 have only reached 2.02% of confirmed cases in Mexico, mostly symptomatic, without the need for hospitalization. It may be due to the fact that children have a lower expression of ACE2 receptors, an inatural immune response, a greater presence of IGM, few comorbidities, nutritionally the greatest impact is in children with obesity and on a psychological level, most likely due to confinement and impact of not being able to have a school education.

Conclusion.

For now, without serious clinical repercussion in children, but in social interaction, they do not play, they lack development at a nutritional level that makes them more vulnerable and psychological, with negative consequences on their health. Not knowing how to deal with the conditions that are now living can have consequences in non-positive psychiatric-psychological disorders.
