The Mexican Institute of Social Security (IMSS) recommended that in this return to classes the use of antibacterial gel and face masks be maintained in classrooms, as well as healthy distance, frequent hand washing and reinforce in minors that objects of work are for personal use.Despite the continuous reduction in cases and the fact that minors have been immunized, Clara Elizabeth González Rosas, coordinator of First Level Medical Programs of the IMSS Health Promotion Division, affirmed that although some have already had the experience of returning to classes after confinement, it is necessary to reinforce preventive measures, especially in children who will enter school for the first time, as well as in their parents or guardians.The preventive care that must be taken by minors at school ranges from their vision, spine and nutrition, to mental health and socio-emotional needs as a result of the pandemic.Judith Gutiérrez Aguilar, coordinator of IMSS First Level Medical Programs, said that children, being subjected to continuous hours of reading or continuously seeing the blackboard, screens and notebooks, should rest their eyes every 15 minutes, moving their eyes away and bringing them closer. back to the notebook.In cases where minors already wear glasses, cleaning them is the same, only you have to avoid leaving them anywhere and they get contaminated, and you don't have to lend them.Regarding the care of the spine, the specialist raised the need for the backpack to not have more than 10 or 15 percent of the child's weight, it must have thick straps and it must be carried above the waist."The child should not carry the backpack for more than 15 minutes, if so, we will have to think of an accessory with which he can pull it," she indicated.Gutiérrez Aguilar pointed out that an ideal diet encompasses important aspects such as health;in the case of fruits and vegetables, they must be disinfected and well washed;if they were prepared the day before, they should be kept refrigerated overnight;have a variety of foods with protein content and in amounts that take into account the age and specific requirements of the child.Another important aspect to take into account when going back to school, he added, is mental health, since there are children who have experienced loss of family members during the pandemic, economic difficulties, or may have developed fears.“You have to listen to them, let them express themselves in different ways: verbally, in writing or through drawings.When the teachers identify that there is some abnormality, the general group intervention will be seen, the specific intervention and that child who requires it, will be channeled to psychological support”, stressed Gutiérrez Aguilar.On August 8, Social Security launched the PREVENIMSS+ program, whose main objective is to prevent diseases through systematized actions;In the case of minors, their parents or guardians can take them to their Family Medicine Unit with their National Health Card, so that they can be instructed on other preventive measures, in order to avoid various diseases, such as meningeal tuberculosis, infections, measles and rubella, which are preventable by vaccination, among others.
