While COVID19- creates complicated problems and changes relationships between humans, we experienced several problems in accomplishing our role and task, which consist of sensitizing people.

We decided to experiment with a new method and carry out our functions in a different form. To this end, we created several groups for different provinces in Iran, and started drafting new educational content such as posters, animations and presentations, in an attempt to maintain our connections with our customers and audience. The idea eventually came to fruition, and we now have several groups with more members than we had prior to COVID  19.

Today, we publish new content every day regarding the problems that prevail in the field, and while exerting all efforts possible to solve them.

We have faith in our work and hope for the future. We are convinced that together, we shall grow stronger every moment of every day, even in light of COVID 19. And the successful experience we had is proof.
