CONCLUSION

Our data showed that in addition to the characteristics of the virus itself, the introduced epidemiological measures, as well as their timeliness, are important for preventing the spread of COVID infection 19. Mass events such as sports matches, elections, big celebrations and traveling, especially traffic between states can significantly determine the epidemiological course. It remains to be seen whether the liberal approach we have seen in Sweden is justified, whether there will be the emergence of collective immunity and how important it will be, considering opening of borders with countries that have not implemented the same epidemiological methods. Meantime we will have to adopt the new standards of ”normal” life in coexistence with the virus with adequate epidemiological measures, at least until a vaccine or effective drug are found.
