Pandemic cycles are becoming shorter and shorter. From severe acute respiratory syndrome (SARS) in 2002, influenza A (H1N1 virus) in 2009, and Middle East respiratory syndrome coronavirus (MERS-CoV) in 2015 to COVID-19 in December 2019, we have experienced periodic pandemics in the 21st century, and the danger of a new pandemic is always around us (Figure 1). Although therapeutics and vaccines for COVID-19 have been developed, their safety for children has yet to be fully established. It is unknown when a new virus may emerge. Children are particularly vulnerable to infectious diseases, and when an infectious disease occurs, they constitute the most challenging group to ensure the safety and efficacy of a vaccine. Therefore, flexible responses to care for children are required when a new pandemic crisis occurs. These nursing coping strategies may include appropriate isolation, nursing, and education for children and their families.

Traditionally, pediatric nursing care has occurred in settings centered on hospitals and schools. However, in the COVID-19 situation, everything is non-face-to-face. The traditional pediatric nursing system stopped working, as it became too difficult to care for children in hospitals and schools. Therefore, developing new pediatric nursing care intervention methods for non-face-to-face situations became necessary. As a representative method, educational programs using online webinars, the metaverse, and similar technologies, can be cited as examples. This educational method can be applied to the development of non-face-to-face education programs for children with chronic diseases and for pre- and post-surgery education. Education using the metaverse has already been implemented in some hospitals, and these non- face-to-face programs have been shown to be effective in educating children with chronic diseases. Parents can also participate in the nursing care of their children. Unlike their parents' generation, children born after 2000 are digital natives. If we find various ways to deliver nursing interventions while satisfying their needs effectively, it will stimulate children's curiosity, arouse interest, and induce active participation.

In addition, various programs can be applied to education for new nurses and children. In addition to education using online webinars, as described above, augmented reality or virtual reality can be applied to emergencies and new nurse education programs for children's basic nursing.

Children and young people who receive pediatric nursing care belong to the so-called Generation Z. They are digital natives and actively communicate online. However, only 45% of Generation Z participants in an APA study from 2018 reported having exceptional or excellent mental health [1]. In other words, Generation Z did not have good mental health even before COVID-19. The impact of the COVID-19 pandemic on individuals, families, and communities has had multifaceted effects on children [2]. In particular, the isolation caused by COVID-19 can negatively impact children's mental health [3]. In addition, prolonged social isolation, as occurred during the response to COVID-19, can adversely affect children's mental health, leaving many students in a mental crisis. Some children are sensitive, afraid, or violent, in addition to having depression, anxiety, and high levels of stress [4]. For them, it is necessary to develop effective, age-appropriate crisis communication techniques, appropriate stress relief methods, and mental health care.

We have all been dealing with the crisis of COVID-19, and now we are waiting for its end. The new normal has already been established, and we cannot return to the pre-COVID-19 situation. The future is uncertain, but pediatric nurses must strive for the health of children and their families. We now have to adapt to the new era and be flexible. In order to deal with a new pandemic after COVID-19, we also need to devise an appropriate strategy. That is the mission and duty of a pediatric nurse.
