AB - <p style="text-align: justify;">While the spread of COVID-19 in China is under control, the pandemic is developing rapidly around the world. Due to the normal migration
of population, China is facing the high risk from imported cases. The potential
specific medicine and vaccine are still in the process of clinical trials. Currently,
controlling the impact of imported cases is the key to prevent new outbreak
of COVID-19 in China. In this paper, we propose two impulsive systems to
describe the impact of multilateral imported cases of COVID-19. Based on the
published data, we simulate and analyze the epidemic trends under different
control strategies. In particular, we compare four different scenarios and show
the corresponding medical burden. The results can be useful in designing appropriate control strategy for imported cases in practice.</p>
