A Mathematical Prediction Model of Infectious Diseases Considering Vaccine and Temperature, And its Prediction in Hong Kong

Since 2020, COVID-19 has launched a rather difficult challenge in public health all over the world. For the current situation of COVID-19 outbreaks in various places, predicting the trend of COVID-19 plays a vital role in later policy-making, allocating medical materials, and developing the economy and society. Although there may be corresponding specific drugs soon, which can reduce the mortality of COVID-19 to a relatively low level, but the main popular Omicron BA.1 and BA.2 strain is highly infectious, which has a great impact on the elderly population, so COVID-19 cannot be equated with general influenza. This paper aims to predict the trend of the number of infections over time and the final number of infections from the fifth wave of epidemic in Hong Kong. To establish a more practical infection model, this paper introduces an infectious disease transmission model with the influence of temperature and vaccine. The model shows that the fifth wave of the epidemic in Hong Kong will end at the end of April 2022. At that time, the cumulative number of infections is expected to reach about 1.6 million. By formulating and implementing reasonable policies, the final number of infections can be controlled at about 1.1 million. Therefore, we hope that the policymakers and managers of COVID-19 in Hong Kong will formulate and adopt reasonable measures to control these policies.Funding Information: This work was supported by the Natural Science Foundation of Hebei Province [A2021210011], the Department of Education of Hebei Province [ZD2021335], Innovation and entrepreneurship plan for College Students [2021101070194] and the National Natural Science Foundation of China [Nos.11602151, 11872253].Conflict of Interests: The authors declare that they have no known competing financial inter- ests or personal relationships that could have appeared to influence the work reported in this paper.
