Covid 19 and It’s Mathematical Modeling with Epidemic Prediction

Since receiving unexplained pneumonia patients at the Jinyintan Hospital in Wuhan, China in December 2019, the new corona virus or Cvoid 19 has rapidly spread in Wuhan. China and spread to the entire China and some neighboring countries. We establish the dynamics model of infectious diseases and time series model to predict the trend and short-term prediction of the transmission of COVID-19. Which will be conducive to the intervention and prevention of COVID-19 by departments at all levels in mainland China and buy more time for clinical trials.

Above all based on the transmission mechanism of COVID-19 in the population and the implemented prevention and control measures. We establish the dynamic models of the six chambers. Establish the time series models based on different mathematical formulas according to the variation law of the original data.

The results based on time series analysis and kinetic model analysis show that the cumulative diagnosis of pneumonia of COVID-19 in mainland China can reach 36,343 after one week (February 8, 2020) and the number of basic regeneration can reach 4.01.

Cumulative Number of Confirmed Patient Diagnosed

The cumulative number of confirmed diagnoses will reach a peak of 87,701 on March 15, 2020. The number of basic regeneration in Wuhan will reach 4.3. The cumulative number of confirmed cases in Wuhan will reach peak at 76,982 on March 20. Whether in Mainland China or Wuhan. Both the infection rate and the basic regeneration number of COVID-19 continue to decline. For Instance the results of the sensitivity analysis show that the time it takes for a suspected population to be diagnosed as a confirmed population. It can have a significant impact on the peak size and duration of the cumulative number of diagnoses. Increased mortality leads to additional cases of pneumonia, while increased cure rates are not sensitive to the cumulative number of confirmed cases.

Chinese governments at various levels have intervened in many ways to control the epidemic. According to the results of the model analysis. We believe that the emergency intervention measures adopted in the early stage of the epidemic. Such as blocking Wuhan. Restricting the flow of people in Hubei province. And increasing the support to Wuhan. Had a crucial restraining effect on the original spread of the epidemic. It is a very effective prevention and treatment method to continue to increase investment in various medical resources to ensure that suspected patients can be diagnosed and treated in a timely manner.

Sensitivity analysis to Covid 19

Based on the results of the sensitivity analysis. Moreover we believe that enhanced treatment of the bodies of deceased patients can be effective. It ensuring that the bodies themselves and the process do not result in additional viral infections. Therefore once the pneumonia patients with the COVID-19 are cured. The antibodies left in their bodies may prevent them from re-infecting COVID-19 for a longer period of time.

All of this modelling could be transfered into programming such as Spring in Java Programming and this article originally qoute from this article.
